 the erection of a plant of prohibitive cost to the fruit-grower. 



The Staff of the Cooper Research Laboratory have very kindly 

 given me every assistance in their power, and have defrayed the cost 

 of spraying several large orchards during the experimental stages. 

 I have now made certain recommendations to them, and as the result

 V 2 a winter and summer sprayfluid very difficult to improve upon. 

 In carrying out this work my thanks are due to the Laboratory Staff 

 for the ready and able manner in which they have at all times 

 assisted me.
