APPENDIX 7 
REPORT ON THE NATIONAL ZOOLOGICAL PARK 
Str: I have the honor to submit the following report on the opera- 
tions of the National Zoological Park for the fiscal year ended June 
30, 1949. 
The improved economic conditions were reflected in satisfactory 
developments at the Zoo during the year. The animal collection was 
gradually improved by obtaining rare or otherwise desirable animals 
to fill available cages, and personnel recruitment and training pro- 
gressed satisfactorily, although it was not possible to fill all vacancies. 
With increased man power and more materials available, progress 
was made in taking care of the most needed repairs, and minor im- 
provements were completed. 
As of June 30, 1949, there were 3,724 specimens in the collection, an 
increase of 927 over the previous year. These represented 755 species, 
an increase of 65. Not only was the collection increased in size, but 
the quality was improved by the addition of animals that are not well 
known, thereby adding to its educational value. 
The National Zoological Park renders a variety of services to the 
American public. Besides the animal exhibits and the providing of an 
attractive recreation area, valuable opportunities are offered for 
students of biology, particularly vertebrate zoology, as well as for 
artists, photographers, writers, and research workers—utilizing 
methods of research that do not endanger the welfare of the animals 
or of the public. Other direct services are answering in person, by 
phone, mail, and telegraph, questions regarding animals, their care 
and transportation; the furnishing of information to other zoos and 
private and public agencies regarding structures for keeping and 
housing animals; and cooperation with other agencies of the Federal, 
State, and municipal governments in research work. 
THE EXHIBITS 
Animals for the collection are acquired by gift, deposit, purchase, 
exchange, births and hatchings, and are removed by return of speci- 
mens on deposit, exchange, or death. Although depositors are at 
liberty to remove the specimens that they place in the Zoo, many 
leave the specimens for the rest of their lives.
