But either fancy, or accident, or skill--it is unnecessary to decide which--has associated _symmetry_ with quality and conformation, as a point of great importance in animals calculated for fattening; and there is no doubt that, to a certain extent, this is so. The beast must be a system of mathematical lines. To the advocate of symmetry, the setting-on of a tail will be a condemning fault; indeed the ridge of the back, like a straight line, with the outline of the belly exactly parallel, viewed from the side, and a depth and squareness when viewed from behind,--which remind us of a geometrical cube, rather than a vital economy,--may be said to be the indications of excellence in a fat ox. The points of excellence in such an animal are outlined under the subsequent head, as developed in the cutting up after slaughter. Now, these qualities are inherent in some breeds; there may be cases and instances in all the superior breeds, and in most there may be failures. DRIVING AND SLAUGHTERING. It is necessary that cattle which have been disposed of to the dealer or butcher, or which are intended to be driven to market, should undergo a preparation for the journey. If they were immediately put to the road to travel, from feeding on grass or turnips, when their bowels are full of undigested vegetable matter, a scouring might ensue which would render them unfit to pursue their journey; and this complaint is the more likely to be brought on from the strong propensity which cattle have to take violent exercise upon feeling themselves at liberty after a long confinement. They in fact, become light-headed whenever they leave the barn or enclosure, so much so that they actually "frisk and race and leap," and their antics would be highly amusing, were it not for the apprehension that they may hurt themselves against some opposing object, as they seem to regard nothing before them. On being let out for the first time, cattle should be put for awhile into a larger court, or on a road well fenced with enclosures, and guarded by men, to romp about. Two or three such allowances of liberty will render them quiet; and, in the mean time, to lighten their weight of carcass, they should have hay for a large proportion of their food. These precautions are absolutely necessary for cattle which have been confined in barns; otherwise, accidents may befall them on the road, where they will at once break loose. Even at home serious accidents sometimes overtake them, such as the breaking down of a horn, casting off a hoof, spraining a tendon, bruising ribs, and heating the whole body violently; and, of course, when any such ill luck befalls, the animal affected must be left behind, and become a drawback upon the value of the rest, unless kept for some time longer.
