GRASSHOPPERS. 
Several species. Those that fly from tree to tree can probably 
be managed best by means of arsenical sprays (3 to 8), when safe to 
use them. 
Those that crawl up the trunks into the trees and jump to the 
ground when disturbed, can be quite largely kept out of the trees 
by arsenic bran-mash (2) used freely about the border of the

orchard, and by sticky bands (38) of Raupenleim or printer’s ink, or 
even cotton batting, about the trunks of the trees. If the Raupenleim 
or printer’s ink is used, it should be spread upon a strip of cardboard 
which has first been 
wrapped about the trunk. 
Grasshoppers that 
injure orchards usually 
come from adjoining al¬ 
falfa or grass fields. In 
such cases the free use of 
the hopper-pan (37) in 
the alfalfa or grass field 
is the best remedy. One
