lime sulphur and three-fourths of a pint of nicotine, while the eastern 
row was sprayed with nicotine while the buds were in the pink. 
The second application was made July roth to plots 2 and 3, 
the ‘“‘ spray gun ”’ being used as before. The preceding night it had 
been raining and the trees did not dry off until 1.30 in the afternoon, 
at which time spraying began. The apparatus carried easily to 
the top of the trees though it overdrenched the foliage when the 
limbs were within a foot or two of the nozzle. The best work was 
secured at a distance of 6 to 10 feet from the trees and better results 
could doubtless have been secured if the applications from the 
platform had been supplemented by a man working from the ground. 
The foliage showed injury from spray, evidently due to an excessive 
amount and in August the ground was partly covered with fallen 
leaves. There were used in the second spray 16 pounds of arsenate 
of lead to 200 gallons and 5 gallons of lime sulphur wash. Approxi- 
mately 12 gallons of material were applied to each tree. The 
work was completed about 3 o’clock in the afternoon with the 
probability of showers occurring within two hours. 
The setting of fruit was so light on plot 3 in particular that it 
was not considered worth while to give the third spraying early in 
August. Consequently the following data relates only to the 
efficacy of one and two applications for the control of codling moth. 
The fruit was picked September 27th and classified by the Ento- 
mologist and Mr L. J. Steele of the local farm bureau.
