The principal installations for animals are : — 
(1) The Lion House (see PI. VII). 
A very good and carefully planned two-storied building. 
The lower floor is composed of a series of large outer cages 
(the fronts of which are shown in the photograph) and a 
corresponding series of smaller inner cages. The upper 
floor is a roomy service passage, from which the communi- 
cation doors between the cages below are worked. These 
doors revolve on a vertical axis. The man above holding 
the handle has complete control over the door and can watch 
the movements of the animals through holes in the floor. 
The advantages of this system over the usual rising and 
falling door with a counterpoise balance are obvious. The 
animals are also fed from above, the keeper throwing them 
their food through a trap door, which gives the beasts good 
exercise as they spring upwards to catch the falling meat, 
and also affords a better spectacle for the visitors to watch 
than is provided in most zoological gardens, where the 
keepers thrust in the meat under the lowest bars of the 
cage front. 
This house is to be completed by building a large open- 
air enclosure behind it, communicating with the inner series 
of cages. This exercising ground will be surrounded by 
high iron railings as in the Baroda, Bombay, and Calcutta 
menageries. 
(2) The Aviary (see PI. VIII). 
A particularly well arranged building, with a service room 
in the centre surrounded by twelve cages, which are kept 
in beautiful order and are very nicely fitted up with growing 
plants, fresh branches of trees placed in barrels and pots, 
plots of grass and fountains of water. 
(3) The Waterfowl Cage. 
An extremely pretty and well planted enclosure with a 
pond. A delightful place both for birds to live in and for 
visitors to look at. 
(4) The range of paddocks for ungulates. 
(5) The Smaller Mammal House, where the wolf and 
hyaena live. 
(6) The Otter Cage, with a brick- walled tank.
