the lint cotton in a roll are pre-.

In the saw gin.
THE ADVANTAGES OF TIE NEW
PROCESS
are SO decided and so obvious as
10 leave little doubt that Mr.. Ma.
sons cylinder gin will speedily
supplant altogether the saw gins
now used wherever cotton is cul-
tivated. These advantages are:
l. Cheapness. The cost of the
cylinder to the gin manufacturer
VIII be only q fraction-say about
one-eighth of the cost of the
saws and ribs.
2 The cylinder being made in
movable sections, only a few inch.
es wide, can, in case of injury, be
readily repaired OF replaced BY
any farmer of ordinary dexterity,
at trihing cost and without delay.
.. The points of the teeth are SO
protected or ''hoodedn that it ia
impossible for them to come in
contact with any foreign sub
stances and consequently they
run no risk of being broken OF
blunted. The reporter saw q
handful of nails thrown in the
seed cotton upon the revolving
cylinder, without affecting its
work in any way. The nails were
soon dropped out with the seed,
without injuring a single tooth.
Every Southern farmer knows
that a nail accidentally placed
with the seed cotton in a saw gin
will do more damage in half a min.
ute than can be repaired in a long
time and will often injure irrepar.
ably a brand new gin. Besides
this, the friction of the saw gin
when in contact with any foreign
substance is liable to produce
sparks Of fire and in this way often
gives rise to disastrous conhagra.
tions. Such an accident Mr.. Ma.
son claims, is absolutely impossi.
BILE with his cylinder gin.
4. The cylinder gin does more
work with less power than the
saw gin Of the same size. In a gin
containing forty saws, for instance,
only forty teeth are at work ut
the same moment. That is to say,
only those teeth which are pass
ing between the ribs at any given
time are actually utilized in gin.
ming the cotton. With Mason's
gin 1t is different. The cylinder
contains at least four teeth in the
space that, in the saw gin, is occu'
pied by the rib between the saws
so that with a cylinder occupying
the same space as forty saws, no
less than one hundred and sixty
teeth are simultaneously at work,
as against forty teeth in the saw
gin. And by the use of more than
one stripper bar in connection
with the cylinder the number Of
teeth utilized at the same moment
can be multiplied.
3. The friction caused in the
saw gin when the cotton is forced
laterally between the ribs is some
times so great as to set fire to the
cotton. The invariable effect OF
this constant friction is shown by
the chilled iron ribs themselves
which are actually worn away by
the passage of the cotton between
them. In the Mason gin the fibre
is simply pulled from the seed with
little or no friction and q vast saw.
ing of power.
8. The Mason gin does better
work than any other gin in use
In the saw gin, as already stated,
the teeth of the saws force the
cotton laterally between the ribs
Whenever two saws catch hold Of
the same fibre the fibre is inevita'
bly, cut. In fact, the cotton fibre,
If II is of good long staple, is cut
by the saws under the most favor
able circumstance In the Ma
son gin the operation Of ginning IL
precisely the came as If the cotton
was pulled from the seed by hand
and no matter how long the staple
may be it viii pass uninjured un'
der the bar as easily as the short
est staple. Mr.. Mason is conf
dent that his gin will gin sea island
cotton as perfectly and much more
rapidly aud economically than the
roller gins now used for that pur
pose. This point, however, has
not vet been practically demon
strated, in consequence Of the diff
flculty of obtaining sea island cot

Z. The absence Of friction. the
impossibility Of the teeth being
broken or blunted, and the facility
with which in case Of any accident
