officials, and the private owners, and control work was begun about 

 the middle of February, 1912, under the advice and instructions of 

 a representative of this bureau. The sum of $6,350 was allotted by 

 the three interests involved, and about 30,000 trees have been marked 

 for felling. 



Other work has been done by this station at various points in 

 the territory included in its operations. 



Station No. 5 is located at Yreka, Cal., and its work covers an 

 area including California, Arizona, New Mexico, and a small sec- 

 tion of western Nevada. Two important projects are under way. 

 One is located on Moffit Creek, on private lands, wher6 the owners 

 have paid the expense of operations under the direct supervision of 

 a representative of the bureau. The other project, designated as 

 the Craggy Mountain project, covered both National Forest and 

 private lands to an extent of 15,000 acres. Here 927 large trees were 

 treated at a cost of about $3,000, the cost being met by the Forest 

 Service. Prior to this time a reconnaisance made by forest officials 

 indicated that during a period of 30 years previously the accumula- 

 tion of insect-killed timber had amounted to from one-fourth to one- 

 half of the total stand, and it was found that the same condition 

 is common in the forests of California and Oregon. It is prophesied 

 that the work carried on under this project will be an effective 

 demonstration to individual owners and to States that this injurious 

 work of the beetles can be stopped at a minimum of expense. 



Station No. 6 is located at Klamath Falls, Oreg., and covers 

 Oregon, Utah, the greater parts of Nevada and Washington, the south 

 half of Idaho, and a small section of western Wyoming. The main 

 demonstration project undertaken by this station was on 8,800 acres, 

 the property of several private owners, in the vicinity of Parkers Sta- 

 tion, Oreg., where there was a heavy infestation by the western pine 

 beetle and a lesser one by the mountain pine beetle which indicated 

 widespread depredations in the immediate future. The trees requir- 

 ing treatment were very large, the sugar pine averaging 33 inches 

 diameter breast high and the yellow pine 22^ inches diameter breast 

 high. In all 300 trees, containing a total of 538,000 board feet, were 

 treated at an expense of less than $2 a tree. The low cost of this 

 demonstration should serve as an object lesson and will doubtless do 

 much to bring about that spirit of cooperation among timber owners 

 which the bureau is trying to arouse. 



Work on the Whitman National Forest, coming under the Avork 

 of this station, was terminated June 30, 1911, but the months of July, 

 August, and September were devoted to a complete study of the area 

 worked over, as well as to adjoining untreated areas, to secure data on 

 which to base conclusions as to the results of this work. 



Station No. 7 has been located at Spartanburg, S. C, and its work 

 covers an area including North Carolina, South Carolina, Georgia. 

 Florida, Alabama, Mississippi, Louisiana, and Texas. Since great 

 damage was threatened by the southern pine beetle in these States, 

 as referred to in the last annual report, the necessity for concerted 

 action by owners of pine in these States during the fall and winter 

 of 1911-12 was perfectly obvious. This station was started in con- 

 sequence, nnd every effort was made to stir up an interest in the 

 subject among the owners of the trees. The southern press assisted 

 actively; addresses were made by experts throughout the infested
