In the ritual of the installation of chiefs in all the many addresses and chants and songs, each of the two constituent organic members, the father and the mother sides, is addressed as a single individual. In the famous so-called six songs of the mourning and installation council, which are so dramatically sung by a chief who represents the dead chief or chiefs to be resurrected, each of the two constituent persons is addressed, but in the fifth song, the totality, the league as a unity is addressed as a person, to whom is sung this farewell song of the departing chief. This is done evidently to secure the departure of the ghost in peace. Again, the lamenting cry of “hai′i, hai′i,“ which is so tediously recurrent in all the chants and songs, but one, of the mourning and installation council, is employed, it is said, in order to console the spirits or spirit of the dead. The reason for using this particular cry is that it is reputed to be that made by spirits when moving from place to place. But it was believed that should this cry be omitted in the rituals the displeasure of the departed spirits would be manifested in an epidemic of diseases affecting the spine and the head. The duties and obligations of the clan or sisterhood of clans of a father to the clan of his children were by the founders of the league made a part of the functions of the male member, or sisterhood of tribes, in the organic structure of the league. In like manner the duties and obligations of the clan or sisterhood of clans of a mother to the clan or sisterhood of clans of the father of the children were made a part of the functions of the female member, or sisterhood of tribes, in the organic structure of the league. Thus the two constituent members of the highest order in the structure of the league were the female group of two tribes and the male group of three tribes, respectively representing the mother and the father sides, the female and male principles, the whole representing the union of fatherhood and motherhood for the promotion of the life force and welfare of the community.
