Whilst these improvements were being made in locks, the other parts of the gun were gradually approaching in lightness, strength, and accuracy of finish, to the modern standard. The most valuable improvement was the invention of the rifle barrel. It is mentioned by Pere Daniel, who wrote in 1693, as being then well known; but the time and place of its origin has never been ascertained. It was first employed as a military weapon by the Americans, in the Revolutionary war, and it is in their hands that it acquired its world-wide reputation.
It would be impossible, in an article like the present, to detail all the various attempts which have been made, during the last half century, to increase the efficiency of the rifle. The efforts of scientific men and mechanics have been constantly directed towards the invention of a gun which should fire, with the greatest possible rapidity, a number of times without reloading, and which should possess the indispensable requisites of safety, durability, and simplicity, both in construction and in use. Hitherto no invention has combined these advantages in a sufficient degree to supplant the common rifle.
In our opinion, these ends are all most simply and beautifully attained by the invention of Mr. Jennings. But of this our readers will be able to judge for themselves, by the above engravings and the directions for its use.
CARTRIDGES AND MACHINERY OF JENNINGS'S RIFLES.
Fill the magazine, on the top of the breech, with percussion pills or primings, and the tube, under the barrel, with the hollow cartridges containing gunpowder. Of these cartridges the tube will hold twenty-four. Place the forefinger in the ring which forms the end of the lever, e, and the thumb on the hammer, elevating the muzzle sufficiently to let the cartridge nearest the breech slip, by its gravity, into the carrier d; swing the lever forward, and raise the hammer which moves the breech-pin back, and the carrier up, placing the cartridge level with the barrel; pull the lever back, and thus force the breech-pin forward, and shove the cartridge into the barrel, by which motion a percussion priming is taken from the magazine by means of the priming-rack c, revolving the pinion which forms the bottom of the magazine, and it also throws up the toggle a, behind the breech-pin, thus placing the piece in the condition to be discharged by a simply upward pressure of the finger in the ring. After the discharge release the pressure and repeat the process.
In conclusion, the reader is invited to look at the engraving we have given of the first gun, and to compare it with the offspring of American ingenuity we have just described.
Fire-arms are the great pioneers which have opened a way for the progress of civilized man, and given him victory over the savage beasts and still more savage men who have opposed his course. Civilization has in its turn reacted upon fire-arms, and brought them to their present state of wonderful efficiency.
The heavy match-lock of three centuries ago was almost as dangerous to him who used it as to the enemy against whom it was directed. It would be almost impossible for a person to injure himself by the repeating rifle except by deliberate intention. Skilful military men advised the abandonment of the match-lock for the bow. A good marksman with the repeating rifle would kill a score of bowmen, before they could approach near enough to reach him with their arrows. The practised musketeer, in the reign of Elizabeth, could hardly fire his piece once in twenty minutes; the merest novice can fire the repeating rifle twenty times in one minute.
