"Mr. Crabtree, if you want to know about the teeth, let me confess that I took them and hung them up where they were found," said Pepper.

"Ha! so you are willing to confess, eh?"

"I am. I did it for fun—but I suppose you don't see the fun," added Pepper, dryly, so dryly in fact that George Strong had to turn away to hide a sudden smile.

"It was a low, contemptible trick!" returned Josiah Crabtree. "But I must say I do not think it quite as bad as your other doings."

"My other doings?" asked The Imp, somewhat mystified.

"Mr. Crabtree, do not be hasty, I beg of you," put in the under teacher.

"Ditmore, how did you get the teeth?" demanded Josiah Crabtree.

"It was very easy, sir, if you must know. I went into the vacant bedroom next to your room, climbed from one window to the other, and the trick was done."

"Were you alone?"

"Yes, sir, absolutely alone."
