The Wonder Book Of Knowledge Part 8

After that it was merely a matter of improvement. The arrow-end was apt to slip from the string until some one thought to notch it. Its head struck with such force that the early hunter decided to give it a sharp point, shaped from a flake of flint, in order that it might drive deep into the body of a deer or bear.

[Ill.u.s.tration: WINDING THE SHAFT]

But, most of all, it must fly true and straight to its mark. Who of all these simple people first learned to feather its shaft? Was it some one who had watched the swift, sure-footed spring of a bushy-tailed squirrel from branch to branch? Possibly, for the principle is the same. At all events with its feathers and its piercing point the arrow became the most deadly of all missiles, and continued to be until long after the invention of firearms.

A Great Variety.

It is interesting to see how many different forms of bow were used. The English had a six-foot "long bow" made of yew or ash, in a single straight piece, that shot arrows the length of a man's arm. The Indians had bows only forty inches on the average, since a short bow was easier to handle in thick forests. They used various kinds of wood, horn or even bone, such as the ribs of large animals. These they generally backed with sinew.

Sometimes they cut spiral strips from the curving horns of a mountain sheep, and steamed them straight. Then they glued these strips together into a wonderfully tough and springy bow. Once in a while they even took the whole horns of some young sheep, that had not curved too much, and used the pair just as they grew. In this case each horn made one-half of the bow, and the piece of skull between was shaped down into a handle.

This gave the shape of a "Cupid's Bow," but it could shoot to kill.

As to Arrows.

The arrows were quite as important, and their making became a great industry with every race. This was because so many must be carried for each hunt or battle.

Who is not familiar with the chipped flint arrow-heads that the farmer so often turns up with his plow as a relic of the period when Americans were red-skinned instead of white? These arrow-heads have generally a shoulder where the arrow was set into the shaft, there to be bound tightly with sinew or fiber. Many of them are also barbed to hold the flesh.

A Shooting Machine.

But the age of machinery was coming on. Once in a while there were glimpses of more powerful and complicated devices to be seen among these simple arms.

A new weapon now came about through warfare. Man has been a savage fighting animal through pretty much all his history, but while he tried to kill the other fellow, he objected to being killed himself.

Therefore he took to wearing armor. During the Middle Ages he piled on more and more, until at last one of the knights could hardly walk, and it took a strong horse to carry him. When such a one fell, he went over with a crash like a tin-peddler's wagon, and had to be picked up again by some of his men. Such armor would turn most of the arrows. Hence invention got at work again and produced the cross-bow and its bolt. We have already learned how the tough skin of animals brought about the bow; now we see that man's artificial iron skin caused the invention of the cross-bow.

What It Was.

What was the cross-bow? It was the first real hand-shooting machine. It was another big step toward the day of the rifle. The idea was simple enough. Wooden bows had already been made as strong as the strongest man could pull, and they wished for still stronger ones--steel ones. How could they pull them? At first they mounted them upon a wooden frame and rested one end on the shoulder for a brace. Then they took to pressing the other end against the ground, and using both hands. Next, it was a bright idea to put a stirrup on this end, in order to hold it with the foot.

Still they were not satisfied. "Stronger, stronger!" they clamored; "give us bows which will kill the enemy farther away than he can shoot at us! If we cannot set such bows with both arms let us try our backs!"

So they fastened "belt-claws" to their stout girdles and tugged the bow strings into place with their back and leg muscles.

"Stronger, stronger again, for now the enemy has learned to use belt-claws and he can shoot as far as we. Let us try mechanics!"

So they attached levers, pulleys, ratchets and windla.s.ses, until at last they reached the size of the great siege cross-bows, weighing eighteen pounds. These sometimes needed a force of twelve hundred pounds to draw back the string to its catch, but how they could shoot!

And Now for Chemistry.

Human muscle seemed to have reached its limit, mechanics seemed to have reached its limit, but still the world clamored, "Stronger, stronger!

How shall we kill our enemy farther away than he can kill us?" For answer, man unlocked one of the secrets of Nature and took out a terrible force. It was a force of chemistry.

[Ill.u.s.tration: DEER-STALKING WITH THE CROSS-BOW

This compact arm with its small bolt and great power was popular with many sportsmen.]

Who first discovered the power of gunpowder? Probably the Chinese, although all authorities do not agree. Strange, is it not, that a race still using cross-bows in its army should have known of explosives long before the Christian Era, and perhaps as far back as the time of Moses?

Here is a pa.s.sage from their ancient Gentoo Code of Laws: "The magistrate shall not make war with any deceitful machine, or with poisoned weapons, or with cannons or guns, or any kind of firearms." But China might as well have been Mars before the age of travel. Our civilization had to work out the problem for itself.

Playing with Fire.

It all began through playing with fire. It was desired to throw fire on an enemy's buildings or his s.h.i.+ps, and so destroy them. Burning torches were thrown by machines, made of cords and springs, over a city wall, and it became a great study to find the best burning compound with which to cover these torches. One was needed which would blaze with a great flame and was hard to put out.

Hence the early chemists made all possible mixtures of pitch, resin, naphtha, sulphur, saltpeter, etc.; "Greek fire" was one of the most famous.

What Two Monks Discovered.

Many of these were made in the monasteries. The monks were pretty much the only people in those days with time for study, and two of these shaven-headed scientists now had a chance to enter history. Roger Bacon was the first. One night he was working his diabolical mixture in the stone-walled laboratory, and watched, by the flickering lights, the progress of a certain interesting combination for which he had used pure instead of impure saltpeter.

Suddenly there was an explosion, shattering the chemical apparatus and probably alarming the whole building. "Good gracious!" we can imagine some of the startled brothers saying, "whatever is he up to now! Does he want to kill us all?" That explosion proved the new combination was not fitted for use as a thrown fire; it also showed the existence of terrible forces far beyond the power of all bow-springs, even those made of steel.

Roger Bacon thus discovered what was practically gunpowder, as far back as the thirteenth century, and left writings in which he recorded mixing 11.2 parts of the saltpeter, 29.4 of charcoal, and 29 of sulphur. This was the formula developed as the result of his investigations.

Berthold Schwartz, a monk of Freiburg, studied Bacon's works and carried on dangerous experiments of his own, so that he is ranked with Bacon for the honor. He was also the first one to rouse the interest of Europe in the great discovery.

And then began the first crude, clumsy efforts at gunmaking. Firearms were born.

The Coming of the Matchlock.

Hand bombards and culverins were among the early types. Some of these were so heavy that a forked support had to be driven into the ground, and two men were needed, one to hold and aim, the other to prime and fire. How does that strike you for a duck-shooting proposition? Of course such a clumsy arrangement could only be used in war.

Improvements kept coming, however. Guns were lightened and bettered in shape. Somebody thought of putting a flash pan for the powder, by the side of the touch-hole, and now it was decided to fasten the slow-match, in a movable c.o.c.k, upon the barrel and ignite it with a trigger. These matches were fuses of some slow-burning fiber, like tow, which would keep a spark for a considerable time. Formerly they had to be carried separately, but the new arrangement was a great convenience and made the matchlock. The c.o.c.k, being curved like a snake, was called the "serpentine."

[Ill.u.s.tration: AN UNEXPECTED MEETING

The "Kentucky Rifle" with its flint-lock was accurate, but had to be muzzle-charged.]

The Gun of Our Ancestors.

Everybody knows what the flint-lock was like. You simply fastened a flake of flint in the c.o.c.k and snapped it against a steel plate. This struck off sparks which fell into the flash-pan and fired the charge.

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.
