“Say, this is tough luck—to have to write out all that Latin, for something we didn’t do,” complained Frank Nelson.

“I should say so,” added Harry Morse. “Why don’t you own up to it, Fairfield, and save our hides.”

“I guess that’s right,” agreed Harry. “Excuse me, Tom,” and, to the credit of Tom’s classmates, one and all expressed their belief in his innocence. That is, all but Sam, and he kept quiet, avoiding our hero. But, to ward off suspicion, Sam growled louder than anyone about the task.

“I’d like to get hold of the fellow who used that powder,” complained Ed. Ward.

“You won’t have to look far for him, I guess,” said Jack, in a voice that only Tom heard.

“Do you think Sam did it?” asked Tom.
