4 Sem Process of Tanu;uo,

ScW Process OF Tanning.
d. F. Noyes, Esq. has just introduced
into his Card Factory in this city, says the
Lewiston Journal, what is called the
Eureka tanning process, or tanning in a
vacuum. The tank in which the hides are
suspended is 6 feet in diameter, and 10
feet long, which contains two hundred
and forty kip or calf hides, one hundred
andtwenty sides ofharness orsole leather
the air being exhausted the cock leading
TO the liquor is opened, when the liquor
is drawn into the hide by the exhaustion,
instantly. BY returning the liquors to
the vat again and strengthening each in
lection. the conversion into leather is
made. No hot liquors or chemicals are
used, but any kind of tanning used by
others. Some of the advantages claimed
to be derived from the use of this new
process of tanning are summed up in the
following particulars, viz =
lst. 1t is great saving of time, ma
tcrials and labor. and consequently re-
duces its cost. 1t requires but two days
for calf or kip, three to four days for up
per or harness, and eight TO ten days for
sole leather.
2nd 1t condenses the hides and causes
the ibers to be compacted, thereby So

loss.
Sd. 1t can be used in any tannery.
4th. The hide is all tanned alike, and
the flank is as perfect as any part, which

heavier.
9th. Durabiity-superior on account
not injured by chemicals or LAYING away,
rs it is taken direct from the bate and
suspended in the tank.
9Th. Saving material The tanning is
used over and over again, by returning
to the vat and strengthening each injec-
ton, consequently no chances for evapo-
ration or the handling, rs the hides are not
taken from the tank until they are finished.
Sth. Time and money-the tanner is
always ready to make any kind ofleatber.
He has only to buy the kind of hide and
consequently has not got to keep large
amounts laid away.
9Th. Money required-less capital on
account OF its quick return.
10TH Capital ofitself-capital is turned
over many more times than by the other
processes, as one has no hides laid away,
and can meet any market at any time.
The air is exhausted from the tanks by
u pump driven by water power. The sys-

uiacturers are given to its efficiency. We
say specimens of the hide which had been
in the tank two hours, which were about
one-third tanned, and in four hours two
thirds tanned; after being in the tank
day they were to ell appearances good
leather. Hides put in open watts for the
same time, hardly showed color at all. 1t
is claimed that five OF these tanks will do
the work of 1900 watts One tank, pump
and fixtures cost $1,000. One pump is
sufficient for several tanks.
Mr.. Moves uses 100 sides of leather a
week in his factory and will tan all he
uses and more-the capacity OF the tank
being more than double what he con-
sumes. About months are required to
tan leather in open vats. If the Vacuum
tanks will do the work as well or better
in two to four days, then they are entirely
blessing. 1t cost but about one quarter
the capital to start tannery by this pro-
cess that is required by the old.
This is the first Tannery of the kind in
troduced into New England, we believe,
although the proprietors have orders to
put up several at different points. They
have been used and thoroughly tested, it
is claimed, in St. Louis and other West.

worth visit by any one wishing to see
the interesting results it is claimed to ac-
complish.
