FOREST-INSECT INVESTIGATIONS 
F. C. Craighead, in Charge 
At the request of the Forest Service and the Southern Pacific 
Railway, Dr. H. E. Burke made an examination in the latter part of 
September of a severe defoliation on Douglas fir caused by a species 
of Ellopia on the Cloudcroft reserve in the Sacramento Mountains in 
New Mexico. The possibility of spraying or dusting 500 acres to pro— 
tect this timber is under consideration. 
F. P. Keen has completed a regional survey of the barkbeetle 
infestation in the Klamath region of southern Oregon and on the Modoc 
National Forest, California. About October 15 he undertook the super- 
vision of the work of marking the infested timber on 15,000 acres 
within the Modoc Forest, belonging to the Forest Service and a large 
timber-holding corporation. The private operator has purchased gov— 
ernment timber, and will begin a salvage logging program on both his 
timber and that of the Government. This operation was planned not 
only to salvage very severe losses that have already been incurred, 
but also to attempt control by logging as rapidly as possible the in- 
fested and susceptible trees on a considerable area. 
H. L. Person returned October 3 to his headquarters at the Cal-— 
ifornia Forest Experiment Station, Berkeley, Calif., after spending the 
greater part of the recent season on investigations of the western 
pine beetle in the Modoc National Forest. 
J. E. Patterson recently completed the field survey of barkbee— 
tle infestations on the Crater National Park and Klamath Indian Reser-— 
vation, and on October 3 returned to his headquarters at Palo Alto, 
Calif. The Indian Service has been allotted $25,000 to combat the 
epidemic of the western pine beetle on the Klamath Reservation. An 
immense amount of yellow pine timber has been destroyed in the past 
three years. 
W. D. Bedard and W. S. Greene, temporary Field Assistants, as-— 
Signed to barkbeetle survey projects in northern California during the 
recent season, resigned September 30 to resume university work at the 
New York State College of Forestry, Syracuse, N. Y. 
L. G. Baumhofer, who has been at Halsey, Nebr., on investiga— 
tions of the pine tip moth during the summer, will be stationed at 
Coeur d'Alene, Idaho, for the coming winter. 
H. J. MacAloney is spending a few months at the New York State 
College of Forestry, at Syracuse, preparing final report and manu— 
script on his cooperative investigations of the white pine weevil for 
the last three years.
