14 BUREAU OF AMERICAN ETHNOLOGY 



Throufi^hoiit almost the entire year Mr. James Mooney, 

 ethuologist, was occupied in the office in compiling the 

 material for his study of Indian population covering the 

 whole territory north of Mexico from the first white occu- 

 pancy to the present time. By request of the Nebraska 

 State Historical Society he was detailed in January, 1911, 

 to attend the joint session of that body and the Mississippi 

 Valley Historical Association, at Lincoln, Nebraska, where 

 he delivered three princii^al addresses bearing particularly 

 on the method and results of the researches of the bureau 

 with the view of their application in local historical and 

 ethnological investigations. 



On June 4 Mr. Mooney started for the reservation of 

 the East Cherokee in North Carolina to continue former 

 studies of the sacred formulas and general ethnology of 

 that tribe, and was engaged in this work at the close of the 

 month. 



At the beginning of the fiscal year Dr. J. Walter Fewkes, 

 ethnologist, was in northern Arizona examining the great 

 cave pueblos and other ruins within the Navaho National 

 Monument. He found that since his visit in 1909 consider- 

 able excavation had been done by others in the rooms of 

 Betatakin, and that the walls of Kitsiel, the other large 

 cliff-ruin, were greatly in need of repair. Guided by resi- 

 dent Navaho, he visited several hitherto imdeseribed cliff- 

 dwellings and gathei-ed a fairly good collection of objects 

 illustrating prehistoric culture of this part of northern 

 Arizona, which have been deposited in the National ]\Iu- 

 seum. In order to facilitate the archeological work and to 

 make the a-egion accessible to students and visitors it was 

 necessary to break a wagon road from Marsh Pass through 

 the middle of the Navaho National ]\Ionument to the neigh- 

 borhood of Betatakin, and by this means the valley was 

 traversed with wagons for the fii"st time. 



On the return journey to Flagstaff, Doctor Fewkes vis- 

 ited the ruins in Nitsi, or AVest Canyon, and examined 

 Inscriptio?! House, a prehistoric cliff-dwelling of consider- 

 able size, hitherto undescribed, the walls of which are built
