HOW PAPER Is MADE.
Everybody Uses. But Few Know
About Paper.-Idaho U.
Man Enlightens Us.

such a common article it seem
everyone should know all abou
it. But do you?
Carl H. Norlin, an advances
student in chemical engineering
at the Idaho University, gives
concise story Of its manufactur
at the Wildwood plant near Spo
kane. This story, which appear
ed in last Sundays Spokesman
Review, is as follows:
TIMBER" The warning cry
sounded across the valley; two
lumber jacks leaped away from
the four-foot fir through which
their big saw had been slicing,
and the big tree came crashing
to-the ground, somewhere in the
big woods Of Idaho.
AT Wildwood paper mills this
tree was started on its public ca
reer as print paper. Here it was
flattened into ribbon % miles
long, IL feet wide and three thous-
andths of an inch thick. Every
day in the year except Christmas
and the Fourth of July the paper
mill at Wildwood makes so tons
of newsprint paper.
Since the ribbon comes from the
rolls Of the paper machine at the
rate of 600 feet a minute, the daily
output would be 146 miles long,
and the whole years product
would very nearly belt the earth.
As cordwood the trees arrive at
the paper mill and are rapidly
ground to pulp on large grind
stone. A jet of water washes
away the pulp, which resembles
potato soup in texture and APP
pearance, and carries it through
fine screen. 1t is picked out of
the water by machine and form
ed into thick sheets, which, in
turn, are run through the beating
engines -oblong tubs, fitted with |
revolving knives, that chop and
beat the pulp to a smooth, frothy
looking mass. In these heaters a
resin size" is added to it in or
der to make paper on which the
ink will not run. After repeated
beatings, the trees, now in the
form Of thin, smooth paste, are
pumped to reservoir, from which
they are fed to the "Fourdriniern
machine.
The Fourdrinier machine is the
actual paper maker. It is the ma
chine that makes the modern
newspaper possible. According
to a statement found in the libra
ry of the department of chemis-
try at the University of Idaho, it
was invented in 1900 by Louis
Robert, a worker in French pa $
per making shop. An English pa h
Der manufacturer named Henry y
'ourdrinier perfected it and in o
reduced it into England. It has q
lnce borne his name. Before 8
'ourdrinier's time all paper was !
made by hand, one sheet at a y
lme. His machine makes it in p
ontlnuous sheet or ribbon. II
Paper is a thin sheet of veQeta- I'll
