"How would it do for some of us to land and keep out of sight and come around back of them?" asked Cas Temple.

"What are we going to do with them if we catch them?" Tom Corwin wanted to know. "Take them back and hand them over to the police?"

"I don't believe they'll let us catch them," answered Phil. "Either they'll take to that small boat they've got astern there or they'll try to make a dash past us."

"It is!" he cried. "We've got her, fellows!"

"Much good that would do them!" Harry shrugged his shoulders. "The Adventurer can sail all around our boat."

"We're not getting anywhere," observed Steve, who had been all the while watching the other craft attentively. "And they've seen us at last, for they're looking over the top of the cabin."

"Well, let's do something," said Perry, who was back with the two revolvers and as many boxes of cartridges. "Can they go the other way or do they have to pass us to get out of this place, Steve?"

"They can go the other way for about five miles according to the chart, but they can't get out. There's a bridge there. And, anyway, I guess it's only navigable for small boats at high tide. Perry, for the love of lemons, drop those things and let them alone."
