Julian took the seat pointed out to him, and looked around with curiosity. The cabin was a very dingy apartment, and was dimly lighted by a smoky lantern, which hung suspended from a beam overhead. It contained a rusty cooking stove, a rough table, around which were arranged four long benches to serve in lieu of chairs, and two sides were occupied by bunks in which the crew slept.

One of them, a little apart from the others, was provided with curtains, which, being looped back, revealed a very comfortable-looking bed, that was doubtless intended for Mr. Mortimer. The latter gentleman had nothing to say to Mr. Bowles when he came in, but continued his walk in silence.

Jack took a turn about the cabin, and then seating himself in a chair near his prisoner, folded his arms, rested his chin on his breast, and closed his eyes as if preparing to go to sleep.

Being heavily loaded and short-handed besides, considerable time was consumed in working the flatboat out into the river; but at the end of half an hour a gentle, gliding motion, accompanied by the “lapping” sound of the waves against her sides, told Julian that she was fairly under way.

Presently the captain came below, followed by some of his crew. The men looked curiously at the passengers, especially at Julian, who sat in his chair with his hands tied behind his back, and without any ceremony divested themselves of some of their outer clothing and tumbled into bed.

The captain, after pointing out to his passengers the beds he had arranged for them, followed their example, and presently Mr. Mortimer also sought his couch.

Julian, almost worn down by fatigue and excitement, waited impatiently for Jack to give the signal for retiring, but the latter had no intention of doing anything of the kind. He waited until the sounds which issued from the bunks told him that their occupants were all asleep, and then he beckoned Julian to follow him to the deck. A terrible fear seized upon the boy as he arose to obey. Was Jack about to throw him overboard?

He tottered up the stairs, and when he reached the deck, was astonished beyond measure and immensely relieved by an unexpected proceeding on the part of his keeper, who, instead of conducting him to the side and pitching him into the water, began untying his hands.

“What in the world does he mean, I wonder?” thought Julian. “Does he expect me to remain on board this boat if he gives me the least chance to leave it? If he takes his eyes off me for one instant I’ll astonish him.”

“What are you untying that crazy fellow for?” exclaimed the pilot, who stood with his hand resting on one of the sweeps which served as the rudders of the flatboat. “The cap’n says he’s dangerous.”
