To check up the effectiveness of the poisoned bait spray, 

 all of the gooseberry drops were gathered from the ground. A 

 weekly record of the fallen infested gooseberries in the commer- 

 cial garden in 1914, is given in table 20. As the drops during 

 the first three weeks were not full grown, the actual loss is 

 greater than the number of quarts recorded in table 20. The 

 berries were ripe during the fifth week and the owner began to 

 pick his crop on July 14. 



The results of the season's spraying in the commercial 

 garden and the three neighboring dooryards compared with the 

 infestation of gooseberries on two untreated bushes used as a 

 check at a distance of about 2000 feet from the commercial 

 garden, are indicated in table 31. No record was taken of the 

 infestation of currants.
