J. C. Evenden, Forest Insect Field Station, Coeur d'Alene, Idaho, 
attended the annual meeting of the Western Forestry and Conservation 
Association, held at Vancouver, B. C., on December 3, 4, and 5, 1921, 
where he ares Seed &@ paper relative to the forest insect situation in 
the western United States. The paper was supplemented with an exhibit of 
photographic enlargements. 
At the request of several lomber companies and turpentine operators 
an investigation was made by R. A. St. George, November 22 to December 20, 
to determine the cause of the death of some 70,000,000 feet of pine*timber 
extending over a territory from Alabama to Texas. Most of the dead and dying 
timber is located in western Texas, centered about Angelina County, but a 
considerable portion is in Louisiana. It was found that the various species 
of pine trees (longleaf, shortleaf, loblolly and slash pine) were dying from 
the combined effects of such agencies as drought, fire and turpentining. | 
Bark beetles, usually of secondary importance (Ips avulsus, I. calligraphus, 
and I, grandicollis), attacked the trees while their tops were still green. 

“A little later the trees turned brown and died. A preliminary study indicated 
that probably little summer wood had been added this year and that the 
drought was the primary cause of the death of the trees. Most of the trees 
appear to have died within the last three months.

STORED PRODUCT INSECT INVESTIGATIONS 
EK. A. Back, Entomologist, in Charge 
Dr. EH. A. Back visited the Thomasville, Ga., and Orlando, Fla., 
laboratories in October. 
In the latter part of November Dr. Back was present by invitation at 
_ the fumigation of five million cubic feet of space in one of Buffalo's 
largest establishments. 
On December 2 E. A. Vaughan visited Port Saint Joe, Fla., to 
investigate a most interesting outbreak of Dermestes vulpinus in an 
establishment producing fish oil and fish scrap. 
Dr. E.. A. Back gave a talk on insects which attack household goods 
in storage before the Household Division of the American Warehousemen's 
' Association, at Hotel Drake, Chicago, December 10. 
J.-C. Hamlin and Curtis Benton, of the Dried Fruit Insect Investi- 
gations, at Fresno, Calif., have had an opportunity during the past month 
to secure valuable data on the effectiveness of HCN fumigation of sacked 
prunes. Five thousand tons of sacked prunes were fumigated in a modern 
warehouse. 
Mrs. Sibyl S. McDonald has resumed her duties as artist, after a 
period of absence.
