this reason, and to meet the present

REMEDIAL AND PREVENTIVE MEASURES.
With millions of bugs in his field or
swarming from out of an adjoining field,
either of his own or his neighbors, what
is farmer to do ? Usually It js not until
the former condition prevails that the
| farmer becomes aware that there is
chinch bug within miles of his field, and
after having learned of their immediate
presence, he almost invariably waits to
see what they are going to do, and by
the time he finds out, they have become
diffused over 80 large an area as to make
an effort to control them q stupendous
affair. If then, the bugs we're gathered
on the outer row of corn, es in all cases
which we observed in Ohio last year,
they left the wheat fields for the corn as
soon ss the grain was harvested, follow
the directions given in circular letter,
June "a, 1895, by Prof. s. A. Forbes,
State Entomologist Of Illinois. which is
as follows
"Dissolve one. half pound OF hard or
soft soap in one gallon of water, and heat
to the boiling point. Remove from stove
and add two gallons of coal oil, churnine
the mixture with good force pump for
fifteen minutes. When the emulsion is
formed it will look like buttermilk."
To Or III quart of this emulsion add
fifteen quarts of water, and apply to the
corn in spray-preferably before 10 q.
m. or after 3 p. m. The bugs should be
washed of 90 that they will float in the
emulsion at the base of the plant. A
teacupfull is generally sufficient, but the
quantity must vary with the number Of
bugs infesting the corn"
That the above is effective and of prac.
tical value, we know from personal ex.
perience, and l saw many fields last
summer in Central Ohio, that could have
been thus protected, if the effort had
been made to do 80 and at the proper
time.
If the bugs have taken possession of
more than one of the outer rows of corn,
along the edge where the bugs were
smooth and roll or pack the surface of
the ground with a clod crusher. Bury
a chinch bug under three or four inches
of soil and it will not crawl out, as have
learned by actual experiment in the field.
This applies to corn there is no way of
treating the pest in the wheat fields or
| meadows. l once tried to use the emul.
sion among wheat, drenching the small
patches of whitened straw when these
first began to show in the field, but could
not see that any good resulted from the
application.
So far as remedies are concerned, then,
we can only recommend the use of ker.
osene emulsion, and in more serious
cases the blowing of the infested area
followed by narrowing and rolling.
In case migration is in progress from
q wheat field to corn field, If about
three deep burrows are plowed as closely
side by side as possible, the invasion
may be stopped. A few bugs will get in
and climb out of the first furrow, but
while the third will succeed in stopping
that they seem to be escaping after a
few days, fill up the trenches with q
plank, clod crusher or scraper, level off
and roll, making new burrows where the
ridges were between the old burrows,
and you have new series of obstruc.
tions.
A combination of the trench and
emulsion assures has been tried this
year with perfect success. A deep fur.
row was plowed and cleared out, and
when it became we'll filed bugs, and as
soon as they began to cross it, it was
thoroughly drenched with the kerosene
emulsion and all that had fallen into it
were quickly killed.
If the outer rows of corn are grown up
with Foxtail or Panic grass, the bugs
will largely remain on that in preference
to going farther, or if q strip OF millet be
sowp along the margin between the two
fields, 80 as to have 1t up several inches
by the last of June, or about harvest,
this will cause halt in the migrating
hordes, and keep them engaged in feed.
ing on the growing millet until the food
supply begins to fail. when they will
move onward. If about about this time
the farmer will put in his Plow and turn
under bugs, grass and all and harrow
and roll the ground, he will leave so few
bugs above ground that they will cause
little if any injury. This has been tried
where the strip OF millet was displaced
by foxtail and panic grass, and know
that it will work effectually.
Where neither of the foregoing meas
ures are practicable, and prompt defense
is necessary, barrier of tarred boards
may be used, and mixture of 8 parts
coaltar and one part linseed oil, thor.
oughly mixed and spread upon boards,
either laid fat on the ground, or placed
on edge and the upper edge daubed with
the mixture. Where the line of fdefense
is not too long, and one has the boards
at hand, this may serve to hold the bugs
in check for q time, but If one is obliged
to purchase the lumber, the expense
will be a serious objection. In some
cases ridge has been thrown up and
made smooth and compact on top, the
tar mixture being applied in train with
q watering pot without the sprinkling
attachment. The trouble here is that
the wind blows the dust over this train
of oil and tar. soon crusting the surface
90 that the bugs crawl over it without
sticking fast. If taken in time the ap.
