COTTON-SEED OIL
To be Extracted by Means Of an Ordi-
nary Crusher and Benzine at
a Saving of
Nearly One Hundred Per Cent.-A Plan
that VIII Enable Every Planter
to Make His Own Oil.

The Planters Journal, for September, Just
TO hand, contains a letter from Mr.. W. r.
JehDson, in which he gives the following
very important statement from Prof. Hill
yard, Of the University of Mississippi:
Using the Plantation Cotton-Seed Oil
thirty to thirty-ive gallons of oil may be
obtained, and the hUlls and cake returned.
This requires well skilled labor, the loss of
the oil is in the hulls and cake. For q days
work, with a 5000 pound mill, the account
would stand: Forty-five gallons of csude oil
for the cost of extraction. While this would
be much better than the present method OF
selling seed at $40 per ton, as the bulls and
cake, containing potash and phosphorus
acid, could be returned to the ground, but
these hulls and cake contain twenty-five gal
Ions OF oil, valuable ss an article of money as
oil, but useless as fertilizer.
l suggest a simpler plan by which ION OF
cotton-seed will give all its oil, of sixty gall
Ions, for market, and allow the fertilizing
ingredients of potash and phosphoric acid
to be returned to the soil, to make the land
richer for other crops OF cotton.
In ton of good seed there are sixty gall
Ions OF oil, distributed as follows: Obtained
from the kernel by mill, thirty-five gallons;
remaining In the cake, twenty per cent. of its
weight in oil, say nineteen gallons; in the
hulls, six gallons. place thirty-fve gallons,
what have understood the strongest presses
can extract; if less, larger percentage re-
mains in the cake. Ali the oil (six gallons)
in the hulls by presses is lost; that of the
cake is sold, at present date, for S27 so per
ton.
ell can be obtained. and ali The asoii f. r.
dients" of potash and phosphoric aeid re-
turned TO the soil, it certainly preseuts
subject OF much interest to the psanters
mine with little instruction or trouble. Let
the party wishing 10 examine the matter
take any given weight of good seed, having
the weight exact, and then record, to pre-
vent mistake, crush the seed, say through a
coffee mill, if small quantity, break the
bottom out Of bottle, place the seed In the
bottle, a cork ia Its mouth, the bottle ln-
verted, pour benzine on the seed until it
covers them; next morning remove The
cork and allow the fluid to drip,
then add again bepzine as long IS
the fluid comes away colored. Now sep
arate the benzine from the dissolved oil and
weigh the resultant oil; it will be found to
be in ratio sixty gallons to a ton of seed;
also, if the seed from the bottle be perfectly
dried and weighed, the loss of weight will
chow the quantity of oil extracted, and will
be in ratio OF sixty gallons to ton of seed.
The apparatus required would not be e1-
pensive, nor require extraordinary ability to
operate. A crusher to break the seed, tanks
to leach them, and a still to recover the ben
zine, would complete the requirements. The
whole cost of expenses to extract the oil
would not exceed the value of the oil now
thrown away in the hulls, six gallons 20 each
ton, and also pay for the loss of benzine in
the manipulation.
/ may conclude by saying that the process
would be similar to what has long been in
vogue in Europe, 10 extract fats from old
bones before making them into bone-black,
they using bi-sul phuret of carbon. As ben
zine is cheaper than bi.sulphuret carbon, 1
would use it, though the carbon sulphuret
would also extract all the oil from kernels
and hulls
