Eighteen years old by this time, George Stephenson was wholly uneducated. His father's small earnings, and the large family he had to feed, at a time when provisions were scarce and at war prices, prevented his having any schooling in his early years; and he now set himself to repair his deficiencies in that respect. His duties occupied him twelve hours a-day, so that he had but little leisure to himself; but he was bent on improving himself, and after the duties of the day were over, went to a night-school kept by a poor teacher in the village of Water-row, where he was now situated, on three nights during the week, to take lessons in reading and spelling, and afterwards in the science of pot-hooks and hangers as well; so that by the time he was nineteen he was able to read clearly, and to write his own name. Then he took to arithmetic, for which he showed a strong predilection. He had always a sum or two by him to work out while at the engine side, and soon made great progress.

The next year he was appointed brakesman at Black Collerton Colliery, with six shillings added to his wages, which were now nearly a pound a-week, and he was always making a few shillings extra by mending his fellow-workmen's shoes, a job at which he was rather expert. Busy as he was with his various tasks, he found time to fall in love. Pretty Fanny Henderson, a servant at a neighbouring farm, caught his fancy; and getting her shoes to mend, it cost him a great effort to return them to the comely owner after they were patched up. He carried them about with him in his pocket for some time, and would pull them out, and then gaze fondly at them with as much emotion as the old story tells us the sight of the dainty glass slipper, which Cinderella dropped at the ball, excited in the breast of the young prince. Bent upon taking up house for himself, with Fanny as presiding genius, Stephenson now began to save up, and declared himself a "rich man" when he put his first guinea in the box.

Instead of spending the Saturday afternoon with his fellow-workmen in the public-house, Stephenson employed himself in taking the engine to pieces, and cleaning it; but besides his attention to work, he was also remarkable for his skill at putting and wrestling, in which he beat most of his comrades. And he was not without pluck either, as he let a great hulking fellow, who was the bully of the village, know to his cost, by giving him such a drubbing as made him a "sadder and wiser man" for some time afterwards. He still continued his attendance at the night-school, till he had got out of the master as much instruction in arithmetic as he was able to supply.

By the time he was of age he had saved up enough to take a little cottage and furnish it comfortably, though, of course, very humbly; and in the winter of 1802, Fanny, now Mrs. George Stephenson, rode home from church on horseback, seated on a pillion behind her husband, with her arms round his waist; and very proud and happy, we may be sure, he was that day, as the neighbours came to their doors to wish him "God speed" in his new mode of life.

Having learned all he could from the village teacher, George Stephenson now began to study mensuration and mathematics at home by himself; but he also found time to make a number of experiments in the hope of finding out the secret of perpetual motion, and to make shoe-lasts and shoes, as well as mend them. At the end of 1803 his only son, Robert, was born; and soon after the family removed to Killingworth, seven miles from Newcastle, where George got the place of brakesman. They had not been settled long here when Fanny died—a loss which affected George deeply, and attached him all the more intensely to the offspring of their union. At this time everything seemed to go wrong with him. As if his wife's death was not grief enough, his father met with an accident which deprived him of his eye-sight, and shattered his frame; George himself was drawn for the militia, and had to pay a heavy sum of money for a substitute; and with his father, and mother, and his own boy to support, at a time when taxes were excessive and food dear, he had only a salary of £50 or £60 a-year to meet all claims. He was on the verge of despair, and would have emigrated to America, if, fortunately for our country, he had not been unable to raise sufficient money for his passage. So he had to stay in the old country, where a bright and glorious future awaited him, dark and desperate as the prospect then appeared.

He still went on making models and experiments, and perfecting his knowledge of his own engine. To add to his earnings he also took to clock-cleaning, with the view of saving up enough to give his boy the best education it was in his power to bestow. "In the earlier period of my career," he used afterwards to say, "when Robert was a little boy, I saw how deficient I was in education, and I made up my mind that he should not labour under the same defect, but that I would put him to a good school, and give him a liberal training. I was, however, a poor man, and how do you think I managed? I betook myself to mending my neighbours' clocks and watches at nights, after my daily labour was done, and thus I procured the means of educating my son." George began by teaching his son to work with him; and when the little chap could not reach so high as to put a clock-hand on, would set him on a chair for the purpose, and very proud Robert was whenever he could "help father" in any of his jobs.

About this time a new pit having been sunk in the district where he worked, the engine fixed for the purpose of pumping the water out of the shaft was found a failure. This soon reached George's ears. He walked over to the pit, carefully examined the various parts of the machinery, and turned the matter over in his mind. One day when he was looking at it, and almost convinced that he had discovered the cause of the failure, one of the workmen came up, and asked him if he could tell what was wrong.

"Yes," said George; "and I think I could alter it, and in a week's time send you to the bottom."

George offered his services to the engineer. Every expedient had been tried to repair the engine, and all had failed. There could be no harm, if no good, in Stephenson trying his hand at it. So he got leave, and set to work. He took the engine entirely to pieces, and in four days had repaired it thoroughly, so that the workmen could get to the bottom and proceed with their labours. George Stephenson's skill as an engine-doctor began to be noised abroad, and secured him the post of engine-wright at Killingworth, with a salary of £100 a-year. Robert was now old enough to go to school, and was sent to one in Newcastle, to which, dressed in a suit of coarse grey stuff cut out by his father, he rode every day upon a donkey. Robert spent much of his spare time in the Literary and Philosophical Institute of Newcastle; and would sometimes take home a volume from the library, which father and son would eagerly peruse together. Occasionally they tried chemical experiments together; and now and then Robert would try his hand by himself. On one occasion he electrified the cows in an adjacent enclosure by means of an electric kite, making the bewildered animals dash madly about the field, with their tails erect on end; and another time he administered a severe electric shock to his father's Galloway pony, which nearly knocked it over, and drew down upon him the affected wrath of his father, who, coming out at the instant, shook his whip at him and called him a mischievous scoundrel, though pleased all the while at the lad's ingenuity and enterprise. As an early proof of the former, there still stands over the cottage door at Killingworth a sun-dial, constructed by Robert when he was thirteen years old, with some little help from his father.

The idea of constructing a steam-engine to run on the colliery tram-roads leading to the shipping-place was now receiving considerable attention from the engineering community. Several schemes had been propounded, and engines actually made; but none of them had been brought into use. A mistaken notion prevailed that the plain round wheels of an engine would slip round without catching hold of the rails, and that thus no progress would be made; but George Stephenson soon became convinced that the weight of the engine would of itself be sufficient to press the wheels to the rails, so that they could not fail to bite. He turned the subject over and over in his mind, tested his conceptions by countless experiments, and at length completed his scheme. Money for the construction of a locomotive engine on his plan having been supplied by Lord Ravensworth, one was made after many difficulties, and placed upon the tram-road at Killingworth, where it drew a load of 30 tons up a somewhat steep gradient at the rate of four miles an hour. Still there was very little saving in cost, and little advance in speed as compared with horse-power; but in a second one, which Stephenson quickly set about constructing, he turned the waste steam into the chimney to increase the draught, and thus puff the fuel into a brisker flame, and create a larger volume of steam to propel the locomotive. The fundamental principles of the engine thus formed remain in operation to this day; and it may in truth be termed the progenitor of the great locomotive family.
