+530+. _Secret societies._ It is a common custom in the lower tribes to keep the sexes separate and to distinguish between the initiated and the uninitiated. There are often men's houses in which the young unmarried males are required to live.[880] Women and boys are forbidden to be present at ceremonies of initiation when, as in some instances, the secrets of the tribe are involved. Thus there arise frequently secret associations of males, who conduct tribal affairs. But these associations are not voluntary--all initiated men belong to them perforce--and they are not divorced from totemic relations. The real voluntary society is of a quite different character. In general, in its most developed form, it ignores differences of age, sex, and clan. There are, however, diversities in the constitution of the various organizations that may be called voluntary;[881] conditions of membership and functions vary.

The clan government by the old men, of which a simple form exists in Central Australia, has passed into, or is represented by, a society of men that undertakes to maintain order, exact contributions, and provide amusements for the people. The Dukduk of the Bismarck Archipelago,[882] the Egbo of Old Calabar, and the Ogboni of Yoruba,[883] to take prominent examples, are police associations that have managed to get complete control of their respective communities and have naturally become instruments of oppression and fraud. They have elaborate ceremonies of initiation, are terrible to women and uninitiated males, and religion usually enters only casually and subordinately into their activities, chiefly in the form of magical ceremonies. A partial exception, in regard to this last point, occurs in the case of the Areoi society of Tahiti, which, as it is the best-organized society in Polynesia, is also the most tyrannical, and the broadest in its scope; its members enjoy not only a large share of the good things of this life, but also the most desirable positions in the future life.[884]
