Turning to another continent, we may find an example of adaptability of a more elaborate ceremony. The Navaho are in the main an Athapascan people who have wandered down to the sterile plains of New Mexico and Arizona. There, ages ago, they came into contact with the more settled Pueblo tribes. The researches of American anthropologists show the practical identity of certain of their religious rituals with those of their Pueblo neighbours. It would seem that these rituals have been taken over from the latter. This is only natural, seeing that the Navaho came down from the north with an undeveloped culture and organization into a country where new needs were experienced and a higher civilization was met with. But in taking over the rituals they have applied them to purposes different from those of their original performers. The chief aim of the ceremonies as used among the Pueblo tribes is to obtain fertility, and the condition of fertility is rain. This is clear from the use made of corn-meal and corn-pollen. “Pollen is the symbol of fertility, and the rite at bottom is for rain. The Navaho took over the use of the corn and the pollen together with the other features; but the corn no longer served its previous {151} purpose as a prayer for rain and the ripening of the crops: it was used for the cure of disease.”[151.1] The Dene or Athapascans, of which stem the Navaho are a branch, are a people of migratory hunters. Agriculture would be foreign to them. Their principal ceremonies are concerned with the conjuration of evil spirits and the cure of diseases, which are usually ascribed to the spirits. It was natural that when they borrowed the ceremonies of a settled agricultural community they should imbue them with their own ideas. In their hands the cure of disease “became the fundamental feature of the borrowed rites. A ceremony intended for rain-making would naturally need some alteration in order to serve as a cure of disease.”[151.2] And it has received it. The fact that they have been able so to adapt the rites probably points to some want of definiteness in the form of the rites at the time they were borrowed.
