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. — The 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 suffi- 

 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.
