tire year. The logs are conveyed from
the river or cars to tho mill where
they are cut in sticks two feet long
and dropped into n vat of water to
remove the dirt. From this vat the
sticks are conveyed to the barkcrs
where revolving knives strip the bark
from each stick. The wood is re-
duced to a pulp in the grinders where
each stick Is forced against large
srlndstone which revolves at n speed
OF 200 revolutions minute, rapidly re-
duc!ng the wood fibre to a pulDy mass.
Water is freely used in this process to
soften tho wood. to wash the pulp from
the stone and keep the wood from
burning This pulp Is screened to re-
move splinters, bark and dirt and then
racked off on wet machines in laps
or large matted sheets one-quarter inch
thick This is the usual method for
storage or shipment. as from these
thick sheets the finished product Is
| rolled and finished.
In the sulphite process the wood Is
first Clipped, then crushed to break
zip all the knots and splinters. These
chips are then placed In large vat
and covered with an acid solution
which eats away everything but the
celulosc and 1t is then heated to II
high temperature by steam. After this
: process the stock Is screened and
washed and finally run over the wet
machines which consist OF cylinder
molds covered with wire cloth placed
in watts. The water Is withdrawn from
the inside of the revolving cylinders.
leaving tho fiber in n thick, soft mass
on the outer surface of the screen, from
which it Is removed by doctor ana
run into storage tanks ready for use
in tho paper mill.
1t Is in tho heater room TINT the fin
ished pulp is prepared for making the
| numerous qualities and ColOrs of paper
During the processes of beating and
mixing the color Is added to produce
the shade desired Then the rosin size
Is added to give the necessary nonab-
sorbng qualities and sufficient alum is
nut in to set the Colors. After leaving
this room the stock Is called "Stuft'
and is run into stuff chests. From the
stuff box the pulp Is put through the
| Jordon engine which mixes 1t thor
oughly, and 1t is ready to be made
! into tho finished product. The paper
| stuff after being screened again Is run
| through the Fourdrnier paper machine,
which consists of the following parts:
| 1, screen: 2, the wire. with dandy
| roll. deckle straps and suction box:
| 3, couch rolls: 4, first press: >. second
| nrass. third press; the driers: s,
| the calendcrs: .. tho reel; 10, the sitter
and II. the rewindcr.
Reliable power service and uniform
speed are essential to the satisfactory
| manufacture of paper. for when Il run
| Is started II must be continuous ana
nny variation of speed seriously affects
the quality OF the paper. Electricity
has been found to be the ideal power
! for this service, as 1t gives great elias
| tcity and reduced friction losses by
eliminated belts and shafting. In the
large paper manufacturing plant at
I.ockport, N. Y. equipped electrically
| throughout BY the General Electric
company, 100 electrical horsepower Is
doing the work formerly done by Lou
| steam horsepower, for more than a2s-
horsepower were required to turn the
| large amount of belts and shnftlng UNI
| dor the old steam power system.
The census for 1905 shows 759 paper
making establishments, producing an
| nually 2.20G,O4S tons of piper. the most
OF which is used in newspapers and for
! wrapping purposes.-Clevoland Plain
