REPORT OP THE SECRETARY. 81 



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 xttendance was 

 barely half its present figures. 



Respectfully submitted. 



N. Hollister, Superintendent. 



Dr. Charles D. Walcott, 



Secretary Smithsonian Institution, 



Washington, D. G.
