Of one pound 10 4uu busneis from
twenty-four to thirty-six hours, II
will kill the weevil without ipjur-
ing the seed. Many farmers have
only a small amount Of seed corn,
end this can be successfully fumi-
gated by placing it in an old coal
oil barrel or any gas.tight recepta-
Gle. Where such a barrel is used
il can be frightened at the top by
with burlap over which
boards are weighted down. For
such fumigation three ounces OF
carbon bisulphide is sufficient.
Such a barrel can be placed out in
an open space without danger to
any one. The dangerous quality
Of this gas has been questioned. 1t
is believed that some people have
confused it with hydrocyanic acid
gas. The latter is used for fumi-
CATION purposes and where the in
sects are unquestionably difficult
TO kill. II is made by combining
potassium cyanide, sulphuric acid
and water in their proper proper
tons, the resulting gas being ex-
tremely poisonous. In the case OF
high life, however, there is less
danger. A person affected by the
gas is not in immediate danger OF
his life, and for such as have large
buildings to fumigate, the follwing
symptoms by which an overdose
may be known are given: The
first effects of the gas on person
are indicated by severe headache,
followed by dizziness and dryness
of skin. When these symptoms
are present a person should leave
the building and go into the fresh
air until these feelings have passed
oil. otherwise should he be over
come in the building and not dis.
covered in time, the result would
be fatal. In the case of hydrocy-
anic acid gas, however, were a
peason TO be attacked with the
above described feelings, the re-
suit in every case would be fatal.
Carbon bisulphide is clear col
orless liquid, very volatile, and
when the glass is sufficiently dense
is innammable and highly explo-
sive. 1t has a very offensive odor
by which it's presence may be east
ly recognized. Where the fumiga-
ton is such that person may be
exposed to this gas for considera'
BILE time and feels the effects of be-
ing everdo.ed, he should go into
the open air, stoop down and thor
oughly aerate his lungs.
Carbon bisulphide is approx
two and one-hslf times the
weight of air and can be poured
almost directly from the vessel to
the ground. II should therefore
be placed only on top Of the corn
so that il shall sink and in this
penetrate every crevice of
tie corn crib.
A very important precaution to
be preserved is to keep away from
fires of any kind, whether it be
lighted cigars, pipes, matches, Ian
terms, glowing embers, etc.
II carbon bisulphide is suspected
Of being adulterated, expose a
small quantity of the chemical in
a shallow dish. 1t should evapor-
ate rapidly and completely, leav-
ing no sediment of any kind in the
vessel
Don't say that carbon bisulphide
will not kill the corn weevil. The
most competent entomologist in
the United States advocates its use
and the experiments at the depart
ment Of entomology at the A. and
NJ. College are absolutely convinc-
ing. Don't put oil the fumigation.
Do it now. A. +. CoNRADr,
