 eases) treated ivith Lead Arsenate, 1920. 



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 Earh^ 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.
