James Watt and the Invention of the Steam Engine

Until a little more than one hundred years ago, the chief power used in the production of food, clothing, and shelter was hand power. Cattle and horses were used to cultivate the fields. Windmills and water wheels were employed to grind corn and wheat. But most tools and machines were worked by hand.

JAMES WATT

Men had, for many years, dreamed of a new power which would be more useful than either work animals, sails, windmills, or water wheels. This new power was steam. Yet no one had been able to apply the power of steam so that it would grind corn and wheat, spin and weave cotton and wool, or do any useful thing at all. The man who succeeded in giving to the world this new power was James Watt. Steam now propels ships over the Atlantic in less than a week. It speeds express trains across our continent in ninety hours, and it does a thousand other wonderful and useful things.

Childhood and Early Education

James Watt was born in 1736, at Greenock, Scotland, not far from Glasgow. His early education was received at home, his mother giving him lessons in reading, and teaching him to draw with pencil and chalk. His father drilled him in arithmetic and encouraged him in the use of tools. When at length James went to school, he did not at first get along well. This was due to illness which often kept him at home for weeks at a time. Still, he always did well in arithmetic and geometry, and after the age of fourteen he made rapid progress in all his studies.

Even as a small boy, James was fond of tinkering with things. This fondness was not always appreciated, as is shown by a remark of an aunt: "James Watt, I never saw such an idle boy; take a book or employ yourself usefully; for the last hour you have not spoken a word, but taken off the lid of that kettle and put it on again, holding now a cup and now a silver spoon over the steam, watching how it rises from the spout, and catching the drops of water it turns into. Are you not ashamed to spend your time in this way?"

Much of his time, as he grew older and stronger, was spent in his father's shop, where supplies for ships were kept, and where ship repairing was done. He had a small forge and also a workbench of his own. Here he fashioned cranes, pulleys, and pumps, and learned to work with different metals and woods. So skillful was he that the men remarked, "James has a fortune at his fingers' ends."

WATT AND THE TEAKETTLE.

The time at last came for choosing a trade. The father had wished James to follow him in his own business. But Mr. Watt had recently lost considerable money, and it now seemed best for the youth to choose a trade in which he could use his mechanical talents. So James set out for Glasgow to become an instrument maker.

Learning Instrument Making

He entered the service of a mechanic who dignified himself with the name of "optician." This mechanic, though the best in Glasgow, was a sort of Jack-of-all-trades, and earned a simple living by mending spectacles, repairing fiddles, and making fishing tackle. Watt was useful enough to his master, but there was little that a skillful boy could learn from such a workman. So he decided to seek a teacher in London.

There were plenty of instrument makers in London, but they were bound together in a guild. A boy wishing to learn the trade must serve from five to seven years. Watt had no desire to bind himself for so long a period. He wished to learn what he needed to know in the shortest possible time; he wanted a "short cut." Master workman after master workman for this reason turned him away. Only after many weeks did he find a master who was willing to take him. For a year's instruction, he paid one hundred dollars and gave the proceeds of his labor. The hours in the London shops were long. "We work," wrote Watt, "to nine o'clock every night, except Saturdays." To relieve his father of the burden of supporting him, he got up early and did extra work. Towards the end of the year he wrote, with no little pride: "I shall be able to get my bread anywhere, as I am now able to work as well as most journeymen, though I am not so quick as many."

Jack-of-all-trades

In order to open a shop of his own, Watt returned to Glasgow. He was opposed in this by the hammermen's guild. The hammermen said that he had not served an apprenticeship and had no right to set up in business. They would have succeeded in keeping him from making a start, had not a friend, a teacher in the University of Glasgow, come to his aid, providing him with a shop in a small room of one of the college buildings.

Watt soon became a Jack-of-all-trades. He cleaned and repaired instruments for the university. Falling into the ways of his first master, he made and sold spectacles and fishing tackle. Though he had no ear for music and scarcely knew one note from another, he turned his hand to making organs. So successful was he, that many "dumb flutes and gouty harps, dislocated violins, and fractured guitars" came to him to be cured of their ills.

All the while, Watt spent his leisure time in reading. The college library was close at hand, so there was no lack of books. Chemistry, mathematics, and mechanics were studied. By learning all he could and by doing everything well, Watt came to be known as a man "who knew much and who could make anything."

Captured by Steam

Coal and tin mining had for a long time been important industries of Great Britain. Shallow mines were easy to work. Men and women carried out the coal or tin ore in buckets, by winding stairs. Or a windlass was used, turned by hand or with the aid of a horse. Water was taken out in the same way. As the shallow mines became exhausted, deeper ones were opened. The deeper the mine, the harder it was to lift out the coal or tin ore. Into these deeper mines also came quantities of water, flooding many of them. Unless a machine should be invented which could be run at a small cost, to pump out the water and to hoist the coal or tin, these mines would have to be closed. The need of such a machine led to the invention of the first successful steam engine.

Watt first heard of the steam engine in 1759. The idea captivated him, and he began to read how others had tried to make successful engines. Finding that the best books on steam and "fire engines," as they were then called, were in Italian and German, he took up the study of these languages.

In an Italian book he read about Branca's steam engine, invented in 1629. Branca's engine was little more than a toy, no use being made of it, except to pulverize saltpeter and do other simple things of like sort.

BRANCA'S STEAM ENGINE OF 1629.

In a German book he read about Papin's engine, which was invented in 1690. In Papin's engine steam was admitted into the cylinder. The steam was then allowed to condense, that is, turn back into water. This formed a vacuum, or space without any air in it, under the piston. The weight of the atmosphere, which is about fourteen pounds to the square inch, on the upper side of the piston, forced it down, and the descending piston raised a weight fastened to the rope. Papin never went further than the making of a model. But his idea of using steam to make a vacuum, and of using the pressure of the atmosphere to force down a piston was applied a few years later with some success by Thomas Newcomen.

PAPIN'S ENGINE.

Newcomen made his first engine in 1705. Although big and awkward, a number were used in England to pump out the water at the mines. But they could not be used in deep mines, as they could lift only six or seven pounds for each square inch of the piston. They worked slowly, making only about fifteen strokes a minute, and they were expensive also, a single engine burning fifteen thousand dollars' worth of coal in a year.

Finding the Trouble

Watt had been thinking about steam for four or five years before he saw one of Newcomen's engines. Then it was only a model of one, brought to him from the university for repair. When he had repaired the model, he started it to going. It made a few strokes and stopped. There was no more steam. The boiler seemed big enough, so he blew up the fire. The engine now ran all right, but it required much fuel and used up quantities of steam, though the load on the side of the pump was light. Most men would have thought nothing of this, and would have sent the model back to the university. But that was not Watt's way. Everything he did not understand was for him a subject for study, and he never stopped until he understood. So he set to work to discover why the engine used so much steam.

NEWCOMEN'S ENGINE.

Steam was used, you will remember, to make a vacuum in the cylinder. Watt found that to drive out the air and water, enough steam had to be let into the cylinder to fill it four times. Why was this? First, the cylinder was exposed to the air, which chilled it. The cold cylinder itself, before it was warm, changed considerable steam into water. Second, cold water was poured into the cylinder to condense the steam, and this made the cylinder cold again. Watt estimated that three fourths of all the steam used was thus wasted in heating and reheating the cylinder. Here was the trouble with Newcomen's engine. Watt saw that, to remedy this defect, a way must be found to keep the cylinder always as hot as the steam which entered it, and the vacuum must be made in the cylinder, without cooling it.

Making the Invention

Watt spent much time and money in making experiments, but nothing he tried succeeded. "Nature has a weak side," he was fond of saying, "if we can only find it out." So he went on day after day, following now this and now that false hope.

"One Sunday afternoon early in 1765," writes Watt, "I had gone to take a walk in the Green of Glasgow. I was thinking upon the engine and about how to save the heat in the cylinder, when the idea came into my mind that steam was an elastic body and would run into a vacuum. If connection was made between the cylinder and a tank from which the air had been pumped, the steam would pass into the empty tank and might there be condensed without cooling the cylinder. I then saw that I must get rid of the condensed steam and of the water used in condensing it. It occurred to me this could be done by using pumps."

With a separate condenser in mind, to get rid of the steam after it had done its work, without cooling the cylinder, other important improvements were thought of. In Newcomen's engine, the upper end of the cylinder was open to let the air act upon the piston. Watt now planned to put an air-tight cover over the end of the cylinder, with a hole for the piston rod to slide through, and to let steam in above the piston to act upon it, instead of the air. This change made Newcomen's atmospheric engine into a steam engine. In Newcomen's engine the power was the pressure of the atmosphere upon the piston, and this power acted in one direction only. In Watt's engine steam was the power, and the piston was shoved both up and down by it; hence Watt's engine was called a double-acting engine.

"All these improvements," says Watt, "followed in quick succession, so that in the course of one or two days the invention was . . . complete in my mind."

The next step was to make a model, to put the invention into working form. Making the drawings was easy, but to carry them out was hard. A lack of good workmen was the chief difficulty. There were no skilled mechanics in those days, nor self-acting, tool-making machines; everything had to be made by hand. Blacksmiths and tinners were the only men that could be hired, and they were bungling workers even at their own trades. After eight months of racking labor, the model was ready to start. It worked, but despite all Watt's care, it "sniffed at many joints." The condenser did not work well; the cylinder leaked, and the piston was far from being steam tight. To add to Watt's troubles, his "old White Iron man," a tinner and his best workman, died. The cross-beam broke. Nevertheless, Watt saw enough to know that he was on the right track.

Beelzebub, the Trial Engine

Watt's great need was money, for it was necessary to build a trial engine to show the value of steam power. He finally, in 1767, secured a partner who promised, for a two-thirds share in the invention, to pay a debt of five thousand dollars owed by Watt, and to bear the expense of further experiments. The partnership was formed, and Watt turned to the plans for the trial engine.

THE ENGINE BEELZEBUB, 1767.

As the trial engine neared completion, Watt's "anxiety for his approaching doom kept him sleepless at night, for his fears were even greater than his hopes." Alas! the trial engine did not work well. The new condenser acted badly. The cylinder was almost useless. The piston, despite all that could be done, leaked quantities of steam. The whole machine was a "clumsy job." From the way it wheezed, and snorted, and puffed fire and smoke, the engine was named Beelzebub. Months were spent in Wales, overhauling him, but he behaved only slightly better on second trial. Beelzebub was far from being a practical engine, and he was left for the time to rest and rust.

There is little wonder that Watt was downhearted and wrote to his friends: "Of all things in life, there is nothing more foolish than inventing." "I am resolved . . . if I can resist it, to invent no more." "To-day I enter the thirty-fifth year of my life, and I think I have hardly yet done thirty-four pence worth of good in the world."

Completing the Engine

Watt had by this time spent ten years and several thousand dollars upon his invention, but it was still only a dream. Brighter days were, however, at hand. Matthew Boulton, owner of the largest hardware factory in the world, at Soho near Birmingham, and who had working for him the best mechanics in Europe, became interested in the fire engine. In 1774, he became Watt's partner.

Meanwhile, old Beelzebub was shipped to Birmingham. The best mechanics of Soho set to work upon him. One by one the separate parts were repaired and improved. In a few months, he was ready for trial. Beelzebub puffed as much smoke and fire as ever, but with all his bluster and noise,—thanks to good workmanship, he went surprisingly well. Everyone who saw Beelzebub run felt sure that the invention would prove a success. Even modest Watt wrote to his father: "The fire engine I have invented is now going, and answers much better than any other that has yet been made, and I expect that the invention will be very beneficial to me."

WATT'S ENGINE GOVERNOR.

Though success was promised, much remained to be done to make the engine practical. It was found, for example, that if the load Beelzebub was pulling, for some cause became lighter, he would run too fast; if the load suddenly became heavier, he would run too slow.

Some way had to be found to make him run faster when there was need of more power, and to run more slowly when less power was needed. Two heavy balls were fixed to swing around an upright rod. When the engine ran fast, the upright rod turned fast, and the balls swung out and so acted as to admit less steam. When the engine ran slowly, the rod turned slowly, and the balls swung down and let in more steam. By the use of this contrivance, or the governor, Beelzebub was made to run at about the same speed, and when started and set to work, became his own engineer.

Other inventions were made, and the separate condenser, piston, and cylinder were improved. Thus, after years of thought and labor, the steam engine at length stood full grown and ready for all kinds of work.

Making the Business Pay

To make an invention is one thing. To get people to use it and so make it profitable is another. It is difficult to say which is the harder. In any case, Watt's troubles were not over.

All the time that Watt was working on his invention, mines were being flooded with water and had to be given up. Among the first orders for engines was one for a mine in Cornwall. Watt made the drawing with care, and the workmen did their best, for much depended on the first engine.

The engine was ready by the middle of 1777, and Watt went to set it up. The people were eager to get a look at the monster. Mine owners came from far and near to see it work. Many were doubtful, and some even wished that the engine might fail. But to the surprise of all it succeeded. It pumped water as they had never seen water pumped before. The size, the speed, and "the horrible noise of the engine," wrote Watt, "give satisfaction . . . and the noise seems to give great ideas of its powers." In a few days the mine was dry. It was the deepest mine in the district, and orders for engines began to come in. They came so fast that in the course of the next four or five years almost all the mines in England and Scotland were supplied.

Boulton, Watt's partner, felt from the first that the greatest field for the steam engine was in mills and factories. When orders for pumping engines fell off, Watt went to work on a factory engine. The first factory engine was built in 1782, and was for a corn mill.

A MINE ENGINE.

The use of the steam engine in mills was opposed by the millers. They saw that to put steam engines to grinding corn and wheat would do away in many places with windmills and water mills. The working people also were stirred up. They were led to believe that if the steam engine was put in mills, it would take work away from them.

"It seems," wrote Watt, "the meddlers are determined to be masters of us. To put a stop to fire-engine mills, because they come in competition with water mills, would be as absurd as to put a stop to canals, because they interfere with wagoners. . . . The argument that men are deprived of a livelihood would put a stop to the use of all machines whereby labor is saved. Carry out this argument, and we must do away with water mills themselves, and go back again to grinding corn by hand labor."

So strong was the opposition that Watt and Boulton decided to build a flour mill, to show what could be done. They built one at a cost of sixty thousand dollars, and put into it their newest and best engine. The mill attracted much attention. But it was not allowed to run long. So bitter was the feeling against the steam engine that the mill was set on fire and burned to the ground.

Though the mill was a total loss, it served its purpose. Orders for factory engines came in apace,—orders from France, from Italy, and from America. The advantages of steam power were now apparent. Water mills were stopped in the summer by the lack of water, and in the winter by frost, while steam mills worked on, by day and by night, in all kinds of weather, and in all seasons.

To bring the world to appreciate the value of the steam engine was thus a hard struggle. Down to the year 1785 every penny made from the sale of engines, amounting to more than two hundred thousand dollars, was put back into the business. Besides, large sums were borrowed. So great was the need for money that even the patents were mortgaged. Time and again it seemed as if all would be lost. More than once Watt and Boulton felt that this would be a blessing. The mine owners, for instance, refused to pay for the engines which had saved them thousands of dollars. Dishonest persons stole and used their patents. They were continually annoyed by rumors that a better engine was on the point of being completed. Efforts were even made to get Parliament to take away their patents.

"We are in the state of the old Roman," Watt wrote, "who was found guilty of raising better crops than his neighbors, and was ordered to bring before the assembly of the people his instruments of husbandry, and tell them of his arts. He complied, and when he had done, said, 'These, O Romans, are the instruments of our art, but I cannot bring into the forum the labors, the sweats, the watchings, the anxieties, the cares which produce the crops.' So everyone sees the reward which we may yet probably receive from our labors; but few consider the price we have paid for that reward, which is by no means certain."

Difficulty after difficulty was, however, battled down. Parliament refused to take away the patents. Persons who used them without right were punished. The mine owners were forced to pay what they owed. The business, after long waiting and untold distress, began to pay.

Old Age at Hearthfield

The partnership between Watt and Boulton came to an end in 1800. Watt was now well-to-do. Relieved of business cares and worry his health improved. He built a beautiful country home at Hearthfield. From there he made trips to different parts of Scotland, Wales, and England. To Hearthfield came old friends and the greatest men of England to visit him. Inventing continued to give him the greatest pleasure. A room was fitted up in the attic of the house, and there he would work for days at a time. This room remains just as it was in 1819.

Robert Fulton and the Invention of the Steamboat

On August 17, 1807, a curious crowd of people in New York gathered at a boat landing. Tied to the dock was a strange-looking craft. A smokestack rose above the deck. From the sides of the boat, there stood out queer shaped paddle wheels. Of a sudden, the clouds of smoke from the smokestack grew larger, the paddle wheels turned, and the boat, to the astonishment of all, moved. It was "Fulton's Folly," the Clermont, on her first trip to Albany.

The First Boats

The first boat used by man was probably the trunk of a fallen tree, moved about by means of a broken branch or pole. Then some savage saw that a better boat could be made by tying a number of logs together to make a raft. But rafts are hard to move, so the heart of a log was hollowed out by means of a stone ax or fire, to make a still better boat, or strips of birch bark were skillfully fastened together to form a graceful canoe. Boats were constructed also of rough-hewn boards. With such primitive craft, voyages of hundreds of miles were made up and down great rivers like the Mississippi, or along the shores of inland seas like the Great Lakes.

The Phœnicians were the first great sailors. Their boats, called galleys, were sometimes two to three hundred feet long. These were of two kinds, merchantmen and war vessels. The merchantmen were propelled partly by sails and partly by oars, but on the war vessels, when in battle, oars only were used. On a single boat there were often several hundred oarsmen or galley slaves. These galley slaves were as a rule prisoners of war. They were chained to the oar benches, and to force them to row, they were often beaten within an inch of their lives. In enormous sail-and-oar vessels the Phœnicians crossed the Mediterranean in every direction, pushed out into the Atlantic Ocean, and went as far north as England.

A MEDIEVAL GALLEY.

The chief improvement in boat making, from the time of the Phœnicians until the first trip of the Clermont, was to do away with oars and to use sails only.

It was not until about fifty years before the time of Columbus that oars were generally discarded and large boats were propelled entirely by sails. Sailboats were, to be sure, a great improvement over oar boats. Yet at best they were slow and unreliable, held back alike by calm and storm. The Pilgrims were ten weeks in crossing the Atlantic, and the regular trip, in the time of Washington, required six weeks.

COLUMBUS'S SANTA MARIA.

Boats were thus from the very earliest times important in trade and travel. For this reason it is not surprising that Watt's engine was scarcely perfected, before men tried to make it propel a boat.

The First Steamboats

The first American to attempt the propelling of a boat by steam was William Henry, a gunsmith of Lancaster, Pennsylvania. In 1760, Mr. Henry was in England on business. He took great interest in the talk going on then about the use of steam to drive machinery, propel boats, and the like. On his return to America, he built an engine fashioned after one of Newcomen's engines, and so placed it in a boat that it worked a number of paddles. The boat did not go well, and a little later was accidentally sunk. Though unsuccessful, Henry never lost his interest in steamboats.

The first American to propel a boat by steam successfully was John Fitch. Fitch was a frequent visitor at the home of Henry, and probably got the idea of building a steamboat from him. However that may be, Fitch built a better boat than Henry, and he is regarded by some people as the real inventor of the steamboat.

TRIAL TRIP OF FITCH'S STEAMBOAT.

Fitch built his first boat in 1787. The engine was made in America, but was copied from that of Watt. Along each side of the boat stood two sets of three paddles. To move the boat, these were given a motion like the stroke in paddling a canoe. Six paddles entered the water, while six came out. Fitch had great difficulty in obtaining the money to build the boat, and even after it was built the boiler had to be made larger. Finally, after much delay and anxiety, all was ready for a public trial. This took place at Philadelphia. Men like Washington, Jefferson, and Franklin came to see the new wonder. It was marvelous to see a boat propelled by steam, but the speed was only three or four miles an hour, so there was no great enthusiasm over the steam oar boat.

The next year, Fitch built a second boat, with the paddles placed at the stern. But the boat could not be made to go faster than a man could walk, and it was no more of a success than the first. Fitch succeeded, however, in 1790, in making a boat sixty feet long and eight feet wide with paddles at the stern, which had a speed of seven miles an hour. After a trial at Philadelphia, it made regular trips, during the rest of the summer, between Philadelphia and Trenton running between two and three thousand miles with no serious accident. But it cost more to run the boat than the fares amounted to, and the venture failed.

Fitch found his way to New York, and might have been seen there in 1796, working on a screw steamboat. He had long since spent all his own money. Nobody would help him, and therefore the screw steamboat had to be given up. Completely discouraged, Fitch retired to a farm in Kentucky. He believed in the steamboat until the last, and was confident that the day would come when steamboats would be running on all our large rivers and across the ocean. "The day will come," said he, "when some more powerful man will get fame and riches from my invention; but now no one will believe that poor John Fitch can do anything worthy of attention."

Driving along the shore of the Delaware one day, John Stevens of New Jersey saw Fitch's little steamboat puffing slowly along between Philadelphia and Trenton. He followed it to the next landing and examined it with care. He had long been interested in steamboats and now decided to build one. He set to work with great energy, and by his enthusiasm he induced Robert R. Livingston of New York to share in the enterprise. After almost ten years of planning and experimenting, these men thought they were on the point of success. The boat of which they expected so much was launched in 1798. But alas! it could run only three miles an hour in still water, and was soon given up as a failure.

Stevens, undaunted, continued his experiments year after year. Model after model was made. Some of these boats had paddle wheels extending from the sides; some were propelled by a single revolving screw at the stern, and others had two screws. Stevens experimented also with different kinds of boilers. So successful was he that he came very near winning the prize that was afterwards awarded to Robert Fulton. The very next month after Fulton's first boat made its trial trip, Stevens launched the Phoenix, which was quite as good a boat as the Clermont. His screw propeller, as well as his boilers, afterwards came to be used extensively on ocean steamships. Thus, after Fulton, Stevens did more than any other man to make the steamboat a practical success.

Inventors in England were likewise busy. The most successful of these was William Symington. The money to build the trial boat was supplied by Lord Dundas, who hoped that steam might take the place of horses in towing canal barges. The Charlotte Dundas, Symington's boat, was ready for trial in 1802. She was a stern-wheeler, that is, she was propelled by a paddle wheel at the stern. An engine built by Boulton and Watt supplied the power. The new boat took two barges of seventy tons burden each, and in the face of a strong wind towed them down the canal twenty miles in six hours.

Lord Dundas was delighted. He wanted this way of towing adopted. The other owners of the canal were not convinced, however, that there would be much saved by the change, and besides, they feared that the new boat would damage the banks of the canal. Lord Dundas finally succeeded in interesting the Duke of Bridgewater, who gave Symington an order for eight boats like the Charlotte Dundas. Had these been built, Symington would to-day probably be known as the inventor of the steamboat. Unfortunately the Duke died about this time, and the boats were never built. The Charlotte Dundas  was anchored in a side creek to rot, and Symington gave up the project in despair.

Though men had been working and experimenting for many years, a practical steamboat, that is, one which could be used at a good profit to its owners, was yet to be built. There was great need of such a steamboat, and Watt's engine was strong enough to propel it. But no one seemed able to build a boat of the right shape, to make the right kind of a propeller, or to harness Watt's engine to it in the right way. So many attempts had been made, and there had been so many failures, that most men came to believe it was impossible to make a successful steamboat. The man who first succeeded in accomplishing the "impossible" was Robert Fulton.

Fulton's Early Life

Robert Fulton was born at Little Britain, Lancaster County, Pennsylvania, in 1765. His father, though not successful in money matters, was highly respected; he was a leader in the Presbyterian Church, and held a number of minor public offices of honor. His mother was an excellent woman who had more education than most women of the time, for she taught Robert reading, writing, and ciphering, until he was eight years of age.

ROBERT FULTON.

Robert was then sent to school, where he acquired a good elementary education. He was not a superior scholar. Books interested him much less than painting or the shop of the gunsmith. Nobody knows who taught him to paint, unless it was Major André, who was later hanged as a spy. Major André lived for some months at Lancaster and gave painting lessons there. It is possible that Robert was one of his pupils. At all events, the boy learned, when quite young, to draw and to paint.

He had some talent, and perhaps was inspired to become an artist by the example of Benjamin West, one of America's greatest painters. Mr. West when a boy was often in Lancaster, and he painted a portrait of Robert's father and mother. Mr. Henry, of whom mention has already been made, had a number of Mr. West's pictures, and Robert used to go to his home to look at them. It may be true, also, that Mr. Henry talked to Robert, when on these visits, about his steamboat, and how fine it would be to invent one, and that these talks did much to lead him to give up art and become an engineer and inventor.

Besides being fond of drawing and painting, Robert was fond of tools. Not far from his home, there were shops where muskets were made for the soldiers of the Revolutionary War. Robert was a frequent visitor there, and he spent much time in making drawings of guns and tinkering with broken muskets.

His turn for making things showed itself early. One day, Robert was very late at school. "Robert, why are you so late?" asked the teacher.

"I was making a pencil out of a piece of lead," he replied.

FULTON AND THE LEAD PENCIL.

The teacher looked at the pencil and found it a good one. Before many days, all the children had lead pencils.

At the age of seventeen, Fulton left Lancaster and went to Philadelphia. He gave his attention principally to painting portraits and miniatures, but he turned his hand to anything that came along. He drew plans for machinery and for carriages, and even houses. In this way he not only made his own living, but by the time he was twenty-one he had saved four hundred dollars.

While living in Philadelphia, Fulton became acquainted with Benjamin Franklin. Knowing that Fulton would never succeed as an artist unless he prepared himself better, Franklin advised him to go to London and study. Fulton decided to do this; but just then his father died, leaving his mother without a home. He therefore took a part of the four hundred dollars which he had planned to spend on his art education, and bought his mother a farm, where she lived in contentment and plenty for many years.

Studying Art in London

With a letter from Franklin to Benjamin West, Fulton set out for London, where he landed early in 1787. He had about two hundred dollars in his pocket, not a large sum with which to get an education; but lack of money has never been a bar to young men of character and energy. Benjamin West received the young man with kindness, and in addition to giving him instruction, helped him in other ways.

The story of Fulton's life at that time is told in a letter to his mother. "I had an art to learn by which I was to earn my bread, but little to support me while I was doing it. Many, many a silent, solitary hour have I spent in most anxious study, pondering how to make funds to support me until the fruits of my labor should be sufficient. . . . Thus I went on for nearly four years—happily beloved by all who knew me, or I had long before now been crushed by poverty's cold wind and freezing rain. When last summer I was invited by Lord Courtney down to his country seat to paint a picture of him, . . . His Lordship was so much pleased that he introduced me to all his friends. And it is but just now that I am beginning to get a little money and pay some debts which I was obliged to contract. So I hope in about six months to be clear with the world, or in other words out of debt, and then start fair to make all I can."

Engineer and Inventor

After four years of study, Fulton felt that he was ready to take up his life work. Among the friends to whom Lord Courtney introduced him was the Duke of Bridgewater, who became one of Fulton's good friends. Whether it was the talks about steamboats and about canals with the Duke of Bridgewater; or whether Fulton was carried away by what was then being written in England and America in regard to boats and waterways; or whether it was his talent for mechanics and invention grown strong, we do not know,—but Fulton suddenly gave up the idea of being an artist and decided to become an engineer.

Whether Fulton would have become a great artist or not, no one can tell. He surely had artistic ability. He had been taught by the best teachers of England, and had gained some recognition and honor as an artist. At all events, if the world lost a great artist, it gained a great inventor. Nor was his training as an artist entirely lost when he turned engineer. He was able to make his ideas clear by means of drawings, and was also able to draw his own plans and designs.

Immediately after making his decision, Fulton went to Birmingham, where he lived for two years. There he studied the great canals which were being built. He became acquainted with Watt and his engines, and saw the best mechanics in Europe at work. His active mind soon began to turn out invention after invention. He invented a double inclined plane for raising and lowering canal boats from one level to the other, a machine for spinning hemp, and one for twisting hemp rope.

A project to which he gave a great deal of time was his submarine or plunging boat. Fulton was able to go down into the water in this diving boat twenty feet or more, and move about. In this way he could get near a vessel without being seen, and then by means of a cigar-shaped torpedo which he invented could blow it up. In an experiment at Brest, in 1805, he succeeded in doing this. Fulton thought his diving boat and torpedoes would make war vessels useless, and would do away with war on the seas. He tried in turn to get the French and English governments to adopt this invention; he also offered it to the United States. Nothing, however, came of his efforts. Submarine and torpedo boats have since come into general use, but they have not put an end to naval war, as Fulton hoped they would.

Experimenting with Steamboats

We do not know when Fulton first began to think of making a steamboat. But we have his own words for saying that in 1802 he began "experiments with a view to discover the principles on which boats or vessels should be propelled through the water by the power of steam engines." Fulton did not undertake to make a successful steamboat without knowing of the failures of Fitch, Stevens, Symington, and others; and without understanding that after so many failures, men who still thought a practical steamboat could be built were looked upon as madmen. Yet it has ever been so. The men who win fame and fortune do what other people say cannot be done. Fulton learned all he could from the mistakes and failures of others. To make sure that he was right before he went ahead, he did what was still more important, he made experiment after experiment.

He built a model boat, four feet long and twelve inches wide, provided with two strong clock springs for power. Experiments were made with propellers which opened and shut like a duck's foot, with side paddle wheels, stern paddle wheels, side oars, screws, and paddles fastened to an endless chain passing over two wheels. Fulton was convinced that side paddle wheels were the best. He learned also that the propelling surface of the different paddles combined should be twice the exposed surface of the bow. In addition, he worked out a table to show the power that was needed to move boats of different sizes at different speeds. With this information, Fulton was ready to experiment on a larger scale, and he began to dream of boats that should make the trip between New York and Albany in twelve hours.

Robert R. Livingston was at this time United States minister to France. Fulton, then living in France, succeeded in getting him to advance the money to make the larger experiment, and the two formed an agreement that if the experiment proved successful, they would construct and run steamboats between New York and Albany. To protect themselves in their invention, Livingston secured from the State of New York, in the name of himself and Fulton, the exclusive right for twenty years to navigate steamboats on all waters of the state. No one thought, even in 1803, that there was any danger that such an invention would be a success.

Fulton at length set to work on a boat seventy feet long, eight feet wide, and with three feet draft. The paddle wheels were twelve feet in diameter, and the engine was about eight horse power. When the boat was nearly ready for the trial trip, a violent storm arose one night, and so beat the boat about that it broke in two and sank to the bottom of the Seine. Fulton was awakened from an anxious sleep by the shouts of his servant, who exclaimed, "Oh sir! the boat has broken to pieces and has gone to the bottom."

