(3) The Ohio Improved Chester White. — This strain developed 
near Salem, Ohio. It owes its origin to L. B. Silver, who in 1865 
began breeding Chester Whites with a view of producing a superior 
type. 
424. Chester White compared with Poland China. — The for- 
mer is larger than the latter and can always be distinguished by 
the color. The head of the Chester White is of medium length, 
and the face straight; the ears are large and drooping; the body 
lacks the width and depth of the Poland China, but the back is 
straighter. Common with all white swine, the skin is subject to 
sunscald and scurfiness, especially when exposed to a hot sun and 
dry weather. In quality of meat the Chester White ranks in- 
termediate between the Poland China and the Berkshire (Fig. 109). 
425. Hampshire lard-hog.— This breed, formerly known as 
Thin Rind, was developed in America. The name was changed 
to Hampshire by order of the American Thin Rind Association, 
in 1904. The American history of this breed traces back through 
Fira. 110.— The Hampshire. Lard type. 
Canada and Massachusetts to Hampshire and Essex, England. 
About 1820 to 1825, MacKay imported Thin Rinds from Hamp- 
shire, England, to Boston, Massachusetts. Later, these hogs found 
their way to Kentucky. Some of these animals were taken to 
the central states, where the breed has been greatly improved by 
careful selection.
