14 Speaking broadly, spring and summer were seasons for gathering food, autumn for secular entertainments, and winter for religious ones. Despite a certain insecurity, due largely to raids by hostile tribes, life was rather pleasant and easy on this coast, even for the slaves. RELIGION The Pacific Coast natives believed that birds, animals, and fish possessed extraordinary powers, and that in addition there were other supernatural beings haunting the woods and the waters, and controlling the phenomena of nature. Thus far they agreed with other Indians. They differed, however, in imagining that some of these spirits played favourites by attach- ing themselves to individual Indian ‘‘Houses’’; and that a spirit, suddenly taking possession of some man or woman belonging to its House, could produce an illness only dispelled by an impersonation of that spirit in a ritual dance. Such “‘seizures”’ commonly recurred each winter, so that the natives spent nearly every evening from late December until mid-March in religious dances. At other seasons the spirit guardian was supposed to remain quiescent, though it might aid its protégé in a special emergency.

At one performance a weirdly painted dancer, with gleaming wolf’s tusks protruding from his mouth, leaped and pirouetted about the floor while the audience frenziedly roared his song
