The hog, that finds his food among ordure, and greedily devours many things rejected by every other useful animal, is, like poultry, originally kept as a save-all. As long as the number of such animals, which can thus be reared at little or no expense, is fully sufficient to supply the demand, this sort of butcher's meat comes to market at a much lower price than any other. But when the demand rises beyond what this quantity can supply, when it becomes necessary to raise food on purpose for feeding and fattening hogs, in the same manner as for feeding and fattening other cattle, the price necessarily rises, and becomes proportionably either higher or lower than that of other butcher's meat, according as the nature of the country, and the state of its agriculture, happen to render the feeding of hogs more or less expensive than that of other cattle. In France, according to Mr Buffon, the price of pork is nearly equal to that of beef. In most parts of Great Britain it is at present somewhat higher.
