closely to the homestead, the races of the warmer parts of the world are allowed to 

 run more or less fully at liberty. Those kept in confinement are generally larger 

 and fatter, although often more delicate animals, than the breeds which are allowec 

 to roam almost at will; the latter being longer limbed and thinner than the former, 

 but at the same time bolder and more independent in disposition. In Southern 

 Hungary, Croatia, Bosnia, Servia, Turkey, and Spain, the herds of swine are al- 

 lowed to run in the woods throughout the year, but in less warm districts they have 

 to be taken in and fed during the winter. In the Sierra Nevada of Spain, these

The different breeds of European domestic pigs vary so much that it 

 is almost impossible to classify them, and only a few of the more im- 

 portant ones can even be mentioned in this work. Many of the best 

 breeds have been produced by crossing original stocks with the so-called Siamese 

 breed, which is distributed over a great part of the Malayan region, and has been 

 imported into China. This breed (frequently termed S. indicus} is characterized by 

 its small size, cylindrical trunk, hollow back, short limbs, and the approximation of 

 the belly to the ground. The color is generally black, with the skin externally of 

 a rich copper color, and the bristles are soft; but there is also a white variety. The
