"Let's hear it," was the rejoinder.

"We'll throw our rifles into the open and toss out our revolvers. Then you do the same. We'll all step out then."

"Very good," said the hidden man. "Throw yours out first."

Jack hurled his rifle from him and tossed one revolver into the open. Captain Glenn tossed away his revolvers and rifle, and Williams, acquainted with the plan by a shout, followed suit. The unseen men did likewise. Captain Glenn and Williams stepped out. Their adversaries also left their hiding places. Then Jack saw that one of them covered Captain Glenn and Williams with a revolver. Jack smiled, and taking deliberate aim fired. The man's weapon dropped from his hand.

CHAPTER XVIII

CAPTIVES

When "Captain Jack" admitted to Frank that he was a full-fledged pirate, the lad's first thought was to draw his revolvers and open fire. That was why he dropped his hands to his guns following his exclamation of "Pirates."

Timothy and Allen, the two sailors, taking their cue from Frank, also reached for their weapons. Captain Jack, though realizing on the instant what these movements signified, simply smiled.

"I wouldn't, if I were you," he said quietly.

Frank thought better of his plan to fight and dropped his hands to his side again. He, too, smiled.
