terials which Americans have not yet
succeeded in converting into satisfac-
tory briquettes. There are experienced
engineers and a dozen manufacturers
Of briquette-making machinery VINO
would gladly cooperate In these tests
and would furnish machinery adapted
to working the material thus technl-
cally defined. Upon a basis OF such
tests, plans and estimates could be oD-
tanned for the erection of plants in the
United States with specified daily ca
racity.
The Stauber process for drying most
substances was first brought into prom
inent notice in connection with peat
coal manufacture in 1901, when the i'm
perial testing station at CharlottenpurS
announced as the result OF experiments
made with peat briquettes MADE oy tue
Stauber system that they contained
1914 per cent Of fixed carbon, 4of per
cent hydrogen, 29.34 per cent oxygen
and 900 per cent ash and had lner-
NAL value of $500 calories Ihe Stau-
her system as thus applied includes
process for rapidly drying the moist
peat by means Of heated and compress
ed air within closed chamber or chdA-
mel communicating with condult pipes
in such manner that heated air can
he forced through the drying channel
and cold air through the outlet pipe TIE
effect being that the cold air qulchly
absorbs the hot, saturated air out Oh
the drying chamber and condenses 1t III
the conduit pipes, thus greatly stlmu-
lating the process of evaporation ny
which the peat is dried. Peat III us
raw state contains from 70 to 80 per
cont of wafer and in the humid climate
of northern Europe is usually very
difficult material to dry. 1t is claimed
for the Stauber method that IL reduces
the moisture to 10 or 20 per cent quick
". effectively and, what is Important
without changing the chemical compo-
sition of the peat or in any way add-
ing to it. The drying machine IS III
the boiler form (cylindricaD and OF
size to conveniently produce five tons
of dried peat per day.
"a second process is that invented by
T Schulke of Bach strasse, Hamburg,
the salient feature Of which is that the
turf or peat used is cleaned of roots,
stones. etc, then Hquiied by water and
numned through a pipe several miles to
tho works, where, as claimed by the
inventor. it is leached and converted
nv heat and pressure into briquettes At
net cost Of 50 per ton, or into artl-
fetal coal having a thermal value OF
g o5O calories at a cost Of $2.o0 per
ton. It is understood that large plant

coast of Germany for the utilization OF
this method, but as to the actual con-
dition OF the enterprise or the prac-
teal value of the process on an indus
trial scale. no exact information is at
hand.
"The Schoening Fritz process TOR
making artificial coal and brfquettes Gy
carbonizing dried peat is an elabora
ton by a German engineer Of the sys-
tenn invented by Schoening and USED
with more or less success at Stamsund,
in Norway
"Of the processes actually employed,
the value of which has been fully es-
tablished by experience, one OF the
most interesting Is that invented by
G. Schlickeysen Of Rixdorf-Berlin and
practically operated there. at Munich
and other places. The peculiar feature
