"Depends! What was the cargo you had aboard the vessel? What damage was done?"

"Done! How?" asked Larry, curious to learn how much the Commander knew himself.

"By the bomb placed by our agent—a clever trick that!" said the officer; "a clever man Heinrich Hilker! But perhaps you don't know him."

Whereat Larry sniffed harder, but, feeling it wise to make no answer, stood staring round him at the various wheels and quadrants and instruments which filled almost every available inch of the centre of the vessel.

"Well then," demanded the officer, when a minute had passed, "what is your report?"

Larry looked under the peak of his hat into his eyes, regarding every portion of the officer down to his feet, screwed up his lips, smiled that enigmatical smile of his and answered not a word. Then, after a long pause, he tapped the officer on the shoulder.

"See here, Mr. Officer," he said, "you've taken us in what you call fair fighting, and we're prisoners; let it stand at that. You wouldn't expect to give away what had happened in your own case, supposing positions were reversed. Then don't expect it of an American. Play the game, and give us something to eat and drink, for we're well-nigh famished, and something strong would send the blood through us after being chilled in the water."

Maybe the German officer in command of this German submarine was of a type different from those who have commanded the majority of these under-water vessels, and who seem to have stooped to the murder of so many helpless individuals. He looked Larry up and down, stared hard at Jim, and stepped a pace closer to Bill, as if attracted by his youthful appearance and anxious to interrogate him. Then he clapped his hands, gave a sharp order, and saw the trio led back to the compartment in which they had been incarcerated. There a sailor brought them food and steaming coffee, adding to each cup some rum, which helped to warm them wonderfully. A little later he brought them dry clothing and took their wet garments away from the compartment; then, as if anxious to treat them well, he produced blankets and mattresses, upon which Larry and his two friends were soon stretched.

Indeed they slept for hours, worn out with their exertions of the previous night and with the struggle they had waged during the day which had just passed. Nor were their dreams unhappy. They fell asleep mindful of the unfortunate position in which they found themselves, but buoyed up by the memory of their success in helping to beach the vessel and her valuable cargo.
