58 PROTECTION OF PLANTS, 1918-19 



firm this statement I will mention a result which has been obtained in the vicinity 

 of Quebec. It is a question of neighbouring fields sprayed in various ways by 

 their owners. The results are very different as you will see. 



Return in Gross 



Number of Bushels Bushels Yield for money from receipts 



Sprays sown harvested one 1 bushel $1.00 per 



(Valued at $1) bushel 



None 15 50 3.3 $3.33 $50 



1 spray 15 100 6.6 6.50 100 



2 sprays 12 150 12.50 12.50 150 



3 sprays 6 100 16.60 16.50 100 



Needless to say that neighbours who have not sprayed, and who are now con- 

 vinced by this example, will not fail to do so this year. Moreover the requests 

 made to the Horticultural Societies for sprayers are three times more numerous 

 than they were before : another proof of the work done in the mind of the farmers 

 since 1917. 



From the last statistics, the yield in potatoes amounts to 147 bushels to the 

 acre, compared with 80 bushels last year. This is an increase of 67 bushels. Part 

 of this surplus is certainly due to spraying; but let us be fair, the weather and 

 and other agents have favourably influenced the growth, if we were to share it 

 too, each side would have 33§ bushels. Now, 33| bushels multiplied by 264,870 

 acres under cultivation gives the fair surplus of 8,873,145 bushels, due to the 

 treatment of seed grains and to poison Bordeaux mixture sprays. In figuring 

 the potatoes at $1.00 per bushel, we would have a profit of $8,873,145.00, which 

 we think is quite an appreciable result showing better than anything else the 

 efficiency of the methods of control. 



You no doubt remember that last year, on the occasion of our Spring Meeting, 

 I had the pleasure to communicate to those present the plan of a proposed ento- 

 mological or "plant protection" campaign, which I intended to carry out during 

 the summer. I must state that none of the articles in this programme have been 

 neglected and that our efforts have not proved useless. 



In conclusion I might say that our work, although often disappointing, 

 sometimes affords satisfaction. For ten years now, your Society has scattered 

 the good seed all around ; we have endeavoured to reach the same end during the 

 past few years. Results have not always been apparent, except in orchards, but 

 at this date, we can look behind us without fear of being deceived, but with satis- 

 faction. This does not mean to convey that the campaign has come to an. end; 

 no, but it is now in the right way and can be followed up quickly. With your 

 assistance, we expect to be able to record a big advance in 1919.
