One target is pointed out to us which represents the iron casing of the vulnerable portions of a torpedo boat, consisting of engine-room, boilers, and coal-bunkers. These compartments have been riddled again and again. Even a service-rifle bullet can penetrate one side, and a shell of the smallest size will go through both, for torpedo boats are not very heavily built.
HIRAM S. MAXIM AND THE MAXIM MACHINE GUN.
Statisticians inform us that the entire loss of life in wars between so-called civilised countries from the year 1793 down to 1877 had reached the enormous amount of four million four hundred and seventy thousand. To many persons these figures convey a sad and salutary lesson. But, leaving the sentimental part of the subject aside, all will readily unite in admiring the wonderful mechanism which makes the Maxim Machine Gun an engine of terrible destructiveness. Stanley provided himself with this formidable weapon, to be used defensively in the expedition on which he started for the relief of Emin Bey. It obtained a gold medal at the Inventions Exhibition, and has been approved of, if not actually adopted, by many governments.
Its rate of firing--770 shots a minute--is at least three times as rapid as that of any other machine gun. It has only a single barrel, which, when the shot is fired, recoils a distance of three-quarters of an inch on the other parts of the gun. This recoil sets moving the machinery which automatically keeps up a continuous fire at the extraordinary rate of 12 rounds a second. Each recoil of the barrel has therefore to perform the necessary functions of extracting and ejecting the empty cartridge, or bringing up the next full one and placing it in its proper position in the barrel, of cocking the hammer, and pulling the trigger. As long as the firing continues, these functions are repeated round after round in succession. The barrel is provided with a water jacket, to prevent excessive heating; and is so mounted that it can be raised or lowered or set at any angle, or turned horizontally to the left or to the right. The bore is adapted to the present size of cartridges; and the maximum range is eighteen hundred yards. The gun can therefore be made to sweep a circle upwards of a mile in radius.
