A study of any large collection of decorated Pueblo ware, ancient or modern, will show many modifications of this broken line, a number of which I shall discuss more in detail when pottery ornamentation is considered. A design so distinctive and so widespread as this must certainly have a symbolic interpretation. The concentric spirals with a broken line, the Hopi say, are symbols of the whirlpool, and it is interesting to find in the beautiful plates of Chavero's _Antigüedades Mexicanas_ that the water in the lagoon surrounding the ancient Aztec capital was indicated by the Nahuatl Indians with similar symbols. OBJECTS FOUND AT PALATKI AND HONANKI The isolation of these ruins and the impossibility of obtaining workmen, combined with the brief visit which I was able to make to them, rendered it impossible to collect very many specimens of ancient handiwork. The few excavations which were made were limited almost wholly to Honanki, and from their success I can readily predict a rich harvest for anyone who may attempt systematic work in this virgin field. We naturally chose the interior of the rooms for excavation, and I will say limited our work to these places. Every chamber was more or less filled with débris--fragments of overturned walls, detached rock from the cliff above, dry alkaline soil, drifted sand, dust, and animal excreta. In those places where digging was possible we found the dust and guano so dry and alkaline that it was next to impossible to work for any length of time in the rooms, for the air became so impure that the workmen could hardly breathe, especially where the inclosing walls prevented ventilation. Notwithstanding this obstacle, however, we removed the accumulated débris down to the floor in one or two chambers, and examined with care the various objects of aboriginal origin which were revealed. In studying the specimens found in cliff-houses due attention has not always been given to the fact that occupants have oftentimes camped in them subsequently to their abandonment by the original builders. As a consequence of this temporary habitation objects owned by unrelated Indians have frequently been confused with those of the cliff-dwellers proper. We found evidences that both Honanki and Palatki had been occupied by Apache Mohave people for longer or shorter periods of time, and some of the specimens were probably left there by these inhabitants. The ancient pottery found in the rooms, although fragmentary, is sufficiently complete to render a comparison with known ceramics from the Verde ruins. Had we discovered the cemeteries, for which we zealously searched in vain, no doubt entire vessels, deposited as mortuary offerings, would have been found; but the kind of ware of which they were made would undoubtedly have been the same as that of the fragments.
