#. C. Craighead, Entomologist, in Charge 
In the first week of March Drs. Blackman and Graham visited 
Washington to discuss plans for continuing nrojects in the Lake States 
and the Kaibab National Forest during the coming year. Cooperative 
arrangements with the Forest Service on the studies of the tip moth at 
Halsey, Nebr., were completed. 
J. C. Evenden, of the Coeur d'Alene, Idaho, field station, visited 
the forest insect station at Palo Alto, Calif., in March. Plans were 
completed for cooperation with the National Park Service on insect-control 
projects. The summer schedule and assignments on certain research projects 
of the Division were also considered. 
Re. A. St. George recently spent ten days in the field examining 
experimental plots on the lands of the Great Southern Lumber Company at 
Bogalusa, La. 
On March 11 and 12 Dr. 7. B. Snyder took vart in an inspection of a 
section of a test-pole line of the American Telephone and Telegraph Company 
between Quantico and Fredericksburg, Va. Squared, pine poles, after having 
been impregnated for their entire length with coal-tar crecsote, by cyLinder 
pressure process, were set, mostly in 1897, This is one of the oldest lines 
of creosoted poles in the United States. The very few failures due to 
insects or fungi were to be accounted for by. season-checking which extended 
into the wood more deeply than did the preservative treatment. This pole 
line is still in excellent condition.

contain as little as 43 per cent of oi]. The manufacturers have accepte 
65 per cent by volume as the minimun’oil content of this emulsion, and are 
making special effort to conform to that standard. If the standard is 
maintained the dilution heretofore recummended Tor use will have the strength 
desired for geale control.
