"Come with us, Mumps, we want to treat you," answered Tom readily, into whose head another trick had entered.

"I don't want any of your treat," growled the sneak. "Let me go."

"Oh, you must come," urged Tom. "We have a fine bottle of root beer and a lot of candied fruit for you."

If there was one thing that Mumps liked, it was root beer, while he knew candied fruit was very rich eating. Accordingly he hesitated.

"I'll get all I can first and tell on them afterward," he thought, and allowed Tom, and Sam to conduct him into the dormitory occupied by the Metropolitan Sextet.

"Here is Mumps come to join us!" cried Tom, as he introduced the sneak into the room and he winked at Dick. "Now, Mumps, sit down and make yourself at home, and I'll get something for you," and he motioned the sneak to a position at the head of his bed.

He hurried off, and presently came back to Mumps with a fine slice of candied orange. The sneak was greedy, and instantly transferred the entire slice to his mouth and began to chew it vigorously.

"Oh!" he cried presently, and drew down his face in disgust.

"What's the matter, Mumps?" asked Sam.

"This orange tastes like kerosene!" spluttered Mumps, and rushed to the window. As he put out his head, Tom pointed to the sneak and then to the lamp at which he had "flavored" the candied fruit. "We'll get square just wait," he whispered. "You gave me that piece on purpose," howled the sneak, as soon as he had cleared his mouth. "Oh, what an awful dose! Somebody give me a drink of water."
