I have always had more or less doubt as to the use of the name Enchanted Mesa for Katzímo and was glad to see that you use the Indian word for it.... I have come to the conclusion that those who hold that the Pueblo once existed on its top have not made their point, archaeologically speaking. That they visited the top goes without saying, but to my mind the evidence is more mythical than scientific, that any considerable number lived on Katzímo in prehistoric times. The same story is also told by the Navajo of the settlement upon the top of Ship Rock and I believe is one of those legends which are not based wholly upon facts, or at any rate cannot be proven. Chapter XII SOCIAL ORGANIZATION That the present town-building tribes are the descendants of the ancient peoples is indicated by tradition, by skeletal evidence, and by material culture. The past connects with the present without perceptible break and the implements and utensils of to-day are, save for the intrusive elements of white civilization, those of the past.—W. H. HOLMES. The Southwest is more remarkable for its puzzles than for its positive data. The problems presented by its social organization are of supreme interest but our knowledge of the data is exceedingly imperfect.—GOLDENWEISER. By reason of their geographic position, the pueblos were the natural channel through which passed the culture from the south to more northern areas. This culture, of whatever sort, they transmuted by their own endowment into something distinctive and characteristic of themselves. Kroeber puts it happily: Throughout, it was a flow of things of the mind, not a drift of the bodies of men: of culture, not of populations. The radiation was ever northward, counter to the drifts of the migrations which had begun thousands of years before and which, in part, seem to have continued to crowd southward even during the period of northward spread of civilization.[142] If we must feel that the Southwest learned from Mexico “how to grow and weave cotton, to irrigate, to build in stone, to obey priests,” we are at the same time impressed by an intrinsic difference in its development and practice from that of Mexico, as we see it in the Pueblo civilization.
