96 NEW YORK ZOOLOGICAL SOCIETY 
CONCLUSION. 
The continuously advancing cost of practically everything 
used in the maintenance of the Zoological Park is of course a 
source of continuous anxiety. The effort to produce food in the 
Park, and to economize to the utmost limits, must be unremitting. 
At all hazards, however, we must do two things. We must keep 
our 4,000 living things clean and in good health, and we must 
prevent the buildings, dens, aviaries and fences of the Park from 
deteriorating through lack of care. If our walks are not at every 
point kept fully up to the highest standard of previous years, 
the public may know that it is because the labor and material 
has been more seriously needed elsewhere. 
During the year 1918, a very serious amount of repair work 
must be bestowed upon the eastern portion of the roof of the Lion 
House, and the ceilings underneath. 
Respectfully submitted, 
WILLIAM T. HORNADAY, 
Director.
