"I say nothing," he answered. "I have told about the torpedo. But I tell you nothing more. It is all for Nippon, for my beloved country."

"That's the way with those fellows," said Matt disappointedly. "He wouldn't speak another word even if he was tortured. I'm surprised that he said what he did about the torpedo. Turn him over to Pons and the captain of the port, Glennie, and let's row out into the bay and see if we can learn anything about the fate of the Grampus."

Matt's face was haggard with fear and anxiety. He had had a bad half hour, since the explosion of the torpedo and the disappearance of the Grampus, and his face reflected the intensity of his feelings.

Glennie turned away from the prisoner and stepped to the edge of the wharf. He paused there for a moment, rigid as a statue, his eyes wandering over the surface of the bay.

Motor Matt, wondering at his manner, likewise directed his gaze off over the water. As he did so, Glennie recovered his wits abruptly and gave vent to an exultant yell.

"Hurrah!" he roared, jerking off his cap and waving it. "What's the matter with the motor boys, Matt? We've had our worry all for nothing!"
