In Northwestern California the more important ceremonies can always be held only at certain spots, and the performance of ceremonies of the same name always varies somewhat at different places. The performers do not represent mythological or other characters and do not imitate animals. The more important dances last at least a number of days, not infrequently as many as ten. The dances are held either out-doors or in certain sacred houses, which are however not different from the ordinary living-house of the region except through their traditionary and ceremonial associations. The essential religious portion of the ceremony consists of the actions gone through by a priest, with sometimes one or two assistants. The more important part of his procedure is the recital of one of the sacred formulae so characteristic of the region. This formula relates specifically to the exact locality at which the dance is held, and therefore often varies considerably from spot to spot. The formula is regarded as it were as private property, and its knowledge is sufficient to institute the priest in his capacity. The public portions of the ceremony, such as the dancing, are practically dissociated from this purely religious element. The dancers are mostly young men without any knowledge of the ceremony other than of the simple dance-step and songs. The paraphernalia which they wear belong neither to them nor to the priests, but to wealthy men of the tribe, for whom the occasion is an all-important opportunity for the display of their wealth, which consists in large part of the dancing regalia, and the possession of which is the chief factor toward their social prominence. The dancers appear in from two to five parties, representing neighboring villages, each of which is aided by the wealthy men of other villages; and these parties vie with each other primarily in the display of their regalia. The most important ceremonies are the Deerskin dance and the Jumping dance, which are held either annually or biennially, the former always out-doors, the latter at some places out-doors, sometimes in boats, at others in-doors. The purpose of both dances, which where both are practiced are usually given in close succession, is the good of the world. Earthquake and disease are prevented and a food supply insured. Very little of the sacred formulae and accompanying ritual, and nothing in the remainder of the dance, has however any specific reference to this purpose. A third, minor ceremony, the Brush dance, completes the series of public ceremonies in this region, the remaining dances being held only on occasion of war, a girl's puberty, or the initiation of a shaman. Even the Brush dance is not fully of a tribal character, inasmuch as it is performed for the benefit of a single individual, a sick child, although it is participated in by an entire village with the assistance of visitors from others, and though there seems to be a
