Grasshopper Control in the Pacific States. 9 
This amount should be sufficient to cover about 5 acres. The cost 
of these materials averages from 30 cents to 50 cents per acre. 
The following articles (fig. 7) are necessary, or at least convenient, 
for mixing the poison: 
Bucket for measuring water. 
Shovel, or hoe, to stir the bran. 
Tub in which to mix the liquids. 
Small platform or mixing box. 
Meat grinder to grind lemons. 
Small scales for weighing poison. 
The molasses, Paris green, 
ground lemons, and water should 
be mixed in the tub and stirred 
thoroughly. Then slowly pour 
this solution over the bran in the 
mixing box and stir with a shovel 
until an even mixture is secured. 
It is sometimes preferable to mix 
the bran and Paris green dry, add- 
ing the water containing the molas- 
ses and lemon. 
White arsenic may be used with 
good results as a substitute for 
Paris green, but does not mix so 
readily, and therefore requires 
much more prolonged and careful 
stirring to insure the best results. 
Alfalfa meal is a good substitute 
for bran, but does not spread as 
uniformly from a grain seeder as 
the coarse-flaked bran. Sour or- 
anges and grapefruit may be used 
in place of the lemons. 
WHEN TO POISON. 
The spreading of poisoned bran 
should begin with the abundant 
appearance of small grasshoppers 
and before actual loss to the crops

has occurred. Warm sunny days should be selected if possible, since 
the small nymphs feed very little when it is cool and cloudy. Hot 
and dry weather proves most satisfactory. The grasshopper eggs 
usually hatch later on cool, damp soils than on dry gravel ridges, and 
for this reason it is sometimes necessary*to repeat the spreading of 
poison for the complete control of this pest. If the grasshoppers
