No one who lives in the country is ignorant of the profits arising from the hog; his flesh sells for more than that of the ox, and his lard for nearly double; the blood, intestines, feet, and tongue, are all prepared and used as food. The dung of the hog is colder than that of other animals, and should not be used for any but hot and dry lands. The fat of the intestines and web, which differs from the common lard, is employed for greasing wheels, and many other purposes. Sieves are made of the skin, and brushes and pencil-brushes are made of the hair and bristles. The flesh of this animal takes salt better, and will keep longer than that of any other.
This species, though very abundant, and greatly spread over Europe, Asia, and Africa, were not found on the New Continent till they were transported thither by the Spaniards, and who also took large black hogs to almost all the islands of America. They have become wild, and multiplied greatly in many places: they resemble our wild boars, and their bodies are shorter, their heads larger, and their skins thicker than the domestic hogs, which in warm climates are all black, like the wild boar.
By one of those prejudices which superstition alone could produce and support, the Mahometans are deprived of this animal; having been told hogs are unclean, they do not either touch or feed on them. The Chinese, on the contrary, are very fond of their flesh; they raise numerous herds of them, and pork is their principal food; and this circumstance is said to have prevented them from receiving the law of Mahomet. The hogs of China, Siam, and India, differ a little from those of Europe; they are smaller, have shorter legs, and their flesh is much more white and delicate. Some of them have been reared in France, and they will intermix and produce with the common hogs. The negroes raise great numbers of hogs, and though there are but few among the Moors, or in the countries inhabited by the Mahometans, yet wild boars are as plenty in Africa and in Asia as in Europe.
Thus these animals are not confined to any particular climates; it is only observable, that the boar, by becoming domestic, degenerates more in cold than in warm climates. A degree of temperature is sufficient to change their colour. Hogs are commonly white in the northern parts of France, as they are in Vivarais, while in Dauphiny, which is not far distant, they are all black; those of Languedoc, Provence, Spain, Italy, India, China, and America, are also of the same colour. The hog of Siam has a greater resemblance than the hog of France to the wild boar. One of the most evident marks of degeneration is furnished by the ears, which become more supple and pendant as the animal changes into a domestic state; in short the ears of the domestic hog are not so stiff, are much longer, and more pendant than those of the wild boar, which ought to be regarded as the model of the species.
