"He's sly enough," he reasoned. "And yet his eyes had a look in them that I never saw before. He looked like a worried wild animal, that doesn't know how to turn or what to do. He's down here all alone among strangers, and evidently he has found out that Sack Todd and the rest aren't his sort. Well, if he wants to reform I shan't put anything in his way. But I am not going to give him too much rope—just yet."

Having gained the deck of the vessel, Dick looked around cautiously. It was a dark night, the stars being hidden by clouds. He crept along slowly.

"Well, you'll have to give me a pointer or two about the engine,"
Dick heard Sack Todd exclaim. "I thought I knew how to run it, but
I reckon I was mistaken."

"Oh, why not let that go just now," growled the mate of the Dogstar in return. "We've got to make sure of those boys first, and get some sleep, too."

"It won't take but a few minutes to explain about the engine," said
Gasper Pold. "I ran one once for six weeks."

"Seems to me you have dabbled in a little bit of everything," observed
Sack Todd.

"So I have."

The three men were near the pilot house, but came away and started for the hatchway leading down into the engine room. They had to pass close to where Dick was crouching and the eldest Rover hardly dared to breathe, so fearful was he of discovery.

Presently Dick saw the three men go down the iron ladder, one after another. As they did this, a sudden idea came into his head.

"I'll do it!" he told himself, and sneaked forward with the silence and quickness of a cat.
