The war in Europe, its causes and consequences; an authentic narrative of the immediate and remote causes of the war, with a descriptive account of the countries involved, including statistics of armies, navies, aeroplanes, dirigibles, &c., &c . yers launch theirtorpedoes from swiveling deck-tubes by means of compressed ships have tubes below the water line through which they arelaunched. A sort of trigger on the top of the torpedo is caught andthrown back as it leaves the tube, and this starts the engines. There-after, the torpedo is to all intents and purposes a self-contained sub-marine boat. AUTOMOBILE TORPEDOES 103 The devices that keep the torpedo true to its course and ata proper depth are of great ingenuity. The torpedo can he set so thatit will run either along the surface of the water or at any desireddepth, down to about twenty feet. The steering-gear that keeps ittrue in the vertical plane is based on the principle that the pressure ofwater increases with the depth. A spring is set to the known pressureof the water at the depth at which it is desired to run the it sink below that depth, the increased weight of the water willpress the spring back and thus open a valve that operates a small. Torpedo Boat Discharging a Torpedo steering-engine. Should the torpedo rise, the pressure will decreaseand the sjjring will force the valve in the opposite direction, thus actu-ating a corresponding turn of the rudder. A pendulum, free to swingin the longitudinal plane, checks sudden upward and, downward move-ments and over-application of rudder pressure by striking the valvemechanism when brought into j)lay. The torpedo is kept true to a straight-ahead course by a gyroscopicdevice, known as the Obry gear. The gyroscope tends stronglyto revolve always in the same plane. If the torpedo should veer, itwould throw the longitudinal axis of the torpedo to the right or theleft of the plane of the gyroscope, thus actuating stern rudders
