The (luestion is often asked: "\\ Ould the San Jose sc.ile become 

 3. serious i)est in the latitude and under the climatic conditions 

 of Montana"? While tliere is room f(M- a reasonable doubt that 

 tliis scale would l)e a serious menace to Montana fruit trees, the 

 fruit growers sliould keep the benefit of the doid)t on their side and 

 xwge the enforcement of the laws that are intended to prevent its 

 admittance and sliould watch for, and if possible, suppress it as it 

 comes. 



It is true that in localities where it thrives methods are now de- 

 vised wherel)}- it ma}' be held in control but the application of these 

 means is expensive and the presence of the pest is a cause of anxiety 

 to the owner of the infested premises.
