duced unsanitary conditions. Early in the year, therefore, a new 

 connection was made with the main on E. 182nd St., and a new 

 3" main was brought to the building. At the same time the entire 

 steel piping, which had become so badly corroded as to leave in- 

 sufficient room for the passage of water, was replaced by pipes of 

 a larger diameter and better material, in addition to which a new 

 emergency storage tank, for breakdown service, was placed in 

 the attic. 



Burrowmg Rodents. 

 A new design was made for the Burrowing Rodents cages 

 and some of the material made ready for erection in 1922. 



Outside Lion Cages. 

 The repairs and renewal of the outside Lion House Cages 

 were continued throughout the open winter, and those cages

 the fronts of the cagework generally had a complete overhauling. 



Outside Bird Cages. 

 The outside cages of the Large Bird House on the east side 

 were given similar treatment by renewing the floors, overhaul-

Wild Fowl Pond. 

 The Wild Fowl Pond, into which the drainage of the Small 

 Deer yard and the corrals to the south formerly ran, was made 

 more sanitary by intercepting this drainage by means of a 6" 

 pipe and a proper sump, and by carrying it through the entire 

 length of the pond and making connection with the sewer at the 

 north end. 



Pygmy Hippo Tank. 

 In the Elephant House an excellent permanent concrete tank 

 was built for the Pygmy Hippos, giving these valuable and rare 

 animals a properly heated and cleanable loathing pool. 



Storage Shed. 

 The most notable addition furnished by this fund was a 

 steel storage building for vehicles and machinery 40' x 50' in 

 size. This is a sul^stantial structure with 5 doors and sufficient
