Summary — Sprayed Trees 



Summary — Unsprayed Trees 



Mr. H. a. Gossard : What was the average cost per season for spray- 

 ing a tree and what was the average return received per tree by the 

 growers? I mean the cash return at the end of the season. 



Mr. S. W. Bilsing : I havn't those figures present, but as I remember 

 it cost about ninety cents per tree, including the cost of arsenate of lead 

 and the labor and everything. The trees sprayed were about fifteen 

 or twenty feet high. I think the returns above the cost were something 

 between $4 and $5 a tree. I cannot now give the exact figures. 



President WilmOxN Newell: The next paper is by R. L. Webster.
