Where and How Bank Note Paper is
Ma&e.

A correspondent of the Boston
| Transcript, who has visited the facto-
Ty, near Philadelphia, in which the
| Government bank note paperis made
describes the process as follows:
My first visit was Othe boiler room
! where, in large retary boiler, the
stock of which the new paper is made
! new linen) is boiled for hours with
| lime TO extract the color glutin. From
| the boiler room we proceeded to the
engine room. Here the stock, after
[ it has been sufficiently boiled under
! a steam pressure of sixty pounds, goes
| into the washing engine. 1t is then
| ground or beaten about twelve hours
/ hours in the washing engine. At
! first water is let in at the bottom of
! the engine, and is taken out at the
/ top by a cylinder covered with wire
I cloth, which process goes on till till
the dirt and color, as far as it can be
done by lime and water, is removed.
Other chemicals are then added, and
the 'half stuff" as the substance is
then. called, Is thrown into vats,
where it is allowed to drain and
bleach.
From these watts it goes into the
beating engine, where by a long pro-
cess of grinding or beating is reduced
to fine pulp or "Stuff,n as it Is
technically termed. Great care is
taken, I 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 IL short, ,2as is done
with book and writing papers. 1t
is that which gives to bank note pa
per its peculiar strength and bladdeFy
appearance.
r 4 L n
distribution fibre" is introduced
Through the whole body of the paper.
long and comparatively coarse fibre
may be discovered. It is a substance
usually supposed to be silk-it is not
silk-what it is, I was not infoFmsd.
1t is cut into lengths of about an inch
and weighed into the beating engines,
q short time before the beating is COM
pleted. When the stuff is fine
enough, it is let down by valve at
the bottom of the engine, to the stuff
chest in the machine rooms.
The localized fibre" is prepared in
essentially the same way, and is usu-
ally of blue cOlOr-that Is let down
to a separate chest, on the machine.
The stuff, or pulp, containing the dis
tTibutiOn fibre, passes on TO the ma
chine in the usual way, while that
containing the localized fibre, by an !
ingenious cOntrivance, IL made to |
flow in continued parelled lines, !
through the whole length Of the con-
tinuOus sheet.
The fires are so cOntrived as to |
bring the localized fibre into parti- !
cular part of the bond ornOte, and the !
presence of this fibre in the bond or
note is evidence of its genuineness.
This paper, while on the machine,
passes under calender rolls, and over
steam rolls, till it is dry. It is then
slit up lengthwise, and passes through (
an animal size-after that it is cut up /
by machinery into sheets, and goes
into the "l8y boy" After the paper /
has been sized, it will not do to dry it |
by steam cylinders; it therefore goes |
to drying loft, where it is hung on /
poles to dry. (
From the drying loft, the paper /
goes to the finishing room, where it !
is calendered and counted by the |
and thence il passes (
to the upper lofU Of the mill, which is |
really branch Of the Treasury De
partment. Then the paper is trim
med, examined, counted, caSed and I
sealed.
Some twenty or more women are
in examining and count
ing; each package cOntaing one thou
sand sheets, is first examined, and
all imferfect sheets are rejected; they
are then counted by one lady twice,
and her count is verified by another.