Fulton hurried to the river, to find that this was all too true. He labored for twenty-four hours without stopping, to raise the boat. The machinery was little harmed, but the hull was such a wreck that it had to be entirely rebuilt. This occupied several months, and the boat was not again ready for trial until August, 1803.

FULTON SHOWING HIS BOAT TO LIVINGSTON, IN PARIS.

The trial trip was thus described in one of the French newspapers: "At six o'clock in the evening, aided by only three persons, he (Fulton) put his boat in motion . . . and for an hour and a half he produced the curious spectacle of a boat moved by wheels, . . . these wheels being provided with paddles or flat plates, and moved by a fire engine. In following it along the wharf, the speed against the current of the Seine was about that of a rapid walker, that is about four miles an hour. . . . It was maneuvered with ease, turning to the right and left, came to anchor and started again." Not only was the new boat declared a success by the French newspapers, but the success was such as to lead Livingston and Fulton to begin the building of a boat for actual service on the Hudson.

Building the Clermont

A twenty-four horse power engine was ordered, in August, 1803, from Boulton and Watt, to be shipped to New York. Boulton and Watt at first refused the order, because the British government would not let them ship the engine. The government probably feared that the engine was to be used in a torpedo boat by the French. After much delay, permission was secured, and the order was accepted. Fulton, who was then in England, went to Birmingham to see that the engine was built just as he wanted it; for he was right in feeling that the success of his boat depended upon how the engine worked. Fulton arrived at New York in December, 1806. He at once hired a famous shipbuilder, whose yards were on the East River, to build the hull of the boat. The boat was to be one hundred and fifty feet long, thirteen feet wide, and was to draw two feet of water.

When it became known that the new boat was to be a steamboat, idle crowds used to collect around, and in derision they called it "Fulton's Folly." Nor did these crowds take kindly to the idea of a steamboat; they even went so far as to try to destroy it. Neither did the owners of the sailboats on the East River like the idea, so when they were passing by in their sloops they would bump into the Clermont. To protect the boat, it became necessary for Fulton to hire men to watch her both by day and by night.

No one had any faith in the success of the venture. When, in 1806, Livingston and Fulton offered to take Stevens into partnership with them, he refused, and said, "Mr. Fulton's plan can never succeed."

At another time, when it became necessary to raise a thousand dollars to complete the Clermont, Fulton went to some of his friends for aid. Most of them told him they were too wise to sink good money in such a wild scheme. After much difficulty, however, Fulton succeeded in obtaining the needed money, but only by promising his friends to keep their names secret. They feared that they would be ridiculed for their folly.

The Clermont, when completed, was a queer-looking craft. There was a mast at each end, but these carried very small sails. A little to the front of the center stood the smokestack and the working beam and piston. Projecting from the center over each side was a great uncovered paddle wheel. "She looked," said one observer, "like a backwoods sawmill mounted on a scow and set on fire."

FIRST TRIP OF THE CLERMONT.

First Trip of the Clermont

The Clermont was ready for her first trip up the Hudson, August 17, 1807. Here is Fulton's own story of the trip:

"The moment arrived at which the word was to be given for the boat to move. My friends were in groups on the deck. There was anxiety mixed with fear among them. They were silent, sad, and weary. I read in their looks nothing but disaster, and almost repented of my efforts. The signal was given, and the boat moved on a short distance and then stopped. . . . To the silence of the preceding moment, now succeeded murmurs of discontent and agitation, and whispers, and shrugs. I could hear distinctly repeated, 'I told you it was so; it is a foolish scheme; I wish we were well out of it.' "

"I elevated myself on a platform; I stated I knew not what the matter was, but if they would be quiet and give me half an hour, I would either go on or abandon the voyage for that time. . . . I went below and found. . . . the cause. . . . In a short time it was fixed. The boat was again put in motion. She continued to move on. All were still incredulous. None seemed willing to trust the evidence of their own senses. We left the fair city of New York; we passed through the romantic and ever varying scenery of the Highlands; we descried the clustering houses of Albany; we reached its shores,—and then, even then, when all seemed achieved, I was the victim of disappointment. . . .

"It was then doubted if it could be done again, or if done, it was doubted if it could be made of any great value."

In another letter Fulton wrote:

"My steamboat voyage to Albany and back has turned out rather more favorably than I had calculated. The distance from New York to Albany is one hundred and fifty miles. I ran it up in thirty-two hours and down in thirty. I had a light breeze against me the whole way, both going and coming, and the voyage has been performed wholly by the power of the steam engine. I overtook many sloops and schooners beating to the windward, and parted with them as if they had been at anchor.

"The power of propelling boats by steam is now fully proved. The morning I left New York there were not perhaps thirty people in the city, who believed that the boat would ever move one mile an hour, or be of the least utility, and while we were putting off from the wharf, I heard a number of sarcastic remarks. . . .

"Having employed much time, money, and zeal in accomplishing this work, it gives me, as it will you, great pleasure to see it fully answers my expectations. It will give a cheap and quick conveyance to the merchandise on the Mississippi, Missouri, and other great rivers, which are now laying open their treasures to our countrymen; and although the prospect of personal gain has been some inducement to me, yet I feel  . . . more pleasure in reflecting on the immense advantage that my country will derive from the invention."

WATCHING THE CLERMONT STEAM UP THE HUDSON RIVER.

The passage of the Clermont  caused great excitement among the people along the way. Here is a description written by one who stood on the bank and saw the boat go by:

"It was in the early autumn of the year 1807, that a knot of villagers was gathered on a high bluff just opposite Poughkeepsie, on the west bank of the Hudson, attracted by the appearance of a strange, dark-looking craft which was slowly making its way up the river. Some imagined it to be a sea monster, whilst others did not hesitate to express their belief that it was a sign of the approaching judgment. . . . The dense clouds of smoke, as they rose, wave upon wave, added still more to the wonderment of the rustics.

"On her return trip, the curiosity she excited was scarcely less intense,—the whole country talked of nothing but the sea monster, belching forth fire and smoke. The fishermen became terrified and rowed homeward, and they saw nothing but destruction devastating their fishing grounds; whilst the wreaths of black vapor and rushing noise of the paddle wheels, foaming with the stirred-up waters, produced great excitement amongst the boatmen."

On her return from Albany, the Clermont was put in dock. The paddle wheels were covered, decks were made over the boilers, the rudder was repaired, and three cabins of twelve berths each were fitted up to accommodate forty to fifty passengers. Thus equipped, the Clermont started in September, 1807, to make regular trips between Albany and New York, and continued to do so until the Hudson froze over late in November. As a passenger packet, she was a success from the first. To be sure, people were in great fear that the boiler would burst, or that the boat would catch on fire. There was also a vague feeling that something terrible must surely happen to the "monster which defied storm and tide and belched forth fire and smoke."

The fare was just the same as that on the sailboats, three dollars, but it took sailboats, on the average, forty-eight hours to make the trip, and the average time of the Clermont  was only thirty-six hours. It was not long before she was crowded.

Steamboats on River and Ocean

Most great inventions are a long time in coming, but when once their utility is demonstrated they are quickly adopted. This was true of the steamboat. During the winter of 1807 the Clermont  was made better and larger, and renamed the North River. So great was the demand, that within the next eight years Fulton constructed, or there were built according to his plans, no less than ten other boats for service on the Hudson River, Long Island Sound, and the Potomac. Fulton also designed and built great steam ferryboats to cross the East River and the Hudson River. Steven's Phoenix  began in 1807 to make regular trips on the Delaware, and by 1810 steamboats could be seen trailing long lines of smoke up and down the Mississippi and the Ohio. They were also introduced into England and Russia, and even into far-away India.

AN OLD FERRYBOAT TICKET.

Fulton's belief in the commercial usefulness of steamboats was so great that he not only expected them to be placed on all the rivers of the civilized world, but he hoped to see them on the great oceans also.

The first steam vessel to cross the Atlantic Ocean was the Savannah, in 1819. Fulton did not live to witness this great event, for he died in 1815. To a great idea,—steam navigation,—he had given freely of his time, his talents, and his money. Others like Fitch helped him to succeed. Others like Stevens improved on his invention. Together they gave to the world one of its chief means of travel, transportation, and communication. Yet to Robert Fulton belongs the honor of being the first inventor to make a genuinely successful steamboat.

FULTON'S ESTIMATE FOR A STEAM FERRYBOAT.

George Stephenson And The Invention Of The Locomotive

With Watt's steam engine to pump out the water and to hoist the coal, miners were going deeper into the earth, and were bringing out more coal than ever before. The "new giant" turned countless mills for grinding corn and wheat, and was harnessed to the machines lately invented for spinning and weaving cotton and wool. The day of cheap fuel, cheap food, and cheap clothing seemed at hand. One thing was lacking, a cheap means of carrying over land, fuel, wheat, cotton, wool, and the like, to the mill or factory; and of carrying the finished product to the market. There was great need of a locomotive which would do good work at a small cost. Men began to work on such a locomotive. They did not, of course, try to invent a new engine, but to modify Watt's engine, a stationary engine, so that it would be a serviceable moving engine. George Stephenson succeeded in doing this.

GEORGE STEPHENSON.

His Parents and Home

About eight miles west of Newcastle, England, is the mining village of Wylam. Near the east end of the town there stands a two-storied house of four rooms. The lower west room was once the home of the Stephenson family. The floor of this single room, which served alike for kitchen, dining room, parlor, and sleeping room, was of clay. The walls were unplastered, and the rafters were bare. Here, on June 9, 1781, George Stephenson was born.

The father was the fireman of the Newcomen engine at the Wylam mine. With a wage of not more than a dollar and a half a week, and with six children in the family, there was scarcely enough for food and little to spare for clothing. So poor was the family, that none of the children were sent to school. But George received from his father and mother traits of character which were even better than riches, and made amends for his lack of early education. It was a trait of his to have definite ambitions. He set his hopes on an advance of one step at a time. When the desired position was secured, he was not satisfied, but prepared himself for a further advance.

Upward Step by Step

As soon as George was old enough, he was put to work. His first job was herding cows, at four cents a day.

Growing older and stronger, he was hired out to do light farm work. He drove horses, milked cows, and hoed in the garden. But he soon joined his brother James at the mine, as a "picker" to clean the coal of dirt and stones. His wages were now twelve cents a day, and they were increased to sixteen cents when he became driver of the gin horse.

Driving a gin horse was well enough, but George wanted to be an engineer. To be assistant fireman was the first step. Great was his joy when, at about fourteen, he was made assistant to his father, at the wage of twenty-five cents a day.

By the time he was fifteen George had become a fireman, and was still ambitious to be an engineer. He spent the greater part of his spare time in studying his engine and in learning how each part worked. It was a great event in his life when some two years later his wages were raised to three dollars a week. "I am now," he was heard to remark, "a made man for life."

Not long after this, a new mine was opened, and George became the engineer. It was his duty to run the engine, keep it in order, and look after the pumps. If for any reason the engine stopped, and he was unable to make it go, he was to call upon the chief engineer of the mine. But the youth knew every part of his engine so well that he never needed to call for help.

Modeling engines in clay was his main pastime. He made models of those which he had seen, and of others which were described to him. In this way he first heard of the engines of Boulton and Watt. Wanting to know more about them, he was told that he would find them described in books. Alas! George could not read,—he did not even know his letters. He thus found that to advance further, he must be able to get information from books. Although he was as large as a grown man, and was doing a man's work, he decided that he must go to night school.

He went to school three nights a week, taking lessons in reading, spelling, and writing. During one or two winters, he took lessons also in arithmetic. This was easy for him. The secret was his perseverance. He spent his spare time about the mine on his "sums." The problems solved during the day, he carried to his teacher in the evening, and received new "sums" for the following day.

STEPHENSON MODELING AN ENGINE IN CLAY.

About this time, he decided to learn braking. A brakeman operates the machinery which hoists the coal. The work is responsible and well paid. A good friend allowed George to try his hand at the work, and although only twenty years of age, he was soon braking at another mine.

Thus, through attention to work and study, and through perseverance, George Stephenson advanced step by step from herdboy to brakeman; he educated himself, and became a skilled worker.

Further Improvement

To add to his wages, Stephenson took to mending and making shoes in the evening. Among the shoes sent to him was a pair belonging to the girl who became his wife, a young woman of sweet temper, kind disposition, and good common sense.

Happy in his work, and content in his home, Stephenson set about improving the spare hours of the evening more diligently than ever. He studied mechanics, and came to know thoroughly the engines of both Newcomen and Watt. He took also to modeling machines. One of these was a perpetual-motion machine. Though it proved a failure, as all others have, it gave him opportunity to whet his powers of invention.

Shortly after the death of his wife in 1806, Stephenson went to Scotland, to superintend, in a cotton factory, a Boulton and Watt engine. This gave him the chance he had long wanted, to work with one of those wonderful machines. He remained there a year, returning with more than a hundred dollars saved from his wages.

In the meantime his father had met with an accident. While he was inside of a Newcomen engine, a workman turned on the steam. The blast struck him full in the face, not only scalding him terribly, but putting out his eyes. The poor man struggled along against poverty as best he could. On the son's return, his first step was to pay his father's debts, and a little later he moved his parents to Killingworth, where they lived for many years, supported entirely by him.

An Engine Doctor

For some unknown reason, the engine at the High Pit, a coal mine near Killingworth, failed to work, and the miners were driven out by the water. The engineers of the neighborhood were called in, but each in turn failed to discover the trouble. One day Stephenson wandered over to the mine and examined the engine carefully. "Well, George," asked a miner, "what do you make o' her? Do you think you could do anything to improve her?"

"I could alter her," he replied, "and make her draw. In a week's time I could send you back to the bottom."

This conversation was reported to the manager, who in despair decided to give Stephenson a chance.

"George," said the manager, "they tell me that you think you can put the engine at High Pit to rights."

"Yes, sir, I think I could."

"If that's the case, I'll give you a fair trial . . . . The engineers hereabouts are all beat; and if you succeed in doing what they cannot do, you may depend upon it, I will make you a man for life."

The engine was taken to pieces, and many changes were made. These were completed in about three days, and the engine put to pumping. By ten o'clock that night the water was lower in the pit than it had been for a long time, and by the end of the week the workmen were "sent back to the bottom." Stephenson had made good his words.

His skill as an engine doctor was noised abroad. He was called upon to prescribe remedies for all the wheezy, creaky pumping engines of the neighborhood. As an engine doctor his wages were good, and he soon left the "regular" workmen behind. They in turn were jealous of him and looked upon him as a "quack." The manager of the High Pit, however, believed in him, and succeeded in 1812 in making him engine wright at Killingworth.

Educating his Son

Stephenson often thought of the difficulties he had in life because of his lack of schooling. He was determined to give his only son Robert, born in 1803, a good education. As soon as Robert was old enough he was sent to the parish school. The education to be had there scarcely went beyond the primer and writing, and it soon seemed best to send Robert to Newcastle. This was expensive, and Stephenson's earnings were small. Besides, he was the sole support of his afflicted parents. How was the money to be obtained? "I betook myself," said Stephenson long afterwards, "to mending my neighbors' clocks and watches at night, after my daily labor was done, and thus I procured the means of educating my son."

Robert went to and from Newcastle on a donkey. But it was not only Robert who was at school at Newcastle, his father was also at school there. Their evenings were spent together in going over the lessons of the next day. Books were brought from the library to be read. When the desired books could not be taken out, Robert would bring home descriptions and sketches for his father's information. The son thus helped to educate the father—but such a father! Do you wonder that Robert was later proud of saying that if his success had been great, it was mainly to the example and training of his father that he owed it?

GEORGE STEPHENSON AND HIS SON ROBERT STUDYING TOGETHER.

The First Railroads and Locomotives

Stephenson as engine wright at Killingworth not only had to keep the pumping and hoisting engines in repair, but it was also part of his duty to look after all the other machinery. As he traveled from mine to mine, he was on the lookout to find where improvements could be made. Among other improvements, he began to think about a locomotive.

The locomotive was still looked upon as a curious and expensive toy. Stephenson saw more clearly than most others of what great use it might be, not only in carrying coal to market, but in transporting all kinds of products. He turned all his knowledge of machinery, and all the power of his inventive mind, to the making of a locomotive.

There are three parts to a railroad: the locomotive, the cars, and the track on which these run. The first railways were tramways, used to haul coal from the mines to the wharves, where it was loaded on boats to be carried to distant cities. Such tramways were often ten to a dozen miles long. They were constructed by building a roadway more or less level, and by placing, upon wooden crossties, two wooden rails. At some mines, a thin plate of iron was nailed on the upper surface of the rails. Cast-iron rails, three or four feet long, were also common.

The cars had a large hopper-like, wooden body. This huge body rested on a wooden platform made of heavy wooden beams. These were fastened at each end to an iron axle, which connected the two supporting cast-iron wheels. A horse could draw, at the rate of two or three miles an hour, two or more of these cars, when loaded altogether with from eight to ten tons of coal.

Two parts of a railroad, the rail or tramway and the cars, were thus at hand when Stephenson set himself to make a locomotive. His object was to invent an engine which would take the place of horses on the tramways. Hence, his locomotive to be successful must do the same work, not only more satisfactorily, but at less cost than it could be done by horses.

The idea of such a locomotive did not originate with Stephenson, nor was he the first to make one. That honor belongs to Richard Trevithick, who built a locomotive as early as 1804. This locomotive was able to haul ten tons, along with the cars, men, fuel, and the like, at the rate of five or six miles an hour. For a short time it was in successful use. But it broke so many of the small cast-iron rails of which the road was made, and ran off the track so often, that it was soon put aside and the engine degraded to working a pump. The trouble was with the track and not with the engine. With a little more perseverance, Trevithick might have succeeded in making a successful locomotive and have risen to fame and fortune. But Trevithick was a genius, fond of trying new projects. He left his locomotive, after a few trial trips, to take care of itself, and thought no more about it.

No one devoted much attention to the locomotive for some time. Still, the idea was not lost. In 1811, Mr. Blenkinsop, a mine manager near Leeds, decided to build one. Blenkinsop followed Trevithick's design. The big flywheel was, however, omitted, while the new features were the two cylinders and a toothed wheel working in a rack rail.

This toothed wheel and rack rail were contrived to overcome an imaginary difficulty. Even the wisest men of the time thought that if a load were placed behind an engine, the "grip" or "bite" of its smooth wheels on the smooth rails would be so slight that the wheels of the engine would spin round and round in the same place and the engine never move. Naturally, Blenkinsop thought that the toothed wheel working in a rack rail was necessary, if his engine was to draw a load.

Blenkinsop's locomotive, when loaded lightly, traveled at the rate of ten miles an hour. It would draw ninety tons at three and a half miles an hour on a dead level, or fifteen tons up grade. The locomotive cost two thousand dollars, and did the work of sixteen horses. For more than twenty years it was in constant use, and was the first successful locomotive ever made.

Encouraged by Blenkinsop's success, Mr. Blackett, of Wylam, resolved to try a locomotive at his mine. The first one made for him "flew all to pieces" on first trial. He had a second one built, which like the first was modeled after Trevithick's and Blenkinsop's engines. The new locomotive had a flywheel, and the driving wheel was cogged and traveled in a rack rail. This engine was able to haul eight or nine loaded cars at the rate of a mile an hour. It was too heavy for the track, and the rails were always breaking. The driver was asked one day how he got on. "Get on?" said he, "We don't get on; we only get off!"

PUFFING BILLY.

The chief cause of the failure was the cogged driving wheel working in the rack rail. Blackett learned by experiment that these were unnecessary. His third locomotive, built in 1813, was fitted with 61 smooth wheels. This new engine, Puffing Billy, was more of a success. It was easy to manage, and drew ten to fourteen loaded cars, having a combined weight of twenty tons, at the rate of four or five miles an hour.

Stephenson's First Locomotive

Stephenson's first engine, Blucher, was built in 1814. It was not much of a success. The best that Blucher  could do was to pull thirty tons on a grade, at the rate of four miles an hour. After a year's trial, it was found that it cost just as much to haul coal by steam power as by horse power. There was little encouragement in this, for the success of the locomotive depended on its economy.

Stephenson set to work with new vigor, and early in 1815 completed a second engine. This new engine had a wrought-iron boiler eight feet long and thirty-four inches through, with a single flue twenty inches in diameter. The flue was furnished with a steam blast. The steam blast or forced draft was one of Stephenson's wonderful inventions. In the earlier locomotives, the steam after doing its work in the cylinder was allowed to escape into the air, with a horrible hissing which terrified both man and beast. Stephenson noticed that the steam escaped with much greater speed from the cylinder than the smoke came from the smokestack. It occurred to him that if this escaping steam were turned into the smokestack, it would produce a draft. This, by increasing the intensity of the fire, would make it possible with the same size boiler to produce a greater amount of steam. The experiment was no sooner tried than the speed and the power of the engine were more than doubled. It is not too much to say that, without the forced draft, along with a boiler with a number of small tubes connecting the fire box and the smokestack, invented afterwards, locomotives might still be dragging along at a rate of not more than four or five miles an hour.

A Successful Locomotive

In Stephenson's first engine, the power was applied to the driving wheels by means of cogwheels. Stephenson saw that if the locomotive was to be a success, the power would have to be applied directly. In the new engine, the two cylinders were connected directly with the four driving wheels. To obtain the necessary freedom of motion, and to avoid the friction and jars due to rough places in the track, ball-and-socket joints were used to join the connecting rods with the crossheads of the cylinders, and with the crank pins of the driving wheels. Stephenson planned also to connect each pair of driving wheels by bars fastened to cranks in each axle. Workmen were, however, not able at this time to forge these cranks, and it was necessary, for the time being, to fall back on connecting chains.

Stephenson thus succeeded in making an engine having direct connection between the cylinders and the driving wheels, direct connection between all the wheels, and a forced draft. These are the essential points in all the engines which have been built since. Stephenson therefore accomplished for the locomotive, what Watt had done for the steam engine.

Building the First Steam Railroad

Although Stephenson's locomotives were in daily use at Killingworth, and had been for years, nobody paid any attention to them except a mine owner here and there. There seemed little prospect that the locomotive would come into general use. Stephenson, however, had a growing faith in his invention.

In 1821, Mr. Edward Pease obtained from Parliament authority to construct a tramway between Stockton and Darlington. Not many days later, a stranger called on Mr. Pease, describing himself as "only the engine wright at Killingworth." George Stephenson wished to be the engineer of the new road. Mr. Pease saw that he was the very man for the place.

When the Stockton and Darlington Railroad was planned, there was no thought of using locomotives on it. None of the directors had any faith in them. Stationary engines were to be put at the very steepest grades, but the bulk of the hauling was to be done by horses. Stephenson lost no chance to tell Mr. Pease of his locomotives. "One locomotive," said he, "is worth fifty horses. Come over to Killingworth and see what my engines can do; seeing is believing." Mr. Pease finally went to Killingworth and with him seeing was believing. Three of Stephenson's locomotives were ordered to be ready for the opening of the road.

As the time for opening the road came near, Stephenson became anxious. He was hopeful, however. At dinner with his son Robert one evening, he said: "I venture to tell you that I think you will live to see the day when railways will take the place of all other methods of conveyance in this country,—when mail coaches will go by railway, and railroads will become the great highways for the king and his subjects. The time is coming when it will be cheaper for a workman to travel upon a railway than to walk on foot. I know there are great difficulties to be faced; but what I have said will come to pass, as sure as you live. I only wish I may live to see the day, though I can scarcely hope for that, as I know how slow progress is, and with what difficulty I have been able to get the locomotive thus far adopted, notwithstanding my ten years' successful experiment at Killingworth."

The first of the three engines to be delivered was engine number one, Locomotion. These engines were built after Stephenson's latest plans, in his own factory at Newcastle. They did not differ much from the engines built eight or ten years before at Killingworth, but the workmanship was better.

STEVENSON ON THE ENGINE LOCOMOTION, AT THE OPENING OF THE STOCKTON AND DARLINGTON RAILROAD.

A great crowd gathered to see the new road opened. The locomotive was the center of attraction. Some came to rejoice, but many came to see the traveling engine blow up. A great procession was formed with engine number one at its head. Stephenson was the engineer. The train was made up of twelve cars loaded with coal and flour, a passenger coach for the directors and their friends, and twenty-one coal cars for other passengers, in all a train of thirty-four cars. At the head of the procession rode a man on a horse, carrying a banner with these words on it: "Private Risk is the Public's Gain."  At the signal, off started the great train. It moved at first at a rate of six to eight miles an hour. Stephenson finally decided to try the speed of the engine. He signaled the horseman to get out of the way, and put on the steam. The train now rushed toward Darlington at the rate of fifteen miles an hour, a marvelous speed for the day. The success of the engine excited great interest and admiration.

The number of passengers to be carried was a surprise. Not much had been thought of carrying passengers, and when the road was opened the company had only one passenger car, the Experiment. Other cars were soon added. The bodies of some old stagecoaches were bought and fastened to the wheels of coal cars. These passenger cars were first drawn by horses, but it was not long before one of Stephenson's locomotives could be seen steaming merrily along, drawing a train made up of a number of loaded coal cars and one or two of these grotesque passenger coaches.

Getting the Steam Railroad Accepted

The success of the Stockton and Darlington encouraged a group of men who contemplated building a railroad between Liverpool and Manchester. Some of them went to Killingworth to see Stephenson's engines. After seeing them, one of the men wrote: "Here is an engine that will before long effect a complete change in society. Mr. Stephenson is the greatest practical genius of the age, and if he develops the full powers of that engine his fame in the world will be equal to that of Watt." Naturally enough, when it was decided to build the new road, Stephenson was chosen engineer.

The new railroad stirred up much opposition, particularly among the owners of turnpikes and canals. The newspapers printed all sorts of ridiculous things. The railroad would keep the cows from grazing and the hens from laying. The poisonous smoke from the locomotives would kill the birds, the grass, and the trees. The sparks would burn all the houses along the way. There would no longer be any use for horses,—indeed, it would not be long before there would be no horses, and therefore oats and hay would be worthless. The price of land would be lowered, for it would be impossible to plow the neighboring fields, and dangerous to drive along the near-by wagon roads. Besides, any number of people would be killed by the bursting boilers. All these fears seem ridiculous to us, but they were very real then.

There was also great opposition in Parliament when the bill to construct the road was secured. People were not ready to believe that an engine could fly across the country, with hundreds of persons in its train, faster than the fleetest horse or dog could run. The very idea was absurd.

All sorts of amusing questions were asked: What would happen when the engine came to a curve in the track? How could an engine go in the face of a strong wind?

"Suppose now," said one member of Parliament, "that a cow got in the way of the engine; would not that be an awkward circumstance?"

"Yes," replied Stephenson, "very awkward for the cow."

Not only were Stephenson and his idea of a steam railroad ridiculed, but the best engineers of the day were called in to show that the road could not be built where Stephenson was going to build it. At one point the road passed over a great swamp, Chat Moss. "No engineer in his senses," said one of these experts, "would go through Chat Moss. Who but Mr. Stephenson would have thought of entering Chat Moss? It is ignorance . . . . Every part of the scheme shows that this man has applied himself to a subject of which he has no knowledge."

STEPHENSON SHOWING THE POSSIBILITIES OF THE LOCOMOTIVE.

Thus George Stephenson, "the engine wright of Killingworth," with only his practical knowledge to guide him and his genius to inspire him, battled for his ideas against the most learned men of the day. He stood alone. He was called "ignorant," "out of his senses," and "mad"; but as he said later, "I put up with every rebuff and went on with my plans, determined not to be put down."

When the Liverpool and Manchester road was nearly done, the directors were puzzled as to whether it was better to use stationary engines or locomotives. The engineers they consulted advised the use of a system of stationary engines placed at intervals along the way. Stephenson alone held out for the locomotive. With public opinion against him,—for the most frightful stories were told about how dangerous and terrible the locomotive was,—he urged his view upon the directors in and out of season. Even in his darkest hour, he declared: "Locomotive railroads will, before many years, be the great highways of the world." At length the directors decided to offer a prize of two thousand dollars for the best locomotive. Four were entered for the prize: the Novelty, the Sanspareil, the Rocket, and the Perseverance.

The Rocket was Stephenson's engine. It did not look much like the engines built at Killingworth or for the Stockton and Darlington, but the principles followed in making the Rocket were the same as in the earlier engines: few parts, and direct connection between the cylinders and the driving wheels. There was one important improvement. The earlier engines had a single large flue running through the boiler between the fire box and the smokestack. The Rocket was fitted with a boiler, in which there were twenty-five copper tubes, each three inches in diameter. This style of boiler, to be found now in all locomotives, made it easier to keep up the steam. The Rocket was therefore the best and fastest engine that Stephenson had built.

The trial was held at Rainhill, in 1829. Thousands of people, including many engineers and interested persons the world over, came to see the contest. The Novelty ran at the rate of twenty-four miles an hour, but it broke down. The Sanspareil  traveled at an average speed of fourteen miles an hour, but its pumps got out of order and it had to stop. The Perseverance  was unable to go more than four or five miles an hour, and was withdrawn from the contest. There yet remained the Rocket. On the Rocket, George Stephenson pinned all his hopes. He had battled for years for a great idea. He had done work and had faced difficulties which would have crushed many another man, but his courage had never failed him. Now, the Rocket  would show the world whether or not he was "ignorant," "out of his senses," and "mad," and whether or not the steam railroad would become the "great highway of the world."

The Rocket  made the trial trip at a maximum speed of twenty-nine miles an hour and at an average speed of fifteen. She met every condition of the contest. The spectators were greatly astonished at the wonderful performance.

THE ROCKET.

The Liverpool and Manchester Railroad was opened to the public in 1830. The event was justly looked upon as of national importance, and there was a big celebration. A great procession went from Liverpool to Manchester and back again. Thousands upon thousands of people gathered along the way to view the great sight, but few of those who on that day saw a locomotive for the first time, realized the importance of the invention made by the "engine wright of Killingworth."

In a very few years after that memorable contest at Rainhill, many counties saw the locomotives busy hauling raw materials to the mills and factories, busy carrying the manufactured products where they were needed, and busy in speeding passengers from place to place. The different sections of the same county were thus brought nearer together. Frontier regions were easily settled, new industries were developed, and new markets opened. The locomotive is therefore to be ranked as one of the world's great inventions, and George Stephenson as one of the world's great men.

