ments on two stations that direct their appeal to people interested 

 in cultural and educational activities — the noncommercial television 

 station WTTW (Channel 11) and FM radio station WFMT, which 

 also published in its monthly Fine Arts Guide extensive series of 

 photographs of Museum exhibits. 



The Chicago and North Western Railway, Chicago Transit Au- 

 thority, and Illinois Central System continued to display without 

 charge in their local stations placards advertising lectures and other 

 Museum events. Museum notices appeared in Headline Events in 

 Chicago (published monthly by the Chicago Association of Commerce 

 and Industry), Chicago Exhibitions Calendar (published quarterly by 

 the Adult Education Council), and This Week in Chicago (distrib- 

 uted by hotels and organizations concerned with tourists). 



MOTION PICTURES 



The twice-a-year general inspection of all film material in the Film 

 Library, which includes cleaning and repairing, was completed for 

 the year and all film subjects were catalogued and accessioned. The 

 Film Library now numbers 101 complete productions, besides thou- 

 sands of feet of color and black-and-white film in the stock-footage 

 library on various subjects of natural history. During the year 

 many films were examined for material that could be incorporated 

 into films now in use, and all storage files were relabeled. Both new 

 and replacement titles were photographed, and damaged sections of 

 films were printed and replaced. 



Toward the close of the year all photography for the Museum's 

 new film production was completed. Laboratory work, editing, and 

 preparation of script are now in progress and the film will be ready 

 for public showing during the coming year. This film will supplant 

 the present film on the Museum's various activities, "Through These 

 Doors," which was in continuous use throughout the year on a free- 

 loan basis as an educational service of the Museum to all requesting 

 organizations, schools, and colleges. It has been impossible to keep 

 accurate count of individual viewers, but it is conservative to say 

 that "Through These Doors" has been seen by many thousands in 

 the ten years that it has been in use. 



Requests are received from time to time for the loan of films 

 taken in various parts of the world during Museum expeditions. 

 This material, which shows habitats, people, and animal life, has 

 rare and unusual value because our film record is, in many instances, 

 the only one in existance.
