floor; a pool for large burrowing rodents which require 
both over- and under-ground protection from escape; 
a circular outdoor cage for skunks, and the enclosure of 
a considerable area with a high post and wire fence for 
the display of the Eastern wild turkey. The skylights 
in the Carnivora and Elephant Houses were renewed; 
a new heating system was introduced into the Elephant 
House to regulate the temperature of the water in the 
hippopotamus and tapir pools, and an intercommuni- 
cating telephone system connecting all parts of the Gar- 
den was installed in place of one of limited service, which 
had become inadequate to our present requirements. 
The outlay for animals was greater than for many 
years; this was mainly due to the purchase of a pair of 
hippopotamuses and a rhinoceros, representative species, 
the absence of which in the collection has long been a 
source of regret. 
For the second succeeding season the monkeys in the 
outdoor cage passed through the winter without illness 
or death. Encouraged by this experience, all of the 
cages in the Monkey House communicating with out- 
door summer, cages were equipped with swinging doors, 
through which their occupants had access during the 
winter to the open air, a privilege that very few failed 
to take advantage of. In addition, 'the chimpanzee, 
Johanna II, has been given a two-hour outing every 
afternoon, except on rainy days; dressed in khaki 
bloomers, she has been a feature of special interest to 
our winter visitors. On the coldest days she appeared to 
feel as little discomfort as her keeper, and contracted 
neither cold nor other illness from the exposure. 
Although the strictest economy was exercised, the cost 
of maintaining the Garden was greater than in any pre- 
vious year, practically all supplies, and particularly those 
required for the subsistence of the collections, having 
advanced in price. 
That the number of free tickets given each year to 
the Board of Education for the admission of the pupils 
of the public schools has been increased to 250,000, and