Invention of the Electric Engine and Electric Locomotive

At the very time when Watt was working on his steam engine, Fulton on his steamboat, and Stephenson on his locomotive, men were beginning to learn about a new power which has since become almost as useful as steam. That power is electricity. Electric engines are now employed in mills and factories to drive all kinds of machinery, and electric locomotives are used on many railroads to draw great trains.

An electric engine includes two main parts: the dynamo, which produces or generates the electricity, and the motor, through which the electricity is converted into power. Before an electric engine could be constructed, it was necessary to discover a method of producing electricity in great quantities at small cost, or to invent the dynamo; and also to find a way to change, with small loss, electricity into power, or to invent the motor. Besides, a great deal had to be learned about electricity itself. The electric engine, like most inventions, is therefore not the work of one man, but of many men working at different times and in different countries.

The Electric Battery

Almost everybody knows a little about electricity. Very often on a cold day, if one rubs his feet on a carpet and then touches another person, a crackling sound will be heard, and the person touched will receive a shock. Something like this happens when a cat's back is rubbed briskly. Despite these and other interesting things that have long been known, not much interest was taken in electricity so that it was not until very recently that much was really understood about it. Men did not begin to study electricity with care until about two hundred years before Washington became President.

FRICTIONAL ELECTRIC MACHINE: A, THE GLASS DISK; P AND N, THE PRIME AND NEGATIVE CONDUCTORS.

Otto von Guericke, a German, was one of the first to study it carefully. He made the first machine to generate or produce electricity. His machine was merely a globe of sulphur supported so that he could turn it by a crank. When he placed his dry hand on the moving globe, it would attract bits of paper like a magnet. A similar machine was made later by placing a glass disk so that it could be easily turned, and by fixing a number of rubber or silk brushes so that they would rub against the revolving glass.

BATTERY: Z, ZINC PLATES; C, COPPER PLATES.

Alexander Volta, an Italian, was also a pioneer. He discovered in 1800 that two different metals in contact with each other would produce an electric current. From this discovery, he invented an electric battery. It consisted of a number of cups piled on top of each other. In each cup he placed a disk of copper and a disk of zinc, covered with a brine of common table salt. The copper disk of the first cup was connected by a copper wire with the zinc disk of the second cup, and so on. A copper wire was also fastened to the copper disk of the first cup and one to the zinc disk of the last cup. On taking hold of these last two connecting wires a strong electric shock was felt, and the current continued to flow regularly. A battery like Volta's can be made without the cups by using a glass jar. It should be remembered, however, that the strength of the battery does not depend upon the size, but upon the number of the disks or plates.

Volta's battery was the first easy way found to produce electricity in quantities. Years of study and experiment have shown also that the metals used by Volta, copper and zinc, are the very best to employ in batteries. The so-called "dry battery," for example, used to work doorbells, was made until lately of copper and zinc disks covered with sand or sawdust, soaked in acid and sealed. The battery is to-day the most common of electrical appliances. There are one or two in almost every home.

The Magnetic Magnet

Most boys at some time or other have owned a magnet, which, as you know, will pick up or attract bits of paper, pins, or even filings. To make a compass, stroke a needle from end to end with one end of a magnet, and float the needle on a bit of cork. Iron filings arrange themselves in file like live soldiers, if a magnet is placed under a sheet of paper and the filings are spilled over the paper. It is the invisible currents of magnetism flowing around the magnet that make the filings squirm about.

THE MAGNETIC MAGNET.

For many hundreds of years, bar and horseshoe magnets were made by rubbing small iron bars over a natural magnet or loadstone. Loadstones are pieces of hard, black rock found in Asia Minor, China, and Japan. They were thought to confer peculiar powers upon the persons possessing them. Such persons could win friendship, succeed in business, tell whether they were being married for love or for money, and were safe from many diseases. Naturally enough, magnets were looked upon as valuable possessions. Yet no practical use was made of them until about the middle of the twelfth century, when a wise sailor placed a magnetized needle upon a float, to learn which way was north. Magnets are now used for many purposes, and it was the study of them and their action that led to the invention of the dynamo, the telegraph, the telephone, and many other modern conveniences.

MARINER'S COMPASS.

The Electromagnet

Sailors long ago noticed that when there was constant lightning, the needle of a compass danced about in all sorts of ways. The same dancing about of the needle was observed when a magnet was brought near a compass. These and other facts, like knives being made into magnets when a house was struck by lightning, aroused curiosity among scientists, to find out what connection there was between magnetism and electricity.

In the winter of 1820, it occurred to Professor Oersted, of Copenhagen, to try a new way to find the answer. On a table before him lay a compass and beside it was one of Volta's batteries. He connected the wires to complete the circuit of the battery, and brought one wire close to the side of the compass parallel to the needle. The needle swung around, just as if he had a magnet in his hand. When the current was sent through the wire toward the north, the needle moved to the left. When the current was sent through the wire toward the south, the needle swung to the right. Oersted saw he had made a discovery. Passing an electric current through a wire makes a magnet of the wire. "Magnetism," he said, "is but electricity in motion." Oersted's discovery was of importance, for it led to the invention of the electromagnet, one of the most useful electrical inventions.

ELECTROMAGNET.

The first electromagnet was made by Sturgeon, an Englishman. He took a round bar of very soft iron and bent it in the shape of a horseshoe. Around this he wrapped a wire, and through the wire he passed an electric current. He varnished the core, as the iron bar is called, to keep the electricity from flowing off or away from it.

Sturgeon was surprised at the way the electromagnet worked. It was very much stronger than a natural or permanent magnet of the same size. But the most surprising element was that the instant the current was turned on, the iron core became a magnet, and when the current was turned off the core practically ceased to be a magnet. It might be thought that this peculiar action of the electromagnet would make it a useless plaything, but it is this very action which makes it so useful. If a needle or other object is picked up with a permanent magnet, the only way to get it off the magnet is to scrape or pull it off; but to get it off an electromagnet, it is necessary only to break the electric current. The electromagnet is thus under our control. To put it to work, we turn on the electric current; to make it stop working, we turn off the current. You do this every time you push the button of an electric doorbell.

ELECTRIC DOORBELL: G, GONG; E, ELECTROMAGNET; B, BATTERY; P, PUSH BUTTON.

We can control also the power of the electromagnet, that is, the size of the load it will lift. The man who taught us how to do this was Joseph Henry, an American. Instead of varnishing the iron core as Sturgeon had done, to keep the electricity from flowing off, or to insulate it, Henry insulated the copper wire by covering it with a wrapping of silk. Instead of putting a single turn of wire round the iron core, he put many turns. On his first electromagnet he put thirty-five feet of wire, making about four hundred turns. These additional turns increased the strength of the magnet very much.

Henry found that the magnet was stronger when wound with a number of separate coils of wire, the ends of each coil being connected with the battery. With a small battery, one of Henry's electromagnets lifted eighty-five pounds, and in 1831 he exhibited a magnet which lifted thirty-six hundred pounds. Thus by using a small or large battery, small or large iron cores, a few or many coils of wire, electromagnets of different strength can be made.

Henry was also the first to make the electromagnet do work at a distance, and to show us how it could be made useful. In telling of this he says: "I arranged around one of the upper rooms in the Albany Academy a wire more than a mile in length, through which I was enabled to make signals by sounding a bell." This first electric bell was made up of a permanent magnet about ten inches long, supported on a pivot, and placed with one end between the two poles of an electric magnet. When the current was passed through the electromagnet, this caused the bar magnet to swing and strike the bell.

Small electromagnets by the millions are now in use. In connection with the electric battery, they ring our doorbells, sound alarms, move signals, and the like.

Enormous lifting magnets are now employed to handle iron and steel. Some of these will lift as much as a hundred thousand pounds. Electromagnets are thus of themselves doing all kinds of work for us, and in addition they are, as we shall see, an essential part of the telegraph, the telephone, and the dynamo.

The First Dynamo

The discovery that an electric current would produce a magnet suggested to Michael Faraday, of the Royal Institution at London, the question, Will a magnet produce an electric current? He kept asking himself this question over and over again. Oersted had changed electricity into magnetism. Faraday set about doing the opposite, change magnetism into electricity. He first tried to do this in 1822, but failed. He also failed in three other attempts. In the year 1831 he took up the problem for the fifth time. He coiled 220 feet of wire around a pasteboard tube and connected the ends of the coil to an instrument which would show if there was an electric current flowing. Taking a round bar magnet eight and a half inches long and three fourths of an inch in diameter, he thrust it quickly full length into the coil. The needle of the instrument showed that there was a current, but the current stopped when the magnet came to rest. He jerked the magnet out, and again the needle moved, but in the opposite direction. The needle swung back and forth each time the magnet was thrust in and out, but there was no movement when the magnet was still.

Faraday at last, after five attempts, succeeded in producing an electric current from a magnet. He saw why he had failed before. In his earlier attempts, the coil of wire and the magnet were left at rest. A magnet might lie in or by a coil of wire for a hundred years, and no electric current would come from it. The electric current, as Faraday had learned, is produced by the magnet when in motion, or when the wire coil breaks through the currents of magnetism coming from the magnet.

Faraday now saw how to make a new machine to generate electricity. A copper disk twelve inches in diameter and a fifth of an inch thick was fastened on a brass axle. This was so mounted that the disk could be turned rapidly. A powerful permanent horseshoe magnet was placed so that the disk revolved between its two ends. A metal collector was held again the edge of the disk, and a second collector was fastened to the axle. Faraday turned the disk, and a steady current of electricity was produced. This was the first dynamo ever made.

By persevering until he found out how to produce an electric current from a magnet, Faraday blazed the way for some wonderful inventions. Without the dynamo to generate the electricity, we should not have electric lights, electric street cars, electric railroads, or electric-driven machines in factories.

Making the Dynamo Useful

There are two parts to every dynamo, the magnet and the whirling disk. The electricity is produced by the disk, called the armature, breaking through or across the currents of magnetism coming from the magnet.

The currents of magnetism in Faraday's dynamo were supplied by a permanent magnet. But the electromagnet supplies a more powerful magnetic field than the strongest permanent magnet; therefore in all the dynamos of to-day, electromagnets are employed. In the very largest dynamos there are a number of these, each more powerful than the strongest one made by Henry.

A MODERN DYNAMO.

The armature in Faraday's dynamo was merely a copper disk. Present-day armatures are made up of a core or inner portion, and the windings of copper wire over the core. The core in the common armature is made up of a great number of very thin and soft sheet-iron disks. Around these are wound many thousand turns of copper wire.

Between the time when Faraday made the first dynamo and the present, many men worked to make the dynamo useful, that is, to make one which would produce electricity in large quantities and at a small cost. Among these experimenters are to be counted Siemens of Germany, and Edison of America. Under the careful and patient work of these and other men, the simple dynamo of Faraday grew into the monsters of to-day. From these monster dynamos, hidden away in some remote power house, comes the electric current to light our homes and streets, to drive the machines of mills and factories, to propel street cars, to haul passenger trains, and even to cook our food.

Finding the Motor

What was now needed was a machine, a motor, that would convert electricity into power which could be used to turn all kinds of machines. Toy motors were made as early as 1826. But a practical motor, even if a good one had been invented, was not possible until the dynamo had been perfected, and cheap electricity was to be had.

In 1873 there was an Industrial Exhibition at Vienna, Austria, where a number of dynamos were displayed. One day an absent-minded workman connected the wires of a dynamo which was running, to one that was standing still. To his surprise the armature began to spin around. It was thus discovered by accident that the dynamo, invented to produce electricity, could be used also to change electricity into power, or that the dynamo is also a motor. Dynamos and motors are now built almost alike, but motors do not have to be as large and heavy as dynamos. It thus came about that the men who perfected the dynamo, at the same time, without knowing it, perfected the motor.

The Dynamo and Motor at Work

The motor was immediately put to work. At the Industrial Exposition at Berlin, in 1879, Dr. Siemens exhibited a small electric locomotive drawing a train of three small cars. The track, about a thousand feet long, was circular, and for this reason the first electric railway was called "Siemens's electrical merry-go-round." In 1881, Dr. Siemens built a street-car line a mile and a half long. A motor was fastened between the axles of an old horse car, and a dynamo exactly like the motor on the car was set up to furnish the electricity. The new electric line easily drove the omnibus from the street. Electric street railways were soon being operated in all parts of the civilized world, and no sight to-day is more familiar than the trolley car.

ELECTRIC TROLLEY CAR; P REPRESENTS TEH POWER.

Edison was quick to see the practical importance of the motor, and on hearing of Dr. Siemens's "electrical merry-go-round" set to work. His first electric locomotive was built early in 1880. It was made up of an ordinary flat dump car, on which was mounted a dynamo for a motor, known as "A Long-waisted Mary Ann." Improvements quickly followed, and it was not many months before his motors were ready to propel street cars. The first electric street railway in America was built at Baltimore, in 1885.

AN ELECTRIC LOCOMOTIVE.

Edison was also among the first to see that electric locomotives could be built large enough to draw freight and passenger trains, and by 1882 he had a big electric locomotive on exhibition at Menlo Park. Considerable use is now made of electric locomotives for hauling trains in and out of large cities, and on a few railroads they have taken the place of steam locomotives, either altogether or in part.

Besides being employed to propel trolley cars and locomotives, a great many motors are used in mills and factories to drive machinery. But it must not be supposed that all motors are large and powerful. They are of almost every imaginable size, from the great monsters in electric locomotives, down to the little motor that is just strong enough to run a sewing machine, or whirl an electric fan, or propel a toy engine.

The Invention of Spinning Machines: The Jenny, the Water Frame, and the Mule

While men were working on inventions to provide power to drive machines, and to furnish easy means of transportation and travel, others were working on inventions to be used on the farm, in the factory and the home, in the production and manufacture of articles of food, clothing, and shelter. The first of these inventions of manufacture and production were the spinning machines.

The Distaff and Spindle

The oldest spinning machine is the distaff and spindle. The spindle, the chief part of all machine spinning, is a slender round piece of wood or iron about twelve inches long, tapering toward each end. On the upper end, there is a notch or slit in which to fasten the thread. The distaff is a round stick, three or four feet long. One end is used to hold the loose supply of wool or cotton. The other end of the stick is held under the left arm, and is often fastened in a girdle at the belt.

When spinning with the distaff and spindle, the spinner pulls out from the loose wool or cotton on the distaff, a small piece, and twists the end of it by hand. This finished end is fastened into the notch or slit of the spindle. The spinner sets the spindle whirling, by rolling it between her right hand and leg, or by a twisting motion of the hand. Then the spindle is left to whirl as it dangles at her side. With her left hand she holds the loose thread, and with her right hand she draws it out to the proper size, as it is twisted by the whirling spindle. When a thread two or three feet long is thus properly twisted, the thread is unfastened from the upper end of the spindle and wound on the lower end. This process is continued until all the material on the distaff is spun.

SPINNING WITH THE DISTAFF.

Until about the time of the Revolutionary War, all the woolen, flax, and cotton yarn used in the world was spun thus. From such yarn were woven the clothes of peasant and prince alike. Even to-day, women may be seen in the Holy Land, spinning in this old-fashioned way.

The Spinning Wheel

The first improvement on this ancient method was the spinning wheel. This is a machine to whirl the spindle by turning a wheel. When the spinning wheel is employed, the cleaned wool or cotton is first carded, then twisted loosely, and finally spun into yarn. The carding is done with hand cards, big coarse nail brushes, about twelve inches long and five inches wide. The cotton is spread on one card and combed with another, until the fibers all lie in one direction. It is then taken off in fleecy rolls, about twelve inches long and three quarters of an inch thick. These short cardings are twisted on the spinning wheel, into a loose thread, or roving, about the size of a candlewick. The rovings are wound on reels or bobbins, and finally spun into the finished yarn.

CARDING WOOL BY HAND.

The spinning wheel was a big advance over the distaff. The spindle could be kept whirling more rapidly and easily. The hands were free to fasten the short cardings together and draw them into rovings, or free to draw out the roving and to hold it while being twisted into yarn. One spinner could now spin as much yarn as a half dozen had done before. The yarn was more even, and better twisted.

SPINNING WHEEL.

Spinning wheels were to be found in most homes until about 1840, and many are to be seen there now, preserved as curiosities. The mother always spun enough cotton and wool to supply the family with "linsey-woolsey" for clothes, and with yarns for socks.

James Hargreaves and the Spinning Jenny

The spinning wheel, which made only one thread at a time, was displaced by the spinning jenny, on which twenty, fifty, a hundred, and even a thousand threads can be spun at once. The inventor was James Hargreaves, an Englishman.

Hargreaves sat pondering one day over a faster way to spin cotton. His wife was busy in another part of the small room. Her spinning wheel for some cause toppled over. The spindle, which was thrown from a horizontal to an upright position, continued to whirl. Hargreaves saw, by one of those flashes of thought which come to the genius, that, if a number of spindles were placed upright side by side, and a way found to draw out the rovings as they were twisted, a number of threads could be spun by one pair of hands at one time. The idea of the spinning jenny was thus born. The invention was named jenny after Hargreaves' wife.

HARGREAVES DISCOVERS THE SPINNING JENNY.

One person can spin with a jenny as much yarn as twenty to a hundred can spin, using the old spinning wheel. The yarn, too, is of better quality. Besides, boys and girls between the ages of twelve and fourteen can operate it even better than grown persons. The invention of the jenny thus marks the beginning of child labor in cotton and woolen factories.

HARGREAVES' SPINNING JENNY.

The first jenny was completed about 1767. Hargreaves tried to keep his invention a secret, and to use it only in his own home. But he was tempted to make a few jennies to sell, to buy necessities for his children. In time, the spinners learned that he had a wonderful spinning machine with which a twelve-year-old girl could do as much work as a dozen grown persons with the spinning wheel. People at that time were not used to machines. It was the age of handwork, and they had not yet learned that machines in the end make more work and better wages. They only saw that this invention would lessen the number of spinners needed, and would deprive them of work. So the spinners, who as a rule were women, along with their husbands and friends, rose up against the inventor. A mob broke into his house and broke all the jennies that could be found, and Hargreaves had to flee for his life.

To protect his invention, he took out a patent in 1770, but this did no good. The spinning jenny was so easy to make that the manufacturers, quick to see its merits, made their own, and refused to pay any royalty on them. Thus it came about that Hargreaves received nothing for an invention which for forty years was the principal machine used in spinning cotton yarn, and still remains, as improved, the chief machine employed in spinning wool. He did not, however, live and die in poverty, as the story is often told. From a yarn factory of which he was part owner, he made a good living for himself and his family.

Richard Arkwright and the Water Frame

Cloth is made of two kinds of thread, the warp running lengthwise, and the woof running crosswise. Warp is a stronger thread than woof. Neither the spinning wheel nor the jenny made a cotton thread strong enough for warp. The warp in all cotton cloth up to this time was for this reason linen, and only the woof cotton. Linen thread costs more than cotton thread, and this made cotton cloth more expensive than if both the warp and woof were cotton. If cotton cloth was to be cheaper, a way had to be found to spin a cotton thread strong enough for warp. The man who succeeded was Richard Arkwright, also an Englishman.

ARKWRIGHT SELLING HAIR TO A WIGMAKER.

Richard Arkwright was the youngest of thirteen children in a poor family. If he ever went to school, it was only for a short time. To make up for his lack of early education, Arkwright, when more than fifty years old and when working from five o'clock in the morning until nine at night, took an hour each day to study English grammar, and another hour to improve his spelling and writing.

When a boy, he did all sorts of odd jobs, and finally became a barber. Even as a barber, he showed that he was a man of enterprise. The usual price for a shave was two pence. Arkwright made his price a penny. When the other barbers lowered their price to one penny, he advertised "a good shave for a half penny."

By the time he was thirty, Arkwright had enough of shaving. He took up buying and selling hair to be used in wigs, which were stylish at the time. He went about the country from cottage to cottage, and became an expert in getting young girls to part with their long, glossy locks. He also came into possession of a secret way of dyeing hair, which added to its value. As a dealer in hair, he gained a sort of reputation, for the wigmakers pronounced "Arkwright's hair the best in the country."

As a barber and as a dealer in hair, Arkwright had a good opportunity to talk with people about spinning, about the lack of yarn, and about the different spinning machines that were being invented. Whether he got the idea from one of his customers, or from other inventions, or whether he was wise enough to see the need himself, at all events, he made up his mind to invent a spinning machine. Like other inventors before and after him, he began to neglect his regular business. Instead of saving money, he spent more than he earned. So before the first successful model was completed, he had spent all his savings, and his family were in want.

Arkwright's machine, patented in 1769, spun cotton, flax, or wool. Pairs of rollers drew out the rovings, and flying spindles did the rest. The machine is called the water frame because it was first driven by water power, but a better name is the roll-drawing spinning machine.

ARKWRIGHT'S FIRST SPINNING FRAME.

His invention was even a greater one than Hargreaves'. The water frame spun such a strong thread that it could be used for warp. Cloth could now be made for the first time entirely of cotton, and it was not long before English calicoes made their appearance. The thread was also so strong that it could be used for knitting cotton socks. Hargreaves' spinning jenny was suited only to spin thread from rovings, while the rovings had to be twisted on the spinning wheel. But the water frame twisted the rovings as well as spun the finished yarn. The water frame thus did away with the spinning wheel in factories, but not with the spinning jenny. The spinning jenny continued to be used to make the softer threads for woof, while the water frame was employed to twist rovings and to spin the harder and stronger yarns.

ARKWRIGHT WATER FRAME.

Like Hargreaves, Arkwright received next to nothing for an invention which is busy to-day the world over, spinning the warp for the cloth used by millions of people.

But he did not stop with the water frame. He went on and on, making one invention after another, until he had a number of machines, best described by calling them a cotton-yarn factory. The uncleaned cotton was put into the first of these, and it came out of the last, the water frame, as snow-white, well-twisted thread.

Arkwright was not only a great inventor, but he proved to be a good business man. For a time, he made little from his inventions or from a cotton manufactory of which he was part owner. It was not long, however, before wealth began to flow his way. He finally became one of the most important cotton-mill owners in England, and for a number of years controlled the market price of cotton yarn. Shortly before his death he was made a knight.

Samuel Crompton and the Mule

The spinning jenny spun good woof. The water frame spun good warp. But neither of these inventions spun yarn fine enough to weave muslin. All the muslin of the day came from India. The Hindu spinners were so skillful that they could make the very finest yarn, even on the spinning wheel. The spinning machine which broke India's hold on the muslin trade was the mule, invented in 1779 by Samuel Crompton, another Englishman.

From early childhood Samuel helped his widowed mother, who supported her only son and her two daughters by keeping a cow or two, by having a good garden, and by spinning and weaving. Samuel's "little legs became accustomed to the loom almost as soon as they were long enough to touch the treadles." Yet he went to school regularly, and was given a good education. Going to school did not, however, relieve him from a certain amount of spinning and weaving each day. His mother was in her way loving and kind, but woe unto Samuel if his daily amount of spinning and weaving was not done.

HAND LOOM.

Whether or not the eight-spindle jenny used by Samuel was a poor one, much of his time was taken up in "mending the ever-breaking ends of his miserable yarn." To escape the reproach of his exacting mother, it kept him forever busy to do the allotted stint of spinning and weaving. Then, too, Samuel was an excellent workman. It may be that he longed to weave cloth as beautiful and delicate as the muslins of India. At any rate, by the time he was twenty-one years of age, he began to think how a better spinning machine than the jenny could be made.

Most inventors are inspired by the hope that from their inventions they will gain both fame and wealth. From childhood, Crompton had been much alone. Spinning and weaving was not then, as now, done in big factories. He knew very little about the world, and less about how valuable a great invention might be.

CROMPTON'S MULE.

Crompton worked on the new machine from the time he was twenty-one until he was twenty-six. He says: "The next five years had this . . . added to my labor as a weaver . . . , a continuous endeavor to make a more perfect spinning machine. Though often baffled, I as often renewed the attempt, and at length succeeded to my utmost desire, at the expense of every shilling I had in the world." It might be added, at the expense also of the good will of his neighbors.

Strange sounds were heard coming from Crompton's home. Lights were seen at all hours of the night. The rumor went about that the house was haunted. It was soon discovered that Crompton was the ghost. But when relieved of their fears of a ghost, the neighbors found that they had in their midst a "conjuror," the term of contempt applied to an inventor. So Crompton became an object of suspicion.

Hardly was the first mule completed, when the anti-machine riots of 1779 broke out. Mobs of spinners and weavers went about crying, "Men, not machines." Rioters went everywhere, destroying all the jennies and water frames they could lay their hands on, especially all jennies having more than twenty spindles. The usual number was eighty. Crompton knew that his invention would arouse the rioters even more than the jenny or the water frame. Fearing that they would destroy it, he took it to pieces and hid it in the garret of his workroom. There it lay for weeks, before he had courage to bring it down and put it together. He now learned for the first time what his machine would do. After a little practice, he could spin yarn on it fine enough for the most delicate muslin.

His invention is called the mule, because it combines in one machine the best points in Arkwright's water frame and the best points in Hargreaves' spinning jenny. Before this, the greatest length of yarn ever spun from a pound of cotton was less than 70,000 yards. With the mule, it was possible to spin, from a single pound of cotton, a thread 300,000 yards in length.

Crompton's only idea in inventing the mule, as stated before, was to make a machine for his own use. The way before him now seemed clear, and he married. For a few months he prospered, and he and his wife were happy. But such a valuable invention could not be kept a secret long. Crompton's yarn was the finest that came to the market, and he received the highest price for it.

His neighbors began to ask, "How can Sam Crompton make such fine yarn? He must have a new kind of spinning machine." Some of them went to his home to see. Crompton, of course, tried to keep them from learning about his invention. He wanted to be let alone, so that he might reap the fruits of his labor. He even went so far as to put a special lock on his workroom, and to put screens at the windows. But his neighbors were not to be outdone. They called at unexpected times. They even brought ladders and looked over the screens. One fellow, it is said, lay in the loft overhead for days, and peeped down through a knot hole.

This spying almost drove Crompton mad. He even thought of breaking his invention to pieces. "A few months reduced me," he afterwards wrote, "to the cruel necessity either of destroying my machine altogether or of giving it up to the public. It was not in my power to keep it and work it. To destroy it, I could not think of that; to give up that for which I had labored so long was cruel. I had no patent nor the means of purchasing one. In preference to destroying it, I gave it to the public."

To induce him to do this, some manufacturers promised to raise a liberal purse. The total subscription amounted to only about three hundred and thirty dollars, but no sooner was the invention made public than the subscriptions stopped. Worse still, some of the subscribers refused to pay what they had promised. Crompton scarcely received enough to make him a new mule, for he had given up to the manufacturers the one he was working with, to be used by them as a model in making others.

The first mule was a crude affair, and had not more than twenty or thirty spindles. Mules of to-day are among our most beautifully constructed machines, and some of them carry a thousand spindles. The mule, like the jenny, was first worked by a spinner, but to-day they are self-acting, that is, they work themselves. The mule as thus improved is the most wonderful of all spinning machines, and is used the world over, to spin both the warp and the woof of all the finer kinds of cotton goods, and the woof of the coarser cotton cloth.

Crompton did not go wholly unrewarded, however. In part payment for the benefits of his invention, Parliament voted him twenty-five thousand dollars. But this was soon wasted by his sons in business. A few years before his death he almost came to want. Some admiring friends then raised by private subscription a fund which gave him an annual income of three hundred dollars. Without this, he would probably have died in poverty.

Eli Whitney and the Invention of the Cotton Gin

With the inventions of Hargreaves, Arkwright, and Crompton, any amount of cheap cotton yarn could be spun. Soon, too, the power loom was invented, which lowered the cost of weaving. The age of cheap clothing seemed at hand, when the poor as well as the rich could afford clothes enough to be well dressed, clean, and warm. One difficulty stood in the way, the lack of cheap cotton.

The chief sources of cotton at that time were Asia and the West Indies. Very little cotton was raised in the United States, because of the great cost of separating the seeds from the fiber or lint. Ten to fifteen days' work would produce on one acre from five to eight hundred pounds of green seed cotton. But it was a long and tedious day's work to pick the seeds out of four pounds of seed cotton, so as to prepare a single pound for the market. The seeds were picked out by hand. This was usually done in the evening, after the regular work of the day. Then the slaves, father, mother, and children, would sit in a circle about a torch and pick.

An American, Eli Whitney, invented a machine to do this work. By reason of his invention, the United States is to-day the greatest cotton-producing country in the world. The cotton crop of 1916 amounted to more than sixteen million bales and was worth several hundred million dollars.

PICKING COTTON SEED BY HAND.

Whitney's cotton gin easily ranks in importance with the jenny of Hargreaves, the water frame of Arkwright, and the mule of Crompton. These four inventions are the foundation of the cotton industry of to-day. To spin and weave cotton, hamlets have grown into cities, such as Manchester in England, and Lowell in Massachusetts. Great territories, such as our Southern States, have been given over to the cultivation of cotton. Steamship and railroad lines have been built to carry cotton from the fields to the mills; and millions of people earn their daily bread from raising, or spinning, or weaving cotton, or from selling the finished goods. To have had a part in the growth of such a great industry is no slight honor.

Boyish Traits of Whitney

Eli Whitney was born at Westboro, Massachusetts, in 1765. His parents lived on a farm, and belonged to that sturdy class who provide well for their children, and train them to be industrious, saving, honest, and honorable,—virtues which boys and girls must have, if they are to lead clean lives, be useful, and be truly successful.

BIRTHPLACE OF ELI WHITNEY.

As a mere boy, Eli had a passion for pulling things to pieces, to see how they were made and how they worked. His sister tells this story: "His father's watch was the greatest piece of mechanism Eli had as yet seen. He was very anxious to look inside of it and to examine the works, but was not permitted to do so. One Sunday morning, observing that his father was going to meeting, and was leaving at home the wonderful little machine, he . . . made believe that he was sick, as an apology for not going to church. As soon as the family were out of sight, he flew to the room where the watch hung, and taking it down, he was so delighted with . . . the movements of the wheels, that he took it to pieces before he thought what he was doing. His father was a stern parent, and he . . . would have been punished for his idle curiosity, had the mischief been found out. He put the works all so neatly together, however, that his father never discovered . . . what he had done, until Eli told him many years afterwards."

WHITNEY AND THE WATCH.

