54 NEW YORK ZOOLOGICAL SOCIETY 
PUBLICATION FUND. 
The balance on hand on January 1, 1921, was $1,896.02. 
The enormous cost of printing has checked the publication of 
the Society during the year, but a new Aquarium Guide Book 
was made available. It was prepared by the Director of the 
Aquarium after years of study, and contains 170 pages of text 
and 160 pages of illustrations. 
The regular publications of the Society, while somewhat de- 
layed, appeared during the year as follows: 
The Twenty-fourth Annual Report of the Society for the 
year 1919. 
The six Bulletins for the months of January, March, May, 
July, September and November. One of these Bulletins was 
the White Rhinoceros number, containing an article by Herbert 
Lang, Assistant Curator of Mammalogy, American Museum of 
Natural History, which virtually forms a popular monograph 
on the White Rhinoceros and is of great Zoological value. 
Of Zoologica Vol. II, Nos. 10 and 11 were published. 
LIBRARY FUND. 
While the Library Fund is able to purchase from time to 
time the new zoological publications that are most important to 
the practical work of the Zoological Park, it is highly desirable 
that as soon as funds become available, extensive purchases of 
books may be made to bring the Library up to a standard that 
will be in keeping with the general work of the Society. 
A special appeal has been made to the members of the 
Society for books or for money to purchase books for this pur- 
pose. The Fund requires at least $5,000 in order that the 
Society’s Library may be brought up to date. 
IMPROVEMENT AND REPAIRS. 
The difficulty of obtaining labor and the necessity for econ- 
omizing during the war led to the accumulation of many needed 
repairs both to buildings and to walks and roads.
