various woods for the usual materials will De
noted at each stage of manufacture
Both soda and sulphate processes OF treat
ment of the chips will be used and the iap
oratory will make its own sulphre nquor IN
vat adjacent to the digestors, In which the.
wood is cooked by steam until the lignin Is
all dissolved and only the cellulose le1t'
blast of highpressure steam drives the chips
against the side of the digestor, further III
yiding the cellulose fibers and then the Whoie
mass is pumped out by centrifugal pump
into tank in which 1t is stirred until the
fiber is still further broken up. over ana
over II is run through "riffer' troughs and
over screens where suction draws out the
finer to be used and leaves behind the small
chips. splinters and other waste.
When the liquor has been washed out OF
II in washer driven by an electric motor VA
contrivance much like the housewives WASH
ing machine) 1t is put into press ana tne
water Is squeezed out of 1t. Such or the pup
blocks from the press as are not wanted iIi'
noediatelv are then in convenient form to store
away on shelves
After going through the beating engines
the refined pulp is run on to the screens OF the
paper machine and taken up by felt roiiers'
from which 1t goes to wooden rollers ana tnen
between metal rollers to the steath-hea'eu
driving drums where the wet sheet Is run pack
and forth until it is ready for the maj sihooIh
finish of the hot steel calendering rolls. ANY
,,rode of naper can be made on this machine,
from the toughest brown paper TO me COT
respondence paper, in a running sheet 10
inches vide and even water-marklng device
&c attached so that the impression can be
made on the wet sheet before 1t goes through
the rollers and on to the winding drum at the
end.
How to make timber last longer by protect
ing it with preservatives from the various
horers and fungous growths when atlacf

which considerable time and laboratory space
are to be given
