Cattle are made to fast before being slaughtered. The time they should stand depends upon their state on their arrival at the shambles. If they have been driven a considerable distance in a proper manner, the bowels will be in a tolerably empty state, so that twelve hours may suffice; but if they are full and just off their food, twenty-four hours will be required. Beasts that have been overdriven, or much struck with sticks, or in any degree infuriated, should not be immediately slaughtered, but allowed to stand on dry food, such as hay, until the symptoms disappear. These precautions are absolutely necessary that the meat may be preserved in the best state. The mode of slaughtering cattle varies in different countries. In the great slaughter-houses at Montmartre, in Paris, they are slaughtered by bisecting the spinal cord of the cervical vertebrae; and this is accomplished by the driving of a sharp-pointed chisel between the second and third vertebrae, with a smart stroke of a mallet, while the animal is standing, when it drops, and death or insensibility instantly ensues, and the blood is let out immediately by opening the blood-vessels of the neck. The plan adopted in England is, first to bring the ox down on his knees, and place his under-jaw upon the ground by means of ropes fastened to his head and passed through an iron ring in the floor of the slaughterhouse. He is then stunned with a few blows from an iron axe made for the purpose, on the forehead, the bone of which is usually driven into the brain. The animal then falls upon his side, and the blood is let out by the neck. Of the two modes, the French is apparently the less cruel, for some oxen require many blows to make them fall. Some butchers, however, allege that the separation of the spinal cord, by producing a general nervous convulsion throughout the body, prevents the blood from flowing as rapidly and entirely out of it as when the ox is stunned in the forehead. The skin is then taken off to the knees, when the legs are disjointed, and also off the head. The carcass is then hung up by the tendons of the hough on a stretcher, by a block and tackle, worked by a small winch, which retains in place what rope it winds up by means of a wheel and ratchet.
