So much for feeding qualities in the animal, and their conformations indicative of this kindly disposition. Next come such formations of the animal itself as are favorable to the growth of fat, other things being equal. There must be _size_ where large weights are expected. Christmas beef, for instance, is expected to be large as well as fat. The symbol of festivity should be capacious, as well as prime in quality. But it is so much a matter of choice and circumstance with the grazier, that profit alone will be his guide. The axiom will be, however, as a general rule, that the better the grazing soil the larger the animal may be; the poorer the soil, the smaller the animal. Small animals are, unquestionably, much more easily fed, and they are well known by experienced men to be best adapted to second-rate feeding pastures. But, beyond this, there must be _breadth_ of carcass. This is indicative of fattening, perhaps, beyond all other qualifications. If rumps are favorite joints and produce the best price, it is best to have the animal which will grow the longest, the broadest, and the best rump; the same of crop, and the same of sirloin; and not only so, but breadth is essential to the consumption of that quantity of food which is necessary to the development of a large amount of fat in the animal. Thus, a deep, wide chest, favorable for the respiratory and circulating functions, enables it to consume a large amount of food, to take up the sugary matter, and to deposit the fatty matter,--as then useless for respiration, but afterwards to be prized. A full level crop will be of the same physiological utility; while a broad and open framework at the hips will afford scope for the action of the liver and kidneys. There are other points, also, of much importance; the head must be small and fine; its special use is indicative of the quick fattening of the animal so constructed, and it is also indicative of the bones being small and the legs short. For constitutional powers, the beast should have his ribs extended well towards the thigh-bones or hips, so as to leave as little unprotected space as possible. There must be no angular, or abrupt points; all must be round, and broad, and parallel. Any depression in the lean animal will give a deficient deposit of flesh and fat at that point, when sold to the butcher, and thus deteriorate its value; and hence the animal must be round and full.