Eli was equally fond of making things. "Our father," writes the sister, "had a workshop . . . and a variety of tools, also a lathe. This gave my brother an opportunity . . . to learn the use of tools when very young. . . . He was always making something in the shop, and seemed not to like working on the farm. On a time, after the death of our mother, when our father had been absent from home two or three days, on his return he inquired of the housekeeper what the boys had been doing. She told him what B. and J. had been about. 'But what has Eli been doing?' said he. She replied, 'He has been making fiddles.' 'Ah! I fear Eli will have to take his portion in fiddles!' "

Eli was not more than fifteen or sixteen years of age when he began to put his gift for making things to practical use. It was the time of the Revolutionary War. Nails, made then by hand, were scarce and brought a good price. Eli proposed to his father that he give him the needed tools to make nails. This the father did, and it was not long before Eli was supplying all the neighbors for miles around. Besides, he put new blades in broken knives, and did different kinds of curious jobs in a way which exceeded the skill of the country smiths. When the war closed, it was no longer profitable to make nails, but fashion came to young Whitney's rescue. The ladies of the time used long pins to fasten on their bonnets. Whitney made these pins with such skill and finish that he had a monopoly of the trade. He also built up a good business in walking canes.

When about nineteen, Whitney began to wish for a better education than could be obtained in the district school. By working in his shop, and by teaching school for two winters, he saved enough money to make a start. He entered Yale University in the fall of 1789. When a boy like Whitney enters college, now, he is almost certain to take a course in mechanical engineering. But when Whitney went to Yale, there was no such course. There was only one course, the classical, made up for the most part of Greek, Latin, and mathematics, with a little science. Though Whitney had no opportunity at Yale to prepare himself to become an engineer, he never lost his interest in making things.

One day a teacher found a piece of apparatus out of order, and said in Whitney's presence, "I am sorry, but it must go abroad for repair, to the shop it came from."

Whitney replied, "I think I might mend it."

Within a week the machine was as good as new.

Visit to the South

About the only opening for a college graduate in 1792, when Whitney finished his studies at Yale, was to become a minister, a lawyer, or a teacher. Few college graduates thought then of going into business, and there was little or no engineering work. Whitney decided, at least for a time, to take up teaching, so he secured a place to tutor the children of a wealthy gentleman at Savannah, Georgia. On the same boat for Savannah, was Mrs. Nathanael Greene, widow of the famous General Greene. Mrs. Greene saw that Whitney was a young man of character, and the two became well acquainted before they reached Georgia.

When Whitney arrived at Savannah, he found that his employer, instead of being willing to pay one hundred dollars a year and board, for the teaching of his children, as he had promised to do, was now unwilling to pay more than fifty dollars a year. Whitney refused to take the position. This left him in a strange city, without friends and almost without money. Mrs. Greene, on hearing of his troubles, invited him to her plantation, some twelve miles from Savannah.

Whitney was not long in winning the hearts of Mrs. Greene's children. His skillful fingers made for them many wonderful toys, and he repaired others that were broken. Nor did Mrs. Greene's respect for Whitney grow less as she came to know him better. She soon learned also that she was entertaining an inventor of the first rank. One evening, while making a piece of embroidery on a frame called a tambour, she complained that the frame tore the delicate silk threads of her work. An evening or two later, Whitney presented her with a frame to do the same work, but made in a different way. The new frame was much better than the old one, and Mrs. Greene wanted to know where he had obtained it. To her surprise, he replied, "Oh! I just got it out of my head."

WHITNEY REPAIRING THE CHILDREN'S TOYS.

Early in January, 1793, three former comrades of General Greene's visited Mrs. Greene. Being planters, they talked of farming and about what could and what could not be raised at a profit. They all agreed that much of their upland would raise good cotton, but that there was no profit in growing cotton, because it cost so much to separate the seeds from the lint. They deplored greatly the lack of a machine to do away with this tedious and costly work, whereupon Mrs. Greene said, "Gentlemen, why don't you apply to my young friend Mr. Whitney; he can make anything."

Whitney was called in, but when he learned what the planters wanted, he assured them that he did not know how to make such a machine. Still, to have the need pointed out to him, and to be asked to make a machine, aroused all of the inventive genius there was in him.

Inventing the Cotton Gin

The very next day saw him on his way to Savannah to get some cotton in the seed. Returning, he told Mr. Miller, who was at that time manager of Mrs. Greene's plantation, and afterwards her husband, what he intended to do. Mrs. Greene also became a party to the secret. They were scarcely less enthusiastic than Whitney himself. A room in the basement of the house served for a shop. Here they set up a workbench and assembled a few common tools. This done, Whitney set to work.

In Asia, the West Indies, and along the coast in the South, a crude kind of roller gin was in use, made of two rollers, which revolved very close together. The seed cotton put in on one side was drawn between the revolving rollers, as clothes are drawn through a clothes wringer. The seeds too large to go between the rollers were broken off, and dropped down on the opposite side from the cotton. This roller gin answered fairly well for the black seed cotton of Asia and the West Indies, and what little was raised along the coast in the South, as it has a long fiber, and large seeds loosely attached. With a roller gin one man could clean from fifty to sixty pounds of black seed cotton in a day.

But the roller gin would not clean the green seed cotton raised on the uplands of Georgia, which has a short fiber and small seeds firmly attached. Whitney however, obtained a valuable suggestion from the roller gin. He thought it would be a good idea to make a machine which would shove or thrust the cotton through slits so narrow that when the cotton was thrust through, the seeds would be torn off, just as they were broken off when the cotton was drawn between the rollers of the roller gin. How could such a machine be made?

Whitney's first successful gin had a hopper to hold the cotton. Iron bars placed close together in pairs formed one side of the hopper, and heavy boards the other. Reaching well up into the hopper was a wooden cylinder, armed with rows of wire teeth curved slightly back from the direction in which the cylinder moved. When the cylinder turned, the short wire teeth grabbed small bunches of cotton, and thrust these through the slits between the iron bars. The pressure of the cotton on the sides of the slits pulled off the seeds, which dropped into a trough, while the cotton fiber was drawn on through the slits. Most of the fiber fell from the wire teeth. What still held on was pushed off by big brushes on the left of the machine, which revolved in an opposite direction and four times as fast as the cylinder.

Whitney did not make a machine like this at first. The hopper of iron gratings and boards was clear in his mind from the start. The part giving the most trouble was the teeth of the cylinder. His first idea was to use teeth like the teeth of a circular saw. But he had at hand no iron plates thin and strong enough to make such teeth. Fortunately, there arrived at this time, at Mrs. Greene's, a coil of heavy iron wire, brought to make a bird cage for the daughter. The sight of this wire suggested to Whitney making wire teeth. The wire was too large and had to be drawn smaller. This was slow work with Whitney's crude tools. But he was an expert. Had he not drawn thousands of bonnet pins? Trial after trial was made with wire teeth of different lengths and shapes. He finally learned that teeth about an inch long, and curved slightly back from the direction in which the cylinder turned, were the best, and would take out all the seeds and not greatly injure the fiber. But every little while the teeth would become clogged, and it was hard work to get the cotton off. Mrs. Greene one day saw Whitney working away, cleaning the clogged teeth.

"Why don't you clean the cotton off this way?" and she began to brush away with a hearth brush.

"Just the thing!" exclaimed Whitney. Forthwith, a revolving brush was set up just back of the toothed cylinder.

Towards the end of the winter of 1793, Whitney completed his first machine. It was hardly finished before Mrs. Greene invited a number of friends in to see it work. With Whitney's little gin, scarcely harder to turn by hand than a grindstone, one man could clean as much cotton as fifty men cleaned in the old way.

The planters looked on in amazement, and were quick to see that, with this machine to take out the seeds, they could raise cotton at a good profit. They congratulated Whitney on his ingenuity. They urged him to get a patent at once, telling him that his invention was sure to bring him wealth and honor. Whitney was too much of a Yankee to be averse either to wealth or to honor. He and Mr. Miller entered into a partnership to take out a patent, and to make and sell gins. Mr. Miller was to supply the money.

So enthusiastic were the planters over the outlook for raising cotton, that it was hard for them to keep such a secret to themselves. Before long the news was all over Georgia. Crowds gathered from all parts of the state. The machine had not yet been patented, and Mr. Miller would not let them see it. One night, the shed in which it was kept was broken open and the machine carried away. It thus came about that gins were made after Whitney's ideas before he secured his patent.

Seeking the Reward

Miller and Whitney, as the firm was called, made a mistake often made by young men. They wanted to make a lot of money, and they wanted to make it quickly. Instead of asking a modest sum for the use of a gin and letting anyone make one who wanted to, they proposed to build and own all the gins that were to be used. For ginning the cotton, they proposed to take from the planters each third pound of cotton cleaned. This was an exorbitant charge. The very best cotton planters resented such a price and were angry at what they called a monopoly.

AN OLD-TIME COTTON GIN.

The gins built for use at this time had a rule eighty rows of teeth, and were worked by two horses or oxen, or by water power. With such a gin, one man could clean five thousand pounds of seed cotton, or prepare from a thousand to twelve hundred pounds of clean cotton for the market in a day, which is as much as a thousand men could clean by hand. Is it any wonder that these two young men had visions of great and immediate wealth?

From the first, Miller and Whitney found it difficult to obtain the money they needed to build a factory and to procure tools and materials. To build gins in large numbers also proved a bigger undertaking than either of the partners had supposed, for in the days when the cotton gin was young, there were few skilled mechanics, and there were no self-acting lathes, or planes, or drills. Everything was done by hand.

Then, too, the young men had bad luck. The factory which they built at New Haven, Connecticut, was hardly in good working order before it caught fire, and building, machinery, and finished gins were destroyed. Though steps were taken at once to build a new factory, this accident lessened the number of gins they were able to make. As late as 1796, they had only thirty gins of their own at work in the whole state of Georgia.

In the meantime, the production of cotton in the South increased by leaps and bounds. In 1792, the year before the invention of the cotton gin, there were raised and sent out of the United States 138,000 pounds of cotton. In 1793, about 487,000 pounds were exported; in 1794, about 1,000,000; and in 1800, about 17,000,000 pounds.

The planters put in cotton, expecting to take the seeds out of it with one of Whitney's gins. Even if the planters had been willing to pay one pound out of each three for ginning,—and there were many who were not,—Miller and Whitney had not and could not possibly have built gins enough to clean the entire cotton crop. What were the planters to do? Were they to let their cotton stand in the field and spoil, because there was no gin owned and made by Miller and Whitney at hand to clean it? Were they to stop raising cotton, because two young men had a patent on a great invention, and had a foolish idea about how to make a fortune out of it? The planters did what it was natural to expect them to do. They had some near-by carpenter and blacksmith make them a gin, and with it they cleaned their cotton.

Seeing what the planters were doing, Miller and Whitney gave up the idea of making and owning all the gins used. They now tried to collect a royalty of two hundred dollars a year on each gin in operation. A tax of two hundred dollars a year on a machine which a local carpenter and blacksmith can make at a cost of from fifty to one hundred dollars, and which had cost the inventor but three months of effort, was excessive. A few planters paid the fee, but most of them refused. An agent sent out through Georgia to collect these royalties was not able to get money enough even to pay his expenses.

Miller and Whitney had other troubles quite as serious as trying to collect royalties from planters. Hodgen Homes, of Georgia, patented a gin, called the "saw gin." It was made like Whitney's, except that dull teeth like the teeth of a circular saw were used instead of wire teeth. Homes's "saw gin" took out the seeds better than Whitney's, and did less injury to the cotton. Naturally, people preferred it to Whitney's, and it was on the point of driving his machine from the field.

Whitney's first idea, you will remember, was to use saw teeth. But iron plates thin and strong enough to make saw teeth were not to be had, so he fell back on wire teeth. Whitney therefore felt that Homes was using his idea, and he brought suit in court to prevent the making of "saw gins." Unfortunately for Whitney, in his application for a patent nothing was said either in words or in drawings about saw teeth. For this reason, it was hard for Whitney to prove that the idea of using saw teeth belonged to him and not to Homes. He finally succeeded and Homes's patent was taken away.

Finding it difficult to keep others from making and selling gins after their model, and being unable to collect a royalty from the planters, Miller and Whitney now thought it would be best to sell the right to use their gin to the states themselves. In this way they received altogether ninety thousand dollars. Much of this sum was spent for lawyers' fees and other expenses. What little remained made up in large part Whitney's reward for his invention, and for years of worry and disappointment.

If the cotton gin failed to bring to Whitney the wealth of which he dreamed, it did bring great wealth to the South. The invention came at a time when the old products of the South, such as tobacco and rice, were cheap, and when it was hard to find profitable use for her lands and for her slaves. The cotton gin created for her a new crop, "King Cotton," in which there were enormous profits. These profits made the South rich, adding millions of dollars to the value of her plantations.

Making Muskets

However, Whitney was destined to become rich. He was too gifted a man to be crushed by disappointment over his first invention. As soon as he saw that there was small chance of getting much of anything out of the cotton gin, he looked about for a field where he could use the genius he had for mechanics and invention, and where by industry and economy he might perhaps make the fortune which he once thought was all but in his hands. He began to make muskets for the government, and in 1798 he built a factory at New Haven, Connecticut.

Whitney's genius for invention showed itself no less in manufacturing muskets than in making the first cotton gin. Before his day, one man made the lock of a gun, another carved the stock, another drilled out the barrel, and so on. Each workman had considerable skill, did everything by hand, and made one entire piece. But no two locks, or stocks, or barrels were exactly alike. If the lock of a musket broke, no other lock would fit; a new lock had to be made for that particular gun.

FLINTLOCK GUN.

Whitney changed all this. He invented power machines to cut, to file, to drill, and to bore, which did away with hand machines. He divided the making of a musket into about a hundred different parts, and divided the making of each part into a number of single steps, so that little skill was needed by a workman to do any one of them. Each part was made after a pattern, so that all locks, all stocks, and all barrels were exactly alike. If part of a musket broke, it could be replaced at slight cost, by a new piece from the factory, which was sure to fit.

Whitney was the first to manufacture anything in this new way. His ideas were followed by others, and similar methods are now used in making all kinds of things. For this reason, Whitney is often called the "father of modern factory methods." He will always be honored, of course, as the inventor of the cotton gin, but his right to fame rests no less on what he taught the world about the use of machines in the making of common things.

Elias Howe and the Invention of the Sewing Machine

Sewing is older than spinning or weaving. Savages learned at an early time how to sew together pieces of fur. They used a pointed bone or a thorn to make a hole; through this they pushed a coarse thread or leather thong, making a knot at each hole.

It took thousands of years for sewing to get beyond the shoemaker's way of doing it. Women learned, to be sure, how to make different stitches, such as the plain seam and the hem. Fine spun thread took the place of coarse twist and the leather thong. The bone needle with an eye at one end and a point at the other gave way to delicate steel needles. Still, sewing continued to be done by hand, stitch after stitch, first one, then another, hour after hour. Even up to the days of our own grandmothers, the family sewing continued to be the burden of the home.

Men in England, France, and America worked for years to relieve the home of this drudgery. Machine after machine was invented, but each of these was a failure. Not until 1846, did an inventor succeed in doing for the sewing machine what Watt did for the steam engine, Stephenson for the locomotive, and Fulton for the steamboat. The inventor was Elias Howe, who was born at Spencer, Massachusetts, in 1819.

His Early Training

Howe's father was a farmer, who, in addition to his farm, had a gristmill, a sawmill, and a shingle machine. To the farm at Spencer, the neighbors brought their wheat and corn to be ground into flour and meal, and their logs to be sawed into lumber or split into shingles. Yet with all his labor, the income of the father was small, and supplied only a modest living to a family of eight children.

HOWE HELPING AT THE MILL.

In the pleasant surroundings of this New England farm, Elias Howe spent his childhood. Many were the rambles through the near-by woods for squirrels and nuts. The brook running through the farm afforded good swimming and fishing in the summer, and good skating in the winter. When he was old enough, the boy did all sorts of simple farm work, and helped at odd jobs about the mills and shingle machine. Each winter found him in the district school. Elias thus grew up, a happy, good-natured, play-loving boy. If his chances to obtain an education at the district school were not very good, this lack was made up, at least in part, by the opportunities he had to see and know trees, plants, and animals; and by being able to learn how to do things with his hands, and to become acquainted with tools.

Becomes a Mechanic

The father's first thought was to make Elias a farmer. At eleven years of age the boy was apprenticed, as was the custom of the day, to a neighbor, where he was to live and work until he was twenty-one. Elias was not strong, having a lame foot. This made farm work hard for him. After trying it for a year, he decided to give it up. Returning home he went to work in his father's mills, where he remained until he was sixteen.

About this time a friend of Elias's came back to Spencer from Lowell, Massachusetts. He told what a big and busy place Lowell was, and how Elias could get employment there and earn more money, and earn it more easily than at Spencer. Elias's ambition was thus stirred to go to Lowell and become a mechanic. It was not his liking for machinery that led him to go; it was the thought that a mechanic makes his living at easy work. Elias was not a lazy boy, but hard work so taxed his strength as to be very distressing to him. It was thus natural for him to want to avoid physical labor. His physical weakness led him also to do much thinking about how to do things with the least possible labor.

At Lowell, Elias was taken on as a learner in a factory for making cotton machinery. Here he worked for two years, when the factory shut down. Drifting to Cambridge he found, after a few months, a place much to his liking, with Ari Davis, who kept a shop for making and repairing watches, clocks, surveying instruments, and the like. Besides, his head was full of ideas of great machines. To hear him talk, it seemed not at all difficult to make a profitable invention. Naturally almost every workman in his shop had the inventor's bee. Still, Ari Davis's shop was not a bad place for a young country boy to be in, and it was here that Elias Howe gained the suggestion which led to the invention of the first successful sewing machine.

One day in the year 1839, a man came to the shop who was working to perfect a knitting machine. He was at his wit's ends, and brought the model to Davis to see if he could help him.

Davis in his extravagant way said, "What are you bothering yourself with a knitting machine for? Why don't you make a sewing machine?"

"I wish I could," replied the caller, "but it can't be done."

"Oh, yes, it can," said Davis. "I can make a sewing machine myself."

"Well," said the other, "you do it, and you will have a fortune."

These remarks were taken by most of the workmen as idle boasts. Not so with Howe. He kept brooding over the idea of "inventing a sewing machine and making a fortune."

As the boy brooded, this resolution slowly took form in his mind: "I will invent that sewing machine and win that fortune."

The First Sewing Machine

To Howe, a country boy just turning twenty, the idea of a sewing machine was new, but the idea was not new to the world. As early as 1790, Thomas Saint, an Englishman, took out a patent on a machine for "quilting, stitching, and sewing, and for making shoes, and other articles. . . ."

THOMAS SAINT'S MACHINE OF 1790.

Saint's machine had some of the features of good sewing machines to-day. Notice the overhanging arm and the block-like plate on which to place the material to be sewed. The machine had an awl, to punch a hole in the goods. A needle, blunt and notched at the end, pushed a thread through the hole to form a loop on the under side of the material. Through this loop the needle, on next descending, passed a second loop to form a chain or crochet stitch. There was also a feed to move the goods along under the needle, a continuous thread, and stitch tighteners.

It is probable that by the time Saint finished his machine and secured his patent, he was too much discouraged to go on with it. It may be, too, that to make a living he had to take up other work, and before he got back to his invention, he became sick and died. Whatever the reason, for almost sixty years his machine lay unknown in the English patent office. The result was that scores of would-be inventors worked on sewing machines, only to miss the good points in his invention. When it was finally brought to light, people looked at Saint's machine with amazement, and wondered how so great an invention could have been so completely forgotten.

CHAIN STITCH.

The chain stitch made by Saint's machine has one drawback. When a break in the thread is followed by a slight pull, the chain stitch unravels. This does not occur with the lock stitch. The lock stitch is made by two threads. These are interlaced in the middle of the fabric sewn, so as to form a neat stitch on both sides of the fabric.

LOCK STITCH.

The first sewing machine to make a lock stitch was invented by Walter Hunt of New York, about 1832. His machine had a curved needle with an eye at the point. The needle pierced the goods, and at the moment when it started out, a loop was formed in the thread; at that very same instant, a shuttle carrying a second thread passed through the loop, making the lock stitch.

Hunt was a gifted inventor. But either he thought little of his sewing machine, or he had other inventions which he thought promised greater and quicker profits. At any rate, he did not take the trouble to patent his machine, and proceeded to sell the model to a blacksmith for one hundred dollars. Even the blacksmith, after he had bought and paid for the model, made no use of it. Some twenty years afterwards, when Howe's lock stitch machine became famous, this old discarded model was dug out of a rubbish heap, and application was entered for a patent. The patent was denied. Hunt, like Trevithick before him, just failed to win one of the big industrial prizes of the century.

Making His First Sewing Machine

It is often said that great inventions are a growth. This is true only when the would-be inventor makes use of what others before him have done. The idea of a sewing machine was not only new to Howe, but he did not know until many years afterwards that Saint, or Hunt, or any one of a score of others in England, France, and America had ever made a sewing machine. So far as Howe knew, he was the first one in all the world who set out to make such a machine. So instead of trying to improve on what others before him had done, he went to work and created a new kind of machine altogether. For this reason, Howe's first sewing machine cannot be called a growth.

When Howe first got the idea of inventing a sewing machine, he probably did a lot of thinking, during his leisure hours, about how such a machine could be made. But to take his regular turn at Ari Davis's shop called for all the strength he had. It was not long before he gave up active work on his invention, saying to himself, "Some day, I will invent a sewing machine." This became Howe's daydream.

But it was not to remain a daydream. In 1840 Howe married, and in time three children were born. His wages were only nine dollars a week. Nine dollars a week was all too little to house, feed, and clothe a family of five. Besides, Howe's work was so hard that he often came home too tired to eat. He would go to bed, longing to lie there "forever and forever." Moved to act by the pinch of poverty and by the desire to escape the distressing fatigue of labor, he began to think once more about the machine which he had heard four years before would bring to its inventor a fortune. Then it was, about 1843, that the inventor's mania seized him, and gave him neither rest nor peace until he had made a sewing machine.

For almost a year, Howe, working evenings, tried to make a machine which would imitate the motions of his wife's hands, when sewing, and make a stitch such as she made. Every attempt to do this failed. One evening in the autumn of 1844, Howe sat brooding over his last attempt when there flashed into his mind this question: "Could there be another stitch which would do just as well as the stitch made by hand?" This question set Howe on a new track. He was familiar with the chain or crochet stitch, from long watching his wife sew. From working in machine shops, he also knew about shuttles and looms.

HOWE WATCHING HIS WIFE SEW.

Soon he had an idea. It was short work to snap the point off of one of his wife's sewing needles and sharpen the head, thus making a needle with an eye at the point. With this he thrust the thread through two pieces of cloth to make a loop. With another needle he passed a second thread through the loop, and gently pulled the two threads to tighten the stitch. A half dozen lock stitches were thus quickly made. But would such stitches hold? Howe was so anxious he scarcely had courage to find out. On trying to pull the pieces of cloth apart, to his great relief he found that this new kind of stitch held even tighter than the common hand stitch.

It was easy enough to see how to make a machine to sew such stitches. But Howe had no money to buy the materials, and no money to support his family while making the model, which, if it was to be successful, must be made with as much care as a clock.

There lived at this time at Cambridge, an old friend and schoolmate of Howe's by the name of George Fisher, who had shortly before this time inherited a little money. Howe interested him in the invention. Fisher promised, for a half interest, to board Howe's family while he was making the machine, and to advance five hundred dollars for tools and materials. Fisher said afterwards: "I was the only one of his neighbors and friends . . . who had any confidence in the success of the invention. Howe was looked upon as very visionary in undertaking anything of the kind, and I was thought very foolish in assisting him."

All through the winter of 1845, Howe toiled. He had the machine he wanted to make so vividly in mind that he worked almost as if he had a model before him. By May the first machine was complete, and in July he did with it all the sewing on two suits of woolen clothes, one suit for himself and one for Mr. Fisher.

THE FIRST HOWE SEWING MACHINE.

Howe's model was a strange-looking sewing machine. Every part has been improved, and many new ones have been added, but every one of the millions of sewing machines made since, owes at least one essential part to this machine, built in 1845. The way it sews is simple enough. The curved needle, with an eye at the point, carries the thread through the cloth, and the loop of the needle thread is locked by a thread passed through this loop by the shuttle. The materials are hung on the pins of the baster plate, which carries the goods along in front of the needle. The baster plate was the weakest part of the machine. The seam that could be made without stopping was short, and only straight seams could be sewed.

Exhibiting the Machine

The model was no sooner complete than off Howe carried it to one of the clothing shops of Cambridge. He offered to sew any kind of garment brought to him. The incredulous tailors and seamstresses brought shirts, waists, skirts, and trousers, and were amazed to see the seams sewed perfectly, at the rate of two hundred and fifty stitches a minute, which is about seven times as fast as handwork. For two whole weeks, he sewed seams for all comers.

Finally he challenged five of the fastest seamstresses in the shop to a sewing contest. Ten seams of equal length were laid out. One seam was given to each of the five seamstresses and five seams to Howe. Howe was through first, and besides, the umpire of the contest, a tailor, said that the work done on the machine was the neatest and the strongest.

One might suppose that Howe would at once have been flooded with requests for machines. But not one tailor, nor a single individual customer came forward with an order.

Nor did Fisher and Howe have any better success at Washington, in the summer of 1846, where they went to take a model and secure a patent. While there, they exhibited the machine at a fair. They had an enjoyable time and heard "Ah's!" and "Oh's!" on all sides, but not one voice was heard by their anxious ears, asking to buy or even to rent a machine.

Fisher was now discouraged. The machine had been known to the public for more than a year, and not a single one had been sold. He had boarded Howe and his family for almost two years, besides advancing in all about two thousand dollars.

"I lost confidence," said Fisher, "in the machine's ever paying anything."

Offering the Machine to England

Howe was not to give up so easily. Borrowing money from his father, he sent his brother Amasa to England, to see what could be done there. The first man to buy one of Howe's machines was William Thomas, of London. Thomas had a large factory in which he made corsets, carpetbags, and shoes. Seeing the value of the machine for his business, he bought the one Amasa had with him, for twelve hundred and fifty dollars. This was a poor bargain, because it also included the right to use as many other machines as Thomas might need. Thomas was to get also an English patent on the invention, promising to pay the inventor a royalty of fifteen dollars on each machine sold in England. Thomas patented the invention, but later refused to pay the promised royalty. By his foresight, along with his dishonesty, Thomas probably made on his investment of twelve hundred and fifty dollars, a net profit of a million dollars.

Howe still saw no prospect of making anything in America, so when Thomas offered him fifteen dollars a week, if he would go to England and adapt his machine to corset making and the like, he accepted. He set sail early in 1847, going in the steerage and cooking his own food. A little later he sent for his wife and children. For some eight months Howe worked to adjust his machine to the needs of Thomas's business. During all this time, Thomas treated him with respect. But when the work was done, Thomas made it so unpleasant that Howe had to give up his position. This left him a stranger in London, without work, and with a sick wife and three children to care for.

He had little money, but he undertook to make a fourth machine, hoping against hope that he could sell it at a good price. From Charles Inglis, a coachmaker, Howe rented a small shop, and with such tools as he could borrow went to work. Long before the machine was finished, his money ran low. To reduce expenses, he moved his family from a three-room apartment to one room, and this in the poorest section of London. Fearful that he might not be able to get his family back to America, he decided to send them while he still had the money, trusting that he could follow when the machine was finished and sold.

"Before his wife left London," said Inglis, who proved a friend in time of need, "Howe had frequently borrowed money from me in sums of twenty-five dollars, and requested me to get him credit for provisions. On the evening of Mrs. Howe's departure, the night was very wet and stormy, and her health being delicate she was unable to walk to the ship. He had no money to pay cab hire, and he borrowed it from me. He repaid it by pawning some of his clothing." Alone and without money, Howe had scarcely enough to eat to keep him alive. "He has borrowed a quarter from me," says Inglis, "for the purpose of buying beans, which I saw him cook and eat in his own room."

The finished machine was worth at the very least two hundred and fifty dollars. But the only customer Howe could find was a workman, who offered him twenty-five dollars, providing he could have time in which to pay it. No one else wanting the machine at any price, Howe was obliged to accept this offer. The purchaser gave his note for twenty-five dollars, and Inglis succeeded in selling the note to another workman for twenty dollars. The small sum of twenty dollars was thus Howe's return for some four or five months of toil and humiliation. To pay his debts and secure passage home, he was compelled to pawn his precious first machine and his letters of patent. Even then he had so little money that, to save cartage, he borrowed a handcart and hauled his own baggage to the ship.

Howe landed at New York in April, 1849. Four years had come and gone since the completion of the first machine. The one lone fifty-cent piece in his pocket was the only visible reward for these years of anxiety and toil. Yet Howe was happy. He heard that there was plenty of work in New York, and within a few hours he had a position as a mechanic in a machine shop.

A few days after this, news came that his wife was dying of consumption. He had no money to make the trip to Cambridge, and could not go, until his father—ever loyal—sent him the needed ten dollars. Howe arrived at his wife's bedside just in time to see her alive. The only clothes he had were the working clothes he wore, and to appear at her funeral he borrowed a suit of his brother-in-law.

Under such trials and humiliations Howe aged rapidly, and he looked like a man who had been through a severe illness. But he was once more among friends. They did not think much of his invention, but they loved the man. His children were being cared for, and soon he was hard at work again, not on his machine, but as a mechanic at a regular wage.

Fighting for His Rights

If money was not to be made out of the sewing machine as a useful invention, there were persons who thought that money could be made out of it as a curiosity. On the streets of Ithaca, New York, in May, 1849, you might have seen this show bill:

A GREAT
CURIOSITY
THE
YANKEE SEWING MACHINE
IS NOW
EXHIBITING
AT THIS PLACE
FROM
8 A. M. TO 5 P. M.

People came in numbers to see the new wonder, and women carried home samples of sewing as souvenirs.

This advertising led a few persons to want machines. Mechanics, especially in Boston, began to make and sell them. But this was not all. Other inventors entered the field. Among these was Isaac M. Singer, who added a number of practical parts and who did most to bring the sewing machine before the public.

Singer's interest in the sewing machine was aroused in the summer of 1850, while on a business trip to Boston. In the shop of a Mr. Phelps he saw a crude machine patterned after Howe's model at Washington. Noting Singer's interest, Phelps remarked: "If the sewing machine could be made to do a greater variety of work, it would be a good thing." Howe's machine, you know, sewed only a straight seam.

LADIES OF ITHACA IN 1849, WATCHING THE SEWING MACHINE AT WORK.

During the evening, at his hotel, Singer worked out the drawings for a number of changes. The next morning he showed a rough sketch of the proposed machine to Phelps and to a Mr. Zieber. They were satisfied that it would work. But Singer had no money to make a machine. Zieber proposed to advance forty dollars for the purpose, and Phelps offered to make the model in his shop. Work on the model started that very day.

