The idea that most of the submarines come inshore at night and lie at the bottom in bays is quite a wrong one--perhaps at the beginning of the war, when the boats were smaller, they may have done so; but the larger ones for choice avoid the shallower water and keep out in deeper channels. Safety to themselves prompts such procedure, for they are quite alive to the danger of nets and explosive bombs dropped from the air and surface of the water. When homeward bound and nearing their own shores they often lie at the bottom all night and wait for daylight before proceeding for fear of encountering English patrols or destroyers. With their own war craft they have special flag signals by day and Morse flashes by night. The larger U's have wireless installation by which in code they can communicate with each other, but their range of transmission is short. The sanitary arrangements below were good and much the same as on any liner. A petty officer was in charge of the sanitation, who also was first aid ambulance man, had charge of the medicine chest, and when required acted as a gunner--quite a handy man. There were two good lavatories on board, effete matter being expelled by force pumps at any time. Other than drinking water there was scarcity of fresh water for domestic uses, so there was no chance of a fresh water bath, another of the drawbacks experienced, although sponging off in cold salt water is at all times refreshing. There was a variety of books to read, comic and other papers, among them two English papers nearly three weeks old; a gramophone and several records, so that we had music, singing, and occasionally dancing for exercise' sake, but no smoking below, which was strictly forbidden and was perhaps the greatest hardship of all. There was thus a little gayety on board to relieve the monotony, although, truth to tell, I found the voyage an exciting one and my shipmates seemed merry enough. In fact, I was surprised at myself getting used so quickly to the new life, and am bound to confess that I was no more worried about what was going on above the surface of the water than I had previously been on my own boat about what takes place at any minute from under the water.
