yEE MATERIALS FOR PAPER.
PAPER OF STRAW

from straw ana ob'I h"' substances was made n
1865. There are yet c,ant few copies OF treatise pub
lished by j. q sch5fer. Doctor IN Theology, at Rsts
bo-,o i,e5 from which the following is an eEtrsc,:
Wherens the ~ are 10 be had in quantity adequate
10 the vents Tor the manufacture OF paper have though
that any plants banks Of trees could be used WIN az
ventsge 10 that purpose and have tried 20 obtain the
rure 6ber. from many of them, in which succeeded en-
rey a. can be by the specimens which are annexed

Tho treatise itsef is printed white boxing paper
made from straw but the process given up a. too
expensive.
A few wear. later the chenis: Dese succeeded IN
bleaching the bark of tic mulberry tree but failed with
straw That kind of bark could not be procured in sui
e. Mt quantities and the process abandoned II vs.
not until twenty-five YEAR, had elapsed that trials
were made. segun obtained patent in France in l-ol
Msthie, Koop got another in England in 1902 and Resb
and Guesor another shortly alter for the manufacture
straw pulp. Koop's process was tie following
Cut the straw two inches long, boil IN water in tue
proportion OF two gallons per pound Of raw. Aiter
Las been drained make II soak IN hme-waec during etsh
days Using pounds Of lime for Of straw and re
neat the operation egain and again till the straw
i sufficiently sofened lfamoe agreeable color wanted
fo every pound of straw Ne three OF crystals OF soda after
tbe straw has been washed
This process far from furnishing white pulp did not give
as good paper the wrappers of time. These
ursuccessfu experiments made ~ time when the war
then raging in Europe prevented England from importing
rpcs from the continent, dGmfcd the spirit Of invention
for nearly twenty years. At length the subject was re-
viyed and in France patents granted To- " DessanI
in Isis VI. Hiroren in 1870, Bronzac in l-e+, and to
NJ Polar in l725. In the meantime revolution had &C.
cured in papermtking-a machine had been invented,
re.ec;ed and generally introduced producing twenty
tines more paper than could be made by hanff and with
little manual lebor An Impulse now given to pro
duoiion and more materials wanted and according
j. tie process Of bleaching improved and goot paper
wGt made Of What before considered az refuse or al
beet fit only for making pas,ebcard. Bur Notwithstanding
these improvements researches after substitutes for rags
were never abandoned From 1873 10 1919 the number
Of patents granted Europe Cor bleaching straw was one
hundred esd ilityseven Every one Of the processes
described in tiese patents hes completely ailed. TIC
last nevertheless deserves mentioning IL was granted 10
Samuel W. Wright Of Massachusetts, the process wds
mainly mcdaniel, and good wLe paPer was ~, ~, ,..r.
great excitement wds creaiei By it, licences were s,d
in Europe and machinery waa built in England and
France bu, after a short time it abandoned as too
expensive.
Mr. MelNer the inventor Of process coming into
usc corrected paper maker with the working OF
S. W. Wrghts process in France, and after its failure
wont experimenting several of the previous patents,
til finally be associated himself with Mr. T. Coupler aud
by their united efforts they discovered the process lately
patented in this country, Us well cs in Europe which is
the following:
The straw is Gu. one inch long and the knots ears
and grains are separated by wnnowng. 1t il then thrown
into large wooden iron tub, and strong boiling sou-
ton Of caustic soda il poured upon IT, This drawn at
tie bottom, again warmed by steam and again poured
uIon the straw which operation is repeated TIL the straw
becomes s)oDgy. The straw is then washed, first with
warm water TO take the soda and then with cold water
to cool it, II is beN taken out and thrown into strong
bleaching liquor wheie has TO be stirred up every hour
to make Ire liquor act uniformly From there the pulp
is Let down to the drainers IN state called technically
lasuif. and II ready for the beating engines
To perform the above simple operations good many
things are required:
l. Iron cistcrns for the preparation Of causC soda
3 Stone cisiCrDs for preparing bleaching liquor
B. reyerberatory furnace to recover tso-thds OF the
soda.
l. Apparatu. TO throw uniformly the solution over the
straw.
large steamboior, a SINAI! steam. engine, and
limited supply Of water also absolute requisites.
About forty eight hours required to make the straw
ready for beating quantity Of straw, wet hing 400
pounds will weigh, after cutting and wnnowng, 1000
pounds end after bleaching will produce 1000 pounds of
paper The fbers of the straw pulp are more uniform
tlpn those Of rags and instead OF hours beating re-
quiie only q hours.
The cost OF establishing the special apparatus for max
ing straw pulp in mill of ordinary size-say producing
two tuns of paper days under five thousand dollars,
beside the necessary building. The price of new mill
and par. of the power &c necessary would be dis
pensed with The cost Of straw-pulp, ready for the
beating engine warranted by the inventors to be only
twohirds that of ragpulp of the quality and they
are ready to treat with manufacturers on that basis
There is great difference of opinion among paper
makers about the Of ragpup and about the proper
ton ost in working their statements varying between
IS and per cent We will endeavor to prove any
fling BY figures but i'll merely give the data respecting
strawrup. To bleach 800 pounds of .traw and obtain
1900 pounds Of paper, there used:
soda rs............. SEQ BIZ aehrs Powder, bs....looo
Line Ibis '.''''.. Labor hHen.'''''..''.'''. Il
The quantity Of soda tlrown upon the straw il in reality
200 pounds which uniting with the gum Of the straw
forms soap, but by evaporation and burning, this soap
is cccomposed, and sOO pounds Of soda recovered
making the loss only 800 pounds
Coupler Meliers process has been in successful ope
ration for three years in Ireland England and France
the pTeudcos against wearing away and for the last
two months the Paris newspaper La P,o.e, has been
printed upon straw poIer. We confidently hope that It's
introduction into the United States will take les. time
From III 10Th April he 10Th Of June paper for
Tic Philadelphia LC3cc was made from straw b. Mr.
Mci;cr at tic Fiat Rock Mills in Manayuuk Since that
Zine the manufacture has been successfully and proitlby
