By slow stages of animal improvement the ugly

By slow stages of animal improvement the ugly, thin-flanked wild boar of early times has been transformed into the sleek Berkshire or the well-rounded Poland-China. In the same manner the wild sheep of the Old World have been developed into wool and mutton breeds of the finest excellence. By constant care, attention, and selection the thin, long-legged wild ox has been bred into the bounteous milk-producing Jerseys and Holsteins or into the Shorthorn mountains of flesh. From the small, bony, coarse, and shaggy horse of ancient times have descended the heavy Norman, or Percheron, draft horse and the fleet Arab courser.
