Regardless of the bullets that struck close, one every now and then coming through the window, Frank poked out his head and fired rapidly several times. Came howls of anguish and directly three men ran for the outer gate.

"Let 'em go," said Frank quietly. "Guess they won't bother us again for some time."

Jack slammed the window shut and dropped a heavy board down behind it. This was protection in case the pirates without tried their luck at shooting through the window.

"Give us some light, Captain Glenn," ordered Frank.

A moment later the interior of the fort was lighted up by the flare of half a dozen candles, Frank turned and surveyed the prisoner. .

"And how are you tonight, Captain Jack?" he asked.

The reply of the pirate chief was irrelevant.

"You've got me," he said, "what do you think you are going to do with me?"

"We haven't figured that out yet," said Frank. "The first thing was to get you. We do one thing at a time, you see."

"Well, you've trouble on your hands now," said Captain Jack. "My men won't rest until they have released me."
