There are two considerations that make the public performance of the more important privileges a matter of the greatest moment. In the first place, a man must clearly indicate his right to its performance by recounting the origin myth that it dramatizes, and by tracing his personal connection with the originator of the privilege. In the second place, he must be careful to distribute at least as much property as has already been distributed in his family, in connection with the public presentation of the privilege. If it is at all possible, he will try to exceed the record, so as to add to the public prestige not only of himself and his immediate family, but of the privilege itself. Should he fail in either of these essential respects, he is shamed. Hence, an important potlatch is not to be lightly undertaken. It requires much careful thought and preparation, and it necessitates the gathering of enough wealth to pay for all the services rendered by singers and other assistants, to present substantial gifts to the guests, and to feed the crowd of men, women and children that are present at the ceremony.
