creasing quantity of hay, straw, and feed required in the main- 
tenance of our very large collection of hoofed animals. This 
building, in addition to providing stable facilities for a number 
of horses, as well as space for carriages and vehicles in the base- 
ment, has bins and storage space on the two upper floors for a 
supply of hay and grain sufficient to last several months. 
Ice Manufacturing and Refrigeration Plant.—VYhe difficulty 
experienced during the last season in obtaining the large quantity 
of ice that is now required in the general maintenance of the 
Park, for the preservation of the large amount of meat and food 
supplies continually on hand, the care of museum specimens while 
awaiting autopsy, as well as for the needs of the Restaurant and 
Soda Water Department, brought home to us very forcibly the 
absolute necessity of our being able to take care of our own de- 
mands for ice and refrigeration without depending on conditions 
beyond our control. In 1906 we were unable to harvest a suff- 
cient crop of pond ice to fill our two small ice houses, but even had 
they been filled, their contents are now totally inadequate for our 
present needs. We urge the erection during the coming season 
of a building suitable for the storage of a liberal quantity of ice in 
one end, when a crop is obtainable, and the other end to be fitted 
with a combination refrigeration and ice-making machine of about 
ten tons capacity, thus placing us on a safe basis regardless of 
weather conditions. 
CIVIL ENGINEERING. 
George M. Beerbower, Civil Engineer. 
The volume of engineering work continues as great as ever, and 
during the year it covered many different pieces of work. Of these 
the most important were the eastern end of the Service Road, the 
yards around the Small-Deer House, the Service Road from the 
Reptile House to the Beaver Pond, the wall and yards surround- 
ing the new Barn, the West Farms Entrance plaza, and the site 
and yards of the Elephant House. Mr. Beerbower superintended 
the construction of the Feed Barn, which was designed by him, 
and furnished all surveys around the Boat House. He perfected 
the automatic turnstile invented by him last year, and it is now 
being manufactured for the Boston Road Entrance. The official 
map of the Zoological Park has been brought down to date, and 
engraved anew for the Guide Book under our engineer’s direction.
