FINANCES 



The appropriation for the National Zoological Park is carried in 

 the District of Columbia Appropriation Act. In the fiscal year 1957, 

 $720,000 was appropriated, of which $545,627 was alloted for sala- 

 ries, leaving $174,373 for the operation of the Zoo. Included in this 

 last figure is $65,000 for animal food, $29,000 for maintenance and re- 

 pair, and $15,000 for the purchase of animals. In addition to animals 

 purchased from appropriated funds, many valuable animals are 

 acquired through judicious exchange. 



The estimated net worth of the Zoo is approximately $4,500,000, 

 which includes the value of the land, buildings, improvements, ani- 

 mals, and the current appropriation.
