SLAUGHTER HOUSE WASTE.
Utilization of the Non Edible Por-
tons of Butchered Animals.
Many Useful Articles of Commerce Made
from the Discarded Scraps and
Gore of the Strengthening
Pens.


If only the edible portions of slaugh-
tered animals could be utilized, meat
would be a luxury and at high figure,
since only about one-third of the
weight of the animal consists of prod
ucts that can be eaten. The utilization
of the waste products of large abat-
toirs as in Chicago, where no fewer
than9, O000s H. OOcalves, 1000 hogs
and 5000 sheep have been received in
single day, becomes a matter of con-
siderable Importance. The market
value of the by-products represents an
enormous sum, and the concentration
of small products that butcher would
allow to go to waste. In the process
of slaughtering the OK is killed by the
blow of hammer on the head. The
jugular vein and carotid artery are cut,
permitting the escape of the blood,
agulates. The fluid portion, contain
ing soluble salts, is liberated. 1t is
employed for sizing paper. The best
qualities of blood are used in refining
sugar. The sugar contains many i'm
purities. When dissolved in a solution
of water and pure OK blood and heated,
the albumen of the blood rises as a
scum and carries the impurities in sus-
pension. The sugar is afterward FL
tered through cotton and then bone
black. The latter is also a product of
the abattoir, being made from calcined
bones. Inferior qualities of blood are
used for many purposes, as in the man.
ufacture of buttons, which are hard to
distinguish from hard rubber ones.
The poorest quality of blood mixed
with other by-products is used as a
fertilizer. The skin is converted into
leather. The portions of the stomach,
lntestines, ETC., are separated into the
parts that go to the drying-room, the
portion that enters into the compost
ton of fertilizers, and also that which
is to be converted into oil and then into
margarine and butterine. Residuepar
cles of meat and fat are collected and
sold to manufacturers of axle grease,
soap and candles. The bladder is
cleaned, inflated, tied, dried, and sold
to manufacturers of mastic, snuff, etc.
As the bladder is impermeable no
evaporation occurs, hence, it's use also
by the perfumer and druggist for COW
ering corks of bottles.
The CUTS, which are treated in SINH
lar manner, are glued together end to
end and used in breweries for lining
pipes, so as. to prevent the beer from
coming in contact with the metal. The
intestines are also prepared for gold
beaters' use, in which alternate layers
Of skin and gold leaf are beaten to
about one ten-millionth of a MILL
meter. This delicate membrane
formed from the external membrane
Of the large intestine of the OK, is of
particular value. 1t is used in surgery
for closing wounds and for making
plasters. Glue is made from the
coarser and gelatine from the finer
parts of such by-products as parings of
skins, the ears, portion of the tail, the
feet, the muzzle, the bones of the skull
and jaws, and the interior of the horns.
The hair from the interior of the ears
Is very fine and used in making cheap
"camel's" hair brushes. The feet, freed
from the horn, serve for the manufac-
ture of an oil used to dress leather.
The horns can be heated, welded, split,
colored, nodded, etc, and initiate
many well-known objects. The hair
removed in making glue is burned in a
closed vessel, and serves for the manu-
facture of ammonia, used extensively
in refrigerating machines. Even the
undigested food in the stomach, hay
and Indian corn, is compressed and
dried. and forms a food known as
Texas nut" The young calves fur
nish the rennet used in cheese, etc. The
bile (ox galD is used for cleaning and
painting and binding. Large quanti-
ties of excellent fertilizing material
are produced from miscellaneous offal.
The same by-products are obtained
from the hog as from the OK, with pep
sin and bristles in addition.-Scientific
