it's lucky you found this. I'll turn detective for awhile now. I
wonder how this got into Grimm's room."

"Rolled under door, I guess," replied Budge, speaking more rationally
as he threw away his cud of gum. "From hall, maybe."

"That's it!" exclaimed Jack. "I see it now. Thanks Budge. I hope I
succeed. I'm much obliged to you."

"'Sallright!" exclaimed Budge, as he hurried away to attend to some
of his duties.

When Jack got back to his room he found quite a gathering of his
chums there.

"In for it on account of that Klu-Klux business?" asked Sam Chalmers.

"Not exactly that," answered Jack, "though if I'd stayed at home It
wouldn't have happened."

"Ha-ha-ha-has it g-g-gg-got anything t-t-t--" began Will Slade.

"Whistle it!" exclaimed Bony Balmore.

"Sing it!" came from Fred Kaler. "Here I'll help you out," and he
began to play on his harmonica.

"Whole-wheat-whangdoodles!" cried Nat Anderson, "but tell us, Jack.
Don't keep us in suspense."
