rig But any rig that will throw
fine mist spray will do.
A too heavy application of poison
will burn the foliage. Rank growing
foliage will burn more easily than
more mature, or more slowly growing
foliage. If the spray is applied in
the evening, say from 600 p. M. to
1900 p NJ, it will have less ten
dency to burn the foliage II the foli-
age is badly burned, the grasshoppers
will not eat the burned leaves. So
use as strong a spray as possible
without burning the leaves badly. Clio
yer heads in bloom and pollinating at
the time of spray will blast more or
less, and will not fill well. Alfalfa
will burn more easily than clover. The
finer the spray mist, the less likely it
is to burn the foliage. Good results
cannot be obtained without a fine
spray. If possible, at first, spray only
a short distance in the field and wait
until the next day to see if the foil
age is being burned. Do not spray in
windy weather Amount of spray de-
! livered can be governed somewhat by
the speed of the team Rain will wash
off the spray and render it more or
less ineffective. Heavy, dense foliage
will give poor results, because spray
cannot fall on lower leaves, and hop
pers can eat imprisoned leaves If
possible spray before blossoms APP
pear and when foliage is about . to
10 inches high. If done in this way,
results should show rs to 80 per cent
dead grasshoppers. Results will be-
gin to show in about days, and in
one week 60 to 20 per cent of the hop
pers should be dead. They will con-
tinue to die for weeks The live
hoppers will eat the dead ones, thus
| helping the work along. Do not let
chickens eat many of the poisoned
hoppers.
One OF the men running a spray rig
here has arranged the pipe containing
the nozzles so that he can tilt the
nozzles up or down from the horizon
tai. By fitting the nozzle down,
spraying can be done in weather too
windy for horizontal nozzles, but the
mist will not be spread so evenly
For the beginner it is advisable to
fill the spray tank with water, or
partly fill it with known quantity of
water, and spray the water over a
known area, so as to find the rate at
which the spray is being delivered.
working properly, before trying to
spray with poison. When ready for
poison, fill spray tank half full of
water. add poison and molasses, and
fill on up with water. Ditch water
will do if it is clear so as not to clog
MOBILES. The sodium arsenite is solu-
able, and the agitator in the spray
tank will attend to the mixing.
At present we are conducting ex-
periments to learn if we can get good
results without using molasses in the
spray. We have made a number OF
tests so far with good results, and
would like very much if each person
spraying would spray a small area
without the molasses and then make a
careful examination as to comparative
results. Leaving out the molasses will
cut down the cost of materials one
