"Then what do you two say to this letter?" continued the master of Colby Hall, and presented the communication to them.
Jack read the letter with Fred looking over his shoulder. Then, of a sudden, Fred gave a cry of amazement.
"I think I know who wrote that letter!" he exclaimed.
"You do!" returned Colonel Colby and Jack, simultaneously.
"I think so; although, of course, I am not sure." Fred looked at his cousin. "It would be just like him to do it."
"Who are you talking about, Fred?"
"I'm talking about Slugger Brown."
"Slugger Brown!"
"Do you mean Slogwell Brown?" queried the master of the school.
"Yes, sir."
