J. C. Evenden spent the greater part of September in a survey 
of the Bighole Basin, in the State of Montana, checking up results of 
the $100,000 control project conducted by the Forest Service, and in 
mapping the new infestation by the bark beetle in this area preparatory to 
outlining plans for next year's work. The entire staff of the Coeur 
d'Alene, Idaho, field laboratory assisted in this undertaking. 
Through cooperation between this Division and the Forest Products 
_ Laboratory, four sets of timbers have been impregnated with 14 chem-— 
ical wood preservatives; the sets will be sent to South Africa, Aus-— 
tralia, Hawaii, and Panama, respectively, to be tested as to preserv— 
atives in preventing attack by termites. Competent entomologists at 
these locations will report on the results of the tests. 
The entire Division of Forest Insects moved its quarters in the 
latter part of September, occupying the rooms on the north side of the 
Insectary Building.
