Douglass.)] PRELIMINARY REPORT ON A VISIT TO THE NAVAHO NATIONAL MONUMENT, ARIZONA By JESSE WALTER FEWKES INTRODUCTION On the completion of the work of excavation and repair of Cliff Palace, in the Mesa Verde National Park, in southern Colorado, in charge of the writer, under the Secretary of the Interior, he was instructed by Mr. W. H. Holmes, then Chief of the Bureau of American Ethnology, to make an archeologic reconnaissance of the northern part of Arizona, where a tract of land containing important prehistoric ruins had been reserved by the President under the name Navaho National Monument. In the following pages are considered some of the results of that trip, a more detailed account of the ruins being deferred to a future report, after a more extended examination shall have been made.[1] Mention is made of a few objects collected, and recommendations are submitted for future excavation and repair work on these remarkable ruins to preserve them for examination by students and tourists. As will appear later, a scientific study of them is important, for they are connected with Hopi pueblos still inhabited, in which are preserved traditions concerning the ruins and their ancient inhabitants.
