REPORT OF THE SOCIETY 55 



ought to become more efficient. It seems possible that industrious students from 

 this College might be interested in undertaking this sort of work in the communities 

 where they live. At any rate some cooperation could no doubt be arranged by 

 which Macdonald College or the Dominion Botanist would furnish aid in starting 

 the community organization, and later provide for technical advice to the spray- 

 man so that the best results may be assured. 



In conclusion, I wish to suggest that this Society might well undertake the 

 advancement of some propaganda for more and better spraying of potatoes in 

 Quebec. At the same time in localities where conditions make it feasible, either 

 community organizations should be encouraged or some individual interested in 

 taking up potato spraying as a specialty. The plant pathologist can offer you no 

 better or less complicated means of insuring any crop against losses due to disease 

 than they have now crystalized in the accepted directions for spraying potatoes.
