It means that the Naval Officer of the future will regard machinery, mechanical work, and mechanical problems as his “bread and butter.” He will think no more of handling machinery of any sort than the ordinary mortal does of riding a bicycle; guns, gun-mountings, torpedoes, and electrical instruments and machines he will regard as special types, but differing no whit in principle from the primitive stock. Mystery will disappear. At present it is an unfortunate thing that departmental jealousy leads the members of each and every department of the Service to make a mystery of their particular speciality. The Gunnery Lieutenant, Torpedo Lieutenant, Engineer, and Marine Officer each resent discussion by “outsiders” of any point in connection with their speciality, as a piece of unwarrantable presumption, with the result that each knows all about his own job, and pursues it diligently, taking care not to poach on anybody else’s preserves, but without any regard as to whether the Service might not gain in efficiency by a little more co-operation and collaboration. From one point of view they are right in being exclusive, because they know that no one else knows anything about their work, and therefore discussion with “outsiders” is mere waste of breath, but in future all this will be changed. Specialities will disappear; the Naval Officer of the future will see no greater difference between a gun-mounting and a torpedo, than an Engineer sees between the main engines and the feed pump. However, although specialities will disappear, it will always be necessary to have “experts” in each department. We shall still require our Lieutenants G., T., and E.; but as at the present time when a Lieutenant G. is promoted to Commander he drops the G., so also it seems logical to conclude that the future Lieutenant E. on promotion to Commander should drop the E. It is absolutely safe to predict that the Naval Officer of 50 years hence will smile when he reads that his forefathers had to have an officer of Commander’s rank appointed to a ship solely for charge of the main engines. Foreigners gasp when they hear that Lieutenants of two or three years standing command our destroyers; in other navies destroyers are usually commanded by Captains de Corvette; and then we smile when we remember youngsters like Lieutenant Rombulow-Pearse of the “Sturgeon,” who rescued the crew of the sinking “Decoy” in a gale of wind, with only his small whaler to help him, and with the loss of only one man, who disappeared nobody knows how. The ideal complement of officers of the future therefore will be: 1 Captain, 1 Commander, 1 Lieutenant G., 1 Lieutenant E., 1 Lieutenant T., 1 Lieutenant M., 1 Lieutenant N., 1 Lieutenant P., and as many other watchkeepers as necessary.
