Collier's New Encyclopedia (1921)
a natural object, one of a class taken by a tribe, a family, or a single person, and treated with superstitious respect as an outward symbol of an existing intimate unseen relation. The totem is considered as helpful to the man, who in his turn abstains from killing it if an animal, or eating it if a plant, and who often assimilates himself to it by wearing its skin or the like, or tattooing its picture on his body. The whole members of the clan who have a totem in common count themselves of one blood, and claim the totem as their common ancestor. The restriction on killing and eating it is absolute, and sometimes men are tabooed from touching or even looking at it under pain of expulsion from the tribe. Elabdeath or prate ceremonies connected with birth, marriage, and death point more closely to the identification of the man and the totem, and such ceremonies as those of the Australians at puberty are intended to initiate the youth into the restrictions that must be observed in sexual commerce.
Aiton's Encyclopedia (1910)
among the Indians of North America , a natural object, usually an animal, assumed as the token or emblem of a clan or family. A representation of the totem served to designate the members of the clan, much as emblems are used by members of the various fraternal orders. The totem of the Indian was pricked in the skin or on the clothing and upon weapons of the chase, domestic utensils, etc. In a way the figure of the clan totem was an idol, at least it is clear that it was regarded with reverence. The Indians of the Pacific coast set up totem poles, posts on which their totem was carved. A totem pole of this sort has been secured by the city of Seattle. Longfellow speaks of totem posts in Hiawatha. And they painted on the grave-posts-- Each his own ancestral Totem, Each the symbol of his household; Figures of the Bear and Reindeer, Of the Turtle, Crane, and Beaver, Each inverted as a token That the owner was departed.
