"I know that, Mr. Strong," answered Tom. "But Flapp struck me first."

"It isn't so!" cried the big boy. "I wasn't doing anything, when Rover came along and started to quarrel."

"My brother Sam and Harry Moss can prove that Flapp struck me first."

"That is true," said Harry Moss, while Sam nodded.

"What was the quarrel about?"

"I caught him here, beating Harry with this boat chain. I told him to stop and then he pitched into me."

"Is this true, Moss?"

"Ye—yes, sir, but—I—I—didn't want to say anything about it, sir."

"Do you mean to say that Flapp attacked you with that chain?"
