and the depleted ranks must be filled by new gifts and 
new purchases. Gifts of specimens, and funds for pur- 
chases, must constantly be forthcoming. 
In the acquisition of certain representative species of 
great variety but particular desirability, the Society has 
been much favored by its friends, both at home and abroad. 
Frequently it happens that the greatest zoological rarities 
are obtainable only through the good will and tireless in- 
dustry of friends who travel into the most remote and in- 
accessible regions of the earth. It is to such sources that we 
owe our musk-ox herd, walrus, mountain goat herd, spee- 
tacled bear and many other species. 
The Executive Committee makes grateful acknowledg- 
ment of the loyal and generous support it has constantly 
received from the Board of Managers, the members of 
the Zoological Society, and from the Government of the 
City of New York. Thanks to a judicious union of these 
forces, the development of the Zoological Park has gone 
forward rapidly and satisfactorily. Although the actual 
period of construction has been remarkably short for so vast 
an undertaking, everything constructed is of the most per- 
manent character. It is only just to note the fact that 
while the Zoological Park is an institution of national in- 
terest and importance, and free to all the world, with the 
exception of a few gifts of animals it has been created and 
is maintained wholly by the citizens of the City of New 
York. The State has contributed nothing.
