NEEDS OF THE ZOO 



Keplacement of antiquated structures that have long since ceased 

 to be suitable for the purposes for which they are used is still the 

 principle need of the Zoo. The more urgently needed buildings are : 



(1) A new administration building to replace the 146-year-old historic 

 landmark which is now in use as an office building for the Zoo but 

 which is neither suitably located nor well adapted for the purpose; 



(2) a new building to house antelopes and other medium-sized hoofed 

 animals that require a heated building; and (3) a fireproof service 

 building for receiving shipments of animals, quarantining animals, 

 caring for animals in ill health or those that cannot be placed on 

 exliibition. 



Respectfully submitted. 



W. M. Mann, Director. 

 Dr. A. Wetmore, 



Secretary^ Smithsonian Institution.
