"You bet!" agreed Lance.

So the boys rather hurried the departure of the crowd for the place where the boats had been left, and where they had lunched. The walk through the cove did not take long, and the party, happy and laughing, crowded out upon the shore of the cove in front of the subterranean passage.

Instantly one of the twins drew the attention of all by uttering a startled little scream.

"What's the matter with you—er—Sister?" demanded the other Lockwood girl, with a chuckle.

"That wasn't the man we saw with Tony!" declared the girl who had cried out.

"What man?"

"The pirate," said the twin.

"How do you know?" demanded Laura, laughing.

"For I just saw him again. And he couldn't have gotten through the cave ahead of us."

"There are prowlers about," declared Chet to Lance.
