THE CHESTER WHITE BREED 67 
Chester White, can hardly be regarded as a distinct strain of 
the breed at present. At one time it had a herd record of its 
own, but in 1894 the articles of incorporation were changed 
to read .\merican Chester White Record Association. Briefly, 
the history of the so-called Improved Chester White is as 
follows: About 1827, Norfolk Thin Rind pigs were imported 
from England to Connecticut. Two brothers, named Todd, 
bought a boar of this breed and a sow of what was called the 
Grass breed, and took them to Ohio, where they were bred 
together with considerable success. Later, one Joseph Haskins 
brought to Ohio a boar of the Byfield breed and a sow similar 
to the original Todd sow. The Todd and Haskins pigs were 
bred together, and Isaac Todd also used other boars in his 
herd, among which was one said to be of the Grass breed, and 
another one ealled a Normandy boar, though little is known 
of the breeding of either of them. Both these boars were white 
in color. In 1865, Isaac Todd introduced Chester White blood, 
and his son, 8. H. Todd, made further use of the Chester 
White, evolving, by careful breeding and selection, what came 
to be known as Todd’s Improved Chester White. 
3. Lhe Ohio Improved Chester White, commonly known as 
the O.I.C. strain, is the product of the efforts of L. B. Silver 
of Ohio, who, in 1865, commenced breeding Chester Whites, 
and who aimed to produce a superior type through selection. 
This branch of the breed has an association and herd record 
of its own, but it would require a person more than ordinarily 
expert to distinguish animals of this strain from other Chester 
Whites, as they appear at the various exhibitions. 
Distribution.—The Chester White is widely distributed in 
the United States. It is popular in the East, and is strongly 
represented in Ohio, Illinois, Indiana, Iowa, Michigan, Wis- 
consin, Pennsylvania, and other states. It has also spread to
