* * * * * Since the war began, British submarines have penetrated into every harbour and river mouth on the coast of Germany. One day a British boat in the mouth of a German river was seen by the enemy. At once she went under; but though she lay on the silt at the bottom, she had not more than five feet of water above her. Almost any patrol boat could have hit her and destroyed her had her whereabouts been known; but somehow the Germans missed her. They meant to catch her, however, and began to sweep the river with a wire trawl. Before long the commander of the submarine heard the trawl rasping along his hull. He sat and listened, expecting every moment that it would catch on something, and reveal him to the Germans working above. The suspense was enough to turn a man's hair gray. Happily, the trawl slid off the hull, and the danger passed. At nightfall the submarine made her way into the open sea, and finally reached harbour safely. * * * * * The following story has been told of a fight between a British submarine and a Zeppelin. One day a boat came to the surface, and found herself right underneath a Zeppelin that was flying only a few yards above the sea. The commander could not see the sky, only the shining bulge of the airship. Luckily he was not under the "stinging end" of the monster. Immediately he sank till his decks were awash, and went away to windward, so that the Zeppelin had to follow him with the wind in its teeth. Then he sent a man to the gun on deck. The waves were washing over the submarine, and the man was nearly drowned; but he hung on, and whenever he saw a chance, fired a shot at the airship, which by this time was dropping bombs. One of his shots got home, and the Zeppelin was obliged to steer to leeward and give up the chase. A fortnight later she was seen with a patch on the place where she had been hit. * * * * *
