The totals of the table show that most of the softening of the berries was caused by the first 

 five fungi, and that the first two were the most active.

 Tables 2, 3 and 4 show the results of spraying Early Black vmes with 

 "Corona" lead arsenate used at the rate of 4 pounds to 50 gallons of 

 water, without soap. The plots of Tables 2 and 3 were the same areas, 

 respectively, so numbered in 1918. ^ In 1919, plots A. L. 3 and A. L. 4 

 were treated on June 24 and July 11 ; A. L. 5 on June 23, July 12 and 31 ; 

 and A. L. 7 on June 24, July 11 and 24. All the plots of Tables 3 and 4 

 were sprayed on June 23, July 26 and August 20. The quantity of fruit 

 stored in 1919 varied from 1 to 4 bushels for each plot or check. In 1920, 

 6 or 7 bushels were stored for each area of Table 3, and from 2 to 7 bushels 

 for each area of Table 4. The effect of this spraying, shown by the per- 

 centages in the tables, except possibly those of plot B, confirms the re.sults 

 of like tests in previous years. ^
