Where and How Bank Note Paper
Is Made.

4 correspondent of the Boston Tran
script, who has visited the factory, near
Philadelphia, in which the government,
bank note paper is made, describe IS the pro.
cess as follows;
NY frat visit was to the boiler room,
whore, in large rotary boiler the stock
of which the paper is made new linen) is
boiled for hours with lime to extract the
color gluten. From the teller room we
proceeded to the engine room. Here the
stock. after it has been sufficiently boiled
under steam pressure of sixty pounds,
goes into the washing engine. At frs,
water is let in at the bottom of the engine
and is taken out at the top by revolving
cylinder covered with wire cloth, which
process goes ON till the dirt and color, az
far as it can be done by lime and water,
is removed. Other chemicals are then
added, and the "half stuff" rs the sub
stauce is then called, is thrown into watts,
where it is allowed to drain and bleach.
From these watts it goes into the beating
engine, where by long proce 81 OF grind
ing or beating it is reduced to foe pulp
or stuff, as it is technically termed. Great
care ia taken, am informed, that the
fibre of the linen is not cut short during
the process of grinding, the object being
to beat it into its finest parts rather than
to cut it short, as ia done with book and
writing papers. 1t is that which gives to
bank note paper its peculiar strength and
bladdery appearance.
At thi. st4g of the process the distri
button fibre is introduced. Through the
whole body of the paper, long and com
paratively course red fibre may be discov-
cred 1t is substance usually supposed
to be silk it is not silk-what it is WAS
not informed. 1t il cut into lengths OF
about an inch, and weigh he'd into the beat
ing engines. short time before the bsat-
ing is completed. When the stuff Is fine
enough, it is let down by a valve at the
bottom Of the engine, 20 the stuff chest in
the m4chiue room.
The loo ,lized fibre is prepared in essen
TALLY the same way, and Is Usually OF
blue color-that is let down to separate
chest on the machine. The stuff or pulp
containing the distribution fibre, passes
on to the machine in the usual way, Will;
that containing the localized fibre. by ar

continuous parallel lines, through the

These lines are % G"n'riv n ~ - bring

under calender rolls, and over steam
rolls till they are dry. 1t then pass

it is cut up into sheets by m chinery
and then goes into the 'lsy boy" After
the paper has been sized it will not do TO
dry it by steam cylinders; it therefore
goes to the drying loft where it IS hung
on poles to dry.
From the drying loft the paper goes tt
the finishing room, where it is ealondered
and counted by the manufacturers, and
thence it pisses to the upper i f. of the
mill, which is really branch of the reas.

each package, coatsining one thous ID

sheets are rejected. They are then e''nut
