“That’s the way to swat ’em, eh, matey?” remarked Bill with grisly joy as we were cleaning away the wreckage. “I say it is, Bill,” I made reply. CHAPTER X--A SIGNALMAN ON A SUBMARINE Don’t think for a moment that Germany was the only country that had a fleet of submarines. The reason that her U-boats came to be so well known was because they had torpedoed the _Lusitania_ and sunk helpless ships right and left no matter who was on them or what they carried. England and France had fleets of submarines, too, but as their warships had blockaded Germany’s ports there was nothing to torpedo. And when we declared war on the Kaiser, Uncle Sam began to build submarines just as he did chasers, merchant ships and everything else. Except airplanes, did you say? There was no such fizzle made of building submarines as for a time was made of building airplanes in the beginning of the war. Within a short time after we got started our Navy Department was able to turn out a brand-new submarine every two weeks. Think of it! Once the kind and the size of the submarine we needed had been agreed upon by our naval experts, that is, _standardized_ as it is called, machines and jigs were made by which each part was stamped out of a solid sheet of metal, and this was done, not in one or a dozen factories, but in hundreds of factories scattered all over the country and each of which made a single part. These parts were shipped to docks at various ports on the Atlantic seaboard and there artificers of all kinds were ready to assemble them, that is, to put them together. Thus it was that in two weeks after the ore was mined it was made into parts, assembled and the submarine was ready for its perilous cruise. While the building of submarines was thus speeded up there was another factor that made for their efficiency as a destructive engine of war which was just as important as the boats themselves and that was the crews to man them. Aye, and there was the rub, for a crew could not be trained for this highly specialized work in less than two months’ time and sometimes it took three or four months. Because the submarine job was considered an extra-hazardous one, volunteers were called for to man the boats and as an inducement for bluejackets to do so a good _bonus_, that is, extra pay was offered. Now Bill Adams knew all about submarines, as I think I told you before, for he had worked for the _Holland Submarine Boat Company_ long before the world-war started. “Let’s me and you go to it, matey,” he said, in one of his bursts of patriotism; “it isn’t quite as soft a snap as we’ve got on this here chaser but we gets more time ashore and then we helps our Uncle Sammy. Besides I’ve made up me mind to buy me mother a flivver; all the washladies in our neighborhood is ridin’ to and from work in them baby land-tanks of Mr. Ford’s, and I guess what they can do she can do, eh, matey?”
