"Yes, you can!" broke in Nappy. And thereupon, somewhat against his will, Codfish penned the two notes in as much of a disguised hand as was possible for him.
"But I'm not going to deliver the notes," he warned feebly. "You two have got to do that much."
"All right, we will," answered Slugger. He turned to his crony. "You slip one of them under Professor Lemm's door, and I'll place the other on Colonel Colby's desk."
"All right, but be careful."
"Bet your life!"
Asa Lemm was just finishing his morning toilet and grumbling over the happenings of the night, when he chanced to glance toward the door of his room, and at that moment saw a letter thrust under it. He stared for an instant in amazement, and then rushed forward and threw the door wide open. But his movement, quick as it was, came too late, for Nappy Martell had already slipped around a corner and made his escape. Taking up the letter, the professor read the contents with great interest. The communication ran as follows:
"Dear Professor Lemm:
"If you want to know more about the trouble last night, ask John Rover and Walter Baxter. They had the two billy goats. I think you will find that all of the Rovers and the boys who go with them were in this joke.
"Yours respectfully,
"One Who Knows."
"So that's who is guilty!" muttered the teacher, after reading the letter a second time. "The Rovers, eh? I might have known it because of the trouble I have had with them in the classroom. And I remember now that I have also had trouble with that Baxter boy. I must see Colonel Colby about this at once."
The professor hurried downstairs, and found that Colonel Colby had entered his office but a few minutes before, and was perusing the communication left there secretly by Slugger Brown.
"I have found out who was guilty last night," snapped Asa Lemm, as he flourished the letter in his hand.
