FOREST-INSECT INVESTIGATIONS 
F. C. Craighead, in Charge 
Dr. F. C. Craighead attended the Fourth International Entomological 
Congress, held at Ithaca, N. Y., from August 12 to 16. He presented a 
Paper on "The organization and activities of the division of forest in- 
Sects," and also a summary of J. M. Miller's paper on "Barkbeetle epidemics 
in relation to windfalls." 
William Middleton also attended the Congress from August 14 to 
18, and presented a paper entitled "Factors influencing the activity of 
Shade-—tree insects and the utilization of these in control work." 
Dr. T. E. Snyder likewise attended the Congress from August 12 
to 18. He presented a paper entitled "Termites modify building codes," 
at the sessions of the section of forest entomology. A fairly large 
representation of the workers on termites of the world were in attendance 
at these meetings. 
Dr. S. A. Graham, of the University of Michigan, an agent of this 
office, also attended the Congress, and presented a paper on "The larch 
sawfly in forestry." 
Another attendant at these meetings was H. J. MacAloney, of the 
field laboratory at Amherst, Mass. 
The special sessions on forest insects were very well attended. 
sixty-five American and European forest entomologists and foresters were 
there, and many exceptionally interesting papers were presented, two of 
them by members of the United States Forest Service. E. N. Munns, in 
Gharge of the Forest Service Experiment Stations, read a paper on "Sil- 
yicultural practices in the control of forest insects," and Philip Wake- 
ley, of the Southern Forest Experiment Station at New Orleans, La., 
presented a paper on the pine tip moth, Rhyacionia frustrana Comst.

At the close of the last special session on forest entomology a 
vote of thanks was extended to Professor Glenn Herrick for the splendid 
program he had prepared and for the assistance and the many courtesies 
that he had rendered those attending. A motion was carried requesting 
that the special session on forest entomology be made a permanent part 
of the Congress.
