"I'm going to try to get near enough to see if the mysterious man is aboard, and if he is, I'm going to fire some questions at him, and let him know that he's liable to arrest for entering our house the other night."

"I'd like to fire something else besides questions at him. I've got my small rifle aboard."

"None of that!" objected Frank quickly. "We'll proceed on lawful lines, no matter what he does. Now, Miss Gull," and he patted the rail of the craft, "do your prettiest. See if you can't catch up to those fellows."

The wind continued good and the boys' craft slipped through the water at a lively rate of speed. Andy busied himself in the galley, whence soon came the appetizing odor of coffee, bacon and eggs.

"Hurry up with that!" called Frank. "I'm as hungry as a crab."

"It's almost ready," replied his brother. "Shall I bring it up, or will you come down?"

"You get yours first, and then relieve me. I don't want to eat with one hand and steer with the other. Only don't be all morning, and leave some for me."

There was enough, as Frank soon discovered, and when he came up on deck again he found Andy leaning against the tiller and peering at the distant vessel through the binoculars.

"Can you make out anything?" he asked.

"No, I can see several men aboard, but I don't notice our mysterious friend."
