54 Report of the President 



groups from various clubs and other organizations. On 

 several occasions, such as the visit of several hundred 

 crippled children on June 7, other members of the Scientific 

 Staff have kindly helped us in conducting parties through the 

 exhibition halls. 



Early in 1921, the photograph albums for the use of the 

 public were moved to new cases in the negative 



otograp ic room ^ thus centralizing the work of the photo- 

 graphic department and supplying a photograph 

 room similar to the slide room. 



The largest piece of work accomplished during the year 

 and one of the most important was the grouping, captioning 

 and cataloguing of more than 2,300 negatives made by Dr. 

 Frank M. Chapman on his expeditions to Mexico, the West 

 Indies, South America, Canada, and western and southern 

 United States. 



For exhibition at the Second International Congress of 

 Eugenics held at the Museum in September, 219 prints and 

 143 enlargements were prepared, and 101 negatives and 

 prints were made of the exhibition itself. 



During the year the photographic department has made 

 4,694 lantern slides for use in schools and colleges in all parts 

 of the world. 



The School Nature League, under the leadership of Mrs. 

 John I. Northrop, we believe is doing a most important work 

 in connection with its various Nature Rooms, 

 Contact with an( j d m ' m g the year the Museum has cooperated 

 . . with this organization in every way possible, 



especially by furnishing the auditorium for large 

 public meetings and by the lending of natural history specimens. 



During the past few years considerable work has been done 

 with the Boy Scouts and similar organizations, especially 

 through the efforts of Mr. B. T. B. Hyde, who has given un- 

 sparingly of his time to this work, both in the Museum and 

 in the field. Docent service has been supplied to visiting 

 troops and occasional talks to Scouts and Scout Masters have 

 been given in the small lecture halls. 



Last spring in order to increase our usefulness to these 

 organizations, a course of five lectures to Boy Scouts, at the 

 suggestion of Mr. Hyde, was given in the large auditorium.
