"He has you there, Professor," chuckled Tad.

"He surely has," agreed the other boys smiling broadly.

"Young men, I admit it. I am properly rebuked, and I assure you the offense will not be repeated. I promise to refrain from anything of the sort in the future, and I shall expect you to do the same."

"Well, I won't promise, but I'll try," drawled Stacy. "If I promised, honest Injun, I'd have to keep my promise. You know I don't like to be roped with a promise. It's like being tied to a tree. A fellow can't let himself out when he wants to."

"You'll have plenty of opportunity to let yourself out, I am thinking. Something do—" began Tad.

"Ah—ah!" warned Chunky.

"I guess I nearly forgot myself, didn't I?" grinned Butler.

"Yes, you'll have to cut it—"

"Whoa, Chunky!" shouted Ned. "There you go again."

"Hopeless! Hopeless!" groaned Professor Zepplin. "But that's right. Correct one another and you will soon overcome the habit. We are forced to live a semi-barbarous life, but that is no reason why we should forget either our manners or our English."
