"For the matter stands thus. If merchantmen--which can at the same time be U-Boats--may not be sunk without warning, then according to the laws and formalities of sea warfare the 'Deutschland' has rendered the English blockade futile. For I should like to see the German U-Trader that would allow an English patrol vessel to approach near enough to examine her! "Or supposing she is not searched. Then, in that case, merchant traders _can_ be sunk without warning--English traders likewise. And thus the rights of warfare will be evenly balanced once more by means of a peaceful, unarmed U-Boat trader. And this, my men, is where the enormous significance of our 'Deutschland' lies." Thereupon I concluded my speech, which was by far the longest I had ever made. * * * * * The fine weather still continued. The barometer remained steady, the air was dry and clear. We were gradually approaching the latitudes in which fine weather is the rule at that time of the year. The warmth of the sun's rays began to be felt, and our thoughts turned towards refreshment. This was provided us by our "wave-bath," a discovery of the observation engineer, Herr Kiszling, who otherwise showed no interest in anything but his beloved engines. For these he was full of the most touching and undeviating solicitude. Often, during a heavy sea, when all the deck hatches were closed, he would suddenly appear through the conning-hatch and push hastily through into the "bath-tank," regardless of the exigencies of higher navigation in process there. When the officer on duty looked round, annoyed at the disturbance, there was our sturdy Kiszling, in his oldest oilskins, leaning over the side of the dripping deck--filled with care for the welfare of his engines, trying to get a glimpse of the exhaust. At the same time he must see if the ignition was working properly, if the heart-beats of his engines were carrying out their functions, and if the explosions were quite regular. He was wrapped up in his beloved machinery and lived on its rhythmical music. He noticed at once the least irregularity in its working, and spared no trouble in getting to the bottom of it. It must have been during one of these special tours of his, which were by no means without danger, over the rounded slippery side-deck, that the inspiration came to him. In brief, he opened to us the joyful possibility of the "wave-bath." In order to understand this, it is first necessary to know the construction of the upper part of the "Deutschland." Above the cylindrical hull, on the sides of which are the submersion tanks and oil bunkers, rises the outer ship, which gives the vessel its real ship form.
