A film strip, entitled "Preventing Termite Damage, Series 260," 
is. available for distribution by the Office of Cooperative Extension 
Work, U. S. Department of Agriculture. This film strin,. with -a -/—page 
lecture, may be purchased for 35 cents. 
The field laboratory for the study of forest insects, and associ-— 
ated offices, recently at Stanford University, Palo Alto, Calif., have 
been moved and are now established in the new $500,000 building on the 
campus of the University of California, at Berkeley, which houses the 
Giannini Foundation. The new location will afford close contact with 
the California State Experiment Station, the University of California 
Forestry School,and the educational work of the National Park Service. 
The shade-tree project, under Dr. H. E. Burke, will remain at Palo Alto 
for the present. 4 
Conditions in the recreation areas in the region of Lake Tahoe 
have been the source of a great deal of correspondence- and complaints 
from summer—home owners during the past season. The most serious prob— 
lem is that due to the fir engraver beetle in white fir. During the 
season J. M. Miller has made several reconnaissance trips in- company 
with Forest Pathologist Wagener. 
An air survey of-the Eastern Plumas pine type was made by K. A.’ 
Salman and J. M. Miller on October 8. At the request’ of the Forest 
service a ground survey of this area had been made during the recent 
summer, and the survey from the air was made as a check to determine 
whether any important center of infestation has been overlooked; the 
use of the airplane was authorized by the Forest Service. 
Dr. Salman has completed a survey, following up numerous letters 
and reports of forest officers from the San Bernardino and Cleveland 
National Forests in southern California. A highly epidemic condition 
of the western pine beetle was found in Coulter pine on areas of the 
Cleveland Forest. Private owners in several of the recreational areas 
are planning to conduct control work this winter in cooperation with 
State and national forest officers. 
A study of the life history of the fir engraver beetle and other 
aspects of the problem, in white fir, was carried on during the recent 
season by George R. Struble, assisted by P. C. Johnson. The associa— 
tion of a cambium-killing fungus with the attack of this beetle was 
pretty definitely established as a result of the season's work, and a 
number of new points in the life history and habits of the beetle were 
uncovered. 
Houghton Durbrow and R. L. Furniss, who worked through the season 
as temporary field assistants on the Modoc and Lassen projects, assisted 
in the compilation of data for the reports of these projects until Novem-— 
ber 7, when their appointments were torminated. F. W. Bacon was another 
temporary assistant on the same projects.
