+501+. The employment of a sacred object as a badge or crest, a sign of tribal or clan position, is found, as is noted above,[853] in various parts of the world: in the Torres Straits islands, in the Aru archipelago (west of New Guinea), and in North America among the Iroquois, the Lenâpé (Delawares), the Pueblos, and perhaps among the Potawatamies. In these tribes, however, the rôle of the badge is relatively unimportant--it is employed for decorative purposes, but does not enter fundamentally into the organization of the clan or the tribe. In Northwest America, on the other hand, it is of prime significance both in decoration and in organization--it, to a great extent, takes the place occupied elsewhere by the totem, and it is not always identical with the eponymous object of the clan, though this may be an accidental result of shifting social relations (new combinations of clans, or a borrowing of a device from a neighbor). +502+. _The crest._ The origin of this function of the crest and its relation to the function of the totem is not clear; it may have arisen in different ways in different places, or different conceptions may have been combined in the same place. The decorative use is an independent fact, having no necessary connection with clan organization; the demand for decoration is universal among savages, and the employment of sacred objects for this purpose is natural. Figures of such objects are used, however, in magical procedures--abundantly, for example, in Central Australia--and it is conceivable that such use by a clan may have converted the totemic object into a symbol or device. The artistic employment of figures of sacred objects has been developed on the American Pacific Coast to a remarkable extent; the great poles standing in front of houses or erected in memory of the dead have carved on them histories of the relation of the family or of the deceased person to certain animals and events. These so-called totem poles presuppose, it is true, reverence for the sacred symbol, but the custom may possibly have grown simply out of artistic and historical (or biographical) motives.
