SECRETARY’S REPORT 195 
heavy mature forest on Barro Colorado itself. Research in this 
mainland area will be completely undisturbed, as the whole Pipeline 
Reservation is closed to the general public. 
The policy of helping promising graduate students in biology has 
continued. Charles F. Bennett, Jr., of the University of California in 
Los Angeles, completed the main part of his study of temperature 
and humidity gradients in the forest on Barro Colorado; but additional 
climatological data are still being collected and will be included in 
Mr. Bennett’s published report. Robert H. Barth, of Harvard Univer- 
sity, completed a preliminary analysis of the behavior of birds of the 
family Formicariidae in mixed flocks in the forest. 
The analysis of the behavior of sphingid and saturniid moths con- 
tinued by Dr. A. D. Blest of University College, London, which was 
supported by a grant from the National Science Foundation to the 
resident naturalist, was completed. Dr. Blest’s results will be pub- 
lished shortly. A second research project supported by a grant from 
the National Science Foundation to the resident naturalist, a compara- 
tive study of the evolution and behavior of certain tropical birds, is 
stillin progress. A new research project on the evolution and behavior 
of American monkeys was started this year. 
Plans have already been made to move the office on the mainland into 
larger quarters in the former Ancon Post Office Building, as soon as 
these became available after remodeling. 
FINANCES 
Trust funds for maintenance of the island and its living facilities 
are obtained by collections from visitors and scientists, table subscrip- 
tions, and donations. 
The following institutions continued their support to the laboratory 
through the payment of table subscriptions: Eastman Kodak Co., New 
York Zoological Society, and Smithsonian Institution. Donations 
are also gratefully acknowledged from the following: Eugene Eisen- 
mann, C. M. Goethe, and Frank Hartman. 
PLANS AND REQUIREMENTS 
The improvement of the library will continue. It will be necessary 
to obtain new books and journals as they are published and to com- 
plete present journal files. 
It is hoped to continue the program of employing temporary bio- 
logical aides. Arrangements have been made to employ John H. 
Kaufmann, of the University of California, to continue his research 
on the behavior and ecology of the coati and other carnivores on 
Barro Colorado Island and to begin a census of the vertebrate species 
in the mainland area.
