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

If only the edible portions of slaugh- tered animals could be utilized, meat would be luxury Ind at high figure, since only about one-third of the weight of the animal consists of prod rcts that can be eaten. The utilization of the waste products of large npat- toirs as in Chicago, where no fever than9, ,0000stcers,1 ], ,000calves, 1, Is, ,0o0 hogs and 6.OOO sheep have been received il [, single day, becomes matter of con siderable importance. The market value of the by-products represents an enormous sum, and the concentration of small products that a butcher would allow to go to waste. In the process of slaughtering the cx is killed by the, blow of a hammer on the head. The iugular vein ard carotid artery are cut, permitting the escape of the blood, which is collected. When cold it CO., agulates. The fluid portion, contain ing soluble salts, is liberated. It is crnpioyed fer sizing paper. The best qualities oi blood are usSd in refining sugar. Tkc sugar contains many inn purities. When dissolved in solution of water and pure OK blood and heated. the alhumen of the blood rises as q scum and carries the impurities in sus- pension. The sugar is afterward fil- 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 tor 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, intestines, etc, are separated into the parts that go to the drying-rcom, 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. Residue parti- 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, its use also by the perfumer and druggist for GOV ering corks of bottles.
 The guts, which are treated in sinii- 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 nilli- meter. This delicate membrane formed from the external membrane ! of the large intestine of the OK, is of particular value. It is used in surgery for closing wounds and for making plasters. Glue is made from the coarscr and gelatine from the finer parts of such by-products as parings of l skins, the ears, portion of the tail, the l 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 cheaI
 'camels" 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 hail removed in making glue is burned in z closed vessel. and serves for the manu fracture of ammonia, used extensively in refrigerating machines. Even tn, undigested food in the stomach hay and Indian corn, is compressed ant
 dried. and forms food known a. Texas nut.s The young calves fur nish the rennet used in cheese, etc. Tn bile (ox galD is used for cleaning ant painting and binding. Large quanti
 ties of excellent fertilizing materia
 are produced from miscellaneous offal
 The same by-products. are obtained from the hog as from the oxy with pep sin and bristles in addition.-Scientiii
