The Neolithic man sought an abode farther away from the main highway—the river. In cliffs towering above the river bed—sometimes away from streams altogether, he scooped out a cave similar to the ones occupied by his ancestors. Thus in many countries remains are found of a race of cliff-dwellers. In ancient Greece, for example, have been found evidences of people living thus, and Indians in Mexico and Arizona three thousand years later were discovered in similar dwellings.
With a settled life, and cultivation of the soil, man frequently was forced to provide a home for himself. The material from which he made it depended upon the resources of the locality. In Egypt and Babylonia, sun-baked mud huts afforded the simplest, least expensive structures, both in point of time and labor. Among pastoral tribes, tents formed of animal skins sewed together were easiest to provide. This was the usual shelter also of the American Indians and other hunting tribes. The Laplander found cakes of ice suited for his home, while man in the tropics quickly constructed a shelter from the huge palm leaves, available on every hand.
"Of all places for studying construction of huts, Africa is the very best. There one may see samples of everything that can be thought of in the way of circular houses; built of straw, sticks, leaves, matting; of one room or of many; large or small; crude or wonderfully artistic and carefully made. They may be permanent constructions to be occupied for years or temporary shelter for a single night; they may consist of frameworks made of light poles over which are thrown mats or sheets of various materials and which after using can be taken apart, packed away, and transported."[2]
From lightly built, temporary dwellings, it was but a short step to the more substantial, more enduring ones. Stone houses, dwellings made of timber and of brick, as the country afforded, replaced the earlier homes, and when written records bring the full light of knowledge upon the life of nations, in the matters of constructing dwelling places, several peoples had become proficient.
Food.
It would be difficult to discover any plant or animal life which had not served at some period for food. Primitive man knew nothing about harmful plants, and only by long experience did he learn to avoid such as worked him woe. No insect or animal is so repulsive but that it has been appropriated by the food-hunter in some age and country, and things today which we would refuse in time of distress were used as a matter of course by earlier people.
Nature supplied acorns, berries, roots, fruits, fish and plenty of game. All these articles were at first eaten in their native state. When fire became well known, cooked foods grew in favor. It is supposed that these were at first roasted. To suspend meat over a fire or make a large opening in the ground, cover the floor with stones, heat these very hot, then remove the fire and bake the food, these are the most primitive—as well, perhaps, as the most satisfactory—ways known to us. Boiling was probably a later method, and this was not done as we boil food today. Rather, stones were heated very hot and tossed into kettles of water. In this way the water was brought to a boiling point and the food cooked.
Cultivated Plants.
Before men learned to cultivate plants and to domesticate animals, subsistence was always an uncertain matter. They roamed about in one vicinity until nature could no longer supply their needs, then left the exhausted land to recover itself while new territory afforded means for satisfying hunger. After fire became such a potent factor, as we have seen, a fixed abode was desirable. It fell to the lot of women to stay and tend the hearth. Shut off from the long expeditions undertaken by men, they soon learned to make as much as possible of the space around about their homes. Sticks were sometimes placed around plants or bushes to protect them from the careless step until their fruits matured. Occasionally plants were dug up and replanted nearer the hut. The garden and grain field were but natural results of this spirit of husbanding the stores provided by mother earth.
While women were the first to domesticate plants in the simple way just indicated, not much came of it until men adopted the idea and carried it further. With sharp sticks they scratched the soil and with the help of animals they trod in the seeds. Irrigation was sometimes needed—as in Egypt—to insure good crops. Thus from slight beginnings developed the agriculture of the world. With reasonable labor and painstaking, the tiller of the soil could be sure of a living for himself and his family, and before historic records illumine the life of several nations, farming was well understood. Indeed it is safe to say that until very recent times methods followed by tillers of the soil in quite a number of countries advanced very little upon those of the prehistoric man.
