Leaving Germany she was stored for a twelve-weeks' cruise; when I joined her she had provisions only for a few more days as prisoners previously captured had consumed some of them, hence their anxiety to get rid of the remaining ones sent off in a hurry in the _Wanderer's_ boat. The original stores were preserved pork and beef, vegetables, tinned soups, fruit, raisins, biscuits, butter, marmalade, milk, tea, and coffee. Prior to sinking one ship they had commandeered eggs, fresh meat, butter, vegetables, and some liquor to afford variety to the larder; so that the bill of fare was varied and there was no stinting of rations. Any cooking was done on an electric stove. II--STORY OF LIFE ON THE SUBMARINE The U was driven by petrol, but they said colza or benzoline or any kind of machine oil not too thick could be used, and if this could be replenished from any captured ship so much the better. I would have liked to know about any of the supply ships which undoubtedly have a secret rendezvous with these submarines, and also about land bases in some of the neutral countries so-called, but this information was, of course, denied me. The living quarters were small but comfortable, officers having separate small cabins and the crew bunks with narrow alley way in between. Ventilation was surprisingly good, pipes for the purpose running all through the boat, foul air being extracted by exhaust and fresh air driven in four or five times a day for half an hour at a time while on the surface. More than once I remained below for more than twelve hours and did not suffer from headache or symptoms due to bad air. Sometimes we were submerged for four hours, sometimes longer, once for close on fourteen hours, but I felt little inconvenience. The officers stated that up to twenty-four hours of continual submersion they were fairly comfortable; after that, for six hours, it was uncomfortable, and subsequently became intolerable, due to the "sweating" from the framework of the boat, which rendered the clothing damp. To obviate this, leather suits were worn mostly during prolonged submersion, and this process was perhaps the most disagreeable experience of all. For purposes of ventilation, therefore, and in order that the crew might remain in good health, as well as for necessary locomotion, the U remained as much as possible on the surface both day and night.
