Plot XII. 

 Plot XIII. 



Bordeaux, ^-pound copper sulfate, 6 pounds lime to .50 gallons 

 water; and lead arsenate, 2-.50. (This spray was formed by doubling 

 the amount of CuS04 in the next for comparison with it. 



Bordeaux, J-6-50 ; and lead arsenate, 2-50. (This spray was recom- 

 mended as having been in successful use for several years, in Van 

 Lindley orchards of Southern Pines, North Carolina). 



Buffer. (Sprayed like XI. 

 Check. (Unsprayed). 



See Plot II). 



The plots were adjoining and contained 20 trees each in double 

 rows, excepting II and XII, which contained 30 trees each, in three 

 rows. The data on all plots were taken from 5 or 6 central trees, 

 thus providing in all cases a "buffer" of at least three sprayed rows 

 between the sprayed data trees and unsprayed conditions. It will 

 be noted that the experiment contains six sulphur treatments, and 

 three Bordeaux.
