SIXTH ANNUAL REPORT. 79 



The placing" of additional radiators in Tortoise House. 

 Construction of plank walks leading to Primates' House. 



The work under the supervision of this department by the 

 co-operation of the Park Department for the Borough of the 

 Bronx, and paid for out of the Ground Improvement Fund fur- 

 nished by the City, will be listed elsewhere under the head of 

 "Improvements by the Park Department." (Page 8.) On

During the latter half of the year Mr. Beerbower obtained sev- 

 eral months' leave of absence without pay in order to make an 

 important railroad survey in the West. On his return he be-

 BOROUGH OF THE BRONX. 



Concerning the City's share of work in the development of 

 the Zoological Park, the year 1901 has been the most important 

 thus far. It has witnessed the completion of two contracts let
