utility, this work will constitute an Important contribution to 

 the sciences dealing with mankind. 



Field work was prosecuted in Alaska, Arizona, California, 

 Maine, New Mexico, New York, North Carolina, Virginia, 

 and Wisconsin, as well as in British Columbia and Ontario, 

 Canada, and in Lower California and Sonora, Mexico. Addi- 

 tional data were received from correspondents and collabora- 

 tors in other sections. 



One of the noteworthy expeditions of the year traversed 

 the arid regions of Arizona, Sonora, and Lower California 

 along new routes, and resulted in discovering the recent 

 extinction of the Tepoka Indians, in defining the western 

 boundary of the territory occupied by the Papagos, also in 

 the first scientific study of the Cocopas living in the Lower 

 Colorado River region. Among these Indians a collection 

 was made for the National Museum, portions of which were 

 subsequently used in the exhibit at the Pan-American Expo- 

 sition in Buffalo. The Cocopas were found to present vari- 

 ous features of interest both to scientific students and to 

 statesmen. The work of the expedition was facilitated by 

 several officers of the Republic of Mexico, including His 

 Excellency Sefior Don Manuel de Aspiroz, the ambassador 

 from Mexico to the United States, whose courtesy it is a 

 pleasure to acknowledge. An extensive archa?ologic recon- 

 naissance was made also through central and southeastern 

 Arizona, where various ruins of ancient habitations were 

 examined. Linguistic records of great value were obtained 

 by a collaborator among the Haida Indians in British 

 Columbia. 



Valuable collections were made or acquired during the 

 year — a typical series of stone implements from Georgia, a 

 collection of artifacts in stone and clay from southern Cal- 

 ifornia, the Cocopa collection already mentioned, and a series 

 of obsidian blades from California being most notable. 



As during previous years, numerous photographs of abo- 

 rigines were taken both in the field and from Indian delega- 

 tions visiting Washington, and toward the close of the year 

 a number of kinetoscope views, or motion pictures, were 

 obtained for purposes of study and record. 



The work in the office covered a wide range of topics per- 

 taining to the characteristics and products of the aborigines.
