The diverse meaning of terms in Zuñi architecture is no less significant of the diverse conditions and opposite directions of derivation of the Zuñi ancestry. If the aboriginal branch of the Zuñi were derived from the dwellers in the northern cliff towns, as has been assumed, then we would expect to find surviving in the names of such structural features of their pueblos as resulted from life in the cliffs linguistic evidence, as in the structures themselves material evidence, of the fact. Of this, as will presently be shown, there is an abundance. If the intrusive branch of the Zuñi ancestry were, as has also been assumed, of extreme southwestern origin, then we should expect to find linguistic evidence of a similar nature, say, as to the structural modifications of the cliff-dweller and round-town architecture which their arrival at and ultimate position in these towns might lead us to expect to find, and which in fact is to be abundantly traced in later Zuñi ruins, like those of the historic Seven Cities of Cibola. The conditions of life and peculiarities of building, etc., in the caves and cliffs, then in the round towns, have been commented on at some length in previous pages, and sufficiently described to render intelligible a presentation of this linguistic and additional evidence in regard to derivation from that direction; but it remains for me to sketch, as well as I can in brief, the more significant of such characteristics of the primitive Yuman house and village life as seem to bear on the additional linguistic and other evidence of derivation also from the opposite or Rio Colorado direction, for both clews should be presented side by side, if only for the sake of contrast.
