On the morning of the 8th of October the "Rocket" was again ready for the contest. The engine was taken to the extremity of the stage, the fire-box was filled with coke, the fire lighted, and the steam raised until it lifted the safety-valve loaded to a pressure of fifty pounds to the square inch. This proceeding occupied fifty-seven minutes. The engine then started on its journey, dragging after it about thirteen tons weight in wagons, and made the first ten trips backward and forward along the two miles of road, running the thirty-five miles, including stoppages, in an hour and forty-eight minutes. The second ten trips were in like manner performed in two hours and three minutes. The maximum velocity attained during the trial trip was twenty-nine miles an hour, or about three times the speed that one of the judges of the competition had declared to be the limit of possibility. The average speed at which the whole of the journeys were performed was fifteen miles an hour, or five miles beyond the rate specified in the conditions published by the company. The entire performance excited the greatest astonishment among the assembled spectators; the directors felt confident that their enterprise was now on the eve of success; and George Stephenson rejoiced to think that, in spite of all false prophets and fickle counsellors, the locomotive system was now safe. When the "Rocket," having performed all the conditions of the contest, arrived at the "grand stand" at the close of its day's successful run, Mr. Cropper--one of the directors favorable to the fixed-engine system--lifted up his hands, and exclaimed, "Now has George Stephenson at last delivered himself."

Neither the "Novelty" nor the "Sanspareil" was ready for trial until the 10th, on the morning of which day an advertisement appeared, stating that the former engine was to be tried on that day, when it would perform more work than any engine on the ground. The weight of the carriages attached to it was only seven tons. The engine passed the first post in good style; but in returning, the pipe from the forcing-pump burst and put an end to the trial. The pipe was afterward repaired, and the engine made several trips by itself, in which it was said to have gone at the rate of from twenty-four to twenty-eight miles an hour.

The "Sanspareil" was not ready until the 13th; and when its boiler and tender were filled with water, it was found to weigh four hundred-weight beyond the weight specified in the published conditions as the limit of four-wheeled engines; nevertheless, the judges allowed it to run on the same footing as the other engines, to enable them to ascertain whether its merits entitled it to favorable consideration. It travelled at the average speed of about fourteen miles an hour with its load attached; but at the eighth trip the cold-water pump got wrong, and the engine could proceed no farther.

It was determined to award the premium to the successful engine on the following day, the 14th, on which occasion there was an unusual assemblage of spectators. The owners of the "Novelty" pleaded for another trial, and it was conceded. But again it broke down. Then Mr. Hackworth requested the opportunity for making another trial of his "Sanspareil." But the judges had now had enough of failures, and they declined, on the ground that not only was the engine above the stipulated weight, but that it was constructed on a plan which they could not recommend for adoption by the directors of the company. One of the principal practical objections to this locomotive was the enormous quantity of coke consumed or wasted by it,--about six hundred and ninety-two pounds per hour when travelling,--caused by the sharpness of the steam-blast in the chimney, which blew a large proportion of the burning coke into the air.

The "Perseverance" of Mr. Burstall was found unable to move at more than five or six miles an hour, and it was withdrawn from the contest at an early period. The "Rocket" was thus the only engine that had performed, and more than performed, all the stipulated conditions; and it was declared to be entitled to the prize of £500, which was awarded to the Messrs. Stephenson and Booth[20] accordingly. And farther to show that the engine had been working quite within its powers, George Stephenson ordered it to be brought upon the ground and detached from all incumbrances, when, in making two trips, it was found to travel at the astonishing rate of thirty-five miles an hour.

The "Rocket" had thus eclipsed the performances of all locomotive engines that had yet been constructed, and outstripped even the sanguine expectations of its constructors. It satisfactorily answered the report of Messrs. Walker and Rastrick, and established the efficiency of the locomotive for working the Liverpool and Manchester Railway, and indeed all future railways. The "Rocket" showed that a new power had been born into the world, full of activity and strength, with boundless capability of work. It was the simple but admirable contrivance of the steam-blast, and its combination with the multitubular boiler, that at once gave locomotion a vigorous life, and secured the triumph of the railway system. As has been well observed, this wonderful ability to increase and multiply its powers of performance with the emergency that demands them, has made this giant engine the noblest creation of human wit, the very lion among machines.

The success of the Rainhill experiment, as judged by the public, may be inferred from the fact that the shares of the company immediately rose ten per cent, and nothing farther was heard of the proposed twenty-one fixed engines, engine-houses, ropes, etc. All this cumbersome apparatus was thenceforth effectually disposed of.

