"No—by God! and I would do it gladly." The Lieutenant's face worked, and he scowled as he glanced astern. "I would wish that every ship of every convoy carried women."

The Captain laughed almost genially. "It is easy to see you are not a Prussian," he said. "It does not matter whether you like or dislike a thing. All that counts is whether or not it is to the advantage of the State. So the Roman World-Empire was made. Myself, I doubt if killing women pays us; there is this talk now of the boycott of Germany after the war. They add time to the boycott for every time we fire on ships that are helpless, and the boycott is to be by sailors. I would laugh at such a threat if it was from any others, but sailors are not to be laughed at. They are likely to mean what they say. It is as I said: if we had fought to the West and to the sea, no man would have dared to threaten us with a sea-boycott now."

"But even with our small Navy we have held the English checked. It is not our Navy that is lacking. What is it, then?"

"It is the Navy. It should have been as big as the English Fleet. And the men—Gott! Müller. I tell you, if we had done the Zeebrugge attack ourselves, and I had been there, I would feel that my honour and the Navy's honour was safe, that we could stop and make peace. I would be proud to die on such a service, and I envy the Englishmen we buried when it was over."

"But this is—Herr Capitan, you talk as if you were an Englander——"

The Captain whirled on him, his eyes sparkling dangerously. "Dummkopf!" he said. "Report me if you like. I hate the English and I love my Fatherland, but report me if you like. Ach! You may report me in Hell, too; for I know—I know——"

He stopped suddenly and tilted back his head to listen. The First Lieutenant shrank back from him, his mouth open and his hands feeling for the periscope support. A faint murmur of sound came down wind from the fleecy cloud-banks to the west. The Captain jumped to the opening of the conning-tower and stood, impatient and anxious by the lip, until his lieutenant had slipped and scrambled half-way down the ladder.

Then he jumped down himself, pulling the lid to after him. Simultaneously there came a rush and roar of air from venting tanks, the stem of the boat rose very slightly as her bow-gun went under, and in twenty seconds the submarine was gone, and the bubbles and foam of her passage were fading into the level blue of the empty sea. A minute later she showed a foot of periscope a cable's length away, and a small airship topped the western horizon and came slowly along towards her. The periscope vanished again, and forty feet below the surface the captain watched a gauge needle beside the periscope creep round its dial inch by inch till it quivered and steadied at the forty-metre mark.

"Diving hands only. Fall out the rest. Remain near your stations. Lower the periscope." The First Lieutenant barked out a repetition of each order as the Captain spoke. There was a shuffling of feet, some guttural conversation that spoke of a flicker of curiosity among the men of the crew, and then all was quiet but for the hum of motors and the occasional rattle of gearing as the hydroplane wheels were moved. The Captain moved forward to the wardroom, removing his scarf and heavy pilot-cloth coat as he walked. "Order some food, Müller," he said. "I'm hungry—that airship was farther ahead of them than usual." He threw himself down in a long folding-chair and stretched out his sea-booted legs. "I won't come up to look now until I hear them. Relieve the listeners every half-hour, Müller. I want to have good warning. We should hear a big convoy like this at twenty miles to-day." The curtain rings clashed and a seaman spoke excitedly as he entered. The Captain nodded and reached out to the table for his coffee-cup. "Just the bearing we expected," he said, "but if they sound as faint as he says there's time to get something to eat first."
