FOREST INSECTS 
F, C. Craighead, in Charge 
Dr. Craighead and R. A. St. George spent a few days the latter 
part of March at Asheville, N. C., in conference with the Director of the 
Appalachian Forest Experiment Station and in getting the spring work in 
cooperation with the experiment station under way. Mr. St. George went 
on to New Orleans, where he will inspect, with R. M. Lindgren, of the 
Bureau of Plant Industry, a series of logs treated with various chemicals 
to prevent fungous disease and insect attack. 
William Middleton left Washingtou the latter part of the month 
in company with F. L. Mulford, of the Bureau of Plant Industry, to make 
an inspection of fourteen national cemeteries in the southeastern part of 
-the United States. The inspections will serve as a basis for recommenda— 
tions to the War Department for improving the condition of the trees in 
those cemeteries. 
A survey of the control work which was carried on during the past 
winter on the Idyllwild and Corte Madera areas, in southern California, 
was made by K. A. Salman and L. G. Baumhofer, March 5 to 11. These proj— 
ects were carried on largely on private lands, but with the cooperation 
of the Forest Service where adjoining Federal land was infested. The 
overwintering trees of the western pine beetle had been felled and the 
bark burned at the time the examination was made. The work on the Corte 
Madera tract, a small but completely isolated private area, had been very 
thoroughly carried out. 
On March 6 control work on the western pine beetle was started 
in Sequoia National Park. Two camps have now been established, and it 
is expected that work in three tributary watersheds of the Kaweah River 
will be completed by May 1. Supt. White and Mr. Coffman of the National 
Park Service were at the Berkeley laboratory on March 6 to make final 
plans with the Bureau of Entomology for the execution of this project. 
Albert Wagner was assigned by the Buresu to direct the training of the 
control crews in spotting methods and treatment of trees. 
The Yosemite National Park started its control program in the yel- 
low-pine belt on March 16. In an inspection of this area on March 14 and 
15, Dr. Salman found that an increase of the western pine beetle had de- 
veloped late in the fall of 1930 on national forest lands adjoining the 
perk boundaries. This condition threatens the Wawona Road screen, a strip 
of timber sheltering the road through the park from the adjacent cutover 
lands. Conditions were found to be similar to those on other areas of. 
the southern Sierra region where epidemics have recently developed. An 
allotment was promptly made by the Forest Service to carry on control 
work in conjunction xith that within the national park. Mr. Baumhofer 
and Dr. Salman will assist in carrying out this project.
