The food is only one item in this calculation. The oldest requires the most attention, is liable to more accidents and disease, besides the loss of interest. We are necessarily forced to the conclusion, that by far the cheapest mode of wintering pigs is in the pork-barrel. We can readily anticipate one objection to this practice, which is the want of food at the requisite season of the year to fatten them. This can be obviated, by reserving enough of the previous year's grain, to keep the animal in a rapidly thriving state, till the next crop matures sufficiently to feed. In the rich corn regions, on its beginning to ripen, as it does in August, the fields are fenced off into suitable lots, and large herds are successively turned into them, to consume the grain at their leisure. They waste nothing except the stalks, which in that region of plenty are considered of little value, and they are still useful as manure for succeeding crops; and whatever grain is left by them, leaner droves which follow, will readily glean. Peas, early buckwheat, and apples, may be fed on the ground in the same way. There is an improvement in the character of the grain from a few months' keeping, which is fully equivalent to the interest of the money and cost of storage. If fattened early in the season, they will consume less food to make an equal amount of flesh than in colder weather; they will require less attention; and generally, early pork will command the highest price in market. It is most economical, to provide the swine with a fine clover pasture to run in during the spring and summer; and they ought also to have access to the orchard, to pick up all the unripe and superfluous fruit that falls. They should also have the wash of the house and the dairy, to which add meal, and sour in large tubs or barrels. Not less than one-third, and perhaps more, of the whole grain fed to swine, is saved by grinding and cooking or souring. Yet care must be observed that the souring be not carried so far as to injure the food by putrefaction. A mixture of meal and water, with the addition of yeast or such remains of a former fermentation as adhere to the side or bottom of the vessel, and exposure to a temperature between 68° and 77° will produce immediate fermentation.
