Mary's parents showed Jemmy much gratitude for his courageous conduct in saving her life, and the girl clung to him with intense affection; whilst Jemmy, who seemed to think he had acquired some right over her by his having saved her life, was never happy unless he was by her side. They were always together. She would steal in to do her needlework in the place where he was engaged in his trade, and when work was over they were together walking in the lanes and fields.

But in the midst of this happiness a stroke fell on them which for ever altered the tenor of Jemmy's life. Mary fell ill with small-pox. The lad watched by her bedside night and day, giving her medicine, making up her pillow, tending her with agonised heart, utterly forgetful of himself, fearing no risk of infection, heedless of taking his natural rest. The whole time of her illness he never slept, and could scarcely be induced to leave her side for his meals.

On the fifth day she died. The blow was more than Jemmy could bear, and he was prostrated with brain-fever.

That the poor boy had naturally very deep feelings is evident from his having, some few years before, been laid up with fever when his mother died. Hearing of her death whilst he was at school, he became ill and was removed home, where it was some time before he got over the shock. Mary had taken the place in his vacant heart formerly occupied by his mother, and with years the strength of his feelings had increased. Consequently the loss of Mary affected him even more than that of his mother.

In his brain fever he raved incessantly of the poor dead girl, and for several weeks his life was despaired of. By degrees he slowly recovered; but for some time it was feared that his reason was gone. At the end of six or seven months he was able to take a little exercise without attendance; but, as will be seen, he never wholly recovered the blow, and his conduct thenceforth was so eccentric that there can be no doubt his brain was affected.

He left the tanner's, abandoned the trade, and returned to his father's house, where he idled, preying on his fancies—one day in mad, exuberant spirits, the next overwhelmed with despondency.

When aged five-and-twenty he took a fancy to a fine bull-calf belonging to his father, which he called "Jupiter," and he began to train it to perform various tricks, and to break it to bear the saddle. Jupiter bore the bridle patiently enough, but plunged and tossed his horns when the saddle was placed on his back. Jemmy next ventured to mount his back. The young bull stood for a minute or two, as his father said, "right down stagnated," and then began to plunge and kick. Jemmy held fast, and Jupiter, finding he could not thus dislodge his rider, set off, tearing across the paddock towards a thick quickset hedge at the bottom. But instead of leaping it, as Jemmy expected, the bull ran against the fence, and precipitated his rider over the hedge into the ditch on the further side. Jemmy was unhurt, except for a few scratches and some rents in his garments, and patches of mud, and picking himself up, raced after Jupiter, nothing daunted, caught him, and remounting him, mastered the beast. After this he rode Jupiter daily, to the great amusement of people generally, especially when he trotted into Snaith on market-days on the back of the now docile bull.

On the death of his father he was left about £1000. The farm he gave up, having no taste for agriculture, and he took a house on the bank of the river, not far from his old master's the tanner. The house had a few acres of land attached to it, which he cultivated. The old housekeeper, who had known him since a child, followed him to his new home; and in his stable was a stall for Jupiter.

He began to speculate in corn, flax, and potatoes, and having considerable natural shrewdness underlying his eccentric manners, he managed to realise enough to support himself comfortably. He invested £4000 in consols, and had £2000 lying at interest in a neighbouring bank. He rode out with Lord Beaumont's foxhounds, always on Jupiter, who was trained to jump as well as to run. When he was seen coming up on the bull, Lord Beaumont would turn to those with him at the meet and say, "Well, gentlemen, if we are not destined to find game to-day, we may be sure of sport."

His dress was as extraordinary as his mount, for he wore a broad-brimmed hat of lambskin, fully nine feet in circumference; his waistcoat was like Joseph's coat of many colours, made of patchwork; his breeches were of listings of various colours, plaited together by his housekeeper; and he wore yellow boots.
