152 THE MONTANA EXPERIMENT STATION 



of apples in fruit growers associations, Montana's reputation for 

 clean apples will be irrevocably lost. It is physically impossible for 

 the Board of Horticulture to spray all of the infested orchards at 

 the proper time, and the work cannot be left to them with any hope 

 cf success. The apple growers themselves should not only take an 

 interest in this matter, but should actually do the work of spraying 

 for themselves. It should be sufficient for this Board to instruct 

 in spraying and indicate where spraying is necessary. The indi- 

 vidual owners should own spraying outfits and spray their trees as 

 directed.
