=Horns.=--Horns are the most valuable bone products measured by weight. Owing to the dehorning of cattle as well as the breeding of polled cattle, the supply of horns has been greatly diminished, and whereas twenty-five years ago horns were worth $20.00 a ton they are now worth from $280.00 to $300.00 per ton if they are of the proper selections, hence it will be seen that intelligent handling is worth while. The horns severed from the head preferably by sawing and cutting at a point beyond the meeting point of skull and horn, are thrown into a vat of water, held at a temperature of from 140° to 150° F. After soaking for ten or fifteen minutes they are taken out and by hammering the horn across some solid substance, or by laying it on a block and pounding it with a weight or mallet, the pith slips out. The piths are dried and used in the manufacture of glue. The horns should be stored in a room where there is ample outside air circulation and not too dry. Artificial heat will cause them to crack. They are never dried on steam coils. Selections are made for some markets, although they are usually sold as taken off. =Manufactured Articles.=--The manufacture of horns into manufactured articles is a highly specialized work and rarely undertaken by the packer as a commercial possibility. Horns are used for the manufacture of combs and various other ornamental articles. In the course of manufacturing, the tip is sawed off to the hollow part of the horn. It is then split open, the horn is steamed, softened and flattened by pressure, usually hydraulic pressure. Any checks or flaws in the horn damage it for manufacturing purposes. If submitted to excessive heat in drying or stored in a room that is hot and dry they are sure to become damaged. When in storage they should be placed in a cellar or room where there is some moisture, but not enough to cause them to mold. [Illustration: FIG. 60.--CATTLE HEAD SPLITTERS.] =Skulls.=--The treatment of skulls in process is as follows: The cheek meat is removed from the head, the jaws pulled out, the head split and brain removed, and the skull is ready for the cooking vat. The brain is an edible product, for which there is a ready sale in most markets, consequently they should be properly taken out. The illustration, Fig. 60, is of a machine with a hollow knife intended for splitting the skull but not damaging the brain. With this machine the heads are split after the jaws are pulled. The head is laid on the table with the teeth up. The knife is made with a semi-circular space in the sharp edge which comes down over the brain without touching same as the balance of the blade is forced through the skull, leaving the brain intact while separating the skull bones. Where a large number of heads are handled in this manner it saves a great deal of labor. It is desirable to remove the brains before cooking the skulls, as the bones become discolored if the brain is left in the skull.
