N PRACTICALLY all cases where the fall army worm 
| commits serious injuries to cultivated crops the dam- 
age can be prevented if the farmer is on the alert to 
discover the insects when they first appear. 
Every farmer should possess a practical spraying outfit. 
He should also keep on hand at all times a few pounds of 
one of the standard insecticides, such as arsenate of lead, 
Paris green, or arsenite of zinc. 
The farmer should cultivate a spirit of suspicion with 
regard to this insect and realize that the finer the stand of 
young grain, the more tempting the bait for the army 
worm, and that a field of corn, beautiful, green, and rust- 
ling in the breeze, may at the same time have millions of 
young army worms devouring the crab grass between its 
rows, easily controlled if sprayed with arsenicals to-day, 
but which by to-morrow may have caused irreparable 
damage to his crops. In such cases a delay of twenty- 
four hours in securing advice or insecticides is usually 
fatal.
