that each of the Guiana tribes makes its feather head-dresses of special colors; and Martins has the following regarding the Brazilian Indians: "Commonly all the members of a tribe, or a horde, or a family, agree to wear certain ornaments or signs as characteristic marks." Among these are various ornaments of feathers on the head, pieces of wood, stones, or shells, in the ears, the nose, and lips, and especially tattoo marks. VAIN DESIRE TO ATTRACT ATTENTION Thus we see that an immense number of mutilations of the body and alleged "decorations" of it are not intended by these races as things of beauty, but have special meanings or uses in connection with protection, war, superstition, mourning, or the desire to mark distinctions between the tribes, or degrees of rank within one tribe or horde. Usually the "ornamentations" are prescribed for all members of a tribe of the same sex, and their acceptance is rigidly enforced. At the same time there is scope for variety in the form of deviations or exaggerations, and these are resorted to by ambitious individuals to attract attention to their important selves, and thus to gratify vanity, which, in the realm of fashion, is a thing entirely apart from--and usually antagonistic to--the sense of beauty[94]. At Australian dances various colors are used with the object of attracting attention. Especially fantastic are their "decorations" at the corroborees, when the bodies of the men are painted with white streaks that make them look like skeletons. Bulmer believed that their object was to "make themselves as terrible as possible to the beholders and not beautiful or attractive," while Grosse thinks (65) that as these dances usually take place by moonlight, the object of the stripes is to make the dancers more conspicuous--two explanations which are not inconsistent with each other.
