a sump containing an automatic pump. This cellar is now dry 
for the first time since this building was erected. 
Lion House Boiler. 
A new boiler was installed in the Lion House and connected 
with the heating system. This boiler is of sufficient capacity to 
carry the building during any but the coldest weather, and has 
resulted not only in greater convenience, but also in coal saving. 
Repairs to Heating Systems. 
Necessary work was done, also, on the heating systems of 
the Ostrich House, Elephant House, Large Bird-House, Hospital 
and the winter house of the Eagle and Vulture Aviary. 
Repairs to Upper Bear Dens. 
The floors of these dens had been built in such a slipshod 
manner that they had settled in many places, making it im- 
possible to keep the dens clean and in a sanitary condition. It was 
necessary to break them up and regrade and concrete them in a 
permanent manner. 
Parrot Cages. 
Sixteen large and twelve smaller parrot cages were planned, 
constructed and set up in the Large Bird-House, this work being 
finished just in time to receive the large collection of these birds 
received from Australia. 
Eagle and Vulture Aviary. 
At the outdoor Eagles’ cages, a beginning was made to 
thoroughly repair and paint these cages to prevent their collaps- 
ing. The supports of these cages consist of semi-circular steel 
frames, clamped together to hold the wire, and as it was im- 
possible to reach any portion of the inside surfaces and paint 
them, corrosion had taken place to a very large extent. As far as 
we have been able to proceed this year, this structure was taken 
down entirely, thoroughly cleaned, painted, filled with an elastic 
cement which will prevent further ingress of water, and then 
re-erected. On account of the difficulty of obtaining bolts and 
other materials, it was possible to finish only three divisions.