When the reading was over, Bedford said: "When I heard you were going to have George Stephenson this afternoon, I wrote to my cousin Prentiss Armstrong, who has been at the locomotive works at Altoona for several years, and asked him about locomotives nowadays, that I might be able to compare them with the locomotives of George Stephenson's time. This is his letter, which I'll read, if there be no objection:"--

DEAR BEDFORD,--Speaking roughly, a freight-engine of the "Consolidation" type (eight driving-wheels and two truck-wheels) weighs from forty-seven to forty-eight tons of two thousand pounds. On a road with no grades over twenty feet to the mile (1 in 250) it will haul over one thousand tons at fifteen miles an hour. If the train is of merchandise, it will be of say fifty cars, each weighing ten tons and carrying ten tons. If it is of coal or ore, the cars will each carry twenty or twenty-five tons.

["The 'Rocket,'" said Bedford, "which was the successful engine at the Rainhill competition, weighed a little over four tons and had four wheels. Dragging a weight of thirteen tons in wagons, it made thirty-five miles in about two hours."]

Our Engine No. 2 [continued the letter] made a mile on a level in forty-three seconds with no train, but there are very few such records. Two of our fast trains (four cars each, weighing twenty-five tons) make a schedule in one place (level) of nine miles in eight minutes. I have seen a record of a run on the Bound Brook route of four cars, ten miles in eight minutes. I think this must have been down hill.

I hope these facts will answer your views. If there's anything else that I can get up for you, I shall be glad to do it.

Yours truly, PRENTISS ARMSTRONG.

ELI WHITNEY.

The young people all came in laughing.

"And what is it?" said Uncle Fritz, good-naturedly.

"It is this," said Alice, "that I say that all this is very entertaining about Palissy the Potter and Benvenuto Cellini; and I have been boasting that I know as much of the steam-engine as Lucy did, who was 'sister to Harry.' But I do not see that this is going to profit Blanche when she shall make her celebrated visit to Mr. Bright, and when he asks her what is the last sweet thing in creels or in fly-frames."

"Is it certain that Blanche is to go?" said Uncle Fritz, doubtfully.

"Oh, dear, Uncle Fritz, do you know?" said Blanche, in mock heroics; "are you in the sacred circle which decides? Will the Vesuvius pass its dividend, or will it scatter its blessings right and left, so that we can go to Paris and all the world be happy?"

"I wish I knew," said Colonel Ingham; "for on that same dividend depends the question whether I build four new rooms at Little Crastis for the accommodation of my young friends when they visit me there."

"Could you tell us," said Fergus, "what is the cause of the depression in the cotton-manufacture?"

"Don't tell him, Uncle Fritz," said Fanchon, "for the two best of reasons,--first, that half of us will not understand if you do; and second, that none of us will remember."

Colonel Ingham laughed. "And third," he said, "that we are to talk about Inventions and Inventors, and we shall not get to Fergus's grand question till we come to the series on 'Political Economy and Political Economists.'

"You are all quite right in all your suggestions and criticisms. It is quite time that you girls should know something of the industry which is important not only to all the Southern States, but to all the manufacturing States. Cotton is the cheapest article for clothing in the world, and the use of it goes farther and farther every year. The manufacture is also improving steadily. Thirty men, women, and children will make as much cotton cloth to-day as a hundred could make the year you were born, Hester. I saw cottons for sale to-day at four cents a yard which would have cost nearly three times that money thirty years ago. So I have laid out for you these sketches of the life of Eli Whitney, on whose simple invention, as you remember, all this wealth of production may be said to depend. You college boys ought to be pleased to know, that within a year after this man graduated from Yale College, he had made an invention and set it a going, which entirely changed the face of things in his own country. At that moment there was so little cotton raised in America, that Whitney himself had never seen cotton wool or cotton seed, when he was first asked if he could make a machine which would separate one from the other. It was so little known, indeed, that when John Jay of New York negotiated a treaty of commerce with England in 1794, the year after Whitney's invention, he did not know that any cotton was produced in the United States. The treaty did not provide for our cotton, and had to be changed after it was brought back to America. With this invention by Whitney, it was possible to clean cotton from the seed. The Southern States, which before had no staple of importance, had in that moment an immense addition to their resources. Alabama, Mississippi, Louisiana, and Tennessee, besides the States in the old thirteen, were settled almost wholly to call into being new lands for raising cotton. To these were afterwards added Arkansas, Florida, and Texas. With this new industry slave labor became vastly more profitable; and the institution of slavery, which would else have died out probably, received an immense stimulus. Fortunately for the country and the world, the Constitution had fixed the year 1808, as the end of the African slave trade. But, up to that date, slaves were pushed in with a constantly increasing rapidity, so that the new States were peopled very largely with absolute barbarians. There is hardly another instance in history where it is so easy to trace in a very few years, results so tremendous following from a single invention by a single man.

