One fact is certain, the human bones, the walls protruding from the banks, and the grave found by Mr. E. K. Walters, are all above the layer of white ashes, charcoal, corncobs, and corrugated pottery found as a continuous seam along an extent of over 100 m.--327 ft.--from N. to S. Consequently, the walls and graves must have been built over these remains of a people which appears to have made indented and corrugated pottery alone, and consequently also the latter must be older in time than the former. It does not appear that the sedentary Indians of New Mexico ever made, within traditional and documentary times, any other than the painted pottery in greater or less degree of perfection. Even Gaspar Castaño de la Sosa, when he made his inroad into New Mexico in 1590, mentions at the first pueblo which he conquered: "They have much pottery,--red, figured, and black,--platters, caskets, salters, bowls.... Some of the pottery was glazed."[132] The corrugated and indented pottery, as I am assured by Sr. Vigil, is rarely met with over New Mexico, except at old ruined pueblos, and only when digging (en cavando).[133] I feel, therefore, justified in assuming it to have been the manufactured ware of a people distinct from the Pecos tribe or the pueblo Indians of New Mexico in general, and their predecessors in point of time. This pottery, however, is frequently met with among the cliff dwellings of the Rio Mancos and in Utah.[134] Its relation, then, to the painted pottery has, as far as I know, not yet been investigated.
