MAKING 1t may be well first to detail
sne methods employed in the manu-
1acsu!e OF news paper. The materials
useo IN US manufacture are q combine
ton OF bi-sulphite, or chemical vooa
pulp. rags and ordinary wood puln
the latter being known principally =.
Mechanical pulp The first named
artlcie. bi-sulphite pulp, is made bv a
com olnatlon of chemicals acting upon
WOOD which produces a pulp possess

purpose OF adding to its STRENGTH,
ana durability. The process 81
manufacturing this chemical puln ia :.
most intricate one, and Is considered a.
one OF the secrets of the trade. Thu.
process of manufacturing mechanical
pulp is very simple one, and is as fol.

The cottonwood from which IL ia mad.
IS received from the forests in reoul.-
-cordwood lengths These sticks are
sawed into lengths of about eighteen
inches They are then run throuoh y
'shaving-machiue which takes off ali
the bark and leaves the stick perfectly
clear. These sticks are then ready for
the grinders.
The grinders have upper and lower
pockets into which these sticks of wood
are packed. The wood is fed down
from these pockets into the grinding
stones, where it is ground into puln.
There Is continual stream of water
running into the grinding-stones. and
this mixes with the wood "a II :.
ground, and the mixture flows into
large watts underneath the machines.
From these watts the mixture is pumne,l
up stairs and then rolled through a ma.
chine upon sheets, ready for use j.,
combination with the bi-sulphite and
rags in the manufacture of news paper.
The rags are subjected to a more
elaborate treatment. before they ara
ready for use. They are first run
through a cutter one or more times.
as may be deemed necessary. This
is to shred them as much as
possible. They are then placed in huge
vats OF lime-water and allowed to soak
for twenty-four hours or longer. in
order to soften them and remove all
harshnesa After coming from these
watts they are placed in the bleaching
fluid, and when thoroughly saturated
with this fluid they are placed into
large tanks or watts, where they remain
long enough to become bleached white
and to dry out to a certain extent.
The three articles, now being ready,
they are mixed in the proper proper
lions and run through what are termed
batting engines. The bi-sulphite, the
rags and the mechanical pulp are
thoroughly mixed in these beating en-
gines, and while mixing the sizing and
coloring are put in. The mixture is
conveyed from the beating engines
through refining engines, and thence
into large watts, from which the paper
machine is fed.
The machine is nothing more nor
less than a great many rollers of vari-
GUS sizes, SO adjusted and arranged
that after the pulp mixture has passed
through, around and between all these
various rollers it comes off in finished
state, wound upon hollow iron cores
ready for adjustment on perfecting
presses. The news paper intended for
use on other styles of presses is run off
from these rolls through a cutting ma
chine, where it is cut into the desired
sized sheets and packed ready for ship
ment.
The straw from which straw paper
is made is first soaked in lime water
the same as the rags It is then sub
jected to the same treatment that the
mixture of bi-sulphite. rags and wood
pulp is for the manufacture of news
paper, after which it is conveyed to
watts from which the machine Is fed
The straw and MANILA paper made by
the company is manufactured on ma
chine capable of turning out sheet
ffty-two inches wide, the capacity be-
ing FIVE tons per day. The MANILA pa
per is made entirely Of old rope, burlap.
= etc. The material is first run through
one cutter in the same manner that the
rags are, after which it is subjected to
the same treatment that the straw is
before it is ready for the paper ma
chine. The machine upon which the
news paper is made has a capacity of
six tons per day and turns out sheet
eighty-six inches in width. About
three thousand cords of wood per an
mum are used by the mills in the man
ufacture of pulp alone.-Portland Ore
