The preparation of the illustrations for the publications 
of the bureau, the making of photographs of the members 
of delegations of Indians visiting Washington, and the 
developing and printing of negatives made by the staff of 
the bureau during the prosecution of their field work have 
been in charge of Mr. DeLancey Gill, illustrator, assisted 
successively by Mr. Walter Stenhouse and Mr. Albert 
Sweeney. In addition the numerous photostat copies of 
manuscripts and books, aggregating about 2,500 exposures, 
have been made under Mr. Gill’s supervision, as elsewhere

tribes, 79 photographic exposures were made; 92 negatives 
of ethnologie subjects were required for reproduction as 
illustrations; 512 negatives made by the members of the 
staff in the field were developed and 881 prints made there-

Indians and 627 for publication, exchange, and special dis-
