jurious than in wet weather. Unless regular spraying is prac- 
ticed the application of poison for bugs is likely to be neg- 
lected. Flea beetles flourish best in dry weather. It is an 
established fact that thorough spraying at the proper time 
will materially lessen the damage done by flea beetlés. If flea 
beetles are not, at least partially, checked by spraying it is 
positive proof that the work has not been done properly. With 
us, the opinion is steadily growing that very few farmers spray 
thoroughly enough to secure the maximum profit from the 
operation. There seems to be little danger of overdoing the 
matter. The experience of T. E. Martin, West Rush, N. Y., 
is strong evidence on this point. Mr. Martin sprays with ex- 
treme thoroughness and imvariably secures large increase in 
yield and large net profit.
