hitherto suffered much for want of a proper system of 
sewerage. That which has been introduced was designed 
to meet the present and all future needs in that direction. 
The cattle-pens, buffalo, elk, and camel enclosures have 
been thoroughly underdrained, and it is believed that the 
gain from increased health in the occupants of this portion 
of the Garden, many of which have, under previously ex- 
isting conditions, suffered from the dampness of the ground, 
will in a few years fully repay the cost. 
The erection of an iron railing around both sides of the 
deer and antelope house, constituting a series of outdoor 
pens communicating with the interior, completes a long 
contemplated improvement. 
The fence on the Thirty-seventh Street line of the Garden 
has been renewed in the greater part of its extent, the new 
one being more substantial than the old one as well as sev- 
eral feet higher. 
The very extreme range of temperature during July and 
August of last summer, and that in the reverse direction 
in January and February, were not without harmful effect 
upon the collection, such extremes pressing with severity 
upon living specimens collected from varying climates, in 
all portions of the globe. The estimated loss is, however, 
not greatly in excess of the average of former years and 
that part of it which occurred during the summer was, in 
particular, below that which might have been looked for. 
Respectfully, 
ARTHUR ERWIN BROWN, 
Superintendent 
Zoological Garden, March 1st, 1893.
