FOREST—INSECT INVESTIGATIONS 
F, C. Craighead, in Charge 
Dr. F. C. Craighead spent the first week of September at Ashe- 
ville, N. C., reviewing. the summer's work at the field laboratory at 
this point. He also spent a few days in the vicinity of the Mont Alto 
Forest School, Pa., with H. J. MacAloney, in studies of the white pine 
plantations in that region. The Mont Alto Forest School and the Pennsyl— 
vania State Forest Service gave them considerable assistance in this work. 
On September 27 H. J. MacAloney passed through Washington, D. C., 
on his return from Asheville, N. C., where he had spent 10 days in- 
vestigating injury by the white pine weevil in the Biltmore planta-— 
tions. These plantations, 30 to 35 years old, are exceedingly thrifty 
and free from damage by the weevil. They are probably the finest planta— 
tions of this type in the East. Mr. MacAloney also spent some time in 
natural pine stands in this vicinity and in plantations in natural stands 
in central Pennsylvania. These studies are made in connection with the 
completion of three year's investigation of the white pine weevil. 
Floyd F. Smith, of the Pennsylvania State Department of Agri- 
culture, spent several days in Washington in the latter part of Sep— 
tember, conferring with Mr. Middleton and other officers of the Bu= 
reau on his entomological problems. 
R. A. St. George has returned to his official headquarters at 
East Falls Church, Va. During the summer just ended the greater part 
of his time has been devoted to participation in a study of the de- 
fects of timber that appear in the course of the normal operation of 
sawmills, conducted by the Forest Products Laboratory of the Forest 
service, in cooperation with the Division of Forest Pathology of the 
Bureau of Plant Industry, in Virginia, West Virginia, and North Caro— 
lina, Much valuable information as to the character and extent of in- 
sect defects in hardwood lumber was obtained. Mr. St. George also spent 
several weeks at Asheville, N. C., in biological studies of the southern 
pine beetle. 
J. M. Miller, F. P. Keen, and H. L. Person spent a considerable 
part of the month of September on the Modoc National Forest, Calif., 
working in cooperation with Forest Service officials on a large tim- 
ber sale which has been initiated in that region. The motive of this 
Sale, involving an entire township of Government land, was based en- 
tirely on the control of Dendroctonus brevicomis Lec., which has de- 
stroyed nearly 20 per cent of timber in that region in the last 5 years.
