The first application was made June ist, using 18 pounds of 

 Dow's arsenate of lead and 7 gallons of Dow's lime-sulphur wash to 

 250 gallons of spray. The application was very thorough, 250 gallons 

 being used on 22 trees, or upwards of 10 gallons a tree. The spraying 

 began about 2 o'clock and continued until after 6 o'clock, at which 

 time the western trees in the experimental plots were all sprayed, 

 except trees D and F of plot 3 , and the western side of the eastern 

 trees was similarly treated. Owing to the lateness of the hour the 

 remainder of the trees were not sprayed till the next morning. The 

 pressure was maintained at about 200 pounds. One man stood on a 

 1 1 foot tower and the other on the ground, the latter man provided 

 with 50 feet of hose, and both equipped with 10 foot extensions. 

 About three-fourths of the blossoms were off -at the time of spraying, 

 the bloom was very uniform and rather abundant and the day bright, 

 moderately warm and with a light, shifting breeze. Mr Wellman 

 stated that the two rows in which the experimental trees were located 

 were also sprayed in the pink of the bloom for the purpose of con- 

 trolling scab and leaf roller, and that the seven trees at the south 

 end of the eastern row, namely trees B, D and F of plot 1, were not 

 treated. Considerable of this application was washed off as a result 

 of heavy rains shortly after the treatment. He also stated that the 

 two rows west of the experimental trees were sprayed with scalecide 

 after the leaves had started to some extent, in an effort to control 

 the leaf roller. These rows showed some burning of the foliage. 



The man on the tower covered the top of one tree and touched 

 up the inner side of the windward row, while the man on the ground 

 went around the tree and also touched up the inner side of the 

 windward row. The distribution of the spray was very uniform, 

 there being practically no unsprayed areas and almost no over- 

 loading of the foliage, though considerable more spray was used 

 to each tree than last year. 



The second spraying of plots 2 and 3 was given June 21, 7 gallons 

 of lime-sulphur wash "and 18 pounds of Dow's arsenate of lead to 

 250 gallons being used. The work began at 2.30 p. m., with the first 

 two trees north of plot 1, these being sprayed mostly on the north 

 side on account of the great danger of the breeze carrying the spray 

 back onto the experimental trees of plot 1. There were 250 gallons 

 used on 21 trees and the work was completed by 4.40 p. m. The 

 application was very thorough and the spray dried rapidly. There 

 was practically no burning of the foliage on the greening trees in 

 this orchard, though Baldwins standing on either side and sprayed
