420 THE BREEDS OF LIVE-STOCK 
The boars are prepotent, and cross well with almost any other 
breed, as well as being useful for improving common stock. 
507. Distribution. — Berkshires are found in every 
state and territory of the United States, the most im- 
portant centers being Pennsylvania, Illinois, Missouri, 
Indiana, Texas, Ohio, Kansas, Iowa, New York, Michigan 
and Tennessee. During the last two years more Berk- 
shires were sold into Pennsylvania than into any other 
state. They also are found in every Canadian province, 
the province of Ontario taking the lead. They are found 
in practically all parts of the British Isles, in South 
America, in Hawaii and in some European countries. 
508. Organizations and records. — The American Berk- 
shire Association was organized in 1875, and has the dis- 
tinction of having started the first record of swine in 
America. The first herd-book was published in 1877, and 
up to the present forty-seven volumes have been issued, 
coutaining the names of nearly 208,000 animals. 
Registration of Berkshires in Canada was begun in 
1876, and was conducted by the Agriculture and Arts 
Association until 1891, when the records were taken over 
by the newly organized Dominion Swine Breeders’ Asso- 
ciation. The first volume of the Dominion Swine Breeders’ 
Record was published in 1892. This record recorded all 
breeds of swine represented in Canada. In 1905, the 
Dominion Swine Records, together with nearly all the 
live-stock records in Canada, were placed under the direct 
supervision of the Canadian Department of Agriculture 
at Ottawa, but are under the control of a ‘‘ Record Board,” 
comprised of representatives elected by the various breed 
organizations. This National Live-Stock Record records 
all breeds of swine in Canada, but the herd-book still keeps 
the name of Dominion Swine Breeders’ Record.
