The North American Indian is by nature a symbolist, a mystic, and a philosopher. Like most aboriginal peoples, his soul was en rapport with the cosmic agencies manifesting about him. Not only did his Manidos control creation from their exalted seats above the clouds, but they also descended into the world of men and mingled with their red children. The gray clouds hanging over the horizon were the smoke from the calumets of the Gods, who could build fires of petrified wood and use a comet for a flame. The American Indian peopled the forests, rivers, and sky with myriads of superphysical and invisible beings. There are legends of entire tribes who lived in lake bottoms; of races who were never seen in the daytime but who, coming forth from their hidden caves, roamed the earth at night and waylaid unwary travelers; also of Bat Indians, with human bodies and wings, who lived in gloomy forests and inaccessible cliffs and who slept hanging head downward from outcroppings of rock. The red man's philosophy of elemental creatures is apparently the outcome of his intimate contact with Nature, whose inexplicable wonders become the generating cause of such metaphysical speculations.
