"That's it, what are we going to do with him?" his uncle repeated.

"If we could only prove something against him," Bob mused.

"Perhaps we can later," Jack told him.

"But later may be too late."

"Well, there's no use hanging crepe all over the boat about it," Jack grinned. "I'm going to keep a close watch on him and, mark my word, I'll get him where the hair's short if he gives me half a chance."

"Sometimes chances have to be made," Mr. Lakewood said drily.

"And maybe I can do that too," Jack responded.

"Well, about the only thing I can do now is to tell Cap'n Ole about it and put him on his guard, although I think he's watching him pretty closely already," their uncle said, as he pushed back his chair and, followed by the boys, went out on deck.

"We're going to run nor'east for about fifty miles and then tack back nor'west and keep a-zig-zagging back and forth that way so as to cover a pretty big area," he explained as they paused for a moment at the foot of the stairway leading to the bridge.

"Seems to me that ought to hit it," Bob told him.
