Strange how things will fly through the mind at times, when there is any cause for excitement. Jack thought of a score of facts calculated to back up his theory, even while he was standing there, with the throbbing of the lost boat still sounding faintly in his ears.

Whatever of mystery there might be about the actions of the man who had run off with the Saunterer, this was really no time for explanations, or to try and figure things out. Later on, when it was all over, and they could sit comfortably beside a camp fire, it would be fun to piece things together, and find out just what had influenced all these events to come about.

“Boys,” Jack said, turning to his friends, “I’ve just come to the conclusion that we’ve run across one of those bank thieves after all.”

“You mean the chap who stole my boat?” ejaculated Algernon, “goodness gracious! who would have thought now, that I’d come in contact with such desperate characters in my little run down-river. And he shot my man, too; see, Jenks is getting one of your friends, to wrap a rag around his arm. This is thrilling. It makes my blood run cold to think that I was actually so close to a real burglar. Won’t I have the story to tell Chauncey, though? But how am I ever to get off this island, and try to recover my boat?”

“Leave that to us, Algernon,” said Jack, quietly.

“Hurrah! Jack’s taken the job on!” shouted Josh, excitedly, “and when he says he’ll see it through, you can bet your boots he means business. What are we going to do about it, Jack?”

All eyes were of course turned upon the Commodore. In this critical time they seemed to depend on him to lead the way out of the maze. Jack would know what to do; that was what the rest always said to each other, as soon as any serious difficulty arose.

And Jack simply raised his hand as if to call for silence, as he said:

“Wait a minute, fellows, I want to listen to what those rapid-fire explosions aboard the white motor boat are telling me. They’re getting louder again, you notice, with every minute that passes.”
