76 SWINE 



In color these three breeds are somewhat different. 

 The Neapolitan is black, slate or ash color, and sometimes 

 a dirty white and more or less spotted. The Siamese is 

 of a dark slate or rich plum color. The Chinese may be 

 either white or black, or a mixture of both, with white 

 predominating. These three breeds, and possibly others, 

 which illustrate the Sus Indica type, apparently have 

 been bred for many centuries in southern Europe. 



Production of Breeds. In comparing this hog (Sus 

 Indica type) with the northern type of animal, the Sus 

 Scrofa, the question naturally arises what was the first 

 origin of these two types of hogs. The assumption is 

 that these two types naturally trace back to the same an- 

 cestry. The difference in them, then, is the result of en- 

 vironment as produced in different localities. The hogs 

 of the south have an abundance of food which, together 

 with the environment under which they live, would have 

 a tendency to develop the qualities of early maturity and 

 fat-producing tendency and also to reduce the size. Those 

 of the north where food is more scarce would develop to 

 the other extreme. 



The northern civilization of Europe in its present form 

 is much more recent than that of the south. The north- 

 ern hog, therefore, is comparatively a modern hog. Con- 

 sidering that he is the natural outgrowth of the wild boar 

 of the Sus Scrofa type which was found in northern 

 Europe, it can readily be seen that this would produce a 

 .hog materially different from the highly improved types 

 found in the south. 



During the early history of Great Britain conditions 

 were especially adapted to the production of different 

 breeds. Transportation facilities were inadequate, tele- 

 phone and telegraph communication were unknown, and