"I worked at it day and night," said Singer long afterwards, "sleeping but three or four hours out of the twenty-four, and eating generally but once a day, as I knew I must make it for the forty dollars, or not get it at all.

"The machine was completed in eleven days. At about nine o'clock in the evening we got the parts together, and tried it. It did not sew. The workmen, exhausted with almost unremitting work, pronounced it a failure, and left me, one by one.

SINGER WORKING AT HIS FIRST MACHINE.

"Zieber held the lamp, and I continued to try the machine, but anxiety and incessant work had made me nervous, and I could not get tight stitches. Sick at heart, at about midnight we started for our hotel. On the way, we sat down on a pile of boards, and Zieber mentioned that the loose loops of thread were on the upper side of the cloth. It flashed upon me that we had forgotten to adjust the tension on the needle thread. We went back, adjusted the tension, tried the machine, sewed five stitches perfectly, and the thread snapped. But that was enough."

Thus in the course of eleven days, Singer, working at white heat, made over Howe's machine and added new features. Among these are the overhanging arms, the spring foot near the needle, and the double-acting treadle. By 1851, he had his machine ready for the market.

If Mr. Singer was not a great inventor, he was skillful in making practical the ideas of others, and he was a great business man. He, more than anyone else, aroused the world to the value of the sewing machine. He did this through advertising. He used posters, pamphlets, almanacs, and newspapers, to tell of the worth of the new invention. Sewing machine shows were held in towns and cities; there were bands to attract the people, and skillful young ladies to exhibit the wonderful work of the new marvel. Sewing contests were arranged, and prizes were given to the speediest and best sewers. Local agents were employed, and these agents, with their wagons loaded with machines, went everywhere. No wonder that a man as modern in his methods as Singer made a fortune, and that he was the founder of the greatest sewing-machine company in the world to-day.

To return to Howe. As Howe worked away at a mechanic's wage, he learned that sewing machines were being exhibited in different parts of the country as curiosities, and that persons were making and selling them. He examined some of these, and found that they were either made after his model at Washington, or embodied the essential parts of his machine. But never a word was said about his being the inventor. To secure his rights, as well as the reward for his labor, nothing remained but to take the matter to the courts.

Howe had no means, but he succeeded in interesting a man of wealth, who bought Mr. Fisher's half interest in the patent, and also advanced money to prosecute the infringers. The new partner, however, did not want to lose any money on the venture. To protect himself against loss, he demanded a mortgage on the farm of Howe's father. The father, faithful to the end, consented. Suits in court, then as now, went forward slowly, and Howe had time for other things. We find him in New York in 1850, making and selling fourteen of his machines. A few of those who had also been making and selling machines, fearful of the consequences, secured licenses from Howe, and this added a little to his income.

But Howe was busy chiefly, during the years 1850-1854, with his different cases in the courts. Singer, the chief infringer, contested Howe's rights the hardest. To show that Howe was not the inventor of the sewing machine, the inventions of Saint, Hunt, and many others were brought into court. Finally, in 1854, a verdict was rendered which gave Howe the victory. The judge found Howe's patent valid, and declared: "There is no evidence . . . that leaves the shadow of a doubt, that, for all the benefits conferred on the public by the invention of the sewing machine, the public is indebted to Mr. Howe."

Reaping the Reward

In the meantime, the new partner had died. His heirs having no faith in the future of the sewing machine, sold their share to Howe at a low price. For the first time he was the sole owner of his invention. Fortune was at last on his side. The public began to appreciate the sewing machine and suddenly a great demand arose for them. Howe received a royalty on all of whatever kind made in the United States, no matter where they were sold. A perfect flood of gold soon poured in upon him. In a very few years his income leaped from three hundred dollars to two hundred thousand dollars a year. In all he received about two million dollars in royalties, or approximately a hundred thousand a year, for the twenty years of his life devoted to his invention.

In return for this he gave an invention, which, as it has improved, has lessened the work and added to the comfort of almost every home in the civilized world; for sewing machines are to-day found alike in the jungles of the Amazon, and on the heights of the Himalayas. His invention has given birth also to new industries, such as the making of ready-made clothing. So enormous has this business become that single factories using hundreds of power machines, and employing thousands of women, turn out but one kind of article, such as frocks for girls or suits for boys. And it has given new life to more than half a hundred old trades, such as the making of straw hats, shoes, and harness. Even the manufacture and sale of sewing machines has in itself become a giant industry. If Howe's reward for his toil and anxiety was great, great also was his gift to the world.

Cyrus H. McCormick and the Invention of the Reaper

The chief occupation the world over is farming. This will always be true, because our food comes from the farm. The most important article of food is bread, and the best bread is made from wheat. The amount of wheat raised depends largely on the amount that can be harvested. The farmer, as a rule, has ample time to prepare the ground and sow the wheat, but the time within which he can harvest the golden grain is limited to from four to ten days. Very soon after the wheat is ripe, the stalks begin to break and fall down, and the grain begins to shatter. Unless cut very soon after it is ripe, the crop is lost. The harvesting wheat is, then, most important. Each improvement in methods of harvesting has increased the amount of wheat raised, and has decreased the amount of hunger in the world.

The Sickle and the Cradle

In the very earliest times, the harvester walked along and pulled the heads off by hand, leaving the stalks to stand in the field. The first improvement over this primitive method was the use of a long-bladed knife. By grasping a bunch of stalks with one hand, and using the knife with the other, a number of heads could be cut off at one stroke. A knife that was slightly curved answered better than one with a straight blade, and this led to the making of the sickle.

HARVESTING WITH THE SICKLE IN COLONIAL DAYS.

In the days when the sickle was king, the whole family turned out to help gather in the harvest. The women could reap quite as well as the men. It was a good day's work for one person to cut and bind into sheaves or bundles a half acre of wheat, which would yield anywhere from five to twenty bushels of grain.

The sickle gave way to the cradle, which first came into use about the time of the Revolutionary War. The cradle is merely a scythe furnished with wooden fingers running parallel with the blade. These wooden fingers hold the stalks of grain, after they have been cut off, in an upright position, and enable the cradler to lay the grain down in a neat row, with the stalks parallel, ready to be gathered into bunches and bound into sheaves.

HARVESTING WITH THE CRADLE.

A strong man could cut with a cradle from two to two and a half acres of wheat in a day, and a second man following along could gather it up and bind it into sheaves. The cradle was thus a great improvement over the sickle or reap hook, for it increased two to three times the amount of wheat one man could harvest. But cradling and binding grain was the very hardest work on the farm. In hot weather even the strongest men could keep at work only a part of the time. So long, then, as the cradle was the best means of harvesting, the amount of wheat that could be raised on a single farm was small. Still, the cradle continued to be the king of harvesters until almost the middle of the last century. Even to-day, wheat raised in stumpy ground, in small fields, and in orchards, is cut with a cradle.

The First Reaping Machines

The success of men like Watt with the steam engine, and Arkwright with the water frame, set many a man in England working on labor-saving machines. One of these, Patrick Bell of Scotland, came near making a practical reaper.

BELL'S REAPER AT WORK.

The important point to be noticed about Bell's reaper is the cutting apparatus. It is made up of twelve pairs of shears or scissors. One side of each pair of shears is fastened to the cutter bar and stands still; the other side is fastened on a pivot and vibrates back and forth, and thus cuts the grain. The reel draws the grain against the blades of the scissors, and causes it to fall, when cut, upon a moving canvas. The moving canvas carries the grain to one side, out of the way of the horses which are hitched behind the machine. In workmanship, this machine was far ahead of any reaper made in America until at least 1847. Bell's reaper was first tried in the harvest of 1828, and a public exhibition of its work was given in that year.

"This reaper," said a writer in 1852, "soon worked its way to a considerable success. . . . In the harvest of 1834 I saw several of them at work, all giving satisfaction. They were manufactured in Dundee, and thence found their way throughout the country. Four of them went to the United States of America. This renders it highly probable that they became the models from which the many so-called inventions of the American reapers have since sprung. . . . In a few cases the Bell reaper has kept in operation up to the present time."

You wonder why this machine did not come into general use, and why Bell is not called the inventor of the reaper. The cutting part of Bell's machine, as in all the early reapers, was not satisfactory. If the grain was ripe, stood up well, and was free from grass and weeds, it went satisfactorily. But if the grain was down, and there was an abundance of weeds and grass, the machine choked, running over the wheat without cutting it. As a rule, only about four fifths of a field could be harvested with this machine; the remainder had to be cut with the cradle. Again, farmers were not accustomed at that time to machinery. Besides, the fields in England were small, and labor was plentiful. English farmers did not have much trouble in harvesting what grain they could raise. There was not, for these reasons, very much encouragement in England for an inventor to make the sacrifice to perfect a machine and to educate the people to buy and use it. Still, if Bell is not to be called the inventor of the reaper, it should be granted that he made the first reaping machine used to any considerable extent.

The Man Who Succeeded

Although Bell's reaper cut grain with some success, people went on harvesting their wheat with the sickle and cradle, almost as if his invention had not been made. But not long afterwards, a reaper was invented which, when perfected, was used in all parts of the world. This reaper took the place of the sickle and the cradle; it increased, many times, the amount of wheat raised, and it relieved the farmers of the back-breaking work of cutting and binding grain by hand. The man who took the chief part in the invention and improvement of this reaper was an American, Cyrus H. McCormick, born in 1809, near Midvale, Virginia.

Robert McCormick, the father of Cyrus, was a farmer, who, like many other farmers of the day, did other things besides farming. On his ample farm of 1800 acres, there stood a sawmill and a gristmill. There was also a blacksmith shop of goodly size, where the father not only made and repaired the tools used on the farm, but often tried his hand at invention. A reaping machine was his hobby. He was at work on this as early as 1816, and continued to busy himself with it until 1831. At the time it left his hands, the cutting part was made up of whirling saws eight to ten inches in diameter, which revolved like shears past the edge of stationary knives. A reel pressed the grain against the cutters, and pushed the cut grain upon a platform. When there was enough cut grain on the platform to make a sheaf, it was raked to the ground by a man who followed along beside the reaper. This machine was at last tested in the early harvest of 1831, but the cutter would not work.

Cyrus H. McCormick, the oldest of a family of eight children, grew up like many another country boy, familiar from childhood with farm life. He prided himself on knowing how to do every kind of farm work, and how to run and repair every bit of machinery in use. The winter months he spent in the near-by "Field School," studying reading, writing, and arithmetic, and the rest of the year was given to work, either on the farm, in the mills, or in the shop. By the time he was twenty-one, Cyrus was as big and strong as any man in all the region round about; he was a good farmer, and was skilled in the use of blacksmith tools. Like his father, he had a fondness for making things and for invention.

McCormick's First Reaper

When Robert McCormick, the father of Cyrus, drew his crude reaper out to a field of wheat in the early harvest of 1831, to make a trial of the invention on which he had spent fifteen years, Cyrus, you may be sure, was more than an onlooker. He had doubtless had a considerable part in the making of this machine. So when it choked down and would not cut, he was probably even more disappointed than his father. But when the disappointed father said, "I am through with it; it is impossible to make a practical reaping machine," not so with Cyrus. The surrender of the father was the call of the son to battle. Then and there Cyrus resolved to make a successful reaper. The machine was pulled back to the blacksmith shop, and Cyrus took up the work where his father left off.

To improve the cutting part of the machine, Cyrus made a sickle bar, to carry a moving sickle, with wire guards extending forward into the grain. The sickle was made of a thin bar of steel, on the edge of which were filed sharp, saw-like teeth. A divider was attached to the outer end of the sickle bar, and extended forward, to separate the grain to be cut from the grain to be left standing. These two changes were probably the only ones made on his father's machine in the summer of 1831. Cyrus was anxious to give the new kind of cutter a trial. So before the last oats were cut, the improved machine was taken back to the field. The new cutter worked so well that Cyrus felt he was on the right track.

By the harvest of 1832, the improved machine probably looked very much like the machine patented in 1834. At all events, Cyrus felt ready to take his machine out into the "wide, wide world." A public exhibition was given near Lexington, which was attended by the farmers and laborers for miles around. The field in which the trial was to be made was very rough. The machine did not work well, and it looked for a time as if it also were a failure.

"Here," shouted the owner of the field, "stop your horses. That won't do, you are ruining my wheat."

This delighted the laborers, who feared that the machine would take work away from them.

"It's a humbug," shouted one.

"Give me the old cradle yet," cried another.

All this, you may be sure, was discouraging enough to the farmer-inventor. But farmers like fair play.

MCCORMICK'S MACHINE, 1831-1834, CUTTING A FIELD OF OATS.

"I'll see that you have a fair chance, young man," said a farmer. "That field of wheat on the other side of the fence belongs to me. Pull down the fence and cross over."

Cyrus pulled down the fence and crossed over. The field was level, and before sundown he had laid low a full six acres of grain.

With this unheard-of feat accomplished, the machine was driven into Lexington and exhibited at the courthouse square. One spectator, after looking it over carefully, said, "This machine is worth a hundred thousand dollars."

Probably quite as agreeable to Cyrus were the words of his father: "It makes me feel proud, to have a son do what I could not do."

The general feeling of most of those who saw the machine on that day was, however, probably expressed by a certain lady, who said, "I thought it was a right smart curious sort of a thing, but that it wouldn't come to much."

Selling Reapers in the East

McCormick advertised in the local newspaper, reapers for sale, as early as 1833. But it was seven years before he sold his first machine. To be sure, between 1833 and 1839 he was engaged with his father in running an iron furnace, and gave little time to his invention. The iron business, however, proved a failure, McCormick losing everything. The reaper was all he had left. He now turned to it to help him out of his financial troubles, exhibiting it in the harvest of 1839. Though he cut as much as twelve acres of grain in a day, no one wanted to buy. To the farmers of that time the machine was not only costly,—the price was fifty dollars,—but it was also very complex. "It can be run," said the farmers, "right well, by one who knows all its cogs and levers, but we are running farms and not circuses."

Most persons would have been discouraged, would have given up. McCormick was not that kind of man; he worked even harder than before. He succeeded in selling seven machines in 1842, twenty-nine in 1843, and fifty in 1844. This was big business.

Best of all, seven reapers were ordered from the West. These seven orders gave great joy to the McCormick brothers, who were now all busy at the old blacksmith shop, turning out a reaper a week. But when the question how to get reapers out to Ohio, Missouri, Iowa, Illinois, and Wisconsin arose, Cyrus saw that the old "home farm" was no place to make reapers, if these were to be sent to the West.

About this time a friend remarked, "Cyrus, why don't you go West with your reaper, where the fields are large and level, and where labor is scarce?"

McCormick decided that this was the best thing for him to do.

In a few days he was on his way. He traveled by stage through Pennsylvania, by boat along the lake ports, and on horseback over the Middle Western States. It was the first time he had seen the prairies, so broad and level and fertile. They seemed made for his reaper, and in Illinois he realized how greatly the West needed it. The bounteous harvest was too much to be cut with the cradle, and hogs and cattle had been turned into great fields of over-ripe grain.

"With my reaper," thought McCormick, "millions of bushels of grain can be saved, which are now left to rot on the ground. Here and there in Virginia, a farmer can be persuaded by hard work to buy a reaper, but the West,—the West must have the reaper."

CARRYING THE REAPER TO THE WEST

Returning home, McCormick brought together all the improvements he had made in his machine since his first patent, and took out a new one in 1845.

He was going West, but where should he locate? St. Louis, Detroit, Cincinnati, and Cleveland were cities of good size, and each offered some special advantage. But McCormick studied the maps, saw where the railroads were going, and observed where the people were settling. He finally chose Chicago. This was one of the most fortunate decisions in his long and successful career.

When McCormick voted for Chicago, he had neither money nor credit. To start in business, he must find a man to furnish him with the needed money. McCormick called on William Ogden, at that time Mayor of Chicago, and told him of his invention, of his success, and of his new plans. On hearing McCormick's story, Ogden said, "You are just the man we want. I will give you twenty-five thousand dollars for a half interest in this reaper business of yours, and we will build a factory at once." The factory was built, and five hundred reapers were manufactured for the harvest of 1848, and fifteen hundred for the harvest of the next year. The making of reapers on a large scale in the West was thus a success from the first.

At the end of the second year, McCormick said to Ogden, "For your share of the business, I will pay you back the twenty-five thousand dollars you invested, and will give you twenty-five thousand besides for interest and profit."

Ogden, having many other interests, gladly accepted this offer; he had doubled his money in two years. McCormick now had a factory of his own, and the commanding position of being the inventor and successful maker of the reaper. He was well on the way to a great fortune. From this time on, he had no partners except his brothers, who joined him in Chicago, to help in the growing business.

The Self-Rake Reaper

The reaper did away with the hard work of cutting grain with the sickle or cradle. Farmers soon began to ask, "Why cannot a device be invented to do away with the even harder work of the raker?" In answer, a self-rake was invented in 1852, by Jearum Atkins, an invalid. Atkins had a McCormick reaper placed outside of his window. Day after day he sat in his chair and worked on an attachment which would of itself rake from the platform the cut grain. Success finally crowned his efforts, and McCormick, always anxious to meet the demands of the farmer, bought this invention.

MCCORMICK SELF-RAKE REAPER.

The farmers nicknamed the contrivance the "Iron Man." It was surely a spectacle to see its long rake fingered arm whirling up through the air, and then, descending to the platform, rake off the cut grain in great bunches ready to be bound. The self-rake saved the labor of from one to two men, and after 1860 farmers scarcely bought any other kind of machine.

The Marsh Harvester

The reaper by this time had taken away fully half the hard work of the harvest. There remained only the binding of the bunches of cut grain about the middle with a straw rope, so that the grain could be easily handled. This, to be sure, was back-breaking toil, but most of the farmers thought it would always have to be done by hand. "How can a machine ever gather the grain into bundles and tie bands about them?" they would ask.

An inventor by the name of Mann fitted a McCormick reaper, in 1849, with a canvas elevator, to carry the cut grain up into a wagon moving along beside the machine. Nine years later, two brothers by the name of Marsh were using a machine of this kind, when one asked the other, "Why should the grain be carried up to the wagon? Why can't we put a platform on the side of the machine to stand on, make a table all round to work on, and bind the grain as fast as it comes up?"

By the next harvest, the Marsh boys had their new rigging arranged. As they expected, they could bind grain nearly three times as fast as before. One of the brothers bound a whole acre by himself, in fifty-five minutes. They patented their device, and called it the Marsh harvester.

The Marsh harvester cut the cost of binding grain in two. The binders had no longer to walk from bundle to bundle, nor were they compelled to stoop over, each time they bound a sheaf. They could stand still and straight at their work. Two men could do what before it took five or six to do. Strange as it may seem, the Marsh harvester was not at first popular. The farmers called it a "man killer." The farm hands dubbed it the "Weary Willie." Like all good things, it soon won its way, and for more than ten years was the king of harvesters.

Besides reducing the cost and the drudgery of binding grain, the Marsh harvester was a long step towards what the farmers said could never be done. All that was now needed to do "the impossible" was to teach the Marsh harvester to twist a wire or to tie a knot.

The Wire Self-Binder

In the winter of 1874, Charles Withington, of Janesville, Wisconsin, carried to McCormick at Chicago a new invention. It was a remarkable device. Two steel arms caught a bundle of grain between them, put a wire tightly around the bundle, and fastened the two ends of the wire together by a twist. This was the long sought self-binder, the very thing the farmer said could never be made. A wire self-binder was built and tested in the following July. It cut fifty acres of wheat, and bound almost every bundle without a slip. Within the next five years, McCormick alone made and sold fifty thousand of these machines.

THE WIRE SELF-BINDER.

This was the end of harvest drudgery. Sickles, cradles, rakers, binders, each in turn were set free. From this time on, all that was needed was a man or a good-sized boy to drive the team and to manage the machine. The machine cut the grain, bound it into sheaves, collected these on a carrier, and dropped them to the ground, ready to be placed in shocks,—all without the aid of the human hand.

The Twine Self-Binder

There was one defect in the wire binder, which proved to be its undoing. The wire mixed with the straw got into the mouths of the cattle, and at times killed them. Pieces of wire mixed in the grain cut the hands of those handling it. So, while the farmers were delighted with the self-binder, they disliked the wire.

At the very time the wire binder seemed to be most secure in its position in the harvester world, John Appleby, of Wisconsin, took to William Deering, the chief maker of the Marsh harvester, an invention which he claimed could tie a knot more quickly and more securely than was ever done by sailor.

Deering knew the dislike of the farmers for wire.

"Here," he said to himself, "is the device to make the perfect binder, a binder that will use twine." And he forthwith accepted the new device without the slightest hesitation.

During the winter of 1880, word went about among the makers of binders that "Deering is crazy over a twine binder. Why, he is making three thousand of them."

Before the harvest of 1880 was over, the shoe was on the other foot, for Deering not only made, but he sold his three thousand twine binders, at a profit of one hundred thousand dollars.

By the next harvest almost every manufacturer was in the field with a twine binder, most of them paying a royalty to Appleby. The wire binder passed away almost as quickly as a summer shower. The twine binder took its place, and it is to-day the standard binder of the world.

With one of these machines, having almost human skill, a sixteen-year-old boy can harvest as much grain as a dozen strong men could harvest with the cradle, or even forty with the sickle.

The Complete Harvester

The final step in the improvement of the reaper was the invention of the complete harvester, which is really a harvester and thrasher in one machine. The complete harvesters are used, in our own country, chiefly on the Pacific Coast. They are great machines drawn by thirty to forty horses, or by an engine. They cut a swath from twenty to twenty-five feet wide, and a single machine will cut, thrash, clean, and sack from seventy-five to a hundred acres of grain in a day, all at a cost of not more than forty cents an acre.

The Worth of the Reaper

McCormick lived until 1884. He thus saw the reaper grow, from the time when he drove that crude machine back to the old blacksmith shop in July, 1831, until it reached its full maturity in the self-binder of to-day. With his own hand, he added the improvements which first made the reaper a success; in his own time, he was always the largest single maker of reapers, and he did more than anyone else to carry the reaper to Europe and the other countries of the world.

LARGE MODERN HARVESTER ON WESTERN PLAINS.

Chiefly because of the reaper, the amount of wheat produced in the world has increased by leaps and bounds, until it now amounts to about four billion bushels a year. To handle this enormous crop, great elevators are built along rairoads, at rairoad centers, and at seaports. A single elevator, like the "Jumbo" at Minneapolis, holds six million bushels. To grind this wheat, thousands of flour mills have been erected, some of which are so large that a single mill grinds seventeen thousand barrels of flour in twenty-four hours. Even the making of reapers has in itself become a great industry. One harvester company alone gives regular employment to an army of twenty-five thousand men and women.

Henry Bessemer and the Making of Steel

Iron is the most precious metal in the world. It is the most precious metal in the world, because it is the most useful. Without iron to make our stoves, kettles, knives, tools, engines, and railroads, we would be living to-day very much as the Indians lived when Columbus discovered America. Our cooking utensils, our tools, and our weapons would, to this very day, be of clay or wood or stone. Pound for pound, pure gold is, to be sure, worth more than pure iron. But when it is made up into useful articles, iron may be worth more than a corresponding weight of gold. A bar of iron, for example, worth five dollars, is worth ten when made into horseshoes, fifty-five dollars when made into needles, three thousand dollars when made into penknife blades, and twenty-five thousand dollars when made into balance springs for watches.

HENRY BESSEMER.

Primitive Iron Furnaces

In most of the countries of the world there is more or less iron ore. Yet people mixed copper and tin to form bronze, and fashioned bronze tools and weapons, long before they learned to use iron. The reason for this was that iron is not found like gold, copper, or tin, by itself. It is mixed with clay, or rock, or other substances, and in this form is called iron ore. To obtain the iron, the ore must be put under great heat. When this is done, the iron in the ore melts and runs out, and only then can it be collected and made into useful things.

IMPLEMENTS OF THE BRONZE AGE.

The first furnace in which iron ore was melted was probably no more than a pile of wood with a layer of ore on top. The entire heap was covered over with clay to keep in the heat. A large hole at the top and a number of holes at the bottom provided the needed draft. The reward for several days' work with such a furnace was a couple of pounds of iron. Yet the smith—a very honorable person among ancient peoples—forged from the iron obtained in this way, crude knives, axes, and spearheads that were superior to similar tools and weapons made of stone or of bronze.

PRIMITIVE FORGE IN NORTHERN EUROPE, 1600.

In the course of time, improvements were made on this method of smelting iron. Charred wood, or charcoal, which makes a hotter fire, came to be used instead of wood. A goatskin bellows was added to fan the fire. With a bellows to force the air into the furnace, the draft could be made stronger than when the air entered of its own accord, and still more important, the draft could be controlled. The furnace was then built so that it could be used over and over again. It was made of clay, and at least one form was four or five feet high and about five feet wide at the bottom. An opening was left in front, which was closed with clay after the furnace was filled with layers of charcoal and iron ore, and was broken down after each melting, so that the melted iron could be taken out.

CHARCOAL PIT.

One of these improved furnaces would supply from fifteen to twenty pounds of iron in a day, and there was at last, iron enough for knives, axes, spears, swords, chisels, saws, files, forks, reap hooks, harrows, and chains. When these improvements in the furnace were brought about no one knows, but they were all probably made long before the Israelites were in bondage in Egypt.

For more than two thousand years after this, there was little progress in smelting iron. What there was, consisted in building better furnaces, and in making them so that the charcoal and the iron ore could be put in at the top, and so that the smelted iron and the slag could be drawn off at the bottom. Such a furnace could be run for months, and even for years, without being allowed to cool down.

The Blast Furnace

About the time of Columbus, other improvements followed. Furnaces were built still larger, some of them as high as twenty or thirty feet. More powerful bellows also came into use, which were worked by horse power or by water power. These larger furnaces with the more powerful bellows, called blast furnaces, produced from two to three tons of iron a day.

The modern blast furnace dates, however, from the introduction of the steam engine. This did away with the bellows worked by horse power or water power, and made possible the use of blowers, which deliver a blast of air many times strong enough to blow a person off his feet.

Smelting iron required so much wood that countries like England became alarmed. It was feared that all the good timber would be burned up. A trial was made of soft coal, but it was not satisfactory. The custom of charring wood to make charcoal probably suggested the idea of charring soft coal, and using the coke, or charred coal. Coke answered very well for smelting iron, and its use became general in western Europe about 1750. But in the United States charcoal was employed until after 1865, and this accounts for the cutting off of the large trees, over great areas, in all our older states, like the Wilderness in Virginia.

Up to 1828, cold air was used to fan the fire. Then an ingenious Englishman made a great discovery. He found that if the air was heated very hot before it was forced into the furnace, the iron could be smelted with half the amount of fuel otherwise required.

The forced blast, the hot blast, and the use of coke are thus the important features of the modern blast furnace. These modern furnaces are built from seventy-five to a hundred feet high, and from twenty to thirty feet wide inside at the widest part. A single blast furnace of average size will turn out a hundred tons of iron a day, or it will produce as much iron as six to seven thousand of the furnaces of ancient times.

There is scarcely any limit to the amount of iron the modern blast furnace can produce. But the blast furnace has one drawback. The iron made in primitive furnaces could be hammered at once into tools and implements, and only the iron needed for knife blades, swords, and the like had to be refined, or changed into a finer kind of steel. The iron produced in a blast furnace, called pig iron, will not bend, and it cannot be hammered. It can be melted and molded into castings, such as stove tops and stove lids, but before it can be pressed or hammered into useful things, it has to be refined. To change pig iron into the higher grades of steel needed to make delicate machines and fine tools, such as knives, axes, saws, and chisels, was at this time very expensive. The best pig iron could be bought in London for thirty to thirty-five dollars a ton, but a ton of high grade steel cost from two hundred and fifty to three hundred dollars.

The invention of the steam engine, the steamboat, the locomotive, the sewing machine, and the like, increased the amount of good steel that was needed. It seemed that the progress of the world was to be halted, unless some way was found to change the cheap pig iron, of which there was an abundance, into steel, at less expense. What the world needed was some one to do for the making of steel, what Crompton had done for spinning, Whitney for cotton growing, and McCormick for wheat raising. The man to do this was born at Charlton, England, in 1813. His name was Henry Bessemer.

Preparing for Work

In 1813, Charlton was a small country village. There among the woods and fields and country folk, Henry Bessemer lived. He received a good elementary school education, but he did not go to high school. Instead, he passed the years between the ages of thirteen and sixteen in doing whatever he wanted to do. Some of the neighbors said he was fooling his time away. However that may be, he was fond of working on a lathe which his father bought for him. He made working models of machines. One of these was a brick machine, with which he molded little bricks of white clay. He also molded, in type metal, wheels, pulleys, and other objects. "Often during my evening walks around the fields, with a favorite dog," he says in his autobiography, "I would take up a small lump of yellow clay from the roadside, and fashion it into some grotesque head or material object, from which I would afterwards make a mold and cast it in type metal."

Henry's father owned a big type foundry. This was a place of great interest. Many a day he spent there, cutting dies, molding type, and mixing different kinds of type metal. But the antimony used in making the type metal caused Henry on more than one occasion to become sick, and his sickness finally betrayed him.

"There was . . . one other attraction in the village, which played an important part in molding my ideas," he tells us. "I was very fond of machinery, and of watching it in motion. If ever I was absent from meals, I could probably have been found at the flour mill . . . , where I passed many hours, gazing with pleasure upon the broad sheet of water falling into the . . . buckets of the great . . . water wheel; or, perhaps, I might have been watching, with a feeling almost of awe, the large wooden spur wheel, which brought up the speed, and which was one of the wonders of millwright's craft in those days."

BESSEMER BUYING MEDALLIONS FROM A VENDER.

By the time Henry was seventeen years old, he was full grown, a little more than six feet tall, and full of energy. He was to become the Thomas Edison of England. But he did not set to work with any big plan in mind, as to how he was going to become the most famous inventor of his age. He merely had wide-open eyes, and did the thing before him which seemed worth doing.

Making Art Castings and Stamping Dies

On one of his rambles about London, where his parents moved in 1830, young Bessemer met with an Italian selling plaster casts "of the most beautiful medallions, real works of art, at one penny apiece." He bought a number of the most beautiful of the medallions and took them home, to cast them in metal. After working with the very greatest patience for more than a year, he not only succeeded in casting medallions in metal, but he perfected his way of casting, so that he was able to reproduce in metal, rosebuds, flowers, ferns,—indeed any natural object,—with all the delicate curves and fine lines. He also found a way of putting a coat of copper on his casts, so that they looked as if they were made of bronze.

