It was so practical that it became the form of gun for all uses; thus gunmaking began to be a big industry. Invented early in the seventeenth century, it was used by the hunters and soldiers of the next two hundred years. Old people remember when flint-locks were plentiful everywhere. In fact, they are still being manufactured and are sold in some parts of Africa and the Orient. One factory in Birmingham, England, is said to produce about twelve hundred weekly, and Belgium shares in their manufacture. Some of the Arabs use them to this day in the form of strange-looking guns with long, slender muzzles and very light, curved stocks. Caps and Breech-Loaders. Primers were tried in different forms called “detonators,” but the familiar little copper cap was the most popular. No need to describe them. Millions are still made to be used on old-fashioned nipple guns, even in this day of fixed ammunition. [Illustration: THE FIRST REMINGTON RIFLE] Then came another great development, the breech-loader. From Henry VIII to Cartridges. Breech-loaders were hardly new. King Henry VIII of England, he of the many wives, had a match-lock arquebus of this type dated 1537. Henry IV of France even invented one for his army, and others worked a little on the idea from time to time. But it was not until fixed ammunition came into use that the breech-loader really came to stay--and that was only the other day. You remember that the Civil War began with muzzle-loaders and ended with breech-loaders. Houiller, the French gunsmith, hit on the great idea of the cartridge. If you were going to use powder, ball and percussion primer, to get your game, why not put them all into a neat, handy, gas-tight case? Simple enough, when you come to think of it, like most great ideas. But it required good brain-stuff to do that thinking. A Refusal and What Came of It. Two men, a smith and his son, both named Eliphalet Remington, in 1816, were working busily one day at their forge in beautiful Ilion Gorge, when, so tradition says, the son asked his father for money to buy a rifle, and met with a refusal. The boy set his wits to work. Looking around the forge, he picked up enough scrap iron to make a gun barrel, and with this set to work to make a rifle for himself. At that time gun barrels were made, not by drilling the bore out of a solid rod of metal, but by shaping a thick, oblong sheet of metal around a rod the size of the bore, and lapwelding the edges. When the rod was withdrawn, there was your barrel. It took him several weeks to work out this job and get it right, but he succeeded. He had no tools to cut the rifling. There was a gunsmith in Utica, and he walked there, fifteen miles over the hills, to have his barrel finished. The gunsmith was so impressed by the boy and his accomplishment that, after rifling the barrel, he fitted it with a lock. Then when Remington fitted on a wooden stock his weapon was ready.
