that they will find the poison. On the cultivated soils the grasshoppers 
frequently descend in the evening and spend the night under the 
warm clods. Best results are then secured by spreading the poison in 
the morning, since the grasshoppers again make their appearance 
with the first rays of the morning sun and will take the poison bran 
before entering the trees. The poison mixture never should be placed 
in small piles against the trees, since burning of the bark may result. 
Covering small trees with cheesecloth or burlap frequently is prac- 
tised, but is useful only for temporary protection (fig. 11). Grass- 
hoppers eat through the lighter material and girdle the tree where the 
cloth is tied, unless it is extended to the ground.

CONTROL IN MOUNTAIN MEADOWS. 
Mountain meadows frequently become infested from the grassy 
slopes of surrounding hills and from low ridges, where the grass- 
hoppers collect in the fall to deposit their eggs. The small grass- 
hoppers appear in early summer and destroy the valuable meadow 
grasses. The poisoned bran mixture has given splendid results in 
destroying grasshoppers under these conditions, and in some sec- 
tions has saved stockmen thousands of dollars’ worth of fodder. The 
poisoning should begin when the nymphs appear in considerabie 
numbers, and should be continued until late in the fall, even after 
the crops have been removed from the fields, if necessary. This later 
poisoning is to prevent the laying of eggs in the soil.
