Apparently Clarence did not like the way that last sentence looked, for he had started to change it several times. Then, thinking he had better write the whole message over again, he had doubtless thrust the first draft into his pocket, and entirely forgotten it.

Jack read it over twice, and looked grave.

“Now what that snake’s up to, I’d give something to know,” he said to himself, as he started to walk on, after placing the message away in his pocket. “Some sort of dirty scheme has been mentioned in a letter, and he’s meaning to pay this Fullerton for doing the thing. What could it be? He says it’s to be done before he and Joe get there. A hundred dollars is a lot of money. Oh! I wonder could he mean to have this other scamp injure our boats in some way?”

It was a dreadful suspicion that beset him right then. How easy for any one to put a lighted match to the canvas tarpaulins that covered the three boats on the steamer’s dock at Clayton. Why, they might be either entirely ruined, or else so badly injured as to be useless for the whole season.

Would Clarence be equal to conspiring to do such a serious thing as this? Jack was sorry to admit that he believed the other was not past it in the least. He had known him to play pranks that savored of the criminal before now; and it had always been his rich father’s money and influence that had saved Clarence from getting the punishment he so richly deserved.

Obeying a sudden inspiration Jack turned and chased back to the railroad station where the telegraph office was located. He knew that the strict orders of the operating company would prevent his seeing the message that Clarence had finally given in, unless they were compelled to show it by a decree of the court. But Jack had no desire to go that deeply just then.

He knew the operator quite well, a young fellow who also sold tickets.

“Clarence Macklin was in here sending a message to Clayton, New York, wasn’t he, Bert?” he asked, trying not to appear at all excited.

“Yes, that’s so, Jack,” came the reply from the agent; who was really an admirer of the young high school pitcher.

“How long ago was that—could I find him in town now, do you think?”
