MANUFACTURE OF PAPER.
Interesting Process Described by a
Newspaper Exporter.

of paper. All the work is done by
machinery which runs from early Mon
DAY morning through the entire week,
day and night, until Saturday evening"
and requires but few workme1 10
supervise it. The work OF modern
plant was recently reviewed by a
| Telegram representative. He found
among the other things, that in max
ing the better class of paper, for maps
and Autographs, rags are used. These
rags are gathered from all parts OF the
world by brokers in New York and arc
then reconsigned to the different
paper mills.
They are first put into thrash1ng
machine, where the sand and dirt are
thrashed out, and they pass to the
sorting table where the buttons are
pulled off and seams ripped open In
order to remove dirt that may remain.
A pair of heavy cutters cut the rags
into pieces about one and one-half
| inches wide and then follows another
dust cleaning effort
They are now ready to go into q
great, long, black boiler, eighteen
lfeet long and six feet in diameter.
lThree tons of rags are put into the
boiler at one time, strong alkal1 So
luton is poured over them and the
boiler closed up tightly. 1t is then sub
jected to steam pressure of twenty
pounds and caused to revolve conti1u-
ously for twelve hours.
When thoroughly boiled they are
taken out to dry for several days, pre-
paratory to further cleansing. The
boiling not only helps to cleanse
them, but also softens the rags. When
thoroughly dry they are put into
circular tubs, known as the washing
engines. Here the rags continually
| circulate around the tub, each circu-
lation bringing them between knives.
The tubs are filled with pure water
which, becoming dirty at each revolu.
ton, is thrown off and fresh water
taken in. This is necessary in the
bleaching process.
When in the washing engines foE
several hours, valve in the bottom
is opened and the rags drawn through
troughs to large watts in the cellar,
which are so perforated as to allow
all the liquids to escape. From the watts
the rags go into beating engine to
be reduced to fine pulp. Here the
necessary color is produced by means
of dyes. Then passing through an,
other engine, it is further refined by
having all small Jumps reduced.
The product now has the color and
thickness of pale blue SKINNED milk
and is passed into the paper machine,
to come out at the other end as a
high class paper, already rolled and
glazed.
When the small Jumps are reduced,
the milk-like substance flows in a
constant stream through a wire web
on to screen the width of the paper
to be produced. The web controls the
amount and thickness of the pulp and
makes the finished product smooth
and even.
AS the stream of pulp flows over the
screen the screen is continually shaken
from side to side, distributing the
pulp to all parts in an even manner.
This is the most wonderful part or
paper making-the changing of a thin
stream of milk-like substance into a
sheet of wet paper, and ms ely by
having the particles shaken together.
Now the paper is made. All that is
necessary Is 10 get rid of the water.

for shipment.
The wet sheet is dried by passing
through many rolls. The first roll
presses the water out of the sheet.
which, as it passes on through the
press, is subjected to roll after roll

The polish of the paper depends nm.
on the number of rolls it is passed
through. The more rolls passed
through the higher the polish ana
after this is received the paper is
wound into large rolls weighing 400
and 600 pounds each. Later this is
unwound to be cut into sheets of the
size demanded by the trade. EVERY
sheet is examined, so that if there is
any defect or blemish the sheet is
thrown aside, TO be worked over.
From the time the machine starts
running until it stops there is CON

rolls and start anew.
Water plays an important part in
the making of paper. An ordinary
mill will use about 500 gallons ~
water per minute for every minnie
OF the twenty-four hours. That is in
one reason all mills are located on tn
banks OF a stream. ARaading pa
