"What are you bothering yourselves with a knitting machine for?" asked Ari Davis, of Boston, a manufacturer of instruments; "why don't you make a sewing-machine?" His advice had been sought by a rich man and an inventor who had reached their wits' ends in the vain attempt to produce a device for knitting woolen goods. "I wish I could, but it can't be done." "Oh, yes it can," said Davis; "I can make one myself." "Well," the capitalist replied, "you do it, and I'll insure you an independent fortune." The words of Davis were uttered in a spirit of jest, but the novel idea found lodgment in the mind of one of the workmen who stood by, a mere youth of twenty, who was thought not capable of a serious idea.

But Elias Howe was not so rattle-headed as he seemed, and the more he reflected, the more desirable such a machine appeared to him. Four years passed, and with a wife and three children to support in a great city on a salary of nine dollars a week, the light-hearted boy had become a thoughtful, plodding man. The thought of the sewing-machine haunted him night and day, and he finally resolved to produce one.

After months wasted in the effort to work a needle pointed at both ends, with the eye in the middle, that should pass up and down through the cloth, suddenly the thought flashed through his mind that another stitch must be possible, and with almost insane devotion he worked night and day, until he had made a rough model of wood and wire that convinced him of ultimate success. In his mind's eye he saw his idea, but his own funds and those of his father, who had aided him more or less, were insufficient to embody it in a working machine. But help came from an old schoolmate, George Fisher, a coal and wood merchant of Cambridge. He agreed to board Elias and his family and furnish five hundred dollars, for which he was to have one-half of the patent, if the machine proved to be worth patenting. In May, 1845, the machine was completed, and in July Elias Howe sewed all the seams of two suits of woolen clothes, one for Mr. Fisher and the other for himself. The sewing outlasted the cloth. This machine, which is still preserved, will sew three hundred stitches a minute, and is considered more nearly perfect than any other prominent invention at its first trial. There is not one of the millions of sewing-machines now in use that does not contain some of the essential principles of this first attempt.

When it was decided to try and elevate Chicago out of the mud by raising its immense blocks up to grade, the young son of a poor mechanic, named George M. Pullman, appeared on the scene, and put in a bid for the great undertaking, and the contract was awarded to him. He not only raised the blocks, but did it in such a way that business within them was scarcely interrupted. All this time he was revolving in his mind his pet project of building a "sleeping car" which would be adopted on all railroads. He fitted up two old cars on the Chicago and Alton road with berths, and soon found they would be in demand. He then went to work on the principle that the more luxurious his cars were, the greater would be the demand for them. After spending three years in Colorado gold mines, he returned and built two cars which cost $18,000 each. Everybody laughed at "Pullman's folly." But Pullman believed that whatever relieved the tediousness of long trips would meet with speedy approval, and he had faith enough in his idea to risk his all in it.

Pullman was a great believer in the commercial value of beauty. The wonderful town which he built and which bears his name, as well as his magnificent cars, is an example of his belief in this principle. He counts it a good investment to surround his employees with comforts and beauty and good sanitary conditions, and so the town of Pullman is a model of cleanliness, order, and comfort.

It has ever been the man with an idea, which he puts into practical effect, who has changed the face of Christendom. The germ idea of the steam engine can be seen in the writings of the Greek philosophers, but it was not developed until more than two thousand years later.

It was an English blacksmith, Newcomen, with no opportunities, who in the seventeenth century conceived the idea of moving a piston by the elastic force of steam; but his engine consumed thirty pounds of coal in producing one horse power. The perfection of the modern engine is largely due to James Watt, a poor, uneducated Scotch boy, who at fifteen walked the streets of London in a vain search for work. A professor in the Glasgow University gave him the use of a room to work in, and while waiting for jobs he experimented with old vials for steam reservoirs and hollow canes for pipes, for he could not bear to waste a moment. He improved Newcomen's engine by cutting off the steam after the piston had completed a quarter or a third of its stroke, and letting the steam already in the chamber expand and drive the piston the remaining distance. This saved nearly three-fourths of the steam. Watt suffered from pinching poverty and hardships which would have disheartened ordinary men; but he was terribly in earnest, and his brave wife Margaret begged him not to mind her inconvenience, nor be discouraged. "If the engine will not work," she wrote him while struggling in London, "something else will. Never despair."

"I had gone to take a walk," said Watt, "on a fine Sabbath afternoon, and had passed the old washing-house, thinking upon the engine at the time, when the idea came into my head that, as steam is an elastic body, it would rush into a vacuum, and if a communication were made between the cylinder and an exhausted vessel, it would rush into it, and might be there condensed without cooling the cylinder." The idea was simple, but in it lay the germ of the first steam engine of much practical value. Sir James Mackintosh places this poor Scotch boy who began with only an idea "at the head of all inventors in all ages and all nations."

See George Stephenson, working in the coal pits for sixpence a day, patching the clothes and mending the boots of his fellow-workmen at night, to earn a little money to attend a night school, giving the first money he ever earned, $150, to his blind father to pay his debts. People say he is crazy; his "roaring steam engine will set the house on fire with its sparks"; "smoke will pollute the air"; "carriage makers and coachmen will starve for want of work." For three days the committee of the House of Commons plies questions to him. This was one of them: "If a cow get on the track of the engine traveling ten miles an hour, will it not be an awkward situation?" "Yes, very awkward, indeed, for the coo," replied Stephenson. A government inspector said that if a locomotive ever went ten miles an hour, he would undertake to eat a stewed engine for breakfast.

"What can be more palpably absurd and ridiculous than the prospect held out of locomotives traveling twice as fast as horses?" asked a writer in the English "Quarterly Review" for March, 1825. "We should as soon expect the people of Woolwich to suffer themselves to be fired off upon one of Congreve's rockets as to trust themselves to the mercy of such a machine, going at such a rate. We trust that Parliament will, in all the railways it may grant, limit the speed to eight or nine miles an hour, which we entirely agree with Mr. Sylvester is as great as can be ventured upon." This article referred to Stephenson's proposition to use his newly invented locomotive instead of horses on the Liverpool and Manchester Railroad, then in process of construction.
