In the northern continent aboriginal America reached its highest development in three typical environments. The first of these regions centered in the valley of Mexico where dwelt the Aztecs, but it extended as far north as the Pueblos in Arizona and New Mexico. The special feature of the environment was the relatively dry, warm climate with the chief rainfall in summer. The Indians living in this environment were notable for their comparatively high social organization and for religious ceremonials whose elaborateness has rarely been surpassed. On the whole, the people of this summer rain or Mexican type were not warlike and offered little resistance to European conquest. Some tribes, to be sure, fought fiercely at first, but yielded within a few years; the rest submitted to the lordly Spaniards almost without a murmur. Their civilization, if such we may call it, had long ago seen its best days. The period of energy and progress had passed, and a time of inertia and decay had set in. A century after the Spaniards had overcome the aborigines of Mexico, other Europeans--French, English, and Dutch--came into contact with a sturdier type of red man, best represented by the Iroquois or Five Nations of central New York. This more active type dwelt in a physical environment notable for two features--the abundance of cyclonic storms bringing rain or snow at all seasons and the deciduous forest which thickly covered the whole region. Unlike the Mexican, the civilization of the Iroquois was young, vigorous, and growing. It had not learned to express itself in durable architectural forms like those of Mexico, nor could it rival the older type in social and religious organization. In political organization, however, the Five Nations had surpassed the other aboriginal peoples of North America. When the white man became acquainted with the Iroquois in the seventeenth century, he found five of their tribes organized into a remarkable confederation whose avowed object was to abolish war among themselves and to secure to all the members the peaceful exercise of their rights and privileges. So well was the confederation organized that, in spite of war with its enemies, it persisted for at least two hundred years. One of the chief characteristics of the Iroquois was their tremendous energy. They were so energetic that they pursued their enemies with an implacable relentlessness similar to the restless eagerness with which the people of the region from New York to Chicago now pursue their business enterprises. This led the Iroquois to torture their prisoners with the utmost ingenuity and cruelty. Not only did the savages burn and mutilate their captives, but they sometimes added the last refinement of torture by compelling the suffering wretches to eat pieces of flesh cut from their own bodies. Energy may lead to high civilization, but it may also lead to excesses of evil. The third prominent aboriginal type was that of the fishermen of the coast of
