CONTROL IN CULTIVATED FIELDS. 
Corn, grain, and bean fields frequently suffer severe injuries from 
grasshopper attacks. Such infestations usually come from unculti- 
vated, waste areas and alfalfa fields, to which the grasshoppers fre- 
quently return for the night. The poisoned bran mixture should be 
spread over such adjoining waste areas, as well as on the fields where _ 
the crops are injured. On the cultivated fields it is well to spread the 
poison during the morning hours, when the grasshoppers are com- 
ing in.
