These dermnstl’aUons were continued during the Summer of 1907) with the result that a. oery superior qUaLly )i iiuu .a as produced upon i/h,e trees winch v ere sprayed. llecords made at the end of live season from the entire crops of thirty seven sprayed trees and thirtyjvini> nnsprayed ones in different orchards, including observations on more than 1 10, 000 fruits, showed 22 per cent, of wormy apples on the sprayed trees and 4b . per cent, on theunspraycd ones. Of the sprayed fruit six per cent, and of the uusprayed fruit 38 pi r cent were scabby. During the fall the foliage of the sprayed trees was much healthier than that of the unsprayod ones. In many cases from fifty to seventy-live per cent, of the foliage of uusprayed trees was on the .ground early in October, and in some instances the trees were almost completely defoliated at that time. At the same time the leaves of the sprayed trees were brtgfto green ■and comparatively free from fungus diseases.

The crop was’gathered from two hun'clreld ana 1 live sprayed trees and sevbnty-on|o unsprayod trees. The av>er ago j ickl of the Sprayed trees was 8.4 bushels per tree and of the unspraye trees iii.h bushels per tree.
