BARRlERS.-The latter part OF
June or early in July the chinch bugs
are obliged 20 search for new sup.
ply of food, and as most OF them are
yet without wings, they migrate OF
foot, 80 that barriers placed around
the infested fields help greatly. There
are two good types OF barrIers--the
dust and the oil or tar barriers. The
aim is to destroy as many of the bugs
Of the first brood as possible and to
prevent their getting into other crops
to rear the second broods. which lives
through the winter.
Dust Bnrriers.--The dust barriers
are very effective and easily main.
tanned so long as rain does not inter
fere. The plan is to keep supply OF
fine, dry, hot dust over which the
bugs attempt to crawl during the hot
part of the day. The heat destroys
many. and the fine dust closes the
breathing pores and smothers those
not overcome by the heat
\ dust barrier can be made BY
blowing a strip 10 or 10 feet wide and
thoroughly working It until fine dust
mulch is fo.-Aed. It is best to ploH
before the ground gets too dry and
hard and then be ready to work I
when the bugs begin to migrate. Dm

from about 10 o'clock until 4 in III,
afternoon, when the bugs are musI
active.
Oil or Tar Barriers Dust barriers
are all that we need during dry
weather, but in case of rain We must
establish an oil or tar barrier. A
thick, viscid road oil similar to No.
OF the Standard Oil company gives
even better results than the tar. Be.
fore applying the oil, low, well.
packed ridge should be formed. Then
by using an ordinary sprlnkling can

still, by attaching a hose to a barrel
Of oil, one can run narrow line OF
oil along the ridge. This line must
be kept fresh by adding more oil from
time to time. AT first Il may be nee.
essary to add the oil twice a day. but
later only once in two or three days
The line of oil should not be more
than an inch wide.
Post noles every rod or so on the
side Of the line next to the infested
field will help to trap the swarms of
migrating bugs, where they can be
killed by means of little coal oil a

maintained throughout the migrating
period for less than So.
Winter Burning.
II farmers will cooperate in fight
ing the bugs with the barriers during
the summer. few will succeed IN
reaching corn or other cropc. and
those can be killed by sprinklng with
strong soap suds or tobacco tea. or
by burning with Il flame. But where
careful summer work Is not done
swarms of bugs will be collected dur.
ing the fall in meadows and PASTURE.
in bunch grass and other grasses and
hedges, under leaves and other pro.

All such harborlng places should be
burned over in the early winter. when
/ IL is dry and the wind is not too
strong. This does away with the
swarms which fly to wheat in the
spring
