REPORT OF THE STATE ENTOMOLOGIST KJl6 



27 



Plots 1-3 were sprayed May 31st under the supervision of Mr A. B. 

 Buchholz, nursery inspector, with Swift's arsenate of lead and a lime- 

 sulphur wash in substantially the same proportions as later. 



The second spraying was given June 21st, with Riches's and 

 Pivers's 15 per cent arsenate of lead at the rate of 12 pounds to 200 

 gallons of water, and lime-sulphur wash, 33 Baume, at the rate of 

 1 to 40 or 5 J gallons to 200 gallons of water. In this latter treat- 

 ment one man stood on the tower and one on the ground and the 

 application was extremely thorough. Plot 2 was sprayed on both 

 sides, while the trees in plot 3 had been sprayed on the west side 

 June 17th. The spraying began about 8 o'clock in the morning 

 and was finished by 9 at the beginning of a moderate rain which 

 started gently before the last trees which were sprayed could have 

 dried, and continued for a period, being rather heavy until 11.30. 

 It is probable that no very great amount of poison was washed 

 from the trees by this rain. 



The third spraying occurred August 3d, Riches's and Pivers's 

 arsenate of lead being used at the rate of 6 pounds to 100 gallons 

 of water, with a home-made lime-sulphur wash. This application 

 was confined to plot 3 and was made under the supervision 1 of 

 Mr Buchholz.
