trees by ten or more of the owners. This, it is believed, will be 

 sufficient to control the dcpriHliitions over an area of more than 100 

 square miles in which the timber has been dying at an alarming rate 

 during the past ten or fifteen years. It will also have a marked effect 

 toward protecting the timber of the adjacent areas of the national 

 forests in which like depredations have been going on. The Depart- 

 ment of the Interior has allotted sufficient money to take the immedi- 

 ate action required to control the depredations in the southwestern 

 section of the recently established Glacier National Park. It is ex- 

 pected that the Forest Service will take the necessary action within 

 the Flathead and Blackfcet National Forests during the coming year 

 to dispose of a sufficient amount of beetle-infested tnnber, in addition 

 to that disposed of b}' private owners and the Department of the 

 Interior, to eff'ectually check the depredations throughout the entire 

 area, thus endin<T the losses of timber which have been progressing in 

 this general region during the past ten years at a death rate of at 

 least 200,000 trees annuall^y. 



IMPORTANT NEW WORK. 



During the close of the year there has been organized the most 

 extensive cooperative project for the control of barkbeetle depreda- 

 tions that has ever been undertaken in this country. It is designated 

 as the Northeastern Oregon and Western Idaho Project and involves 

 an area of over 13,000 square miles. The object is to undertake the 

 control of the barkbeetle depredations on the living timber of the 

 national forests and adjacent private and other lands through co- 

 operation between the Bureau or Entomology, the Forest Service, and 

 private owners. The plan provides that the experts of the Bureau of 

 Entomology shall make the investigations of the insects, recommend 

 methods of procedure in control work, and give special instructions 

 and advice relating to the essential details, while the Forest Service 

 and timber owners provide the funds required for the actual control 

 operations. 



The experts of the Bureau have already determined that the dep- 

 redations are so extensive within the area and the time so limited 

 before the beetles begin to emerge from the tens of thousands of in- 

 fested trees to attack the living timber, that it is not practicable to 

 undertake control work against the present (1909-10) infestation. It 

 is believed, however, that the wdiole area can be sufficiently w'orked 

 over and enough trees involved in the new (1910-11) infestation 

 located, marked, and disposed of before the 1st of July, 1911, to 

 effectually check, if not control, the depredations— thus preventing 

 the further loss of timber which has been going on during the past 

 five or six years at the estimated rate of nearly a million trees per 

 year.

The investigations of insects affecting deciduous fruits and vine- 

 yards, under the direction of Mr. A. L. Quaintance, have incliided the 

 continuation of projects under way during 1909, and beginning with 

 the spring of 1910 some additional lines of work have been taken up.
