Very little has been done in the way of permanent im- 
provement during the past year. An iron squirrel cage 
has been erected to take the place of the former wooden 
structure. The skating house has been torn down, and the 
site covered by vulcanite paving. An addition has been 
made to the green house, by using the material from the 
skating house, the labor being done by the regular employes 
of the Garden. 
As heretofore, rigid economy has prevailed, and the ex- 
penditures for maintenance show a material reduction. 
The heating apparatus in the various buildings has been 
thoroughly overhauled, and new boilers put in where the 
old ones had been worn out by long service. A number of 
trees and shrubs have been planted, and the surface of the 
lawns improved and placed in good condition. 
The usual list of animals is submitted herewith. 
Respectfully, 
ARTHUR ERWIN BROWN, 
General Superintendent. 
Zoological Garden, March 1st, 1884.