"Fortunately for us, Miss Lamb has just published a portrait of Eli Whitney in the 'Magazine of History.' Here it is, in the October number of the 'Magazine of History.'

"As to processes of manufacture, of course we can learn little or nothing about them here. But you had better read carefully this article in Ure's 'Dictionary of Arts,' though it is a little old-fashioned, and then you will be prepared to make up parties to go out to the Hecla, or up to Lowell or Lawrence, where you can see with your own eyes.

"And now I will read you a little sketch of the life of Eli Whitney."

ELI WHITNEY.

Eli Whitney was born at Westborough, Worcester County, Massachusetts, Dec. 8, 1765. His parents belonged to the middle class in society, who, by the labors of husbandry, managed by uniform industry and strict frugality to provide well for a rising family.

The paternal ancestors of Mr. Whitney emigrated from England among the early settlers of Massachusetts, and their descendants were among the most respectable farmers of Worcester County. His maternal ancestors, of the name of Fay, were also English emigrants, and ranked among the substantial yeomanry of Massachusetts. A family tradition respecting the occasion of their coming to this country may serve to illustrate the history of the times. The story is, that about two hundred years ago, the father of the family, who resided in England, a man of large property and great respectability, called together his sons and addressed them thus: "America is to be a great country. I am too old to emigrate myself; but if any one of you will go, I will give him a double share of my property." The youngest son instantly declared his willingness to go, and his brothers gave their consent. He soon set off for the New World, and landed in Boston, in the neighborhood of which place he purchased a large tract of land, where he enjoyed the satisfaction of receiving two visits from his venerable father. His son John Fay, from whom the subject of this memoir is immediately descended, removed from Boston to Westborough, where he became the proprietor of a large tract of land, since known by the name of the Fay Farm.

From the sister of Mr. Whitney, we have derived some particulars respecting his childhood and youth, and we shall present the anecdotes to our readers in the artless style in which they are related by our correspondent, believing that they would be more acceptable in this simple dress than if, according to the modest suggestion of the writer, they should be invested with a more labored diction. The following incident, though trivial in itself, will serve to show at how early a period certain qualities of strong feeling tempered by prudence, for which Mr. Whitney afterward became distinguished, began to display themselves. When he was six or seven years old he had overheard the kitchen maid, in a fit of passion, calling his mother, who was in a delicate state of health, hard names, at which he expressed great displeasure to his sister. "She thought," said he, "that I was not big enough to hear her talk so about my mother. I think she ought to have a flogging; and if I knew how to bring it about, she should have one." His sister advised him to tell their father. "No," he replied, "it will hurt his feelings and mother's too; and besides, it is likely the girl will say she never said so, and that would make a quarrel. It is best to say nothing about it."

Indications of his mechanical genius were likewise developed at a very early age. Of his early passion for such employments, his sister gives the following account: "Our father had a workshop, and sometimes made wheels of different kinds, and chairs. He had a variety of tools, and a lathe for turning chair-posts. This gave my brother an opportunity of learning the use of tools when very young. He lost no time; but as soon as he could handle tools, 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 had been making a fiddle. 'Ah,' said he, despondingly, 'I fear Eli will have to take his portion in fiddles.' He was at this time about twelve years old. His sister adds that this fiddle was finished throughout, like a common violin, and made tolerably good music. It was examined by many persons, and all pronounced it to be a remarkable piece of work for such a boy to perform. From this time he was employed to repair violins, and had many nice jobs, which were always executed to the entire satisfaction, and often to the astonishment, of his customers. His father's watch being the greatest piece of mechanism that had yet presented itself to his observation, he was extremely desirous of examining its interior construction, but was not permitted to do so. One Sunday morning, observing that his father was going to meeting, and would leave at home the wonderful little machine, he immediately feigned illness 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 its motions that he took it all to pieces before he thought of the consequences of his rash deed; for his father was a stern parent, and punishment would have been the reward of his idle curiosity, had the mischief been detected. He, however, put all the work so neatly together that his father never discovered his audacity until he himself told him, many years afterwards.

