FOREST INSECT INVESTIGATIONS : 
F, C, Craighead, Senior Entomologist, in Charge 
Bastern Field Station, East Falls Church, Va. On his way across the 
State of North Carolina many dying hickory and oak trees were noted that 
appeared tc be in the same condition as the same kinds of trees in Ashe- 
ville and vicinity. This was particularly the case at High Point and 
Greensboro. At High Point two large estates were visited on which there 
were about 50 dead hickory trees and 25 dead oak trees. The hickory 
trees were heevily infested by broods of the hickory barkbeetle (Eecopto- 
gaster gquadrispinosus Say), which were mainly in'the larval stages. A 
few eggs were also found, Judging from the similarity of these conditions 
to conditions near Asheville, where a thorough study of the situation 
had been made, it woulu appear that the trees were weakened from the ef- 
fects of the drought of 1925 and in the fall of that year were attacked ‘ 
for the first time; and the insects have been breeding up in numbers since 
then. The pests have increased to such an extent that they are now a 
real menace to the community, Control measures were recommended, and 
ere being carried out as rapidly as possible, to eliminate the danger of 
further destruction, The oak trees, mainly red and black, with some 
white oaks, were found to be suffering from a combination of causes, prin- 
Cipally drought and old age, combined with a heavy attack of Agrilus all 
along the stem, A similar condition of the oeks was noted some 10 or 12 
years ago throughout the South. Many of them died following a period of 
drought; they were also infested by the same insect. At Greensboro, 
the Guilford Courthouse National Military Park, it was estimated that 
some 80 hickory trees were infested by the hickory barkbcetle, Several 
oaks were noted to be dying here also. 
On September 9 R. A. St. George left Asheville, N. C., for the 


pr. 7, B, ‘Snyder teft Washington on September 16 to investigate - 
termite damage to the woodwork of Duildings, and to aid in suggesting 
provisions for inclusion in city ouilding codes to prevent such inj 
particularly on the Pacific Coast and in the Southwestern, Gulf, and 
central Western States, where termites are eSpecially injurious. ‘The 
State Department of Agriculture of California is cooperating in this proj- 
ect. On October 18 to 21, inclusive, there will be a meeting of the 
Pacific Coast Building Officials Conference, at Phoenix, Ariz., where © 
State officials represent the territory from Seattle, Wash., to San Diego, 
Calif., and eastward to Arizona. After attending this conference Dr, 
Snyder will proceed to Honolulu, Hawaii, on a similar mission, at the in- 
vitation of the Haweiian Board of Commissioners of Agriculture and Forestry. 
Jy C,. Evenden reports the continued spread of the infestation by 
the mountain pine beetle in the Beaverhead Naticnal Forest, Undoubtedly 
the beetles dispersed from the infestation on the west side of the Conti- 
nental Divide, in the Bitterroot National Forest, thus making a flight of 
2 or 10 miles, ’
