10 BUEEAU OF AMERICAN ETHNOLOGY 



summary of the Indian wars, and notable epidemics within 

 the same region from the discovery. No similar investiga- 

 tion has ever before been attempted, even the official Indian 

 reports being incomplete as to identity of tribes and number 

 of Indians not directly connected with agencies. 



In January, 1910, by request of those organizations, 

 Mr. Mooney was designated to represent the Bureau of 

 American Ethnology at the joint meeting of the Mississippi 

 Valley Historical Association and the Nebraska State His- 

 torical Society, held at Lincoln, Nebraska, and delivered 

 several addresses, with particular reference to the utiliza- 

 tion of the methods and results of the Bureau in local 

 ethnologic and historical research. 



At the request of the Secretary of the Interior, Dr. J. 

 Walter Fewkes, ethnologist, continued the excavation and 

 repair of the prehistoric ruins in the Mesa Verde National 

 Park, in southern Colorado, begun in the previous year. 

 Doctor Fewkes commenced work on Cliff Palace in May, 

 1909, and completed the excavation and repair of this cele- 

 brated ruin in August. He then proceeded to northwestern 

 Arizona, and made a reconnoissance of the Navaho National 

 Monument, visiting and studying the extensive cliff and 

 other ruins of that section, knowledge of the existence of 

 which he had gained many years ago during his ethnological 

 researches among the Hopi Indians. At the close of this 

 investigation Doctor Fewkes returned to Washington and 

 prepared for the Secretary of the Interior a report on the 

 excavation and repair of Cliff Palace, which was published 

 by the Department of the Interior in November. A more 

 comprehensive illustrative report on the same ruins, giving 

 the scientific results of Doctor Fewkes's studies during the 

 progress of the excavation of Cliff Palace, was prepared for 

 publication as Bulletin 51 of the Bureau of American Eth- 

 nology and is now in press, forming a companion publication 

 to his description of Spruce-tree House, published earlier in 

 the fiscal year as Bulletin 41. Doctor Fewkes prepared also 

 a report on his preliminary researches in the Navaho National 

 Monument, which is in type and will be published as Bul- 

 letin 50. During the remainder of the winter and spring,
