There was no craft near us, and our surface speed is nearly twice that of our submerged, so I blew out the tanks and our whale-back came over the surface. All night we were steering south-west, making an average of eighteen knots. At about five in the morning, as I stood alone upon my tiny bridge, I saw, low down in the west, the scattered lights of the Norfolk coast. "Ah, Johnny, Johnny Bull," I said, as I looked at them, "you are going to have your lesson, and I am to be your master. It is I who have been chosen to teach you that one cannot live under artificial conditions and yet act as if they were natural ones. More foresight, Johnny, and less party politics--that is my lesson to you." And then I had a wave of pity, too, when I thought of those vast droves of helpless people, Yorkshire miners, Lancashire spinners, Birmingham metal-workers, the dockers and workers of London, over whose little homes I would bring the shadow of starvation. I seemed to see all those wasted eager hands held out for food, and I, John Sirius, dashing it aside. Ah, well! war is war, and if one is foolish one must pay the price. Just before daybreak I saw the lights of a considerable town, which must have been Yarmouth, bearing about ten miles west-south-west on our starboard bow. I took her farther out, for it is a sandy, dangerous coast, with many shoals. At five-thirty we were abreast of the Lowestoft lightship. A coastguard was sending up flash signals which faded into a pale twinkle as the white dawn crept over the water. There was a good deal of shipping about, mostly fishing-boats and small coasting craft, with one large steamer hull-down to the west, and a torpedo destroyer between us and the land. It could not harm us, and yet I thought it as well that there should be no word of our presence, so I filled my tanks again and went down to ten feet. I was pleased to find that we got under in one hundred and fifty seconds. The life of one's boat may depend on this when a swift craft comes suddenly upon you. We were now within a few hours of our cruising ground, so I determined to snatch a rest, leaving Vornal in charge. When he woke me at ten o'clock we were running on the surface, and had reached the Essex coast off the Maplin Sands. With that charming frankness which is one of their characteristics, our friends of England had informed us by their Press that they had put a cordon of torpedo-boats across the Straits of Dover to prevent the passage of submarines, which is about as sensible as to lay a wooden plank across a stream to keep the eels from passing. I knew that Stephan, whose station lay at the western end of the Solent, would have no difficulty in reaching it. My own cruising ground was to be at the mouth of the Thames, and here I was at the very spot with my tiny _Iota_, my eighteen torpedoes, my quick-firing gun, and, above all, a brain that knew what should be done and how to do it.
