There are many breeds of swine highly recommended. Some of the varieties of the Chinese are the most prolific and have the greatest tendency to fattening of any known. They have formed the basis of the great improvements in the breeds in Great Britain. Farmers will be able to select the best breed from their own knowledge and observation, better than from any directions we can give them. Every new variety will be introduced by dealers, and farmers must be cautious how they accept their representations. _Age of Swine for Pork._--It is most profitable and least troublesome, to keep over winter, no swine but breeding sows, to have pigs early in spring, to kill in autumn. Of any of the good breeds, they can be made to weigh from 300 to 350 pounds, by the proper time for killing. The practice of keeping swine till eighteen or twenty-four months old, and only fattening them late in the fall and beginning of winter, is very unprofitable. It is best to give pigs about what they will eat, from the time of beginning to feed them until they are slaughtered. This is in every way most economical. It secures fattening in the hot weather in summer, when pork can be made faster and cheaper than at any other time. Many farmers begin to fatten their pork, after the season in which it can most rapidly and cheaply be done. Hogs having been kept poor, on being fed freely for fattening, become cloyed, and much time is lost, while those that always have had what they would eat, of good wholesome food, always have a good appetite for as much as they need, and not root over and injure more.
