brevicomis in yellow pine trees slashed on the right of way of the highway 
and of a study of resulting conditions in the standing timber adjacent to and 
within 3 miles of the slash. A slashed strip 1 chain wide and 40 miles long 
is involved in this study, This strip passes through a primitive stand of 
pine timber typical in every way of the forested areas of the southern Oregon- 
northern California region, so that the results of this study should be 
applicable to the region in general, 

During the past month, Dr. H. E. Burke has continued his investigation 
of the Monterey pine sawfly. While the investigation was in progress the 
insects emerged ‘and deposited eggs which are now hatching. An unsuccessful 
attempt was made to fumigate the earth where these insects were overwintering 
in the larval stage, using paradichlorobenzene. It is possible that during 
the winter the temperatures were too low to volatilize the fumigant. 
R. A. St. George has just left for an extended trip through the South. He 
will visit several large lumber companies which are conducting cooperative 
experiments on the prevention of insect injury to crude forest products. One 
or two large-scale tests of chemicals for the prevention of insect attack will 
be tried out. 
About 500 white, red, and yellow pine and Douglas fir seedlings have 
recently been planted at the Eastern Field Station, East Falls Church, Va. 
These seedlings were received through the courtesy of the forest Service and 
are to be used for experimental purposes, particularly for the feeding of 
defoliating insects.