His casts were really beautiful, and attracted attention even among artists. Thus by following out a boyish interest, and by putting to use the skill he had acquired, Bessemer was started on his great career. The neighbors, meanwhile, complained that the young man was allowed to fool his time away.

While busy with his art castings, his attention was called to the use of dies to stamp raised figures on cardboard and leather. It was a short step from making molds to cast medallions and flowers, to making dies to stamp raised figures. Then, too, Bessemer had made many a die at Charlton when "fooling his time away."

"After a certain amount of practice," he tells us, "I produced a great many very beautiful dies. . . . I erected a powerful 'fly-press' for stamping impressions from these dies.

"It will be easy to imagine my delight on securing my first order for five hundred copies, on . . . cardboard, of a beautiful cartoon of Raphael. These impressions cost me only three pence each . . . , and I found ready sale for them at a half crown.

"I also made a great many dies . . . for bookbinders, cardboard manufacturers, etc., this turning to commercial account the art of 'fine casting,' which I had heretofore only pursued as an amusement."

Making a Stamp Die for the Government

While thus engaged, Bessemer learned that the government was being defrauded of probably five hundred thousand dollars a year, by people taking stamps from old and useless deeds, and using them on new deeds. Bessemer thought a stamp could be made which would prevent this fraud. Everything else was set aside and neglected, for this great object was to make his fortune. After some months, the die was completed. It was made of steel, and punched four hundred little holes in the parchment, each one of them forming a part of the design of the stamp. The die was no sooner finished, than Bessemer was off to the president of the Stamp Office. In triumph he said to himself: "A few more weeks will seal the fate of my life. If I succeed in saving the government so much revenue, they must reward me liberally. I shall then establish myself in a new home, and marry the young lady to whom I have for two years been engaged.

DESIGN OF BESSEMER'S DIE, 1833.

"The design gave great satisfaction . . . , and the Stamp Office authorities decided to adopt it. I was then asked if, instead of receiving a sum of money from the Treasury, I should be satisfied with the position of Superintendent of Stamps, at three or four thousand dollars a year. This was all I could desire. . . . A few days after this . . . , I called on the young lady to whom I was engaged, and showed her . . . my new . . . stamp. I explained to her how it could never be removed and used again . . . , when she at once said, 'Yes I understand this; but surely, if all the stamps had a date upon them, they could not be used again without detection.' While I felt pleased and proud at the clever and simple suggestion of the young lady, I saw also that all my more elaborate system of piercing dies, the result of months of study, and the toil of many a weary and lonely night, was shattered to pieces by it."

Bessemer felt in honor bound to present to the authorities the new die with the movable dates. It was so simple that it was adopted and is in use even to this day. But the new die was so simple that there was no need of a superintendent of stamps at four thousand dollars a year. Bessemer thought, of course, that the government would pay him liberally for his nine months of labor. At first there were half promises of reward, but the Stamp Office finally told him that he had offered the die to the government of his own free will, and that there was no money to give him. "Sad and dispirited, and with a burning sense of injustice overpowering all other feelings," he says, "I went my way from the Stamp Office, too proud to ask as a favor that which was . . . my just right."

This was a hard blow for a young man who thought he all but had a good position for life, and could marry at once the girl he loved. He was, however, not altogether discouraged. "I have made one good invention," he said to himself, "and I can make others. I will keep my eyes open for a 'good vein,' and when I find it, I will work it for all it is worth." For the next four or five years, he was busy with a number of inventions, when by accident he discovered the first of the "good veins" he was to find.

Making Bronze Powder

Henry's sister asked him one day to letter the title and her name on the cover of a flower book. The book was so beautiful that Henry thought common ink would not look well enough. He decided to do the letters in a paint made of bronze powder, so that they would look as if they were made in gold. When he went to get the bronze powder, he was astonished to learn that a little ounce bottle cost a dollar and a half. Most of us would have grumbled at the price, then paid it, and gone our way. Not so with Bessemer; his eyes were wide open for a "good vein."

"On my way home," he tells us, "I could not help asking myself over and over again, 'How can this simple . . . powder cost so much money?' for there cannot be gold enough in it, even at that price, to give it this beautiful rich color. It is probably only a better sort of brass; and for brass . . . a dollar and a half an ounce is a marvelous price."

Bessemer hurried home and with a little acid convinced himself that there was no gold in the powder. Here was powdered brass, selling at twenty-two dollars a pound, and the brass itself only cost twenty-two cents a pound.

"This powder must surely be made," he said to himself, "by some old-fashioned hand process, and offers a splendid opportunity for gain, if I can construct a machine to make it."

Bessemer set about making a machine that would change, at small cost, a solid block of brass into powder as soft and fine as flour. The first machine he built reduced the solid brass to powder, but when the powder was worked up into paint, it was dull, and lacked the beautiful color which gave value to the powder. "This," he tells us, "was not the first castle I had built, only to see it topple over."

BESSEMER LETTERING HIS SISTER'S ALBUM.

For about a year after this, Bessemer was occupied with other things. But the idea of making a machine which in an hour would give to a pound of brass the value of an ounce of gold haunted him. With the aid of a microscope he studied the bronze powder he had bought, and that which he had made, and saw why his powder was worthless. He then designed and made with his own hands a number of working models, one to cut the brass, another to roll the tiny particles, another to polish them, and finally one to sift the powder. "At last after months of labor, the great day of trial once more arrived. . . . I felt that on the result of this . . . trial hung the whole of my future life's history, and so it did . . . I watched . . . with a beating heart, and saw the iron monsters do their appointed work."

Bessemer was now sure that he could make bronze powder. He interested in the new enterprise a friend who advanced fifty thousand dollars to build a factory. A patent would give no protection to such an invention. If they were to profit by it, everything must be kept a secret. So Bessemer worked for almost a year in designing all by himself the different machines.

To keep even those who had made the machines from having an idea of what they were for, the different parts of each machine were give out to be made at different places. The old "Baxter House," to become famous because of the many inventions made there in after years, was bought and fitted up for a factory. Here, at length, all the machines were assembled and put in place. To carry on the work,—and there was not very much to do, for the machines were all self-acting,—the three brothers of Bessemer's wife were employed, at extra good wages. They kept faithfully a secret for which at any time they might have received thousands of dollars. The secret did not become known for many years.

The profits from making bronze powder by this new process were enormous. Powder which cost a dollar and thirty cents a pound to make was sold at a dollar and thirty cents an ounce. From these profits, Bessemer had ample means to support himself and his family. What was quite as important, he had ample means to carry out and bring to completion the many other inventions born of his active mind. Thus this invention had a profound effect on Bessemer's life. It freed him, at the early age of thirty, from anxiety about the comfort of his family, gave him the use of all of his time, and supplied him with the money necessary to carry on his experiments.

His Master Invention

During the next dozen years, Bessemer was busy with many different projects, and he took out no less than thirty patents. This brings us to 1854, when he was at work on a new kind of ball or projectile for cannon.

"If you cannot get stronger metal for your guns," said an army officer one day, "such heavy projectiles will be of little use." This remark set Bessemer at work to find a way to produce a metal from which big guns could be cast, and this led to the discovery of his now famous process of making steel.

To refine, or to change pig iron into steel, at that time, the common way was to break up about seventy pounds of pig iron into small pieces, and place them in a tub-like arrangement, over which poured a very hot flame. As the pig iron melted, a man called a puddler stood by and stirred the molten mass so that the flame and air reached all parts of it. After two or three hours of stirring, the liquid iron formed into grains. The heat was then increased until these grains melted and ran together. When this had occurred, the flame was shut off, and the puddler collected, on the end of an iron bar, the cooling metal in a ball-like mass called a bloom. The bloom was then put between great rollers, and rolled, reheated, and rolled again and again. Or it was hammered, reheated, and hammered over and over. It was this long process, expensive both in fuel and labor, that made steel cost so much.

PUDDLING MOLTEN METAL.

At the old "Baxter House," Bessemer built a puddling furnace very much like those in common use at that time. One day, when working with his furnace, he noticed two pieces of pig iron on the inside which did not melt, although the heat in the furnace was great. About a half hour later, he observed that the pieces were still unmelted. It occurred to him to take one of them out and examine it. To his surprise, what he thought was a piece of unmelted pig iron turned out to be a piece of steel. He saw from this that if air was forced into the molten pig iron when under great heat, the iron would be changed into steel. A small furnace was built, and Bessemer proved to his own satisfaction that good steel could be produced in this way.

Most people would doubtless have been satisfied with so great a discovery and stopped. But to Bessemer's inquiring mind, this question came: "Yes, pig iron can be changed into steel by forcing air into the molten metal when fuel is used; but can steel be made in this way, without the use of fuel?" The answer to this question changed the history of the world.

BESSEMER CONVERTER.

Bessemer next built what he called a converter. It was about four feet high, and around the bottom were six pipes extending inside. The pipes were connected on the outside with a chamber into which air was driven by a forced draft.

When all was ready, the draft was turned on, and about seven hundred pounds of molten pig iron were poured into the converter. Except for a few sparks that came from the top, everything went on quietly enough for about ten minutes. Then things began to happen. Clouds of sparks and a roaring flame burst from the top. This was followed by a few mild explosions, and then the converter became a young volcano in active eruption. Slag and white-hot metal were thrown high into the air, and the converter rocked, as explosion followed explosion. All this was a surprise to Bessemer, and for a time he was fearful of his life. In another ten minutes the eruptions had ceased, the flame had died down, and all became quiet again.

MODERN TYPE OF CONVERTER.

The molten metal, hotter than ever metal had been heated before, was drawn off and molded into an ingot. Best of all, it was steel of good quality. Thus was born the most ferocious of all the machines used by men, and one of the greatest of all inventions. "What all this meant," says Bessemer, "what a perfect revolution it threatened in every iron-making district in the world, was fully grasped by my mind as I gazed on that glowing ingot, the mere thought of which almost overwhelmed me for the time."

Bessemer now worked to adapt the new process to commercial use. A number of different converters were made, and finally he hit upon the form which has since been in general use. By early August, 1856, he was ready to take out a patent on his invention, which came to be known the world over as the "Bessemer Process." Thus, in seven months, this great inventor brought forth an invention which changed iron into steel in twenty to thirty minutes, and which reduced the cost of making good steel from two hundred dollars to three or four dollars a ton.

The new invention was scarcely finished before Bessemer read a paper before a meeting of iron makers. The title of his paper, "The Manufacture of Iron (Steel) without Fuel," was the object of many a joke. "We will be burning ice next," remarked one iron maker. "Clay," said another to his friend, "I want you to come with me . . . this morning. Do you know that there is actually a fellow come down from London to read a paper on the manufacture of malleable iron without fuel?" Nevertheless, Bessemer's paper was the sensation of the meeting. Iron makers flocked to "Baxter House" to see the new process. In less than a month, Bessemer sold to the iron makers of England licenses to use the new process, to the amount of one hundred and thirty-five thousand dollars. Greater honor and greater wealth than he had ever dreamed of seemed easily within his reach.

Saving the New Process from Failure

Then, lo! the new process proved to be a failure. The steel made by it was good for nothing. The newspapers denounced "the whole scheme as the dream of a wild enthusiast, such as no sensible man could for a moment have entertained." One paper spoke of Bessemer's invention as "a brilliant meteor that had flitted across the . . . sky for a short space, only to die out in a train of sparks, and then vanish in total darkness." These criticisms stunned Bessemer. He went out to the different furnaces and saw for himself the utter failure of his process.

Something was wrong, but he had no idea what it was. Should he give up and admit his failure, or should he go ahead? Bessemer was no "quitter." To protect his family, he gave his wife fifty thousand dollars; this left him sixty thousand, and he resolved to spend the last penny of it, if need be, to prove the worth of his invention.

One expensive experiment followed another, only to end in heartbreaking failure. A whole year, then another half year glided by, with nothing accomplished except that thousands of dollars were spent, and Bessemer was much worn from hard work and anxiety. Those who had something to lose, if his invention was a success, sneered at his efforts. His friends tried to get him to give up a project which experience had shown was worthless. Those dearest to him grieved over his obstinate perseverance. But what could he do? His reputation had been injured; he had spent the greater part of three years and a goodly fortune on the invention, and he believed in it. To give up was to surrender his reputation, his time, the money he had invested, and the fame and wealth which he knew would be his if he succeeded. Happily the end was near.

MAKING PIG IRON.

The pig iron produced at this time in England contained considerable phosphorus, and phosphorus was found to be the enemy of the new process. Work as he would, Bessemer could not make good steel out of pig iron with phosphorus in it. He had made good steel, and this led him to wonder what kind of pig iron he had used. He learned that this pig iron came from Sweden, and that it contained no phosphorus. Pig iron from Sweden was immediately ordered. On its arrival, no time was lost in melting it and putting it into the converter. You can well imagine Bessemer's anxiety about the outcome. When the molten mass was turned out of the converter, it was steel of an excellent quality. Not long after this the discovery was also made that with a little care quantities of pig iron could be produced in England, free from phosphorus. It was now Bessemer's turn to laugh.

Making the Process a Success

Bessemer seemed for a time no nearer to success than before. When he talked to steel makers about buying licenses, they said: "Oh, this is the thing which made such a blaze two years ago and which was a failure." Not a single steel maker in all England would buy.

BLAST FURNACE.

Bessemer saw that if his process was ever to be adopted, he must build a steel plant of his own. A plant was started at Sheffield, and Bessemer produced as good steel for fifty dollars a ton as was being sold at that time for five times this sum. "The only reason," he says, "why the plant was not burned down, was that nobody thought it would come to anything."

When the new steel was made, nobody would buy it. If Bessemer talked to a toolmaker about using some of his metal, he was met with the reply, "Well, perhaps it is good enough for rails; anything is good enough for rails." On asking a railroad engineer to recommend the use of steel rails, the engineer exclaimed, "Mr. Bessemer, do you wish to see me tried for manslaughter?"

AN IRON MINE IN MINNESOTA.

Bessemer's steel was, however, too good, and the price at which it was offered was too attractive to be resisted long by the greedy world. Here and there a toolmaker began to use a little. It was satisfactory, and he bought more. The steel makers, seeing there was demand for new metal and that they were being undersold in the market, rushed to Bessemer to obtain licenses to use the new process. Thus began one of the greatest industrial revolutions in modern times. Bessemer's steel gradually found its way into tools, engines, steamboats, cannon, warships, bridges, skyscrapers, and a million other useful things. His royalties from the invention, which even his best friends had at one time considered worthless, amounted to no less than five million dollars.

So many uses were found for steel, when once it could be made at small cost, that the present is called the "Age of Steel," and its manufacture is one of the great industries of the world. Great waste regions, like the Mesabi Range of Minnesota, because of the iron ore they contain, have become more valuable than gold mines. To transport the enormous quantities of iron ore needed, railroads have been built and steamboat lines constructed, which carry nothing else. Large cities like Pittsburgh have grown up about steel, and cities like Gary, Indiana, have been located and built for the sole purpose of making it. Billions of dollars are invested in this great industry, and millions of people are employed in it.

STEEL CONSTRUCTION SKYSCRAPERS.

Without steel that is both good and cheap, we would not have many of our finest and more delicate tools and instruments; we would not have our giant engines, and locomotives, and steamboats; we would not have great bridges, like the Brooklyn Bridge, or our mammoth buildings, and without these and other useful things made of steel, our lives would be very different from what they are, and the whole industrial world about us would be changed.

No wonder Bessemer has been called the "Captain of Modern Civilization," that his discovery is ranked with the printing press and steam engine as one of the three greatest inventions in the history of the race, and that his fame is as wide as the world.

John Gutenberg And The Invention Of Printing

When Christopher Columbus was a boy, there were few books. Those he might have read were of two kinds, manuscript books and block books. Manuscript books were copies of the Bible, or of books of the Greeks and Romans, written out by hand.

PRESS WORK AND TYPESETTING, 1564.

Persons called copyists made a business of drawing or writing manuscript books. Most of the copyists were monks, who lived in monasteries, where often there was a room set apart for their work, called the writing room. Copying was slow work. To copy a book like the Bible took all of a year, and when this was done well it took two or three years.

Manuscript books were written on parchment or vellum. Parchment is made from the skin of sheep and goats; vellum from the skin of very young lambs and kids. The hair is cut from the skin. The skin is put in a mixture of water and lime, and kept there until the fat is removed. It is then taken out, and stretched and rubbed with pumice stone and lime, until thin and smooth.

The parchment and vellum sheets used in the manuscript books were, as a rule, ten inches wide and fifteen inches long. Broad margins were left on all sides. The first letter of the word beginning the first paragraph on a new page was omitted, as was here and there an important word.

MONK WRITING ON VELLUM.

When the copyist had finished his work, the separate sheets were turned over to the illuminator or illustrator. The illustrator filled in the margins with a border of flowers or of foliage, interwoven with birds, animals, angels, or saints. The borders were drawn in blue, green, purple, brown, silver, or gold. The important words omitted were written in color, while elaborate initial letters were painted in at the proper places. These decorations gave to the best manuscript books an elegance and beauty beyond anything to be seen in books at the present time.

The illumination or decoration completed, the separate sheets were passed to the book-binder. Books of large size were bound in boards which were sometimes two inches thick. If the binding was not to be ornamented, the board backs were covered with pigskin. If it was to be ornamented, the covering liked best was calf or goatskin. Upon the ornamentation of the bindings of the best books, there worked gilders, jewelers, engravers, and painters. Some of the most famous books were covered with enameled brass, others with ivory, and still others with gold and silver studded with precious stones.

ILLUMINATING PAGES OF A MANUSCRIPT BOOK BY HAND.

Because of the work put upon them, manuscript books were sold at a high price, and only the rich could afford to buy them. A Bible, only fairly well written and bound, cost from a hundred and fifty to two hundred dollars. At that time the wages of a laborer were fifteen cents a day, the price of a sheep twenty-five cents, of a cow two dollars, and of a horse five dollars.

Block books, on the other hand, were mostly plain, and made up of a few pictures or of illustrations, interspersed with printed explanations or religious precepts. The Evangelists, the first of the block books, had, for example, thirty pages. Fifteen of these were printing, while the other fifteen were full-page pictures. The Bible of the Poor, the most famous of the block books, consisted of forty pictures. These were seven and a half inches wide, and ten inches long.

The block books were so named, because they were printed from carved or engraved wooden blocks. In making a block book, a piece of oak, ash, cherry, or apple wood was cut two inches thick, and the width and length of the desired page. One side of the block, or the face, was smoothed and polished. On this was placed a drawing of the picture, and of the writing to be printed. The surrounding parts of the block were then cut away, so as to leave the picture and the letters of the writing raised, or in relief, making a sort of stamp. This carving required much skill, and the engraving of a single book consumed weeks and even months.

PAGE OF THE BIBLE OF THE POOR, A BLOCK BOOK.

The engraving completed, the rest was easy. The carved block was covered with a coat of thin ink. A sheet of parchment or paper was placed upon it and pressed gently with the flat back of the inking brush. This transferred an impression of the carved picture and writing to the parchment or paper. The different printed sheets were then bound together.

Any number of books could be printed from the same set of blocks; for this reason block books were cheap. The ABC's  and the Lord's Prayer  cost two cents, the Catechism  twenty cents, Donatus or Boys' Latin Grammar  twelve and a half cents, and the Bible of the Poor  two dollars. But only small books could be multiplied in this way, for the carving of the blocks was slow work. To prepare the blocks to print the Bible would take at least thirty years, which of course was never done.

Birthplace And Parents Of John Gutenburg

John Gutenberg changed all this. He did it by inventing the art of printing from movable type.

Gutenberg was born about the year 1400, at Mainz, a German city on the Rhine, near Frankfort. His parents were of noble blood, and people of means, who took a prominent part in the affairs of the city. Nothing is known of Gutenberg's boyhood days, other than that they were passed amid scenes of strife between the common people and the nobility.

Learning Two Trades

When John Gutenberg was a boy, it was thought beneath the dignity of one of noble birth to do any ordinary labor, or to learn a trade. Despite this belief, he learned not one, but two trades. He learned the art of cutting and polishing precious stones, and of mirror making.

It is not an easy task to-day to learn a trade. It was even more difficult when John Gutenberg was a boy. The trades at that time were in the hands of guilds, or, as we would say, trade-unions. Of those in a trade, only the master workmen were allowed to teach it. The number of boys a master workman might take to teach was limited. The boy while learning the trade, which took from five to seven years, received no wages. Instead, he often had to pay a considerable sum for his instruction.

A boy on undertaking to learn a trade became an apprentice. As an apprentice, he ran errands, brought tools and materials, took care of the shop, and assisted in other ways. After two years or more, he rose to be a journeyman and served a second two years. In this period, he learned how to handle and to use tools, and how to do simple kinds of work. In the last two or three years of his service, the journeyman conquered the more difficult parts of the trade. As a kind of final examination he made what was called a masterpiece. This was examined by a committee of master workmen. If they were satisfied with his workmanship, he was admitted to the guild at a great banquet held at his expense, and given the right to set up in business for himself.

A long time to learn a trade? Yes. But John Gutenberg learned two, and at thirty-five was well established at Strassburg with a good paying business. He was also sought out by young men wishing to become cutters of precious stones or makers of mirrors, and was paid for teaching them these arts.

Printing From Movable Type

The idea came to Gutenberg, that all words, all writings, all languages are expressed in a small number of different letters. Our language has, for example, only twenty-six letters. With a large number of letters properly set together, a whole page of text could be printed at once. By resetting the different letters, and by repeating the process of printing, large books could be swiftly multiplied. This idea took possession of him, and after 1436, to the neglect of everything else, he gave his time, his energy, and his fortune to working out the process.

The Discovery Of Type Metal

Should you go into a newspaper office and see a printing press print, cut, paste, fold, and deliver in sixty minutes forty-eight thousand newspapers of sixteen pages each, it would be natural to think that the most important part of printing is the press. The most important part, in printing, however, is the type, or the little movable metal letters. For this reason, the key to inventing printing lay in finding the right kind of metal, and in finding an easy way of making type.

Knowing that block books were printed from carved blocks, Gutenberg first tried to make type from wood. It would seem easy to do this. Yet it proved difficult to carve a good letter upon the end of a small wooden stick. It proved equally hard to cut the sticks of such width that there would be equal spaces between the letters. Even when Gutenberg succeeded in doing this, for he was an expert carver, the ink so softened the wooden type, that after a few impressions the printed letters became blurred. As the printed letters must be clear and distinct, Gutenberg was forced, much against his will, to give up trying to make movable type from wood.

It now occurred to him that lead would serve. From his work in making mirrors he knew how easy it was to mold it. With a simple mold he cast a number of small lead sticks of uniform width and height, and then with no great difficulty he carved a letter on the end of each stick. He seemed to be on the direct road to success, but when he came to print from lead type, he found that it took more pressure than with wooden blocks, and when the pressure was sufficient to transfer the impression to the paper, the lead letters were flattened out.

Since lead was too soft, Gutenberg thought that iron might do. It proved difficult to mold small iron sticks. The iron stuck to the mold, and the sides of the little sticks were so rough that they would not fit closely together. Expert as Gutenberg was, it was slow work to cut the letters. Worse yet, when the letters were cut, so much pressure had to be used in printing, that the hard iron type cut into the paper.

These attempts at making type from wood, lead, and iron took weeks and months. Thus a great deal of time and labor seemed lost. Yet this was not all true; for Gutenberg learned from these trials that a metal would have to be found, out of which to make type that could be easily cast. He learned that this metal would have to be harder than lead, but softer than iron. He also learned from trying to cut metal letters, that a mold would have to be invented in which the type could be cast.

As lead could be easily molded, and was at that time one of the cheapest metals, Gutenberg set about finding a metal to mix with lead, to give it the needed hardness and toughness. Many are the mixtures he must have tried. On one day, this and that combination of lead and copper was tested. On another, lead and brass were combined, now in this and now in that way; and so on, week after week, month after month. Some of the combinations were fairly good, but Gutenberg was never satisfied with half success. He worked on and on, until he hit upon combining five parts of lead, four parts of antimony, and one part of tin. The lead supplied the bulk of the type, the antimony the hardness, and the tin the needed toughness. This mixture of metals proved satisfactory. Strange as it may seem, it is about the one used to-day. No better combination of metal for type has ever been found. It is known as type metal, and is only one of the great discoveries of Gutenberg.

Inventing The Type Mold

While Gutenberg was trying to find a metal suitable for type, he was at the same time working upon a mold. Unless an easy way of casting metal type could be found, printing from movable letters could never be made a success.

To understand what he really invented, let us see what tools are now used in making type. The most important of these tools are the punch or master type, the matrix or mold for the face of the letter, and the mold in which the body of the type is cast.

The punch is made by taking a bar of steel about six inches long, and of the width of a printed letter, and three or four times its thickness. Upon one end of this bar is drawn, say, an H. The surrounding parts of steel are then cut away until the letter stands out in bold relief. Each separate letter, both small and capital, requires a separate punch.

The matrix, or mold for the face of the letter, is made by taking a bar of copper half an inch thick, and about twice the width and four times the length of a printed letter. A punch is driven into this with a sharp blow. The result is the sunken imprint in the copper of the letter on the punch. This sunken letter becomes a mold for the face of the letter.

The mold consists of two halves. When these halves are put together, their inner sides face each other and form an opening. On the lower side of the mold, and just under the opening, is a place for fastening the matrix. On the upper side, the opening is left open for the inflow of the molten type metal. A dozen or more molds are needed for each set of type.

A, MATRIX, AND B, PUNCH OF THE LETTER H. THE CHARACTERS D, 1, E, ARE PRIVATE MARKS OF THE TYPE FOUNDER.

It was easy enough for Gutenberg to make a mold with which he could cast metal sticks of the same thickness. The difficult problem was to make one which would cast metal sticks of different widths, and at the same time form a letter on the end. He tried many ways of doing this. Months passed before the idea of a separate mold for the face of the letter occurred to him. Matrices were then made of lead, of iron, and of brass. In some, the impress of the letter was cast; in others it was cut or engraved. But no sooner was one made, than it was put aside. Still other months went by before he thought of the punch. Molds for the body of the type were made first in one way, then in another. Some were of iron, others of lead, and still others of copper, but not one would do. How many years he toiled, in hope and in despair, no one knows. We only know that by trying again and again, and never giving up, he learned that the mold should be of two like, adjustable parts and that the punch should be of steel, and the matrix of copper.

BEGINNINGS OF TYPE CASTING.

Thus by patient toil, Gutenberg invented the tools needed in casting type. With them he could easily cast two or three thousand letters a day. So well did he do his work, that more than four hundred years have made little changes in these tools, or in the metal from which they are made. Although type-casting machines are now employed, which cast a hundred type a minute, the punch, the matrix, and the mold invented by Gutenberg are in all important points like those in use at the present time.

Inventing The Printing Press

No press was needed in making either manuscript or block books. But when Gutenberg came to print from metal type, he discovered that considerable pressure was required to transfer the likeness of the letters to the parchment or paper. That this pressure might be quickly given and be uniform over the face of all the type, it became necessary to invent a press.

Gutenberg modeled his printing press after the wine press then in use. It had two upright posts of great strength. These were placed four feet apart, fastened at the bottom to a solid wooden base, and joined together at the top by a heavy crossbeam. The middle of this crossbeam held an iron screw worked by a lever. On the lower end of the screw hung a heavy block of wood called the plate, the under side of which was flat and smooth. By turning the screw, the plate could be forced up or down. Between the two upright posts, and upon the base of the press, stood a strong, four-legged stool, which served to support a heavy wooden platform, four feet wide and six feet long. Upon this was laid the form, or the wooden frame in which the type was locked. Crude as this printing press was, it served Gutenberg well, and presses like it were the only kind used for more than a hundred and fifty years.

The only ink at the time was the writing fluid of the copyists. Gutenberg found that when this was employed in printing, instead of forming a thin black coat over the type, it collected in drops and blotted the paper. Another kind of ink had to be made, if printing from metal type was to be a success. The Italian painters had lately invented a new paint composed of lampblack and linseed oil. It was probably from them that Gutenberg got a suggestion which turned him in the right direction. At any rate, he hit upon mixing lampblack and boiled linseed oil, and this mixture proved satisfactory. Printer's ink is still made in the same way.

Trouble At Strassburg

Gutenberg seemed to be standing upon the threshold of success, but events intervened to rob him of his reward. For a number of years he had worked night and day, upon different parts of his invention. Into it went, little by little, all the money he had saved, and all he had inherited. To be able to support himself and to continue his work he took three men into partnership. These men paid him a considerable sum of money for their part, and were to share in the profits of the enterprise. As was then the custom, they were sworn to secrecy. Their plan was to complete the invention and print a small religious book. Though Gutenberg and his partners worked steadily for two years, the invention was not complete before the Christmas of 1439.

GUTENBERG EXAMINING PROOF.

The cost of the enterprise, the faith of these men, and the will with which they worked are shown in a talk between Andrew Dritzehen, one of the partners, and a Frau von Zabern:

"But will you not stop work, so that you can get some sleep?"

"It is necessary that I first finish this work."

"But what a great sum of money you are spending. That has, at least, cost you ten guilders."

"You are a goose; you think this cost but ten guilders. Look here! If you had the money which this has cost, over and above three hundred guilders, you would have enough for all your life; this has cost me at least five hundred guilders. It is but a trifle to what I shall have to spend. It is for this that I have mortgaged my goods and my inheritance."

"But if this does not succeed, what will you do then?"

"It is not possible that we can fail. Before another year is over, we shall have recovered our capital and shall be prosperous."

Dritzehen died a few days later. His death left Gutenberg in a bad plight. The two remaining partners became discouraged and were ready to give up. Frau von Zabern told of her conversation with Dritzehen, and the circumstances of his death caused other people to talk. Gutenberg grew fearful that others would learn of the new art. He sent to Dritzehen's home, and warned the people there to let no one see the press. The molds and type he melted. George, the brother of Andrew, now demanded that he be let into the secret, or that the money Andrew had spent on the enterprise be paid back. Gutenberg refused to tell him of the nature of the undertaking, and claimed that instead of being in debt to Andrew, Dritzehen died in debt to him. The dispute was taken to court, where, after a year of delay, it was settled in favor of Gutenberg.

During the trial, witnesses spoke of the "secret work" Gutenberg was carrying on; they spoke of the "beautiful things," of the "costly things" he was making. No one knew just what he was doing. There was a lot of mystery about the whole enterprise. People began to say: "He doesn't want anyone to know." "He is not willing anyone should see." "Something is wrong." "He is practicing the Black Art."

