the \icinitv of Columbia I'alls, in which the utilization fur fuel, 

 etc., of about loxKXj Dout^las tir infested b\ the l)oUii;-las lir beetle 

 lesulted in the coui])lete control of depredations by this beetle, 

 which, durino- the ])receding lo to 15 years, had caused the death 

 of luore than a million trees in the iji'eneral area in\olved. This 

 was accom])lished without ultimate cost to the owner or the State. 



■"The other demonstration was in the new ( ilacier Xational 

 Park in co-operation with the Interior Department, in which the 

 I department ])aid the ex])enses of treating- the infested trees under 

 the inuuediate su])er\isiou of Mr. liruuner. The dis])osal, according- 

 to our recommeudati(ms. of 819 "white pine" trees infested with 

 the mountain ])ine beetle at a cost of about 50 cents per tree has 

 e\idently stopi)ed dei)redation by this beetle, which, during the 

 ])ast 10 to 15 years, caused the death of over 10,000 trees. 



"Two important control projects are now under way: one known 

 as the Swan Lake Project, conducted under our recommendations 

 and instructions in co-operation with the b\:)rest Service, the State 

 of Montana, and the Anaconda Copi:)er Mining company; the other. 

 Known as the Tongue River Project, located in the Tongue River 

 Indian Reservation, in which the timber is l)eing cut and barked 

 or utilized for lumber principally by Indian labor. Some $10,000 

 will be ex])en(le(l on this project to protect timber having an esti- 

 mated stumj^age \alue of over $125,000 and the value of the utilized 

 product will go far towards balancing this direct cost. There is 

 everv pros])ect that this demonstration will be a success.
