The sum of $2,000 was granted for the first three of the 
above items, and work is now under way. 
A contract has been let for necessary repairs to the tile 
flooring and also for the painting of the entire interior of the 
main hall and the upper and lower offices. The present venti- 
lating ducts have also been extended and arrangements made 
for more light in the office stairway. The annual lining of the 
furnaces with brick has been done at a cost of $310, and the 
iron work in the building has been thoroughly scraped and 
painted by the Aquarium forces. 
The most important improvement during the year has been 
the installation of filters for purifying the Harbor water used 
in the floor pools for seals, porpoises and large fish. Being of 
low salinity and polluted with sewage, New York Harbor water 
is very unsatisfactory for aquarium purposes. 
MAINTENANCE. 
Park.—The sum of $200,000 provided by the City for the 
maintenance of the Zoological Park for the year 1915, proved 
sufficient and the year closed without a deficit. The sum of 
$197,074.35 has been appropriated for the year 1916. This re- 
duction of $2,925.65 is an arbitrary cut made by the City author- 
ities in the interest of general economy and will make it difficult 
for the Society to maintain the Park during the year without 
a deficit. 
Aquartum.—The sum of $47,000 provided by the City for 
the maintenance of the Aquarium for the year 1915, proved 
sufficient to close the year without a deficit. A similar amount 
has been granted for the year 1916.
