four illustrative of the tribes mentioned and the others of the Iro- 

 quois, the Navaho, the Seminoles, the Chippewa, the Samoans and 

 the Hawaiians. In addition to these, there are a large number of 

 aboriginal objects and several synoptic series desigTied to represent 

 the development of the knife, the saw, the European and American 

 ax, the spindle, the shuttle and fire-making apparatus. Fifty-two 

 lantern slides of Museum exhibits in the department of anthro- 

 pology were also made for use in a stereomotorgraph. 



Investigations relative to the material culture of the Hopi as 

 exemplified in the collections were conducted by the curator of the 

 division, Dr. "Walter Hough. This work is an elaboration of the 

 catalogues of the late James Stevenson, extended by the subsequent 

 information acquired by the curator both in museum and field re- 

 search. He also made a special study of the effect of the discovery 

 of fire-making methods on the early distribution of man, the results 

 of which have been prepared for publication. Dr. Gudmud Hatt, of 

 Copenhagen, made a study of the arctic clothing in the collection- 

 Other distinguished ethnologists from abroad who visited the 

 Museum were Dr. K. R. Marett, Dr. ^Y. H. R. Rivers, Mr. E. Sidney 

 Hartland and Miss Adele Breton, of England; and Dr. F. von 

 Luschan, of Berlin, Germany.
