How To Use Carbon Blsulphlds.
Carbon Bisulphide shopld be used at
The rate of to 8 pounds per 1000
cxbic feet OF space in the Eranary or
per every 100 bushels Of grain to be
fumigated- The outside temperature
should be about 10 degrees at the time
Of fumigation for best results.
II the grain 10 In q room that is
capable of being closed tightly, the
liquid may be exposed in shallow pans
above the grain. on saturated pieces
Of burlap or Il can be poured into the
pile through q piece Of pipe.
II a tight room is not available the
grain may be covered with q tarpaulin
or . piece OF canvass and the Carbon
Bisulphids exposed beneath 1t.
The greatest care should be used In
regard to IRE. Never carry lighted
lantern. Pipe or cigar into a barn
where Carbon Bisulphide Immigration
Is IN progress.
The exposure should last for So
hours. The fumlgation should DO re-
psated after an interval Of two weeks
Shovel the grain over after each
fumigation 50 a. 20 air II and prevent
the collection Of moisture and possible
subsequent heating.

Carbon Bisulphids can be purchased
from almost any drug store in small
quantities or from any chemical sup
ply house In large amounts It may
be secured from e. R. Taylor, Penn
