THE GRASSHOPPER PROBLEM AND ALFALFA CULTURE. 7 
PREVENTIVE AND REMEDIAL MEASURES. 
Preventive measures, as here restricted, apply to a period antedat- 
ing the hatching of the young; while remedial measures are such as 
deal with the insects after hatching and with methods of destroying 
them. 
While many modes of procedure have been advocated, tending 
to ward off impending attacks, and perhaps even a greater number 
of devices constructed and mixtures compounded for the destruction 
of grasshoppers, we will here consider only such as are readily and 
cheaply obtainable by the farmer and ranchman and those most 
practical.in application.

DESTROYING THE EGGS. 
Destroying the eggs of the grasshoppers seems to be the only 
preventive measure that promises to be worth while attempting, 
except, perhaps, the destruction of the young as they are hatching. 
Destruction of the eggs may be accomplished by either plowing, 
harrowing, disking, or cultivating, in the fall or winter, all roadsides, 
ditch banks, margins of cultivated fields, uncultivated fields, and 
grassy margins along fences. In short, all waste lands that it is pos- 
sible to reach in this manner should receive attention, unless it is 
known that no eggs were deposited there. 
The soil need not be stirred deeply, 2 inches being a sufficient 
depth to accomplish the desired effect; and circumstances will 
probably dictate the kind of tool or tools that a farmer ought to
