(M289) The principle of mimicry is implanted so deep in human nature and has exerted so far-reaching an influence on the development of religion as well as of the arts that it may be well, even at the cost of a short digression, to illustrate by example some of the modes in which primitive man has attempted to apply it to the satisfaction of his wants by means of religious or magical dramas. For it seems probable that the masked dances and ceremonies, which have played a great part in the social life of savages in many quarters of the world, were primarily designed to subserve practical purposes rather than simply to stir the emotions of the spectators and to while away the languor and tedium of idle hours. The actors sought to draw down blessings on the community by mimicking certain powerful superhuman beings and in their assumed character working those beneficent miracles which in the capacity of mere men they would have confessed themselves powerless to effect. In fact the aim of these elementary dramas, which contain in germ the tragedy and comedy of civilized nations, was the acquisition of superhuman power for the public good. That this is the real intention of at least many of these dramatic performances will appear from the following accounts, which for the sake of accuracy I will quote for the most part in the words of the original observers. (M290) A conspicuous feature in the social life of the Indian tribes of North-Western America are the elaborate masked dances or pantomimes in which the actors personate spirits or legendary animals. Most of them appear designed to bring before the eyes of the people the guardian spirits of the clans. “Owing to the fact that these spirits are hereditary, their gifts are always contained in the legend detailing their acquisition by the ancestor of a clan. The principal gifts in these tales are the magic harpoon which insures success in sea-otter hunting; the death bringer which, when pointed against enemies, kills them; the water of life which resuscitates the dead; the burning fire which, when pointed against an object, burns it; and a dance, a song, and cries which are peculiar to the spirit. The gift of this dance means that the protégé of the spirit is to perform the same dances which have been shown to him. In these dances he personates the spirit. He wears his mask and his ornaments. Thus the dance must be considered a dramatic performance of the myth relating to the acquisition of the spirit, and shows to the people that the performer by his visit to the spirit has obtained his powers and desires. When nowadays a spirit appears to a young Indian, he gives him the same dance, and the youth also returns from the initiation filled with the powers and desires of the spirit. He authenticates his initiation by his dance in the same way as his mythical ancestor did. The obtaining of the magical gifts from these spirits is called _lokoala_, while the person
