“Yes, but,” said Irv, “have we any right to tie him? He hasn’t committed any crime.”

“Yes, he has,” said Phil. “At least, we caught him in the act of committing one. He was trying to steal one of Perry Raymond’s skiffs. That’s worth twenty-five dollars. If he hadn’t anything worse in his mind, his attempt on the skiff was grand larceny.”

“That’s so,” said Ed, “and we can turn him over to a magistrate at the first landing for that.”

“I don’t think I shall make any landing,” said Phil, “until we get to Memphis, and in the meantime I am going to know all there is to know about this fellow. When he came on board he had his hair shaved close with a barber’s mowing-machine, but, unfortunately for him, he didn’t bring one of the machines with him. His hair is growing out again now, and I have been comparing several of its little peculiarities closely with descriptions and portraits in the newspapers I got at Cairo of the fellow who is running away with that swag. Boys, I believe we have got the man.”

Phil’s comrades were positively dumb with astonishment. At last the silence was broken.

“If we have,” said Irv Strong, “this voyage will pay, for the rewards offered for this man are very heavy.”

“Yes,” said Phil; “I hadn’t thought of that, but that’s so. There are five thousand dollars on his capture.”

Just then there was a flash in the dark from the cabin scuttle, and a bullet whistled over the heads of the boys. Jim Hughes had managed to extricate himself, in part at least, from his bonds, and had begun to use a weapon which he had doubtless hidden before that time, and of which the boys had known nothing.

Ed was the first to act. He was always exceedingly quick to think. He called to the boys to follow him, and, disregarding Jim’s fusillade, ran to the scuttle.

In an instant, by their united efforts, they pushed the fellow back and closed the lid that covered the stairs. Then Ed remembered that there was a door leading out of the cabin into the hold of the boat. He suggested to two of the boys that they go below, and close that with bales of hay and the like. They did so hurriedly, piling the hay and some apple barrels against the door, until it would have required the strength of half a dozen men to push it open. In the meantime Ed had possessed himself of a hatchet and nails, and had securely nailed down the scuttle.
