BEGINNINGS OF CIVILIZATION IN AMERICA

America Was Peopled from the Old World.—The origin of the people of America has been the subject of perennial controversy. Gradually, however, as the studies of the human race and their migrations have increased, it is pretty well established that the one stream of migration came from Asia across a land connection along the Aleutian Islands, which extended to Alaska. At an early period, probably from 15,000 to 20,000 years age, people of the Mongoloid type crossed into America and gradually passed southward, some along the coast line, others through the interior of Alaska and thence south. This stream of migration continued down through Mexico, Central America, South America, and even to Patagonia. It also had a reflex movement eastward toward the great plains and the Mississippi valley. There is a reasonable conjecture, however, that another stream of migration passed from Europe at a time when the British Islands were joined to the mainland, and the great ice cap made a solid bridge to Iceland, Greenland, and possibly to Labrador. It would have been possible for these people to have come during the third glacial period, at the close of the Old Stone Age, or soon after in the Neolithic period. The traditions of the people on the west coast all state their geographical origin in the northwest. The traditions of the Indians of the Atlantic coast trace their origins to the northeast.

The people of the west coast are mostly of the round-headed type (brachycephalic), while those of the east coast have been of the long-headed type (dolichocephalic). The two types have mingled in their migration southward until we have the long heads and the round or broad heads extending the whole length of the two continents. Intermingled with these are those of the middle derivative type, or mesocephalic. From these sources there have developed on the soil of America, the so-called American Indians of numerous tribes, each with its own language and with specialized physical and mental types. While the color of the skin has various shades, the coarse, straight black hair and brown eyes are almost general features of the whole Indian race.

At different centres in both North and South America, tribes have become more or less settled and developed permanent phases of early civilization, strongly marked by the later Neolithic cultures. In some exceptional cases, the uses of copper, bronze, and gold are to be noted. Perhaps the most important centres are those of the Incas in Peru, the Mayas, Aztecs, and Terra-humares of Mexico, the cliff-dwellers and Pueblos of southwestern United States, the mound-builders of the Mississippi valley, and the Iroquois nation of northeastern United States and Canada. At the time of the coming of the Europeans to America, the Indian population in general was nomadic, in the hunter-fisher stage of progress; but many of the tribes had tentatively engaged in agriculture, cultivating maize, squashes, and in some cases fruits. Probably the larger supply of food was from animals, birds, fish, and shell-fish, edible roots and grains, such as the wild rice, and fruits from the native trees in the temperate and tropical countries. The social organization was based upon the family and the tribe, and, in a few instances, a federation of tribes like that of the Iroquois nation.

The Incas of Peru.—When the Spaniards under Pizarro undertook the conquest of the Peruvians, they found the Inca civilization at its highest state of development. However, subsequent investigations discovered other and older seats of civilization of a race in some ways more highly developed than those with whom they came in contact. Among the evidences of this ancient civilization were great temples built of stone, used as public buildings for the administration of religious rights [Transcriber's note: rites?], private buildings of substantial order, and paved roads with numerous bridges. There were likewise ruins of edifices apparently unfinished, and traditions of an ascendent race which had passed away before the development of the Incas of Pizarro's time. In the massive architecture of their buildings there was an attempt to use sculpture on an elaborate scale. They showed some skill in the arts and industries, such as ornamental work in gold, copper, and tin, and the construction of pottery on a large scale. They had learned to weave and spin, and their clothing showed some advancement in artistic design.

In agriculture they raised corn and other grains, and developed a state of pastoral life, although the llama was the only domesticated animal of service. Great aqueducts were built and fertilizers were used to increase the productive value of the soil. The dry climate of this territory necessitated the use of water by irrigation, and the limited amount of tillable soil had forced them to use fertilizers to get the largest possible return per acre.
