ing the eggs in the soil, the use of fire, driving the wingless species 
and nymphs into pits, and the use of poison in one of several at- 
tractive baits. These and other methods all have their use under 
certain particular conditions, and two or more of them can frequently 
be combined in a fight against this pest. 
For general use the poisoned-bran mixture has given the most sat- 
isfactory-results in grasshopper control, and this method is especially 
emphasized in the present 
discussion of the subject. 
THE POISONED-BRAN 
MIXTURE. 
PREPARATION OF THE MIXTURE. 
The poisoned-bran mixture 
has given most satisfactory 
results in grasshopper con- 
trol. When prepared it con- 
sists of a wet bran mash 
with sufficient poison to kill 
this pest, and flavored with 
molasses and lemon to render 
it most attractive. A slight 
variation with regard to the 
proportion of water required 
in the mixture may be neces- 
sary under varying climatic 
conditions. Itshould never be 
so wet that the liquid drains 
out. The poisoned-bran mix- 
ture apparently is most at- 
tractive while moist and fra- 
grant with the odor of lemon 
and molasses, at least under 
California conditions,  al- 
though it is taken freely by 
grasshoppers after drying for 
a day or more in the hot fields. 
The following formula has proved most effective, and is recom-
