On receiving the report of the programme committee, a paper was 

 presented, entitled: 



THE USE OF ARSENATE OF LEAD FOR CONTROLLING THE 

 CODLING MOTH. 



By A. F. Burgess, Columbus, Ohio. 



Early in the spring of 1903 a series of experiments was planned to 

 test the effect of spraying for controlling the codling moth. This 

 insect had proved very destructive in an orchard at Delaware, Ohio, 

 and although some spraying has been attempted in previous years the 

 applications were not made in a systematic manner and the insect had 

 not been held in check. It had continued to increase in abundance, 

 and the loss resulting thereby had become so serious that systematic 

 treatment was rendered absolutely necessary if a profitable crop of 

 fruit was to be raised.
