426 THE BREEDS OF LIVE-STOCK 



The Ohio Poland-China Record was organized in 1877, 

 and up to 1906 had published twenty-seven volumes. 

 The Central Poland-China Association was organized in 

 1880, and published twenty-six volumes of its Record up 

 to 1906. In 1906, the Ohio and Central Associations 

 amalgamated under the name of the National Poland- 

 China Record Company, and since amalgamation thirty- 

 six volumes have been published, which begin where the 

 Ohio herd-books left off. The Ohio Association recorded 

 103,000 head, the Central Association 48,000 head, and 

 since amalgamation, 150,000 head have been recorded in 

 the National. The Standard Poland-China Record Asso- 

 ciation was organized in 1887, and has published thirty- 

 five volumes since that time with over 256,000 registrations. 

 The Northwestern Poland-China Swine Association was or- 

 ganized in 1881. The Southwestern Poland-China Record 

 Association was organized in 1896. These associations 

 in the main are thrifty and influential, as indicated by the 

 large number of registrations; but the best interests of 

 the breed demand greater unity of effort and of ideals. 



In Canada, Poland-Chinas are recorded in the Dominion 

 Swine Breeders' Record.
