The reader is reminded that from the nature of the work at Cliff Palace very few specimens can be expected from it in the future, and that so far as the minor antiquities are concerned the objective material from this ruin is now all deposited in public museums or in private collections. Additional specimens can be obtained, however, from other ruins near it which will throw light on the culture of Cliff Palace. It is appropriate, therefore, to point out, at the very threshold of our consideration, that a continuation of archeological work in the Mesa Verde National Park is desirable, as it will add to our knowledge of the character of prehistoric life in these canyons. The next work to be undertaken should be the excavation and repair of a Mesa Verde pueblo. The extensive mounds of stone and earth on the promontory west of Cliff Palace have not yet been excavated, and offer attractive possibilities for study and a promise of many specimens. Buried in these mounds there are undoubtedly many rooms, secular and ceremonial, which a season's work could uncover, thus enlarging indirectly our knowledge of the cliff-dwellers and their descendants.[2] [Footnote 2: A few holes that have been dug here and there in these mounds have brought to light sections of walls with good masonry, but no excavations that could be called extensive or scientific have yet been attempted on this site. The excavation of these mounds might reveal a pueblo like Walpi, and a comparison of objects from them with those from Cliff Palace would be important in tracing the relationship of cliff-dwellings and pueblos.] The writer considers it an honor to have been placed in charge of the excavation and repair of Cliff Palace, and takes this occasion to express high appreciation of his indebtedness to both the Secretary of the Smithsonian Institution and the Secretary of the Interior for their confidence in his judgment in this difficult undertaking. Maj. Hans M. Randolph, superintendent of the Mesa Verde National Park, gave assistance in purchasing the equipment, making out accounts, and in other ways. During the sojourn at Cliff Palace the writer was accompanied by Mr. R. G. Fuller, of the Peabody Museum of Harvard University, a volunteer assistant, who contributed some of the photographs used in the preparation of the plates that accompany this report. The writer is indebted also to Mr. F. K. Vreeland, of Montclair, New Jersey, for several fine photographs of Cliff Palace taken before the repairing was done.
