CARBON BiS(IPilIDE As IVNi.
GATOR.


Clemson College, Nov. 10.-Farmcrs
in south Carolina will be intcrcstcu Il
at this time in learning how 10 trca,
thcir corn cribs 10 protect their grain
from insect and rodent rayagcs
during The winter y. T.. Cunra,ji
entOmolOgist OF Clemson College
has the following information to
give on this subject.
Carbon bisulphidc is now quite
commonly used for fumigating corn
in the crib to kill the granary in
sccts rs well as rats and mice. Tn,
material should be purchased in guam
titles of not less than forty pounds
in drum and at this rate it will
cost 10 cents pound f. o. b. at orig
inal shipping point. Thc metal drum
IS charged for extra, but this charge
Will be refunded when t'c drum is
returned.
Carbon bisulphide should be kept
screwed tight in the head of the
drum. The liquid is very volatile
and converts into gas rapidly when
exposed to air. The LIQUID as well
us the gas is highly inilammablc
and when set on fire may explode
violently. This, however. should
not cause any undue fear because it
is merely Necessary 80 >"cr fire away
from it just as one would IN hand
ling gasoline OF 4un powder. Its
presence is always quickly detected
by its ''rotten egg odor.
The first step when intending IT,
fumiSatc is to have tight crib
This may be accomplished i'm several
ways. A permanent arrangement
would be to have the crib sealed
carefully on the inside. Many farm
the crib on the inside by papcrinG
it. The fumigating dose is pounds
to 1000 cubic feet of space Begin
ming at the back of the crib, sprinkle
the liquid as uniformly as possible
over the surface Of the corn or other
grain to be fumigatcd. The gas
given off. being heavier than air,
sinks Immediately through the corn
and in this manner pcnctratcs TO the
wecyils.
Carbon hisulphidc is not dangerous
to apply when care is taken to
breathe as little of it as is practica =
bic. Conlinc the gas in the crib Us
long as possible. III the average
crib it will dissipatc itsu.i ~ thc
course OF "a to As hours, hu' H. Is
much better to have Il ti"nf cri.
where q heavy charge of g. C2u b,
confined for from n to 48 hourG.
1t must be borne in mind that ;hC
dose that has been recommended is
for n thoroughly tiGht crib. In one
in which the walls arc composed Of
only single layer of sheathing, the
dose should be doubled for / 200
cubic feet Of space. The fumisa-
ton will not in any way injurc tho
terminating powers nor the fccdin"
qualities of the corn. In most cribs
one fumigation in fall. Immediately
after the corn is stored, is sufficient
but when one finds in spring that
the insects are becoming very active
the dose may bc repeated.
For fumigating, select Il warn
day. with temperature not below
G5 or 20, and start about 10 a. NJ.
In using carbon bisulphidc do no
forget to keep away fire OF all kinds
including flame, cmbcrs, lanterns
lighted pipe OF cigar; and during the
first "a hours after fumiSation d,
not enter the crib with any Kind o
fire. BE sure before lumiSating Il
have your crib as ti&ht rs YOU cai
