The highest type of friendship is the relation of “brother-friend” or “life-and-death friend.” This bond is between man and man, is usually formed in early youth, and can only be broken by death. It is the essence of comradeship and fraternal love, without thought of pleasure or gain, but rather for moral support and inspiration. Each is vowed to die for the other, if need be, and nothing is denied the brother-friend, but neither is anything required that is not in accord with the highest conceptions of the Indian mind. III. CEREMONIAL AND SYMBOLIC WORSHIP Modern Perversions of Early Religious Rites. The Sun Dance. The Great Medicine Lodge. Totems and Charms. The Vapor-Bath and the Ceremonial of the Pipe. The public religious rites of the Plains Indians are few, and in large part of modern origin, belonging properly to the so-called “transition period.” That period must be held to begin with the first insidious effect upon their manners and customs of contact with the dominant race, and many of the tribes were so influenced long before they ceased to lead the nomadic life. The fur-traders, the “Black Robe” priests, the military, and finally the Protestant missionaries, were the men who began the disintegration of the Indian nations and the overthrow of their religion, seventy-five to a hundred years before they were forced to enter upon reservation life. We have no authentic study of them until well along in the transition period, when whiskey and trade had already debauched their native ideals. During the era of reconstruction they modified their customs and beliefs continually, creating a singular admixture of Christian with pagan superstitions, and an addition to the old folk-lore of disguised Bible stories under an Indian aspect. Even their music shows the influence of the Catholic chants. Most of the material collected by modern observers is necessarily of this promiscuous character. It is noteworthy that the first effect of contact with the whites was an increase of cruelty and barbarity, an intensifying of the dark shadows in the picture! In this manner the “Sun Dance” of the Plains Indians, the most important of their public ceremonials, was abused and perverted until it became a horrible exhibition of barbarism, and was eventually prohibited by the Government.
