APPENDIX 4 
REPORT ON THE BUREAU OF AMERICAN ETHNOLOGY 
Sir: I have the honor to submit the following report on the 
researches, office work, and other activities of the Bureau of Ameri- 
can Ethnology during the fiscal year ended June 30, 1926, conducted 
in accordance with the act of Congress approved April 22, 1925. 
The act referred to contains the following item: 
American ethnology: For continuing ethnological researches among the 
American Indians and the natives of Hawaii, including the excavation and 
preservation of archeologic remains, under the direction of the Smithsonian 
Institution, including the necessary employees and the purchase of necessary 
books and periodicals, $57,160. 
In pursuance of the requirements for the excavation and preserva- 
tion of ruins contained in the above item, considerable work has 
been done in the region near Flagstaff, Ariz. Arizona shows many 
evidences of a prehistoric aboriginal population and is a State par- 
ticularly favorable to the study of prehistoric ruins. Thus far very 
few ruins have been excavated in northern Arizona and very scanty 
material has been obtained for a study of the objects illustrating the 
former culture of this region. 
Research in this line was inaugurated by the bureau in 1907 at 
Casa Grande and has been continued in successive years at the Mesa 
Verde National Park, Colo. Formerly walls of ruins were destroyed 
in the search for small specimens, such as pottery, and thus work of 
great archeological value was lost. The method adopted by some 
institutions of burying the walls after objects have been extract-d 
from the rooms, while intended as a means of preservation, is not 
satisfactory. The Bureau of American Ethnology, however, when 
the walls are not so mutilated that they can not be repaired, has 
endeavored to preserve them for future students. 
SYSTEMATIC RESEARCHES 
The chief of the bureau has headed an expedition to determine 
the western extension of the pueblo area in Arizona, where com- 
paratively little attention had been given to the character of the 
sedentary life of the Indians in prehistoric times. This includes the 
region west of the Little Colorado River which is archeologically a 
terra incognita. The site chosen by the chief to be excavated is
