"I'm not small enough," said Jimmieboy; "but I'll eat that apple you spoke about, and maybe it'll make me shrink, though I don't see how it can." "Easy enough. Haven't you seen a boy doubled up after eating an apple? Of course you have; perhaps you were the boy. At any rate there is no reason why, if an apple can work that way, it can't work the other. It's a poor rule that won't work both ways, and an apple is pretty good, as a rule, and so you have it proved without trying that what I say is true. Here's the apple; eat it as quickly as you can and give me the core." Jimmieboy took the dainty piece of fruit in his hand and ate it with much relish, for it was a very sweet apple, and he was fond of that sort of thing. Unfortunately, he liked it so well that he forgot to give the core to the Imp, and, when in a moment he felt himself shrinking up, and the Imp asked for the core, he was forced blushingly to confess that he had been very piggish about it, and had swallowed the whole thing. "I've half a mind not to let you in at all!" cried the Imp, stamping his foot angrily upon the floor, so angrily that the bells rang out softly as if in remonstrance. "In fact, I don't see how I can let you in, because you have disobeyed me about that core." "I'm surprised at you," returned Jimmieboy, slightly injured in feeling by the Imp's behavior. "I wouldn't make such a fuss about an old apple-core. If you feel as badly about it as all that, I'll run down into the kitchen and get you a whole apple--one as big as you are." "That isn't the point at all," said the Imp. "I didn't want the core for myself at all. I wanted it for you." "Well, I've got it," said Jimmieboy, who had now shrunk until he was no taller than the Imp himself, not more than two inches high. "Of course you have, and if you will notice it is making you grow right back again to the size you were before. That's where the trouble comes in with those trick apples. The outside makes you shrink, and the core makes you grow. When I said I wanted the core I meant that I wanted it to keep until we had had our trip together, so that when we got back you could eat it, and return to your papa and mamma just as you were in the beginning. Just run to the parlor mirror now and watch yourself." Jimmieboy hastened into the parlor, and climbing upon the mantel-piece gazed into the mirror, and, much to his surprise, noticed that he was growing fast. He was four inches high when he got there, and then as the minutes passed he lengthened inch by inch, until finally he found himself just as he had been before he ate the apple. "Well, what are you going to do about it?" he asked, when he returned to the telephone. "I don't know," said the Imp. "It's really too bad, for that's the last apple of that sort I had. The trick-apple trees only bear one apple a year, and I have been saving that one for you ever since last summer, and here, just because you were greedy, it has all gone for nothing."