So great was the prejudice against him, and he was now so poor, that it was impossible for him to go on. He went back to polishing precious stones and making mirrors.

Gutenberg was not long content, however, to work at his trade only. After a year or two, he began to think again of his invention, and to spend his evenings upon punches, matrices, and molds. He finally decided to return to Mainz, and set up a printing press.

Printing The First Bible

For four or five years after returning to Mainz, he did what we should call job printing. His success was so marked that a rich money lender became interested. Their plan was to print the complete Bible. It was to be printed in Latin, and was to look in every way like the best of the manuscript books.

The pages were printed in two columns of forty-two lines each. These columns, with the space between of five eighths of an inch, made a page eleven and a half inches long and seven and three fourths inches wide. Great spaces were left for initial letters, and a wide margin was allowed for a border. It often happened that the space for the initial letter and for the border was not filled in. Yet some of the early printed books rival in beauty of decoration the most famous manuscript books.

The entire Bible, when printed in this way, covered twelve hundred and eighty-two pages, and was bound in two large volumes. It is known as Gutenberg's first Bible, and was the first great work to come from the printing press. An undecorated copy on paper could be had then for four dollars. A decorated copy on vellum was lately sold in London for seventeen thousand dollars.

PART OF A PAGE OF GUTENBERG'S BIBLE.

Cheated By Fust

When Gutenberg entered upon the bold plan of printing the entire Bible, he thought he could have it ready for sale within three years. Plan and toil as he might, three years passed, four years went by, and it was late in the fifth, or towards the end of 1455, before the printed pages were ready to be bound. Yet at last, after five years of disappointment, hard work, and trials, the task was done, and the printed Bible was ready for sale.

But Fust, the money lender, did not go into partnership with Gutenberg to help him perfect a great invention, and to aid him in printing the greatest of all books. He thought that he saw in the new art a means of making money. He had invested a large sum in the enterprise. After five years, not one cent of this had been returned, nor had he received one penny of profit. This was too much for the money-greedy Fust. With the Bible printed and ready for sale, he saw his opportunity. He would seize the molds, the type, the presses, and all the printed Bibles. In this way he could get back all, and even more than he had invested. To do this, he brought suit in the court for the return of all the money he had spent on the undertaking. An unjust judge decided in his favor. As Gutenberg had no way of paying such a large sum, Fust seized everything, and turned Gutenberg out.

PRINTING BOOKS IN 1520.

Gutenberg was not, however, to be neglected in his old age. As a reward for his services to the church and to the world, the Archbishop of Mainz made him, in 1465, a gentleman at court, and gave him a pension for life. The pension supplied him with a home, with food, and also with clothing, for the quaint document reads: "We will clothe him every year, always like our noblemen, and give him our court dress."

Gutenberg was not to enjoy his leisure or the honors of a nobleman long. In February, 1468, he became sick and died. He was laid to rest at Mainz.

Honor Paid Gutenberg

Though he died loaded down with debts, and with but few friends by his side, great honors were to come to him as the inventor of the greatest of the modern arts. On one of the first tablets erected to his memory is this inscription: "To John Gutenberg, of Mainz, who, first of all, invented molding letters in brass, and by this art has deserved honor from the whole world." Monuments honoring him are now to be found in many places. His greatest monument will survive them all. It is the printed book.

Samuel F. B. Morse And The Invention Of The Telegraph

Messages are an older means of communication than books or even letters. They must go with the speed of light, sound, or lightning. The American Indians, for example, used at night a system of signal fires, to send messages telling of victories or of danger. In the daytime they held blankets over a fire, so as to signal by means of columns of smoke. Messages were sent also by sound signals made either by the mouth or by a drum. As time went on, a system of signaling by flags and lanterns came into use among more civilized people, such as is now employed by the army and the navy.

The Signal Telegraph

The first practical system of sending messages at all similar to telegraphing, was invented in 1794 by the three Chappe brothers. These three brothers, only boys, were at boarding school. The rules were strict, and did not allow them to visit each other as often as they wanted to. They could see each other from the windows of their rooms so they worked out a way of sending messages. A beam with a small crossbeam at each end was hung on a pivot. The beams and crossbeams could be moved by cords, like the arms of a jumping jack. Each position of the beam and a crossbeam stood for a letter. With this device, it was easy for these boys to spell out messages to each other.

The French government bought the device of the Chappe brothers, building signal stations along the coast, and between Paris and the more important cities. In 1840 there were 1400 miles of signal telegraph. The stations were about three miles apart. The cross-beams of the signal towers were furnished with lights, so that messages could be sent by night as well as by day. An operator could spell out a hundred words an hour.

A system of signaling like that invented by the Chappe brothers was introduced into Russia and England also. There was a line, for example, seventy miles long between London and Portsmouth.

SIGNAL TELEGRAPH OF 1840.

An Englishman wrote in 1828 that the telegraph carried information speedily and distinctly, and that it could be constructed and maintained at little expense.

A similar system was used in America, only large letters were used instead of crossbeams, to spell out the words. Lines were maintained, for example, between New York and Sandy Hook, and between New York and Philadelphia.

The Electric Telegraph

"Take this message as quick as lightning," was doubtless an expression often used in connection with messages. It was not a far step from thinking of taking a message as "quick as lightning," to thinking of making lightning carry the message. Messages were sent by electric telegraph as early as 1774. Every few years after that, some inventor brought forward a new system. Hundreds of men were busy, and in 1838 there were upwards of sixty different systems in the field, each inventor working hard to make his the best.

ELECTRIC-NEEDLE TELEGRAPH.

Steinheil's Electric Telegraph

Oersted learned in 1819, that to make the needle of a compass turn to the left or to the right, all that is necessary is to hold a wire near the compass, parallel with the needle, and send an electric current over the wire toward the north or toward the south. In less than a month afterwards, a French scientist pointed out how this discovery could be used in telegraphing messages.

In 1833, Gauss and Weber, two noted German scientists, put up an electric-needle telegraph line, about a mile long. Wires were stretched around a permanent magnet hung at the center on a silk thread. By changing the direction of the electric current, the magnet was turned, at will, to the right or to the left. One turn of the magnet to the right stood for the letter a. One turn to the left stood for e. Two turns to the right stood for i, and so on. Here is the complete telegraphic alphabet of Gauss and Weber. It has often been used by boys and girls, to signal messages to each other, with their hands and arms.

r=a

rrr=ck

lrl=m

lrrr=w

llrr=4

l=e

rrl=d

lll=n

rrll=z

lllr=5

rr=i

rlr=fv

rrr=p

rlrl=o

llrl=6

rl=o

lrr=g

rrrl=r

rllr=i

lrll=7

lr=u

lll=h

rrlr=s

lrrl=2

rlll=8

ll=b

llr=r

rlrr=t

lrlr=3

llll=9

With this code Gauss and Weber sent all kinds of messages. Being too busy to work on their telegraph, they turned it over to Steinheil. Steinheil built and put into use, at Munich, in 1837, his Registering Electro-Magnetic Telegraph. The line was five miles long. Two permanent magnets were hung in the center of a coil of wire. Each magnet could be made, at will, to swing out from the coil. On an arm fastened to the end of each magnet was a little cup for ink. At the bottom and side of the cup was a printing needle. When the magnet swung out, the printing needle touched a moving ribbon of paper, and printed a dot. Dot signals were thus recorded on the paper in two lines.

Steinheil could send messages at the rate of six words a minute, or three hundred and sixty words an hour. His system was adopted by the Bavarian government, and was in use for many years.

Wheatstone And Cook's Electric Telegraph

Charles Wheatstone, of London, and his business partner also patented, in 1837, an electric-needle telegraph. Five needles were fastened in the center of a diamond-shaped dial, on which the alphabet and numerals were printed. To signal a letter, one needle was turned to the right, and one to the left. The letter signaled was the one at the point where lines running down from the points of the needle crossed. To signal a number only one needle was turned. A line twenty miles long was built, in 1838, on the Great Western Railway. To send messages, it took six wires, one wire to turn each of the five needles, and one to complete the electric circuit, making the system expensive. So Wheatstone invented a two-needle system, and later a single-needle system. From 1838 on, Wheatstone's electric-needle telegraph was in constant use, and for years was the only system which found favor in England.

Morse's Electric Telegraph

Many of the great scientists of Europe thus worked to invent a successful system of electric telegraph. But it remained for an American, Samuel F. B. Morse, to invent the most successful system. Morse's system of electric telegraph was so simple, and messages could be sent by it so quickly, that it drove almost every other system out of business. It is the only system now used in most countries. For this reason, Morse is called the inventor of the electric telegraph, although, strictly speaking, that title does not belong to him. He is, however, the inventor of the most successful system; and for his great service in giving to the world this useful invention, he is worthy of the highest honor.

Morse's Education

Samuel Finley Breese Morse was born in 1791, at Charlestown, Massachusetts. He was given the best education that was to be had at the time. When seven years old he was sent away from home, to a famous private school, Phillips Academy. There he prepared for Yale University, then Yale College, entering with the class of 1807, and completing the course in 1810.

In those days the sciences did not receive much attention at college. In the little that was taught, Morse took an unusual interest. He studied both chemistry and physics, and he learned almost all there was to be known then about electricity and electric batteries. Once Professor Day, his teacher in physics, sent a current of electricity through a chain in a dark room. Flashes of light could be seen between the links. How little Professor Day knew at the time of the influence this experiment was to have! Many years afterwards, Morse said: "The fact that . . . electricity can be made visible at any . . . part of a circuit was the crude seed which took root in my mind, and grew . . . and finally ripened into the invention of the telegraph."

Morse The Artist

Morse, like Fulton, started out to be an artist. At college, he painted miniatures for a number of his classmates. Though he had had no lessons in either drawing or painting, his classmates liked their pictures and paid him a good price for them.

After his graduation from college, Morse decided to study art. Like Fulton, he went to London to work with Benjamin West, where he remained for four years, not returning home until 1815.

He was then twenty-four years old, and up to that time had been supported by his father. He now opened a studio in Boston. Hundreds of people came to see his "Judgment of Jupiter," one of the pictures he had painted in London and which had attracted much attention there. All who came admired it, but no one offered to buy it or order a picture. After waiting a year without receiving a single order, he took again to painting miniatures.

As a wandering artist in Vermont and New Hampshire, he did well. He was even more successful at Charleston, South Carolina, where he went in the winter of 1818. There he had requests for all the portraits he could paint. In a single week one hundred and fifty were ordered, at sixty dollars apiece. He was so successful that in the fall of the first year, he returned to New England, taking his bride back to Charlestown with him. There they lived for three years, saving in that time several thousand dollars. But Morse was not content to remain a portrait painter. He decided to leave Charlestown, and take up what he felt was his true work, the painting of historical pictures. So he moved his family to New Haven, Connecticut.

For eighteen months, he worked early and late on a picture of the House of Representatives. The picture was eleven feet long and seven and a half feet high, with the Representatives on one side, and the Senators on the other. In all, it contained eighty portraits. The picture when finished was exhibited at Boston, but few people took the trouble to see it. No one wanted to buy it, and the whole venture turned out a failure.

Morse soon afterwards removed to New York, and again took to portrait painting. His progress at first was slow. "My cash is almost gone," he wrote to his wife. "I have advertised, and visited, and hinted, and pleaded, and even asked one man to sit, but all to no avail."

Morse was so discouraged that he even thought of going to the city of Mexico. But better days were at hand. General Lafayette was visiting this country, and New York gave Morse an order for a life-size portrait of the Frenchman. For this he received a thousand dollars.

In the midst of his good fortune, Morse was called upon to bear the loss of his wife. Though heartbroken, he went on with his work. He soon had all the portraits he could paint, and came in time to be looked upon as the greatest artist in America. He not only painted portraits, but he gave talks on art, and was the leader in organizing the National Academy of Design.

Still, Morse was not satisfied with his success. To prepare himself to paint the great pictures of which he dreamed,—pictures which he believed would bring fame to himself and honor to his country, he decided to spend three more years in Europe. During these three years, he visited great art galleries and studied the paintings of the great masters.

Planning The Electric Telegraph

In October, 1832, Morse sailed for home on the packet Sully. There was considerable talk among the passengers about electricity. The discoveries of Oersted, Faraday, and Sturgeon were attracting wide attention. Morse was led one day to say: "I see no reason why intelligence may not be sent by electricity." This was a new thought to him. So far as he then knew, no one had ever before thought of sending messages by electricity. The new idea filled his mind. It not only haunted him in the day-time, but it kept him from sleep at night. On leaving the boat he said, "Well, captain, should you hear of the telegraph one of these days, as the wonder of the world, remember that the discovery was made on board the good ship Sully."

Making The First Instrument

Morse was scarcely off the ship, before he was telling his brothers about his new idea. Instead of telling his artist friends about what he saw in the great art galleries of Europe, and about the pictures he had painted, he talked to them, to their disgust, about his electric telegraph. Many people wanted Morse to paint portraits for them, for he was easily the best prepared and the most successful artist in America. But he wanted all the time he could get to work on his invention, and therefore he painted only enough to earn a scanty living. But work as he would, five years passed by before he was even able to complete a working model.

During most of these years he lived in a single room, which served alike for studio, parlor, bedroom, kitchen, and workshop. "In order to save time to carry out my invention," said Morse afterwards, "and to save my scanty means, I had for many months lodged and eaten in my studio, getting my food in small quantities from some grocery, and preparing it myself. To conceal from my friends the stinted way in which I lived, I was in the habit of bringing my food to my room in the evenings, and this was my mode of life for many years."

SAMPLES OF TYPE AND OF WRITING WITH AN IMPROVED TELEGRAPH INSTRUMENT.

Morse was not ready to show his electric telegraph to the public until September, 1837. His telegraphic code was simple. One dot "*" stood for "1". Two dots "**" stood for "2". One dot "*" and a dash "-" stood for "6", and so on for each of the numerals and zero. For each number of the telegraphic code, there was a metal type. There was also a telegraphic dictionary in which given numbers stood for given words. For example, 215 stood for successful.

Morse's first instrument was very crude, and the method of sending and recording messages was slow and clumsy. But to those who for the first time saw messages sent by electric telegraph, the invention seemed wonderful. Besides, Morse had thought of something of which none of the great scientists of Europe had dreamed. In Steinheil's electric telegraph, the signals were recorded by the movement of a magnetic needle. Wheatstone also made use of the magnetic needle. But Morse employed the electromagnet of Sturgeon and of Henry to record the signals in his system, and it was this use of the electromagnet which made the Morse system the most successful of all.

FIRST MORSE INSTRUMENT AND KEY.

Improving The Invention

Up to the time Morse showed his invention to the public in 1837, no one had helped him on it. Being anxious to perfect it, and if possible to get money from Congress to carry out an experiment on a large scale, he now took into partnership Professor Gale, of New York University, who was to work on the electric batteries; and also Alfred Vail, who was to furnish the money needed, and help with the instruments.

During the fall of 1838, the clumsy telegraphic dictionary and code numbers on which Morse had spent many a day was done away with, and a system of dots and dashes for each of the letters of the alphabet and different numbers was planned. This telegraphic code is like the codes of Gauss and Weber, and of Steinheil. It is known the world over as the Morse code:

A *-

H ****

O * *

U **-

B -***

I **

P *****

V ***-

C ** *

J -*-*

Q **-*

W *--

D -**

K -*-

R * **

X *-**

E *

L ---

S ***

Y ** **

F *-*

M--

T-

Z *** *

G --*

N -*

The clumsy way of recording the telegraphic signal by dashes and V-shaped figures was also done away with. The recording instrument was made over, so that it now wrote the dots and dashes which stood for the letters and numbers. In the meantime Professor Gale had so improved the batteries that an electric current could be sent through ten miles of copper wire.

Morse exhibited the improved instrument to his New York friends in January, 1838. "Seeing is believing," but what they saw, they could at first scarcely believe. Message after message, at the rate of ten words a minute, was sent over the ten miles of wire, until the admiration of the company was unbounded. They cheered the inventor and congratulated him on his great invention. Morse received this letter from his brother Sidney: "Your invention, measuring it by the power it will give man to carry out his plans, is not only the greatest invention of this age, but the greatest invention of any age. I see . . . that the surface of the earth will be networked with wire, and every wire will be a nerve, carrying to every part intelligence of what is doing in every other part. . . No limit can be set to the value of the invention!"

Seeking Aid

Morse now took his invention to Washington and asked Congress to give him thirty thousand dollars to build a telegraph line between Washington and Baltimore. This seemed a large sum of money to spend on an untried enterprise. It was also hard for men to understand how useful the telegraph would be. Congress refused to vote the money.

Morse knew that both England and France were spending large sums on their signal-telegraph systems. If they could only see his invention, they would adopt it at once. But he had no money for a trip to Europe. To get it, he took a third partner. The invention was exhibited in London and Paris. Statesmen and scientists came to see it, and Morse was declared a great genius, and was highly honored. Indeed, at one time it seemed as if both France and Russia would adopt his system, but in the end nothing was done. Returning to America in the spring of 1839, he wrote: "I return without a penny in my pocket, and have to borrow even for my meals."

The next four years were the darkest in Morse's life. His partners had spent all their money, and at times lost interest. Congress continued to refuse to vote the thirty thousand dollars. Morse had neglected his art so long that it was hard for him to get pupils to teach, or portraits to paint. Many a morning when he rose, he scarcely knew where the food for the day was to come from.

Once, when a pupil was late in paying for his lessons, he nearly starved.

"Well, my boy," asked Morse, "how are we off for money?"

"Why, professor," replied the student, "I am very sorry to say I have been disappointed; but I expect money next week."

"Next week, I shall be dead by that time."

"Dead, sir?"

"Yes, dead of starvation."

"Would ten dollars be of any service?"

"Ten dollars would save my life; that is all it would do."

The student paid the money, and the two dined together. After the meal was over Morse said, "This is my first meal for twenty-four hours."

These years of delay, though hard to bear, were not lost. With the help of Professor Gale and the advice of Professor Henry, of Princeton, the batteries were improved. So when Congress at last voted the money for the line between Washington and Baltimore, an electric current could be sent through the wires for the entire forty miles. With the help of Mr. Vail, the metal types and the clumsy machine for sending the signals were done away with. A simple finger key was invented to send the dots and dashes. When the metal types were used, only ten words a minute could be sent. With the finger key, an operator could easily send twenty to thirty words a minute. Without these improvements, Morse's electric telegraph would have been a failure when put to the test in 1844.

Morse was tempted many a time to give up. But the thought that his invention marked a new era in history, and would improve the condition of millions of people, kept him from it. In the winter of 1843, he went once more to Washington, seeking the aid of Congress. Columbus himself was scarcely more persevering under discouragement. On the day his bill passed the House of Representatives, Morse wrote to Mr. Vail: "For two years I have labored all my time, and at my own expense, without assistance from the other proprietors, to forward our enterprise. My means to defray my expenses, to meet which every cent I owned in the world was collected, are nearly all gone. If the bill should fail in the Senate, I shall return to New York with the fraction of a dollar in my pocket." "Had the passage of the bill failed," he wrote to a friend, "there would have been little prospect of another attempt on my part to introduce to the world my new invention."

The Bill Passed

On the evening of the last day of the session, Morse sat waiting in the gallery of the Senate. He was told by friendly Senators that there was no chance for his bill to pass, so he finally went to his room. "Knowing from experience whence my help must come in any difficulty," wrote Morse, "I soon disposed of my cares, and slept as quietly as a child."

TELLING MORSE ABOUT THE PASSAGE OF THE BILL.

On coming down to breakfast the next morning, he was met by the daughter of a friend.

"Why this early call?" asked Morse.

"I have come to congratulate you."

"Indeed, for what?"

"On the passage of your bill."

"Oh, no, my young friend, you are mistaken."

"It is you that are mistaken. The bill was passed at midnight."

The news was so unexpected, that Morse for the moment could not speak. Finally he said, "You are the first to tell me, and the first message on the completed line between Washington and Baltimore shall be yours."

In constructing the new line, Morse planned to put the telegraph wires in a lead pipe and then bury the pipe in the ground. After ten miles of lead pipe had been laid, it was discovered that the electric current would not pass through a single mile of it. Twenty thousand of the thirty thousand dollars voted by Congress had been spent. What was to be done? It was decided to place the wires on poles with short crossarms just as you see them to-day. Thinking it was necessary to insulate them, the wires were wrapped in cotton cloth soaked in tar and beeswax, and fastened on door knobs to the crossarms. From now on, the work progressed rapidly. The whole line was finished and opened in May, 1844. Morse remembered his promise, and the young lady selected these noble words: "What hath God wrought!" Of this message Morse said, "It baptized the American telegraph with the name of its Author."

MODERN KEY AND SOUNDER.

Receiving The Reward

It was a favorite idea with Morse that the government should own the telegraph. After it was shown to be a success, he offered to sell it for one hundred thousand dollars. Fortunately for Morse, the government refused the offer, for few inventions have been more quickly and widely adopted. A line was completed, in 1846, between Baltimore and New York. Within the next ten years, telegraph companies sprang up in every section of our country. Most of these combined, and formed, in 1857, a single company, the Western Union. His system was adopted in Canada, then in Europe, and before he died, in 1872, was used in every civilized country of the world. Morse lived, therefore, to see the whole world bound together by the telegraph; each part able to know what was going on in every other part; each part able to communicate and to do business with every other part. Thus, by means of the electric telegraph, the world has been made one in knowledge and one in action.

Alexander Graham Bell And The Invention Of The Telephone

The electric telegraph of Morse was a wonderful invention. A still more wonderful method of sending messages was to be found. There is scarcely a boy or girl old enough to read this book, who has not used the telephone time and time again. So useful is the telephone, that it would now be very difficult for the world to get along without it. Yet it was not invented until 1876. The inventor was Alexander Graham Bell.

Birthplace And Education

Alexander Graham Bell was born at Edinburgh, Scotland, in 1847. He was educated at the Royal High School of Edinburgh, and also attended the University of Edinburgh and the University of London. From boyhood, he was taught at home by his father, about sound and oral speech, and he also received training in music. When he was more than sixty years old, he wrote the following account of his early experiences.

"As I look back and see what points in my early life had an influence on this result, I think that one important element was my love of music. I could play the piano before I could read or write. I could play anything by ear . . . In fact as a little chap I was considered quite a musical prodigy, by a distinguished Italian teacher . . . who, when I was about nine or ten years of age, took me under his charge to make a musician of me, but he did not succeed. Anyway, I had this love of music. I could play all sorts of musical instruments in a sort of a way. I also knew how the different musical instruments were made. I was just as familiar with beating reeds and free reeds, and the way in which the sounds were produced, as a person could be who had really studied the subject.

"A second element was of even greater importance. I came of a family that had made a . . . study of oral speech for two generations before me. My grandfather, Alexander Bell, a distinguished teacher of elocution in London, was the first. Both of his sons,—my father, Alexander Melville Bell, and my uncle, David Charles Bell,—took up the same work. They also . . . devoted their attention to the correction of defects of speech. People who lisped, or stammered, or did anything of that sort, came to my father, to be taught, for example, how to place the organs of speech in forming sounds.

"In my early boyish days, I had the destructive faculty very fully developed. My toys never remained whole in my hands. I would always pull them to pieces to see how they were made, and one of my earliest studies in that respect was plants. I had a delight in puffing plants to pieces to see how they were made. When I was quite a little fellow, I actually took up the study of botany, and I had my collection of plants. My father encouraged me in it. He always encouraged me in making collections of all sorts, and that is a most important thing in the case of a boy. He taught me to observe, compare, and classify. I passed through the stamp-collecting age, the egg age, and the coin age, but the things I took most interest in were the flowers.

"There was another thing which now, as I look back upon it, was of the greatest consequence in its bearing upon the telephone. My father encouraged his boys to study everything relating to the mechanism of speech. We were very much interested in reading of the construction of an automaton speaking machine . . .

"My father proposed to his boys that they should try to make a speaking machine . . . The work was parceled out between my brother Melville and myself. He was to make the lungs and the throat, and the vocal chords, and I was to undertake the mouth . . . I made a mouth modeled from a skull . . . My brother had finished his larynx about the same time that I had made the mouth, and it was a great day when we put the two together. We did not wait for the wind chest that was to represent the lungs . . . but we stuck the thing together. My brother blew through the tube that was to lead from the wind chest, and I took the lips of my machine and moved them. Out came a sound like a Punch and Judy show, and we were delighted when we moved the lips up and down to hear 'Ma-ma! Ma-ma!' distinctly . . .

"My father used the machine to impress upon us the mechanism of speech, but we cared more for the effects produced. I remember very well, one time, when my brother and I took this machine out to the common stairway at Edinburgh . . . My brother blew, and there came a sound like a regular squalling baby, 'Ma-ma! Ma-ma!' in a most distressing tone of voice. Then we were perfectly delighted to hear a door open upstairs and some person come out. When we made it cry for all it was worth, we heard someone say, 'My goodness! What is the matter with the baby?' That was just what we wanted. We crept into our own house softly and shut the door and left our neighbors to look for the baby.

TESTING THEIR TALKING MACHINE ON THE NEIGHBORS.

"There came another period in which I took up what might be termed scientific research . . . Now a controversy arose . . . between my father and myself . . . He had shown that when you whisper vowel sounds you hear musical effects; and when you whisper the vowels in the order in which he had them in his system of Visible Speech, he would . . . hear an ascending scale of musical tones, whereas I as distinctly heard a descending scale . . . To my ear 'E' gave the highest sound and 'Ah' the lowest; to my father's ear 'E' gave the lowest sound and 'Ah' gave the highest. We really had a heated argument over it, until I made the discovery . . . that there were two series of musical tones, one going down and the other going up. My father was convinced that we were both right . . . advised me—I was only sixteen then—to communicate my discovery to a most distinguished man on the subject of phonetics and sound in Great Britain, Alexander Ellis.

"I wrote to him and sent him my analysis of sounds . . . I received a note from Mr. Ellis telling me that I had made a great discovery, but that someone had made it before me. The man who did it was a man by the name of Helmholtz, a great German physicist.

"I went to see Mr. Ellis, and he showed me Helmholtz's book. It was in German and I could not read German, but Mr. Ellis tried to tell me about Helmholtz. He said that . . . Helmholtz had not only analyzed vowel sounds, but had reproduced them by tuning forks . . . set in vibration by an electric current, . . . and I knew nothing of electricity. How I wished I knew how those tuning forks were set in vibration! . . .

"In my ignorance of electricity, I had a curious delusion, and that again had something to do with the telephone. I had the idea, in my ignorance of what Helmholtz had really done, that he had transmitted vowel sounds by electricity; that he had reproduced at the other end of a telegraph line, with those tuning forks, the various vowel sounds. That was my idea. It was all wrong. He never had any such idea, he never did any such thing, but that was my idea, and it occurred to me: 'If Helmholtz could transmit and reproduce vowel sounds, you could reproduce consonant sounds as well; you could reproduce speech.'

"About this time my two brothers died of consumption. As I had overtaxed my own health by overwork—I was teaching by day and studying by night—my father insisted on my stopping all work and going with him to Canada. He bought a farm near Brantford, Ontario, and for some months I lived out of doors."

Teacher Of The Deaf And Dumb

"My father had suggested a use of his system of pictorial symbols representing the position of the vocal organ in forming sounds . . . which caught my fancy . . . He said: 'Here are symbols which have again and again enabled people to pronounce . . . the sounds of a language they have never heard . . . Why, then, might it not be possible through this means to teach the deaf and dumb, who have never heard English, to use their mouths?' I became infatuated with this idea and formed a plan for teaching the deaf and dumb." It was not long before Bell had an opportunity to put his idea into practice. The Board of Education of Boston employed him to teach in the public school for the deaf, and he began his work in April, 1871.

"The teachers in the school for the deaf had been trying to teach the children to speak, and had met with good success. But the teachers made a claim that seemed to me to be ridiculous. They claimed not only that deaf children could be taught to speak . . . but that after they had been taught to speak, they could come to understand speech by looking at the mouth of the speaker . . . I did not dare to say no, but I did not believe it, and out of my skepticism about lip reading grew the telephone."

Bell worked to develop a series of sound pictures, so that deaf children might learn to speak by sight. One of the instruments with which he worked was the phonautograph. The phonautograph used by Bell was a large cone, closed at the small end by a membrane of gold-beater's skin. Hung at one edge of the membrane and attached to the center was a light wooden lever. The other end of the lever extended forward beyond the membrane, and on the end of it was fastened a pig's bristle. Speak into the phonautograph, and the membrane and lever will vibrate, or move back and forth. The vibration of the bristle at the end of the lever traces a zigzag line on a smoked glass drawn underneath. Each sound, "A," "E," etc., has its own vibration or sound picture. Bell's idea was to photograph these sound pictures; then give the deaf child the sound picture of, for example, "A," and put him to work to produce on the phonautograph a sound that would make a similar zigzag line. In this way the child would learn to sound the different letters.

"It struck me," says Bell, "that in the phonautograph, there was a remarkable resemblance to the human ear.

SOUND WAVES MADE WITH HUMAN EAR APPARATUS.

"I went to a distinguished aurist of Boston, and told him I wanted to make a phonautograph, modeling it after the ear. He replied, 'Why don't you use a human ear itself, taken from a dead man, as a phonautograph?' That was quite a new idea, and I said, 'I shall be very glad to do that, but where can I get a dead man's ear?' 'Oh,' he said, 'I will get it for you,' and he did. This was in 1874.

"When my summer vacation came, I ran up to Brantford, Ontario, to spend the time with my parents. I took the human ear with me in order to get tracings. I moistened the membrane with glycerine and water, attached a piece of hay to one of the little bones, and rigged up an apparatus for dragging a piece of smoked glass underneath. Through a speaking trumpet I spoke into that dead man's ear, and obtained beautiful tracings of the vibrations upon smoked glass."

PHONAUTOGRAPH TRACINGS ON SMOKED GLASS.

Birth Of The Telephone

From his study of Helmholtz, Bell thought he saw how to use tuning forks vibrated by an electric current, to send at one time many telegraph messages over one wire. Bell called his invention the multiple or harmonic telegraph. But up to the time he left Brantford for Boston, in April, 1871, the multiple telegraph was merely an idea.

After reaching Boston, Bell was busy instructing teachers how to teach deaf children to talk, and in teaching little deaf children himself. There were many deaf children whose parents were willing to pay almost any sum to have them taught to speak, and Bell was so successful in doing this, that he opened a private school of his own in October, 1872. To this school there came deaf-mutes, teachers of the deaf and dumb, and persons with defective speech.

