REPORT ON THE NATIONAL ZOOLOGICAL PARK. 81 



buildings, could be much better shown and more pleasantly and 

 healthfully located in outdoor quarters with warm but unheated 

 shelters. A large African lion, kept in the park for two winters 

 without artificial heat, has shown marked improvement from such 

 treatment. Such provision should be made for the exhibition of 

 certain of the lions, the Siberian tigers, and other mammals. Out- 

 door cages, adjoining the winter quarters, should be constructed on 

 the east side of the lion house for the leopards, jaguars, and hyenas. 

 The unsightly row of cages along the crest of the hill north of the 

 bird house should be replaced by new sanitary yards with comfort- 

 able but unheated retiring quarters attached. 



Owing to the great increase in the number of people who take 

 advantage of the recreational and educational features of the park, 

 the necessity for a substantial increase in the appropriation for 

 regular maintenance expenses is apparent. For the safety and com- 

 fort of the public the number of policemen, attendants, keepers, and 

 caretakers must be augmented, as the force now maintained is not 

 greater than was considered necessary when the attendance was 

 barely half its present figures. 



Eespectfully submitted.
