HOW PIGS WERE FORMERLY PASTURED AND FED.--Though unquestionably far greater numbers of swine are now kept in England than formerly, every peasant having one or more of that useful animal, in feudal times immense droves of pigs were kept by the franklings and barons; in those days the swine-herds being a regular part of the domestic service of every feudal household, their duty consisted in daily driving the herd of swine from the castle-yard, or outlying farm, to the nearest woods, chase, or forest, where the frankling or vavasour had, either by right or grant, what was called _free warren_, or the liberty to feed his hogs off the acorns, beech, and chestnuts that lay in such abundance on the earth, and far exceeded the power of the royal or privileged game to consume. Indeed, it was the license granted the nobles of free warren, especially for their swine, that kept up the iniquitous forest laws to so late a date, and covered so large a portion of the land with such immense tracts of wood and brake, to the injury of agriculture and the misery of the people. Some idea of the extent to which swine were grazed in the feudal times, may be formed by observing the number of pigs still fed in Epping Forest, the Forest of Dean, and the New Forest, in Hampshire, where, for several months of the year, the beech-nuts and acorns yield them so plentiful a diet. In Germany, where the chestnut is so largely cultivated, the amount of food shed every autumn is enormous; and consequently the pig, both wild and domestic, has, for a considerable portion of the year, an unfailing supply of admirable nourishment. Impressed with the value of this fruit for the food of pigs, the Prince Consort has, with great judgment, of late encouraged the collection of chestnuts in Windsor Park, and by giving a small reward to old people and children for every bushel collected, has not only found an occupation for many of the unemployed poor, but, by providing a gratuitous food for their pig, encouraged a feeling of providence and economy.
