Although numerically only 25.8 percent of the original number of lodge-. 
pole pine on the area have been killed or damaged, these constitute 65 per- 
cent of the total basal area of the stand. Further losses from the mountain 
pine beetle will probably be light, owing to the fact that the remaining 
smali trees are unfavorable hosts for the development of the bark beetles. 
Practically all. the timber of conmercial value has been destroyed, but 
enough young trees remain to assure a future stand provided fire can be 
kept out. However, the devastation caused by a mountain pine beetle epi- 
demic creates a high fire hazard, and the latter agency usually completes 
the destruction begun by the beetles. It remains to be scen if man's in- 
creasingly efficient fire protection system can preserve the remaining 
stand. 
Lectures on forest insects at E @ W cemps.--The personnel of the 
Northern Rocky Mountain Field Laboratory, at Coeur d'Alene, is cooperating 
with the Forest Service in an educational program conducted at the EC W 
camps now located throughout the Idaho and Montana forests. The program 
which this Bureau. is presenting is a lecture, Protecting our Forests from 
the Attacks of Forest Insects, illustrated with lantern slides. This 
lecture, which requires from 35 to 40 minutes, is followed by two reels 
of moving pictures entitled, Fighting Western Pine Beetles and Board Feet 
or Bored Timber. as there are twenty camps in this region, a period of 
5 weeks will be required to visit all of them. Our participation in this 
educational movement started during the week of February 12 and will be 
completed March 15. Officers of the laboratory who are taking turns in