"Whitney lost his mother at an early age, and when he was thirteen years old his father married a second time. His stepmother, among her articles of furniture, had a handsome set of table knives that she valued very highly. Whitney could not but see this, and said to her, 'I could make as good ones if I had tools, and I could make the necessary tools if I had a few common tools to make them with.' His stepmother thought he was deriding her, and was much displeased; but it so happened, not long afterwards, that one of the knives got broken, and he made one exactly like it in every respect except the stamp on the blade. This he would likewise have executed, had not the tools required been too expensive for his slender resources."

When Whitney was fifteen or sixteen years of age he suggested to his father an enterprise, which was an earnest of the similar undertakings in which he engaged on a far greater scale in later life. This being the time of the Revolutionary War, nails were in great demand and bore a high price. At that period nails were made chiefly by hand, with little aid from machinery. Young Whitney proposed to his father to procure him a few tools, and to permit him to set up the manufacture. His father consented; and he went steadily to work, and suffered nothing to divert him from his task until his day's work was completed. By extraordinary diligence he gained time to make tools for his own use, and to put in knife-blades, and to perform many other curious little jobs which exceeded the skill of the country artisans. At this laborious occupation the enterprising boy wrought alone, with great success, and with much profit to his father, for two winters, pursuing the ordinary labors of the farm during the summers. At this time he devised a plan for enlarging his business and increasing his profits. He whispered his scheme to his sister, with strong injunctions of secrecy; and requesting leave of his father to go to a neighboring town, without specifying his object, he set out on horseback in quest of a fellow-laborer. Not finding one as easily as he had anticipated, he proceeded from town to town with a perseverance which was always a strong trait of his character, until, at a distance of forty miles from home, he found such a workman as he desired. He also made his journey subservient to his mechanical skill, for he called at every workshop on his way and gleaned all the information he could respecting the mechanical arts.

At the close of the war the business of making nails was no longer profitable; but a fashion prevailing among the ladies of fastening on their bonnets with long pins, he contrived to make those with such skill and dexterity that he nearly monopolized the business, although he devoted to it only such seasons of leisure as he could redeem from the occupations of the farm, to which he now principally betook himself. He added to this article, the manufacture of walking-canes, which he made with peculiar neatness.

In respect to his proficiency in learning while young, we are informed that he early manifested a fondness for figures and an uncommon aptitude for arithmetical calculations, though in the other rudiments of education he was not particularly distinguished. Yet at the age of fourteen he had acquired so much general information, as to be regarded on this account, as well as on account of his mechanical skill, a very remarkable boy.

From the age of nineteen, young Whitney conceived the idea of obtaining a liberal education; but, being warmly opposed by his stepmother, he was unable to procure the decided consent of his father, until he had reached the age of twenty-three years. But, partly by the avails of his manual labor and partly by teaching a village school, he had been so far able to surmount the obstacles thrown in his way, that he had prepared himself for the Freshman Class in Yale College, which he entered in May, 1789.

The propensity of Mr. Whitney to mechanical inventions and occupations, was frequently apparent during his residence at college. On a particular occasion, one of the tutors, happening to mention some interesting philosophical experiment, regretted that he could not exhibit it to his pupils, because the apparatus was out of order and must be sent abroad to be repaired. Mr. Whitney proposed to undertake this task, and performed it greatly to the satisfaction of the faculty of the college.

A carpenter being at work upon one of the buildings of the gentleman with whom Mr. Whitney boarded, the latter begged permission to use his tools, during the intervals of study; but the mechanic, being a man of careful habits, was unwilling to trust them with a student, and it was only after the gentleman of the house had become responsible for all damages, that he would grant the permission. But Mr. Whitney had no sooner commenced his operations than the carpenter was surprised at his dexterity, and exclaimed, "There was one good mechanic spoiled when you went to college."

Soon after Mr. Whitney took his degree, in the autumn of 1792, he entered into an engagement with a Mr. B. of Georgia, to reside in his family as a private teacher. On his way thither, he was so fortunate as to have the company of Mrs. Greene, the widow of General Greene, who, with her family, was returning to Savannah after spending the summer at the North. At that time it was deemed unsafe to travel through our country without having had the small-pox, and accordingly Mr. Whitney prepared himself for the excursion, by procuring inoculation while in New York. As soon as he was sufficiently recovered, the party set sail for Savannah. As his health was not fully re-established, Mrs. Greene kindly invited him to go with the family to her residence at Mulberry Grove, near Savannah, and remain until he was recruited. The invitation was accepted; but lest he should not yet have lost all power of communicating that dreadful disease, Mrs. Greene had white flags (the meaning of which was well understood) hoisted at the landing and at all the avenues leading to the house. As a requital for her hospitality, her guest procured the virus and inoculated all the servants of the household, more than fifty in number, and carried them safely through the disorder.
