TWENTY-FIFTH ANNUAL REPORT 51 
for exhibition as soon as wall space in the galleries of the Ad- 
ministration Building is made available by the removal of the 
Heads and Horns collection to the proposed new Museum. 
It is the purpose of your Committee to ultimately have a 
complete Gallery of all the large North American animals in 
their native surroundings. More than half of the species already 
are represented by paintings. 
In the meantime the smaller mammals and birds will be 
painted in the order of their increasing scarcity, and the animals 
most threatened by extermination will receive immediate atten- 
tion. In the case of the fur-bearing animals, this is a matter 
of pressing importance. 
To complete the collection at least $10,000 will be needed, 
and subscriptions for this purpose will be welcome. 
A collection of early American hunting prints, inclusive of 
hunting and bird shooting, is being assembled by the Art Com- 
mittee, and Dr. George Bird Grinnell of the Board of Managers 
has succeeded in gathering many interesting early prints that 
will be placed on exhibition as soon as space is available. 
During the year important moving photographic records of 
animals at the Zoological Park have been made by Raymond L. 
Ditmars, Curator of Reptiles. 
These pictures were shown to the Managers and members 
at the various meetings of the Society. Through the use of some 
of them in the theaters throughout the country the interest in 
the Zoological Park has been greatly fostered. In this way we 
have secured our only permanent records of certain rare animals, 
which lived only a short time at the Park, such as the koala, an 
extraordinary arboreal marsupial, which died a few days after 
its arrival from Australia. 
The Executive Committee intend to encourage the develop- 
ment of its photographic department as soon as funds are avail- 
able for such purposes. 
TROPICAL RESEARCH STATION. 
The Tropical Research Station was reopened in April, 1920, 
under the charge of its Director, Mr. William Beebe. The re- 
ports received from time to time from Mr. Beebe indicate a very
