Early History. — The early history of the breed is quite obscure. 

 The first definite records of the breed show that the Small Yorkshire 

 was in existence about 1818. At that time Charles Mason and 

 Robert Colling, of Yorkshire, England, were breeding a small white 

 hog, which was known as Chinese White. The ancestry of the 

 stock owned by these breeders is unknown. 



Following this time the breed became rather widely dissemi- 

 nated throughout England, appearing to be particularly popular 

 with breeders of short-horn cattle, a fact that is largely explained

by the fact that Mason and Colling were well-known short-horn 

 breeders. These Chinese hogs appear to have been crossed with 

 other small white breeds prevalent at that time in England, such 

 as the Solways, Cumberlands, and White Liecester. As a result, 

 there was some gain in size and vigor by the breed. The select 

 types derived from crossing of these strains is believed to represent 

 the foundation of the present Small Yorkshire type. 



The breed, from its many showy points, has long been a favor- 

 ite with the noblemen of England for show-ring purposes. In the 

 English shows the breed is also referred to as the Small White hog. 

 The first importations into America are a Uttle indefinite. There 

 is a more or less obscure record of the breed in the United States
