above. Itis obvious that the long cotton

will spin finer, and Of course make more
yards Of cloth than il Jsould all have made
and would sell hIeherby the yard. From
this consideration, manufacturers can give
more {as they all say they would) for three
quarters separated than they would or could
for il altogether; and there are appropriate
uses to which the short cotton can be ap.
piled. 1 have not The shadow of doubt
that this separation will enhance the value
of cotton fifth or fourth part, as soon
as il is fairly and honestly done, and dis.
tinctly marked and tested by tie manufac.

it and the more simultaneously it is put in
the market, the sooner and the more is
advantages will be developed. have
long been aware Of these facts, and have
made many and accurate and satisfactory
experiments upon various scales, but my

been so perfectly adapted for popular use,

simplification removes every difficulty Of
completely, and also Of expense, as they

and geering, Gas the present geering will

discimilariiy and imperfection Of the pre-.
sent Gins, and that at present seem una
voitlable, but will in time be obyiated, by
The introduction Of perfect primary Gins as
they wear out or are set aside. Planters
who would wish to have both primary and
secondary, by making application in time,
can be supplied with such as if not abso.
.utely perfect, assimilate it as near as is
necessary or even desirable. Two errors
discovered in our experiments
The first, aiming at TOO much in the ma.
chinery, which made il complicated; and
next, leaving too mnch in the first quality,
which made it less perfect, for no art can
make cotton long which nature has made
short. 1t is hoped that Planters will not
let cupidity defeat itself by attempting 10
put too much in the first quality, for i, will
have to stand tire ordeal ofthe spinners, and
they cannot be deceived. Twill add 10 the
advantage ofmy plan another item speed.
1t is reasonable that the primary Gin will
pick much more in given time when il IS
confined to long cotton than when tits
kept chewing and grinding the short, and
the repicker being adapted to clean the
seed will do it quick as we'll as clean.
This makes as it were three-foid cord Of

do hope that the considerations which have
been merely mentioned in plain unvar.

advantage, the utility, or rather necessity
OF a double process, 10 do justice to cotton
