410 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1907. 
The monkey house is a large edifice covered with glass, with numer- 
ous lateral windows opening upon flower beds. This house has along 
the sides separate cages for those species that can not dwell peace- 
ably together and, in the center, a series of large cages common to 
several species. In this house are found most of the monkeys. (See 
ply.) 
The new ape house was recently constructed for the accommoda- 
tion of the anthropoids at a cost of £4,000. It contains four large 
cages wholly separated by plate glass from the wide corridor where 
the visitors are admitted. This arrangement was intended to pre- 
serve the apes from any contact with the public, to prevent their 
being stuffed with bread or other food, and also to preserve a uni- 
form temperature in the cages. I consider it, however, an inferior 
style of installation and think that it might be well to replace it, 
and this opinion is shared by the present secretary of the council. 
At the time of my visit this house contained six young chimpanzees 
and three orang-outangs. There were also in outside cages where 
the apes remain until evening, a young chimpanzee and three gib- 
bons. (See pl. 1.) The lemurs are installed fo: the most part in 
a house which they share with the edentates. They thrive there 
very well and not infrequently breed; I even noted two hybrids 
from a crossing between Lemur xanthomystax and L. ruffifrons. 
The carnivore occupy eleven separate structures. The principal 
one is the lion house, constructed in 1876 at a cost of £11,000. The 
body of this house is of red brick, 70 meters long and 21 meters wide; 
it has a wide corridor upon which wide windows open on the south 
side, while on the north side are fourteen large cages, each of which 
has two interior compartments, the latter being large dark dens 
which ought to be removed so as to give free access to the exterior 
cages. Behind these dens there is first a long service gallery, then 
four great grilled cages projecting without the building in which 
the animals may enjoy the outside air. * * * (See pl. 1.) 
The pinnipeds are represented in the garden by sea lions and seals, 
which live together in a very fine large inclosure constructed in 1905 
(the sea-lions pond). This inclosure is occupied almost entirely by 
a large pond 1.80 meters in depth near the shelf from which the ani- 
mals dive, and surrounded by shores either grassy or rocky. In the 
middle of the pond are three little islets and at its western end a large 
structure of rockwork in which are sleeping caverns for the animals. 
With these animals, giving a little animation to the scene, are a 
dozen penguins, which have bred here during the present year. * * * 
“J learn recently from the secretary to the council that there are now being 
installed above the service gallery a certain number of bridges by which the 
animals may have free access to the exterior cages.