Bell also took complete charge of the education of a deaf child, George Sanders, and often gave public talks to interest people in the education of the deaf.

In the fall of the next year, Bell went to Salem, Massachusetts, to make his home with the grandmother of his little pupil, George Sanders. In the attic of his new home he fixed up a workroom. This was supplied with tuning forks, reeds, magnets, electric batteries, wire, and the like. His days were spent in Boston at his school, but many an evening found him in his attic workshop, busy with his multiple telegraph.

TALKING IN FIRST FORM OF TELEPHONE.

"Often in the middle of the night Bell would wake me up," said Thomas Sanders, the father of George. "His black eyes would be blazing with excitement. Leaving me to go up to the attic, he would rush wildly to the barn and begin to send me signals along his experimental line. If I noticed any improvement in his machine, he would be delighted. He would leap and whirl around in one of his 'war dances,' and then go contentedly to bed. But if the experiment was a failure, he would go back to his bench and try some different plan."

When Bell arrived at Brantford, in the summer of 1874, he was thus carrying on two studies. He was working on his multiple telegraph, and he was trying to make tracings of the vibrations of sounds so as to get sound pictures to use in teaching the deaf.

Bell had with him, as has been said, a phonautograph made from a dead man's ear. "As I was holding the human ear in my hand, it struck me," says Bell, "that the bones of that human ear were very massive compared to the membrane. The membrane was like a little piece of tissue paper, hardly the size of a finger nail, and the bones that were moved by the little membrane were really very heavy. It suddenly occurred to me, that if such a small membrane as that would move bones so massive in comparison, why would not a larger membrane move my piece of iron? At once the idea of a membrane speaking telephone became complete in my mind. All I had to do was to attach a steel reed, not tuned to any definite pitch, to the center of a stretched membrane, just as in the phonautograph, so that it would vibrate in front of an electromagnet, and put another at the end of a telegraph wire, and we would have . . . a speaking telephone."

The idea of a membrane electric-speaking telephone was thus complete in Bell's mind in the summer of 1874. But he did not try to make one, for he felt it would not work. On his return to Boston, in the fall of 1874, Bell succeeded in interesting Thomas Sanders and Gardner Hubbard in his ideas. Sanders was the father of George Sanders, the little boy who was being instructed by Bell, and Hubbard was the father of Mabel Hubbard, also one of his pupils. Sanders and Hubbard promised to pay the cost of Bell's experiments. But he gave his time chiefly to the multiple telegraph, because they thought this invention would be more profitable than the telephone.

The next year was full of work. Bell toiled day and night, making experiment after experiment. Such was the progress on the multiple telegraph, that an application for a patent was made in February, 1875, for "Improvement in Transmitting Telegraph Messages." The patent was granted in April, 1875. Like so many other patents, nothing ever came of the multiple telegraph, though Bell worked on it for some years to come.

Making The First Telephone

Bell's hard work on the multiple telegraph told on his courage. At one time he was about ready to give up trying to invent a telephone, but was encouraged to go on by the same great man who helped Morse, Professor Henry. Bell visited Henry, to consult with him about some experiments connected with the multiple telegraph. "I felt so much encouraged by his interest," wrote Bell to his parents, "that I decided to ask his advice about the apparatus I have designed for the transmission of the human voice. I explained the idea and said: 'What would you advise me to do, publish it and let others work it out, or attempt to solve the problem myself?' He said he thought it was 'the germ of a great invention,' and advised me to work at it myself . . . I added that I felt that I had not the electrical knowledge necessary to overcome the difficulties. His laconic answer was 'Get it.'

"I cannot tell you how much these two words have encouraged me . . . Such an idea as telegraphing vocal sounds would . . . to most minds seem scarcely feasible enough to spend time in working over. I believe . . . that it is feasible, and that I have the clue to the solution of the problem."

If Bell did not have the "clue," when writing to his parents, it was discovered by accident in June, 1875. On this eventful day in the history of the telephone, Bell and his assistant, Mr. Watson, were at work trying to send three messages at one time over one wire. Watson was in one room, and Bell in another. Each had three instruments. Each instrument was composed of an electromagnet and a vibrating steel used for an armature.

Bell completed the electric circuit connecting the instruments, and plucked the reed of instrument A. "I asked Watson," said Bell afterwards, "whether his instrument A responded. He said: 'No; the armature of A sticks to the magnet . . . 'I called to him to pluck it loose. It so happened that I had my eyes upon my instrument A, and when he plucked it loose, I saw the armature of my instrument A get into vigorous vibration. I thought that was strange, so I called to Watson, 'Pluck it again.' . . . Well, we did not do anything all that day but pluck reeds . . . Why did we pluck those reeds all that day? It was proof that the wave-like current produced by the vibration of an armature in front of an electromagnet was powerful enough to produce practical effects. The telephone I had had in mind since the summer of 1874 was really a practical thing. I instantly gave instructions to have the first telephone made."

ORIGINAL BOX TELEPHONE.

June was a busy and feverish month for both Watson and Bell. Everything about a membrane electric-speaking telephone had to be learned. Experiments were made to find out whether the best results could be obtained with permanent magnets at each end of the line or with electro-magnets. Tests were made with armatures of different thickness and size. Different ways were tried of fastening the armature to goldbeater's skin, which was used for the membrane. The different parts were put together now in this way and now in that way. At least two unsuccessful instruments were made. Finally the third instrument was ready for trial. The same instrument was used both as a transmitter and as a receiver. That is, one would speak into the instrument and then place his ear to it to hear what was said in reply.

The trial was made in a noisy electrical workshop. Bell was upstairs with one instrument, and Watson was downstairs with another; the two instruments were connected in an electric circuit. Of this trial Bell says: "I spoke, and shouted, and sang into the instrument upstairs. Presently Mr. Watson came upstairs in a state of great excitement. He said: 'I hear your voice; I could almost understand what you said!' I said: 'Try for me.' He tried for me, but I could not hear him. There was no doubt about it, that he could hear something that I said, but I could not very well make out what he said . . . I could account for the trouble. In the first place, we were in a noisy workshop. My ears, not being accustomed to that noisy workshop, were not so good as his. I was an elocutionist and knew how to throw out my voice; he was a mechanic who did not know. So I could speak better than he could, while he could hear better than I could. I had faith that the instruments were all right, and it turned out that they were. We tried the instruments in a quiet place and they worked all right."

Exhibiting The Telephone

Bell was granted a patent on his telephone on March 6, 1876. He was then twenty-nine years of age, and the possessor of what turned out to be the "most valuable single patent ever granted."

Mr. Hubbard, Bell's friend and future father-in-law, had charge of the educational exhibit of the Centennial Exposition, in 1876. He persuaded Bell to exhibit his multiple telegraph and telephone. The telephone transmitter,—the part one speaks into,—which Bell sent to Philadelphia, was made like the transmitter he and Watson had used in their trial of July, 1875. But the form had been changed so that one could speak into the tube with greater ease, and could more easily throw the voice directly against the membrane. They had also learned by experience, that one could understand better what was said, if a different instrument was used as a receiver,—the part that is held to the ear. So Bell made what came to be known as the iron-box receiver; one of these was also sent to Philadelphia. In the iron-box receiver, instead of employing goldbeater's skin for the membrane, as was done in the transmitter, a thin circular piece of iron was used. With the iron-box receiver, it was easy to hear what was said at some little distance from the instrument.

Bell's telephone instruments were at the Centennial a month, but no one paid much attention to them. Then of a sudden the telephone became the most talked-of article at the great exhibition. The wonderful change came about in this way.

BELL'S CENTENNIAL RECEIVER.

On Sunday, June 25, the electrical instruments were to be shown to the judges. Dom Pedro, Emperor of Brazil, Sir William Thompson, the greatest electrical scientist at that time in the world, and other famous people were to be there. Mr. Hubbard was anxious that Bell should go to Philadelphia and exhibit his instruments himself, but Bell, because of his school work, refused to go.

"Then Mr. Hubbard took an unfair advantage of me," says Bell. "He appealed to a certain young lady to see what she could do to influence me." (The young lady was none other than Mabel Hubbard, whom Bell married a year later.) "I told her that, of course, I would be glad to go, but that it was impossible; that it was right in the midst of my examinations, and it would not be fair to my pupils. She said, 'Well, won't you come down to the station with me?' 'Yes, I will go down to the station, but you need not try to persuade me, as I cannot go.' So we went down to the station and walked up and down the platform. When the train was going off, and when she saw that I was really not going, she too used an unfair advantage. Who can bear to see a young girl weep? I just jumped on that train. I did not have any baggage or anything else. So, growling like a bear, I went to Philadelphia . . .

"On Sunday I went out to the exhibition. There were a whole lot of electrical exhibits to be shown, . . . and the poor judges were trotted around to see one thing after another until they were fairly ready to drop. I followed the judges around, while they looked at this thing and that thing. They came finally to an exhibit of Elisha Gray, who had a machine for transmitting musical tones like my multiple telegraph. He gave a very interesting talk. It was very interesting to me, because I came next, and he kept on and kept on, until at last, when he got through, the chairman of the judges said they would postpone the further examination of electrical apparatus to another day. That meant that they would never see the telephone . . . I could only stay that Sunday, and I felt that my whole exhibit was cut out. The judges began to disperse, when suddenly Emperor Dom Pedro saw me, and recognized me as the young man whom he had met in Boston, when he visited the school for the deaf and dumb. He came up to me and said, 'Mr. Bell, how are the deaf-mutes in Boston?' I told him they were very well, and that my exhibit was the next. He said he must go to see it, took my arm and walked off with me, and of course the judges followed like a flock of sheep. My exhibit was saved."

DOM PEDRO AND THE TELEPHONE.

The instruments were ready for use. Dom Pedro took a seat at a table on which rested the little iron-box receiver, and was asked to hold his ear near the top of the strange little instrument. Bell sat down in another room and spoke slowly and with great distinctness into the tube of the transmitter. Dom Pedro, of course, did not know what to expect, nor did anyone else in the room. Suddenly the Emperor raised his head and with a look of utter amazement on his face exclaimed, "It talks!" Then came Sir William Thompson, who knew so much about electricity; he listened, and listened, and listened to that little iron disk talk with a human voice. Then with great emphasis said, "It does speak. It is the most wonderful thing I have seen in America . . . It is the greatest marvel hitherto achieved by the electric telegraph . . . Before long, friends will whisper their secrets over the electric wire!"

MODERN TELEPHONE.

When Sir William Thompson spoke, the world believed.

"I went to bed the night before," said Bell, "an unknown man, and awoke to find myself famous. I owe it to Sir William Thompson, back of him to Dom Pedro, and back of him to the deaf-mutes of Boston."

Thomas A. Edison

Edison, "The Wizard of Menlo Park," as he is called, is our best-known living inventor. As a boy, his curiosity and daring led him into unusual adventures, and of his boyhood days many and interesting stories are told: How he pulled an old duck off her nest and sat on the eggs himself to see if he could hatch them; how he set fire to a barn, and was publicly whipped for it in the village square; how he tried to read all the books in the public library, and actually read all on a seven-foot shelf; how he set fire, when a newsboy, to a car, and was boxed on the ear by the train conductor, making him deaf for life; how he saved the life of an operator's son, and was taught telegraphy by the operator. These stories may be read in any life of Edison.

Edison has taken out about fourteen hundred patents in the United States alone. He has not made all of these inventions himself. He worked like other inventors in his early days, doing all the work himself on whatever he had in hand, but for many years he has conducted a great factory, in which hundreds of men are employed, all busy on inventions. Just as other men conduct factories to manufacture, for example, automobiles, Edison conducts his factory to work out inventions. Most of the inventions attributed to him are, therefore, the product of his factory, rather than of himself alone.

OPERATOR TEACHING YOUNG EDISON TELEGRAPHY.

The first patent taken out by Edison was in 1869, on a vote-recording machine. The machine was designed to secure privacy in voting, and to prevent fraud in public elections. The politicians did not want any such machine to come into general use, and the voters were not ready for it, so his first invention proved a flat failure. Edison, however, gained a valuable lesson from this experience. He resolved never to make an invention which was not wanted, and which could not be made a commercial success. From that day to this, before he undertakes an invention, he studies with great care the possible demand for it, the cost of making the invention, and the probable profits from its manufacture and sale. To this method of work is due much of his commercial success. But no small part of it is due to his industry and to his courage. He works as hard as any of the men he employs, often toiling for long periods, eighteen out of the twenty-four hours of the day. Then, too, it requires courage to invest great sums of money in new and untried things. The fine courage which sustained him during all these years was well illustrated when a great fire destroyed a number of his factory buildings. His answer to the wild flames as they leaped upon and ate up building after building was, "We will begin rebuilding to-morrow."

Of all Edison's inventions, in some ways the most valuable are his electric light, his phonograph, and his moving picture.

EDISON'S FAMOUS HORSESHOE PAPER-FILAMENT LAMP, 1870.

When Edison first exhibited his talking machine, in 1877, people hearing it repeat "Mary had a little lamb" deemed it a greater invention even than the telephone, and crowds filled great halls to hear the wonderful machine. The story went about at the time, that Edison gained the idea of the phonograph from accidentally pricking his finger. This is, of course, not true. The talking machine was the product of careful thought and hard work.

PHONOGRAPH DEVELOPED FROM THE FIRST INSTRUMENT.

Edison first began to think of reproducing sounds mechanically, from reflecting on the record made on a disk by a needle attached to a telegraph key. From working with a phonautograph, the instrument used by Bell to record sound waves on a smoked paper, he conceived the idea of recording sounds on tin foil or on a wax disk, and then sending the needle back over the grooves to reproduce the sounds.

A phonograph is really only a phonautograph developed. The sounds to be reproduced are first recorded in grooves on a wax disk, by means of a phonautograph with a needle attached to the diaphragm. To reproduce the sounds thus recorded, the needle of the phonautograph is sent back over the grooves in the disk, and the sounds produced by the vibrating diaphragm are magnified by a horn-like arrangement. The phonograph is therefore a very simple mechanical contrivance to reproduce sound. It is, nevertheless, one of the most popular of modern inventions, as it has brought the music of the masters within the reach of the home, at small cost.

A MOVING-PICTURE MACHINE.

The moving picture, on the other hand, has done in part for the eye what the phonograph has done for the ear. As with some other great inventions, a popular toy was the forerunner of the moving picture. Some twenty years or more ago, it was possible to buy pictures of boys, in different positions, on a strip of paper stretched over a circular framework. By turning the crank the pictures were whirled around, making the boys appear to be playing leapfrog.

The first real moving pictures were of animals taken in motion. In working with these animal pictures, it was discovered that if they were passed before the eye at the rate of sixteen a second, instead of seeing sixteen pictures of the same animal in different positions, the animal appears to be moving. The moving picture is therefore nothing more than a number of pictures of the same object, animal, or person, in different positions, passed rapidly before the eye. The common rate of taking the pictures and of exhibiting them is sixteen per second. Edison took advantage of this peculiarity of our sight. He perfected the process of taking pictures of objects in motion, discovered the best materials for films, and worked out other practical details essential to good moving pictures. Few towns are now too small to have their "movies." Probably no invention is more popular, and surely none contributes more to the amusement of the public.

FIRST MOTION PICTURE OF AN OPENING FLOWER.

Edison, however, is to be thought of not only as an inventor, but also as a business man. Around and about his many inventions have grown great business enterprises, of which he is part owner. In these different enterprises are invested a total of almost seven billions of dollars, and in them are employed three quarters of a million men. To have set in motion such gigantic business enterprises, to say nothing of his great contributions to the comfort, pleasure, and amusement of nations, is in itself enough to rank Edison among the most distinguished of Americans.

Orville And Wilbur Wright

People have always had a desire to fly. There is an old Greek story of Daedalus, who made wings of wax, with which he and his son Icarus tried to fly over the sea. Daedalus told Icarus not to go near the sun, lest his wings should melt. Icarus was a knowing youth. He ventured too near the sun, his wax wings melted and dropped off, and he fell into the sea and was drowned.

There is also the familiar story of an American boy, named Darius Green, who tried to fly. Said Darius to himself:

"The birds can fly an' why can't I?

Must we give in," says he with a grin,

"That the bluebird an' phoebe

Are smarter'n we be?

Jest fold our hands an' see the swaller

An' blackbird an' catbird beat us holler?

Does the little chatterin', sassy wren,

No bigger'n my thumb, know more than men?

Jest show me that!

Ur prove 't the bat

Hez got more brains than's in my hat,

An' I'll back down, an' not till then!

"That Icarus

Made a perty muss—

Him an' his daddy Daedalus

They might 'a' knowed wings made o' wax

Wouldn't stand sun-heat an' hard whacks.

I'll make mine o' luther,

Or suthin' ur other."

Darius was, however, no more successful than Icarus of old, though he did escape the fate of Icarus, falling in his father's barnyard.

The first man who tried seriously to learn how to fly was a German named Lilienthal. He built a wing-shaped machine. With this fastened securely under his arms, he would make a running start and glide from the top of high hills or tall buildings. He thus worked for five years, studying how to master air currents and the difficulties of flight; but he never succeeded in floating more than a few minutes at a time. One day, when floating about fifty feet from the ground, his queer machine was caught by a sudden gust of wind, which hurled it to the ground, killing Lilienthal.

LILIENTHAL'S WING SHAPED GLIDER.

Another pioneer of aerial flight was an American, Professor Langley, of the Smithsonian Institution. Although he gave the latter years of his life to the study of this subject, and actually constructed a power-driven machine, he never succeeded in flying more than three quarters of a mile at any one time.

LANGLEY'S STEAM MODEL.

Professor Langley's experiments, however, attracted much attention, and French and English scientists with the finest technical training began to work on the problem of aerial navigation. But the first to succeed in flying in a heavier-than-air, power-driven machine were two American young men, with only a high school education, with no scientific training, and with very little money to carry on their work,—the Wright brothers, Orville and Wilbur.

The Wright brothers were born at Dayton, Ohio. They were always interested in mechanical things, and owned and conducted a successful shop for the repair of bicycles. Their attention was first called to the flying machine by reading, in 1896, of the death of Lilienthal. They began to work on a flying machine as a mere matter of sport.

THE FIRST WRIGHT GLIDER.

They had no money to spend on experiments, nor did they care to risk their lives in trying to fly before they knew how. Accordingly they spent much time in watching birds fly, and in discussing the principles of flight. They read all the books they could find on the subject, and studied all the different flying machines that had been made.

THE SECOND WRIGHT GLIDER.

The first flying craft constructed by the Wright brothers—and they always made their own machines—was a glider, which they flew like a kite. It was controlled by levers worked from the ground by ropes. They were thus able to study the principles of flight, and how to control a flying machine suspended in the air.

Their next machine was a man-carrying glider, which they used, much as Lilienthal had done, to glide in the air from high hills. It was easy enough to glide along on the air, but it was very difficult to balance the glider and to control its course. In order to experiment safely, they went in 1900 to a secluded place in North Carolina, where there were high sand hills which offered good opportunities for gliding, and a soft place on which to light, should they fall. During the next two years, they made about a thousand gliding flights, some of these as much as six hundred feet long.

THE WRIGHT AIRSHIP IN FLIGHT.

Their next step was to find a way to propel the glider. During 1903 they were busy on a suitable gasoline motor, but it was not until December that they were ready for their first attempt to fly in a motor-propelled machine. For the trial trip, they went again to the secluded place in North Carolina. The brothers were confident that their machine would fly, but they made no predictions, and had little to say.

"The first flight lasted only twelve seconds, a flight very modest compared with that of birds, but it was, nevertheless, the first in the history of the world, in which a machine carrying a man had raised itself by its own power into the air in free flight, had sailed forward on a level course without reduction of speed, and had finally landed without being wrecked. The second and third flights (the same day) were a little longer, and the fourth lasted fifty-nine seconds, covering a distance of eight hundred and thirty-five feet over the ground against a twenty-mile wind."

What had started as a sport, thus developed with the Wright brothers into a serious scientific study. By 1905, they had so mastered the motor that they were able to make a flight of twenty-four miles, at the rate of thirty-five miles an hour. Up to this time they had worked in comparative quiet, and without being written up in the newspapers and magazines. But their long flights now began to attract the attention of the world.

THE WRIGHT AEROPLANE.

In 1908, Wilbur took a machine to France. The French newspapers printed cartoons of him, with a long neck, a beak, and talons for fingers; they also made fun of his shabby-looking machine. Nevertheless, this same Wilbur was not long in breaking the world's record, with a flight of fifty-two miles, being in the air ninety-one minutes. A few days later he won a prize of twenty thousand francs. In addition to this, the French government soon afterwards gave the Wrights an order for thirty machines.

At the very time that Wilbur was breaking world records and winning prizes in France, Orville was making famous flights at Fort Myer, Virginia, flying for more than an hour at a time, and repeatedly ascending with a passenger.

NC-4 AMERICAN AIRPLANE, FIRST TO CROSS THE ATLANTIC.

The summer of 1909 witnessed the greatest triumphs in aerial navigation. Bleriot, a Frenchman, crossed the English Channel in his monoplane. Soon afterwards, Zeppelin sailed two hundred and twenty miles in his dirigible balloon, and Orville Wright carried a passenger from Fort Myer to a point in North Carolina. An American airplane, the NC-4, was the first flyer to cross the ocean, in 1919. The English dirigible R-34 accomplished a like feat a few weeks later.

Air craft are now a regular part of the equipment of all armies, and airmen are able to perform almost unbelievable feats as army scouts.

ENGLISH DIRIGIBLE R-34, THE FIRST TO CROSS THE ATLANTIC.

There is something thrilling about riding in a flying machine and making a highway of the air. But the first successful air craft was perfected, as we have seen, by the Wright Brothers, two unromantic Americans who never allowed themselves to be carried away by their enthusiasm. They never talked about themselves or boasted about what they were going to do. They avoided notoriety and claimed no genius for themselves, yet their silent and persistent work counted in the end, and they are sure of a place of honor in the history of aerial navigation.

Guglielmo Marconi

On January 23, 1909, the world suddenly discovered that a wonderful, new, and practical invention had come into use. At daybreak of that day the passenger steamer Republic  collided with the Florida, off the coast of Nantucket Island. The Republic sent out this message: "We were struck by an unknown boat; engine room filled; passengers all safe; can stay afloat." Instantly the message was caught by the Baltic, the Lorraine, and by two United States revenue cutters, and all sent their promise to help. The Baltic  arrived beside the Republic  first, and saved the lives of sixteen hundred passengers.

But how could a vessel far out in the ocean send a message? By wireless telegraphy, perfected by Guglielmo Marconi. Only eight years before this collision between the Republic  and the Florida, Marconi and an assistant sat at a table in a bare room in the Old Barracks at Signal Hill, Newfoundland. By the side of Marconi hung a telephone receiver connected with a wire which ran out of the window to a kite, floating four hundred feet over-head. Two thousand miles away, on the coast of Cornwall, England, there sat another man at the foot of a mast two hundred and ten feet high, with a wire hanging down from it connected with an electric battery and a telegraph key.

Marconi cabled to Cornwall that all was ready, then he listened, with the telephone receiver to his ear, for more than a half hour before he heard the first click. There were three of these, meaning "S," the signal he had agreed upon with the man at Cornwall. More signals came, and he listened again and again to make sure. This was the first wireless message over the ocean, and Marconi knew that his invention, upon which he had worked for years, could be made a success.

Marconi is an Italian. He received a splendid scientific training in the schools of Florence and Bologna, and showed an interest in electricity from the time he was twelve years old. One day, when he was about twenty-one, while sending electric waves through the air and getting signals a mile away, he accidentally noticed that an instrument on the opposite side of a hill from the sending instrument was affected. The only way this instrument could be affected was by the electric waves passing through the hill. "If electric waves will pass through a hill, they can be made," he said to himself, "to pass long distances over the land and even over the ocean, and it will be possible to telegraph without wires." Thus was born the idea of the wireless telegraph.

A WIRELESS OPERATOR.

Every boy knows that a stone dropped into a pond starts waves in all directions, and although the water only moves up and down, the waves go on and on, until they reach the shore of the pond or have spent their force. In like manner, when a current of electricity is discharged into the air, electric waves go out in all directions and keep on going until their force is spent.

In addition to a code—and the regular telegraph code is used—there is only needed, then, to send a wireless message, an instrument to produce the electric waves, or a transmitter; and an instrument to collect these waves, or a receiver. The cr-a-ck, cr-a-ck of the sparks when the electric currents leap between the knobs of the transmitter is a familiar sound. The crack of these sparks at long distance stations is like thunder, and the flame is as large around as a man's wrist.

WIRELESS STATION AT WELLFLEET, MASSACHUSETTS.

In the construction of instruments for a wireless telegraph station, the receiver is much harder to make than the transmitter. The most important parts are the coherer, which catches the electric waves, and the decoherer, which makes and breaks the current, producing sounds corresponding to the dots and dashes of the Morse key. Receivers are now so tuned or harmonized that they will receive electric waves only from a particular transmitter. In this way, messages can be sent as secretly by wireless as by the ordinary telegraph. There are, however, signals which all receivers will catch, like the S.O.S., used by the wireless to call for help.

Even before the sinking of the Titanic, most ships were provided with wireless. Since then, all vessels sailing from American ports, and carrying fifty passengers or more, are required by law to be provided with a wireless outfit. The wireless has added greatly to the safety of the ocean; and it is extensively employed in war. At no distant date, messages will doubtless be sent without relay around the world, and it is not impossible that we may live to see the wireless of Marconi displace the older telegraph of Morse.

John P. Holland and The Submarine

You will remember that Robert Fulton experimented for a long time on a submarine or plunging boat. He believed that his diving boat, the Nautilus, with the aid of torpedoes, would make war vessels useless, and so do away with every kind of warfare on the seas. He failed in turn to interest either the French, the English, or the United States government in his project, or his boat.

Who first thought of an under-sea boat, nobody knows. It certainly was not Fulton, for David Bushnell was floating about New York Bay in the days of the Revolutionary War, in his primitive submarine, the Turtle. This boat, so-called from its resemblance to a turtle, floating tail downward and with a conning tower for a head, was literally a one-man boat. Two "oars" or "screws" worked from the inside by a crank propelled it, and the operator directed its course by means of a rod attached to the rudder, which he held under his arm.

This absurd little submarine, however, came near blowing up the British frigate Eagle, as she lay at anchor with her guns trained on Manhattan Island. On the after deck of the Turtle were two hollowed-out pieces of oak filled with gunpowder, arranged to explode, after the operator had bored a hole in the frigate, had deposited his crude torpedoes, and was far enough away to be out of range. But the Eagle was copper sheathed, and it was impossible to bore into the hull. Two other attempts were made to blow up British ships with the aid of Bushnell's boat, but both failed. The boat finally came to a sad end, when a sloop carrying her, sank, submarine and all. We have David Bushnell to thank, however, for the idea of the conning tower and the propeller, and the actual beginnings of the torpedo.

The Civil War aroused new interest in the submarine. The Hundley, operating in Charleston harbor, actually torpedoed and sank the Housatonic, but the rush of water from the exploding torpedo sank the Hundley  with all her crew. So the first victim of the submarine, and the first under-sea boat to sink a warship prior to 1914, lay side by side at the bottom of the sea.

The first man to succeed in making a practicable submarine was John P. Holland, who was born in Ireland in the year 1842.

Holland was busy on an under-sea boat in 1862. On coming to Paterson, New Jersey, in 1873, where he became a teacher, he continued to work away at his plan after school hours. He built altogether seven submarines, none of which amounted to much. Finally, in 1898, he launched the Holland No. 8. This was a porpoise-like craft, fifty-three feet long and ten feet wide, with a single torpedo tube. It plunged head on, like a duck, when water was let into specially arranged compartments, and it rose to the surface when the water was driven out by compressed air,—all in five seconds. It could be held at any desired depth under water, where it moved about like a fish. When afloat it had a speed of eight miles an hour, and a cruising radius of 1500 miles. After seeing the Holland, Admiral Dewey said, "If they (the Spaniards) had had two of these things at Manila, I could not have held it."

Within the next few years Holland sold plans for submarines to the United States, England, Japan, and Germany.

SECTION OF THE HOLLAND SUBMARINE OF 1901.

The submarines in use at present are often 200 to 300 feet long, with crews of from twenty-five to eighty men. They cross and recross the Atlantic Ocean with ease. The Deutschland brought over the first cargo of freight from Europe, landing at Baltimore in 1916.

When afloat, heavy oil-burning engines drive the submarine along at a rate of twenty to thirty miles an hour. When submerged, electricity is used, as it makes less heat and throws off fewer odors to pollute the air, which has to be safeguarded, lest the crew suffocate. A submarine can remain under water twenty-four hours at a time, but to be comfortable for the crew, it needs to come to the surface five or six times a day, to pump in a supply of fresh air.

Submarines no longer dive straight down. After everything is shut tight to keep out the water, the bow of the submarine is tipped slightly, and the boat glides gently down to the desired depth. Fifty feet is the ordinary depth, but they can dive to a depth of two hundred feet. Submerging is more or less dangerous, however, and frightful accidents have occurred. Something may go wrong with the machinery. Or if they dive too deep the great pressure of the sea may crush the hull. Or, as happened with the American F-4, when the entire crew was lost, acids from the electric batteries may eat away the rivets so that the hull may cave in.

The latest submarines have both eyes and ears. The eye is the periscope, so necessary to submergence. The periscope consists of a system of mirrors inside a tube, which is extended, when the boat is submerged, to a distance of fifteen to twenty feet above the surface of the water. By looking into the mirror at the bottom of the periscope, the captain sees everything that happens above. The periscope thus enables the submarine to locate ships, and to aim its deadly torpedoes without unnecessary exposure.

PERISCOPE OF A SUBMARINE.

When afloat, a wireless outfit serves for ears. But submarines can also hear when under water. A steel disk, eighteen to twenty inches in diameter, is attached to the hull, and this disk by means of an electric current acts as an under-sea wireless. The steel ear has still another use. The engines of vessels in motion make considerable noise. This is carried through the water and vibrates the submarine's ear. After a little practice it is easy for the listener to tell the direction from which the noise comes, and the locality of the ship.

Submarines now carry both torpedoes and cannon. When it is safe for the submarine to be afloat, the vessel to be destroyed is more likely to be shelled by cannon and afterwards torpedoed at short range.

The submarine is thus a monster that dives, and floats, and moves with animal-like quickness; that sees, and hears, and has mile-long-arms of more than giant strength.
