INJURIOUS INSECTS OF I90Q AND IQIO. 21 
eggs hatch in the spring, in normal years between May rst and May 
15th, or thereabouts. These pockets are turned over by the plow, 
preventing the escape of most of the newly-hatched hoppers. Con- 
sequently late fall or early spring plowing (five or six inches deep) 
is one of our best remedies against these insects. Evidently, there 
must be co-operation on the part of all farmers in a neighborhood, 
in this important matter. Where deep plowing is impossible, a 
faithful harrowing would help shallow plowing, thus more effec- 
tively breaking up the egg-masses and exposing the eggs to the 
varying changes of the weather. The plowing of roadsides in the 
late fall or early spring, where there is serious infestation, is de- 
sirable. 
(2) PLow1nc UNDER YounG Hoppers: Young hoppers just 
hatching can sometimes be taken care of by plowing them under, 
beginning on the outside of the field in which they are hatching, 
and plowing toward the center. This turns many under, and by 
depriving them of almost all food, makes it much more difficult for 
them to reach the edge of the plowed piece where they might dam- 
age a valuable crop. 
(3) CrippLtE Mixture: When grasshoppers are young, or 
half grown, a poisonous bait, known as the Criddle Mixture, has 
proved effective in many parts of the country. This consists of one 
part Paris green and about 100 parts of fresh horse-manure, by 
measure. Enough water is added to make the mass soft without 
being sloppy. It can be taken to the field on a wagon or stone- 
boat, and scattered about by means of a paddle. One might think 
that turkeys and other fowls, in picking over such material for bits 
of undigested grain, might be poisoned. This, in our own expe- 
rience, does not seem to be the case. It would probably be dan- 
gerous if used in proximity to small chickens. 
(4) Burninc Younc Hoppers: It is sometimes possible to 
burn over a tract swarming with young hoppers, and thereby save 
an adjoining crop. This burning, however, must be done with care, 
and the farmer must decide whether he is doing more harm to his 
hay crop than he is getting benefit thereby. 
(5) Potsonep Bran: Garden truck to which chickens do not 
have access may be protected to some extent by mixing bran with 
water to the consistency of chicken feed, adding Paris green until 
the mixture has a greenish color (2 parts Paris green to 25 parts 
bran, by measure), sweetening with cheap syrup or molasses, and
