As among the savages of the present day we find certain elementary mechanisms adapted to facilitate the production of fire, it is not impossible that these same means were practised at an early period of the human race. It would take a considerable time to set light to two pieces of dry wood by merely rubbing them against one another; but if a bow be made use of, that is, the chord of an arc fixed firmly on a handle, so as to give a rapid revolution to a cylindrical rod of wood ending in a point which entered into a small hole made in a board, the board may be set on fire in a few minutes. Such a mode of obtaining fire may have been made use of by the men who lived in the same epoch with the mammoth and other animals, the species of which are now extinct.
The first rudiments of combustion having been obtained, so as to serve, during the daytime, for the purposes of warmth and cooking food, and during the night, for giving light, how was the fire to be kept up? Wood from the trees that grew in the district, or from those which were cast up by the currents of the rivers or sea; inflammable mineral oils; resin obtained from coniferous trees; the fat and grease of wild animals; oil extracted from the great cetaceans;—all these substances must have assisted in maintaining combustion, for the purposes both of warmth and light. The only fuel which the Esquimaux of the present day have either to warm their huts or light them during the long nights of their gloomy climate, is the oil of the whale and seal, which, burnt in a lamp with a short wick, serves both to cook their food and also to warm and illumine their huts.
Even, nowadays, in the Black Forest (Duchy of Baden), instead of candles, long splinters of very dry beech are sometimes made use of, which are fixed in a horizontal position at one end and lighted at the other. This forms an economical lamp, which is really not to be despised.
We have also heard of the very original method which is resorted to by the inhabitants of the Faroe Isles in the northern seas of Europe, in order to warm and light up their huts. This method consists in taking advantage of the fat and greasy condition of the young Stormy Petrel (Mother Carey's Chicken), so as to convert its body into a regular lamp. All that is necessary is to draw a wick through its body, projecting at the beak, which when lighted causes this really animal candle to throw out an excellent light until the last greasy morsel of the bird is consumed.
This bird is also used by the natives of the Isles as a natural fuel to keep up their fires and cook other birds.
Whatever may have been the means which were made use of by primitive man in order to procure fire, either the simple friction of two pieces of wood one against the other, continued for a long time, the bow, or merely a stick turning round rapidly by the action of the hand, without any kind of mechanism—it is certain that the acquisition of fire must be classed amongst the most beautiful and valuable discoveries which mankind has made. Fire must have put an end to the weariness of the long nights. In the presence of fire, the darkness of the holes and caverns in which man made his first retreat, must have vanished away. With the aid of fire, the most rigorous climates became habitable, and the damp which impregnated the body of man or his rough garments, made of the skin of the bear or some long-haired ruminant, could be evaporated. With fire near them, the danger arising from ferocious beasts must have much diminished; for a general instinct leads wild animals to dread the light and the heat of a fire. Buried, as they were, in the midst of forests infested with wild beasts, primitive men might, by means of a fire kept alight during the night, sleep in peace without being disturbed by the attacks of the huge wild beasts which prowled about all round them.
Fire, too, gave the first starting-point to man's industry. It afforded means to the earliest inhabitants of the earth for felling trees, for procuring charcoal, for hardening wood for the manufacture of their rudimentary implements, and for baking their primitive pottery.
Thus, as soon as man had at his disposal the means for producing artificial heat, his position began to improve, and the kindly flame of the hearth became the first centre round which the family circle was constituted.
Ere long man felt the need of strengthening his natural powers against the attacks of wild beasts. At the same time he desired to be able to make his prey some of the more peaceable animals, such as the stag, the smaller kinds of ruminants, and the horse. Then it was that he began to manufacture weapons.
He had remarked, spread about the surface of the ground, certain flints, with sharp corners and cutting edges. These he gathered up, and by the means of other stones of a rather tougher nature, he broke off from them pieces, which he fashioned roughly in the shape of a hatchet or hammer. He fixed these splinters into split sticks, by way of a handle, and firmly bound them in their places with the tendons of an animal or the strong stalks of some dried plant. With this weapon, he could, if he pleased, strike his prey at a distance.
