It is considered as by no means improbable that the good shooting of the German ships was largely traceable to the excellence of their range-finders and the special training of those who used them. Whether it is true or not that France and England have succeeded since the war in making optical glass equal to that of Jena, there is no doubt that the latter was superior in the first years of the war. The German ships unquestionably had more accurate range-finders than did the British, and it is also known now that the Germans took great care in testing the eyesight of the men employed to handle these instruments, and that much attention was given to their training. It is believed that upon these simple points alone, rather than upon the use of a highly complicated system of control, the admitted excellence of German gunnery was based. There is no reason to believe that they had anything better than the British for laying down the "rate of change," and keeping the enemy under fire once he had been straddled. Although it was known to the British sailor in a general sort of way that the Germans only spent a comparatively small part of their time aboard their ships, the tangible evidence of this remarkable state of affairs--in the vast blocks of barracks at Wilhelmshaven and the very crude, inadequate living quarters in even the most modern of the ships searched--gave him only less of a shock, and aroused in him only less contempt, than did the filth and indiscipline of the German sailors. The German officer who assured one of the searching parties that their ships were made "to fight in, not to live in," told the literal truth, and it only accentuates the bitter irony of the fact that, when finally they refused to fight, they had to begin to be lived in willy-nilly.
