The man at the wheel must have stared hard at seeing the two boys thus start forward instead of jumping overboard like those others had done. Perhaps he even gave them credit for the same species of sublime courage that the skipper possessed. When, presently, he saw what they were doing, astonishment kept him from trying to interfere until it was too late to do any good.

Seizing hold of the heavy hatch, the two boys managed to throw it into place. There was means for securing it so that even if great waves swept over the low deck of the powerboat they could hardly tear the hatch loose, and flood the hold.

Thanks to his habit of observation, Jack knew all about this, and also how the fastenings were applied. Amos, taking his cue from his comrade, also gave such assistance as lay in his power; and between them they speedily managed to accomplish their desired end.

Hardly had they succeeded in doing this than there came heavy pounding on the other side of the hatch. Evidently the skipper had learned how he had been made the victim of what he would call a “scurvy trick”; and was fairly wild to force a way out of the hold, so that he could punish those responsible for it.

Jack had not forgotten the man at the wheel, who had it in his power, should the inclination come to him, to injure the engine of the boat in some way, so as to prevent any further progress.

As this would be greatly to the disadvantage of the two comrades, Jack did not mean to permit the man to have the least chance of carrying out his intention.

Leaving Amos standing by the battened hatch, pistol in hand, Jack rushed straight toward the man at the wheel. He covered him with his weapon, and, under the belief that the fellow knew English, for he had conversed with several of the crew before then, the boy called out sternly:

“Stay where you are, and hold the wheel, and no injury will come to you. There is no fire and we will not be blown up. It was a trick to get the captain down in the hold. He is our prisoner, and we expect to run this boat from now on. Do you understand what I am saying?”

The sailor looked a little dazed as though events were happening with such wonderful rapidity that he could hardly keep track of them. Still he seemed to be able to understand English, especially when accompanied by the significant gestures Jack was making with the little automatic pistol.

He immediately elevated his right hand. That was doubtless intended to show his willingness to submit to whatever fate the daring captors of the powerboat felt inclined to impose upon him.
