FOREST-INSECT INVESTIGATIONS 
F. C. Craighead, in Charge 
Dr. T. E. Snyder sailed from New York February 5 for a trip to Panama, 
where he will go over his experiments with tropical termites. Dr. Snyder 
is running a large and important series of tests of various treatments 
designed to protect woods in the tropics from infestation by termites. The 
tests are being conducted on Barro Colorado Island, Canal Zone. 
William Middleton attended the National Shade Tree Conference held 
at the Brooklyn Botanical Gardens, Brooklyn, N. Y., February 7 and 8, This 
was the fifth of such conferences, and the second following permanent or- 
ganization. It was very well attended by scientists and commercial shade— 
tree men. A. F. Burgess, formerly of the bureau, and now with the Plant 
Quarantine and Control Administration, was elected vice-president for the 
year. Many interesting papers were presented, covering the subjects of case 
records, callus healing, aeration of tree roots, tree injection, oil~spray 
problems, fertilization of trees, and a series of papers on both insect 
pests of trees and fungus growths of trees. H. J. MacAloney prepared a 
paper on the white pine weevil as a pest of shade trees for presentation at 
the conference. 
C. W. Collins, of the Gipsy-Moth Laboratory, was in Washington Feb— 
ruary 18 to 21 to confer with Dr. Craighead, and with Doctors Marlatt and 
Quaintance and Mr. Graf, regarding the work of the Laboratory. After leav— 
ing Washington he made a short visit to the Japanese Beetle Laboratory. 
P. D. Sanders, of the Department of Entomology of the University of 
Maryland, visited the Gipsy—Moth Laboratory on February 6. 

INSECT PEST SURVEY 
J. A. Hyslop, in Charge 
In February J. A. Hyslop visited the colleges of agriculture of Min-— 
nesota, Illinois, Indiana, and Ohio, to study methods of making the insect— 
pest survey now in vogue at these stations, and in particular the long-— 
established Natural History Survey of Illinois. 
State insect pest surveys will be organized this year in Minnesota 
and Ohio, and it is hoped that other States will soon establish similar 
work.
