Report of the President 53 



During the year our reference file of photographs has been 

 increased by 2,745 prints, and 3,553 negatives have been 



added to the negative file. These numbers 

 Reference include 1,630 negatives of the Akeley African 



and Negatives expeditions deposited in the Museum by Mr. 



Carl E. Akeley, but they do not include nearly 

 7,000 negatives made by Mr. Herbert Lang of the American 

 Museum's Congo Expedition. The latter have not yet been 

 filed. To our collection of motion picture films the following 

 have been added: 700 feet of South American subjects, made 

 and presented by Mr. Algot Lange; 360 feet of American Bison 

 made in Yellowstone Park, presented by Mr. M. P. Skinner, and 

 6,000 feet made by the Barnes-Kearton Expedition across 

 central Africa, presented by Mr. James Barnes. The photo- 

 graphic work of the Museum has grown until it is impossible for 

 one photographer to do it, and consequently several thousand 

 prints and a considerable number of lantern slides were made 

 outside of the Museum by commercial photographers. The 

 following work, however, was actually done by the Museum 

 photographer during the year: 5,502 prints, 2,615 lantern 

 slides, 1,490 negatives, 17 enlargements and 9 transparencies. 

 These numbers, although large, give no adequate idea of the 

 difficulties overcome or of the tremendous amount of pains- 

 taking work accomplished. 



Administrative duties as Assistant Secretary of the Board 

 of Trustees have occupied the Curator to such an extent that 



he has given only casual attention to departmental affairs. 



The real burden of directing the details of the educational 

 work has rested, therefore, on the Assistant Curator, Dr. G. 

 Clyde Fisher, and the progress noted is a significant tribute to 

 his efficiency. The Museum Extension to the public libraries 

 and the development of the education for the blind have been 

 in charge of Miss Ann E. Thomas, who has also given valuable 

 assistance in the various lecture courses.
