"They could put a couple of bullets where they would play hob with us," went on Dick, "and they must know it."

"They do know it," said Matt. "There are four of the Japs, and only two guns. I rather surmise that they have used up all the ammunition in the magazines of the rifles, and that their reserve supply is on the Pom."

Just at that moment Glennie swerved the Grampus to pass between the stern of the Pom and the shore.

"Ready, Dick!" warned Matt.

"Right-o," answered Dick, seizing one end of the cable and balancing himself on the port side of the Grampus. "Swing her as close as you can, Glennie," he added to the ensign.

Supporting himself by clinging to a wire guy with one hand, Dick waited. Glennie signaled the engine room for slower speed, and the Grampus rounded neatly and pushed her nose past the tower of the other boat.

"There you are, Dick!" cried Matt.

The next instant Dick had leaped across the intervening stretch of water and had landed on the flat deck of the Pom.

Before his feet had struck the deck, however, Matt saw a Jap's head and shoulders push upward through the Pom's hatch. If there had been time to feel anything so useless as surprise, Matt would certainly have been taken all aback.

Captain Pons had said that only five Japs had comprised the crew which had palmed themselves off as Chilians. One of these five had been left in Lota, a prisoner. According to Matt's reckoning, that left only four of the yellow men in charge of the Pom. Where, then, did this extra Jap come in?
