But at school Jemmy's genius took an altogether perverse turn. He was always first in the playground and last in class; a leader in mischief, a laggard in study. Finding his master's spectacles on the desk one day, Jemmy unscrewed them, and removed the glasses. When the Principal came in, he gravely took up the spectacles and put them on. Finding them dim, he removed them. When he was seen demurely to wipe where the glasses had been, and then, with his fingers through the rims, to hold them up to his eyes to see what was the matter, the whole school burst out laughing. The pedagogue demanded the name of the culprit. Jemmy had not the honesty or courage to proclaim himself the author of the trick, and the whole school was whipped accordingly. On the morning of the 1st April, early, a big boy in his dormitory sent Jemmy to the master, expecting that he would knock at his bedroom door, wake him, and get a thrashing for his pains. Jemmy turned out of bed and went outside the door, waited a minute, and then came into the dormitory again. "Ah! Tom, thou'rt in for it. Thou mun go at once to Lovell for having made an April fool of him and me." The boy, believing this, went to the master's door, knocked him up, and got well thrashed for his pains. "You will know in future what is meant by the biter being bit," said Jemmy, when the boy returned, crying. "There's an old fable about the viper biting the file and breaking his teeth. Perhaps you can understand the moral of it now." The Principal kept an old sow. Jemmy used to get on her back, tie a piece of twine--"band" a Yorkshire boy would call it--to the ring in her snout, run a nail through the heel of his boot to act as spur, and gallop the old sow round the yard. This was often performed with impunity, but not always. The master saw him from his window one morning as he was shaving, and rushed down with a horse-whip in his hand. Jemmy was careering joyously round and round the yard when a crack of the lash across his back dislodged him. He was fed next day on bread and water as a punishment. One night Jemmy and some of his schoolmates got out of the house with intent to rob an orchard. But one of the day scholars had overheard the boarders planning the raid, and he informed the farmer whose orchard it was purposed to rob, and he was on the look-out for the young rogues. When they arrived he suffered one of them--it was Jemmy--to climb an apple-tree without molestation, but then he rushed forth from his hiding-place and laid about him with a carter's whip with hearty good-will. The boys fled in all directions, except Jemmy, who escaped further up the tree, and there remained, unable, like a squirrel, to leap from bough to bough, and so escape. The farmer went under the tree and shouted to him, "Come down, you young rascal! I'll strap thee!"
