considerable burning on the east side of that tree substantiated his 

 statement and illustrated in a striking manner the connection between 

 excessive precipitation and the danger of burning. Tree 3 of plot 1 

 was sprayed by mistake on the west side June 2 2d. Neither of 

 these applications appear to have had any material influence upon 

 the yield as will be seen by referring to the tabulated data below. 



The third spraying was given August 3d, 3 pounds of arsenate 

 of lead paste to 50 gallons of water and lime-sulphur diluted at the 

 rate of 1 to 45 being used. Between 190 and 200 gallons of mixture 

 were applied at a pressure of 175 pounds. The work was done under 

 the supervision of Mr L. A. Toan.

The trees in plot 1 show a great variation in yield, this ranging 

 from 268 to 1694 apples and there is nearly as wide a variation in 

 the amount of perfect fruit, the percentage of scabby apples run- 

 ning high and in no case falling below 82.58. The total wormy 

 apples vary from 13.58 to 22.24 P er cent, the smallest being on the 

 most fruitful tree and the largest on the one producing the next 

 heaviest yield. The proportion of " shallow " affected apples runs 

 from approximately one-third to one-half of the total wormy, being 

 somewhat lower than in other orchards.
