MAKING rASNrs EXTRACT.

superintendent OF the niiap4 H4inoi
tannin extract company, your cure
spondent was lately shown through their
new plant at this place. The expense OF
this establishment Is $4,000. The ma
chinery is all in place except the engine
This engine is 20 horse power, but only ~
or 80 pounds of steam will be require TO
operate the machinery. They expect TO
start up business about the 10Th instant
some 7O1 cords Of henilock bark are now
under cover ready for consumption.
Hemlock timber grows in abundance on
this harbor. Bark peeling begins in May.
The bark costs So per cord delivered.
GRINDING THE BARK.
The bark is broken up and put into a
large iron hopper and is ground very
fine, after which it is carried into .arge
teaches by elevators. here are five OF
these teaches, with capacity OF lJ.OOo
gallons each. As the bark is being de-
posted in these teaches hot water is dis
tributed upon it by means OF long
brass pipe containing many small holes,
placed in horizontal position. with its
center resting on perpendicular bar set
in the center of each leach. This hori-
zontal bar whiIls round and round, thus
distributing the water very evenly.
SOAKED FOR Sc HOURS.
After the bark has soaked SO hours the
astringent principle is run off and carried
by pipes into copper concentration, hold
ing 40 barrels, where it is subjected to
great heat and boiled TO about the con-
sistency Of molasses. Ii is reduced 81
times. or in other words is made 30 times
stronger than when run into this vessel.
The tannin must be made very strong
in order to keep it from fermen'ing and
spelling. This condensing also makes it
cheaper to ship. This copper concentraror
costs 1920 in New Jersey, and the freight
to South Bend was $50. After the liquid
has been drawn from the leachs the bark
is taken out and constitutes all the fuel
used in running the engine.
MARKETING THE EXTRACT.
| The extract made from the bark now
on hand will oe shipped by water to san
Francisco. The market on this coast is
limited at present. Mr.. Miller says they
have a contract with Mr. Bruntch Of
Hamburg, Germany. by which he is to
have the entire produat Of this establish
ment. He will have line of sailing
vessels constantly playing between Ham
burg and South Bend for lumber and tan
min extract.
| BARRELS FOR THE TANNIN.
A cooper shop is in connection where
all barrels used are made. spruce is used
in their manufacture. Each barrel costs
the company sl.65. They are made by
the piece, at IS cents each a goud work
man will make fiom four to five barrels a
day. The hoop-iron and paint for barrel
costs 30 cents. Tie factory will be oper-
ated day and right and will give employ
ment to 20 men regularly, and in peeling
season 1v0 men will be engaged.
The capacity will be 150 barrels OF ex-
tract per week. One cord OF bark will
make barrel of extract. Each barrel
holds 50J pounds or 50 gallons. The ex-
tract sells at three cents per pound Or SIS
per barrel.
WHITE HEMLOcK is USED.
The character Of the hemlock in the
| vicinity of south Bend is almost entirely
what il known as "white hemlock" and
makes a very superior light colored ex-
tract which tans the leather a color that
can hardly be distinguished from oak tan.
The hemlock of Washington is exceed
ingly rich. A recent analysis by one Of
the leading leather chemists Of the Unit
ed states, j. H. Fiebing Of Milwaukee,
shows that the hemlock Of this state car
| ries l7.S per cent tannin, while that of
Eastern states will not averagh over 10
per cent.
COMPETENT SUPERINTENDENT.
Superintendent Miller has had good ex-
perience in establishments of this charac.
ter, having been engaged in tine business
all his life. He was with one firm in the
Fast % years and is thorough master
Of the art. This is an establishment that
south Bend may we'll b. proud Of. 1t will
materially aid and haatan the "a ncl,a "a II,
