late in the season, after the middle of July. See eggs on apple 
twig, Plate 3, Fig. 4. These are minute black objects. 
Remedies .—For the destruction of the eggs, proceed as for the de¬ 
struction of the eggs of the brown mite above. To destroy the lice, apply 
kerosene emulsion (14), or whale-oil soap (12), thoroughly and in a man¬ 
ner to bring the liquid in contact with the bodies of the lice. 
SCALE INSECTS. 
For the treatment of scale insects it is advisable, in each case, 
to write to the Experiment Station for specific direction. Specimens 
of the scale should also be sent. Otherwise, use the treatment rec¬ 
ommended for San Jose scale—on page 13. 
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 quite largely be kept out of the trees 
by the use of arsenic bran-mash (2) used freely about the border of 
Fig. 2.—Hopper-dozer or Hopper-pan. (After Riley.) 
the orchard, and by sticky bands (35) of Raupenleim, tree tangle¬ 
foot, printer’s ink, or even cotton batting, about the trunks of the 
trees. If the sticky bands are used they should be spread upon 
strips of cardboard which have first been wrapped about the trunks.
