The plots of Table 5 were treated in the same way and on the same 

 dates as those of Tables 3 and 4. The results with the first plot were like 

 those with the Early Black variety, but the fruit of the second plot showed 

 no effect from the spraying.

 with Lead Arsenate, 1920. 



Table 6 shows that two Early Black plots gave a reaction to calcium 

 arsenate like that produced by lead arsenate. These plots were sprayed 

 June 22, July 27 and August 20, the insecticide being used at the rate of 

 4 pounds to 50 gallons of water, without soap. Five or 6 bushels of fruit 

 from each of these plots and each check were stored.
