War Activities 39 



two of these recreational lectures have been completed and loaned 

 to the Y. M. C. A. — "Camera Hunting for Whales" by Roy Chap- 

 man Andrews and "Bird Life on an Antarctic Island" by Robert 

 Cushman Murphy. Two others, "Through the Brazilian Wilderness 

 with Colonel Roosevelt" by George K. Cherrie, and "Some of My 

 Mascots" by Ernest Harold Baynes, are nearly completed, and two 

 by Carl E. Akeley on "African Big Game" are in course of preparation. 



The third plan of cooperation with the Y. M. C. A. is to loan two- 

 reel sets of the best motion pictures in the Museum under the title of 

 "American Museum Exploration Series." These will include selected 

 portions of the motion pictures taken by Roy Chapman Andrews on 

 the Museum's Asiatic Zoological Expedition and the films secured by 

 the Crocker Land Expedition in the Arctic. 



At the request of Mrs. Henry R. Hoyt of the Ladies' Social Wel- 

 fare Committee of the Y. M. C. A., guides have been furnished for 

 groups of sailors on shore-leave from United States naval vessels in 

 the waters near New York. Such groups visit the Museum every 

 Saturday afternoon, and are conducted through the exhibition halls. 

 The Museum is indebted to Miss Annie E. Lucas who has generously 

 given her services as docent on the occasions of these visits. 



One sign of growth of the Museum as a whole is seen in the ever 

 increasing demands for photographic work — illustrations for scientific 

 publications, for The American Museum Journal, the Public Infor- 

 mation Committee, newspapers, magazines, and 

 photographic special writers, and lantern slides for the educa- 

 work tional work of the Museum have fully occupied 



the time of our two photographers. 



Museum photography offers peculiar difficulties, and much of 

 the work requires a surprisingly large amount of time. To make satis- 

 factory illustrations for The American Museum Journal, for example, 

 is more than simple photography — more than merely making a nega- 

 tive and a print. For the purposes of artistic illustration, a greater 

 or less amount of manipulation on the part of the photographer is 

 necessary to produce the desired result. 



Photographic illustrations properly selected are frequently more 

 effective than printed text, and their value seems to be fully apprecia- 

 ted by the newspapers and magazines and by the makers of books. 

 There is no doubt that much of the efficiency of The American 

 Museum of Natural History as an educational institution is due to 

 the photographs of the exhibits and to those made by the field ex- 

 peditions, which are used in the ways indicated above. 



The work done by the Museum photographers, Julius Kirschner 

 and Kay C. Lenskjold, is listed in the following table:
