plete control immediately surrounding the house. It must be 
taken into consideration that it would require an enormous num¬ 
ber of hens and considerable attention to affect control over any 
great area of land. 
ARTIFICIAL CONTROL 
In the artificial control of grasshoppers, we may consider the 
two main heads: Prevention and Remedies. 
Under the first, attention must be given to prevent hatching 
and lessen egg deposition. The latter may be brot about by clean 
cultivation along ditch banks and fence rows. This will expose 
the hoppers to natural enemies and weather conditions, which will 
reduce their numbers and cause the remainder to oviposit in areas 
likely to be cultivated, and so result in a subsequent destruction 
of the eggs. 
Exposure of the eggs to air, sunshine, natural enemies and 
weather conditions is very effective in hopper control. This may 
be accomplished by plowing, discing or harrowing. The opera¬ 
tion should be performed before the eggs hatch. It is therefore 
an excellent plan, in late fall or early spring, to plow all ditch 
banks, fence rows, and road-sides where grasshopper eggs are 
known to be deposited. Plowing should be at least eight inches 
deep. This will bury the eggs sufficiently to prohibit most of the 
young hoppers from making an exit thru the soil surface upon 
hatching. In alfalfa fields and other places that cannot be plowed,
