"The fort. Yes. That's what puzzled me," Parmalee said. "I wasn't sure which party was defending it. The sailors mutinied, didn't they? You're fighting them?"

"I should say we are, the——"

He got no further. In their eagerness, the two men had been talking in ordinary tones and had paid no attention to their surroundings. A voice suddenly crackled through the other sounds of the night.

"Well, we've got two of 'em. Hands up, or we'll blow your heads off!"

It was Ditty with half a dozen of the mutineers at his back. They held Drew and Parmalee under the muzzles of their automatics.

It was useless to attempt to escape. Even Drew, reckless as he had shown himself at times, would not take his life so lightly in his hands. And, besides, he knew well that Ditty would be only too glad to shoot him.

His hands, as well as Parmalee's, went up promptly. One of the seamen, laughing a little, came forward and searched them both, taking away Drew's weapon. Parmalee had dropped his useless club.

The young men, so suddenly made captives by the mutineers, stood with their backs to the strong moonlight, their faces in the shadow. The moon was now sinking behind a buttress of the volcano. As yet, neither had been recognized by their captors. But now Ditty came forward, and first of all thrust his face into that of Parmalee.

"Who the devil are you?" he demanded.

The young man lifted his head and stared into the mate's pale eye. Ditty started back with a shriek.
