THE DUROC-JERSEY 719 



in 1893, since which time a total of sixty-two volumes have 

 been issued to 1919, including the registration of over 500,000 

 boars and sows. The letter " a " after the registration number of a 

 Duroc-Jersey pig indicates its registration in the American Associ- 

 ation and an " n," in the National Association. Each of these organi- 

 zations has been very prosperous. In addition to these associations 

 for promoting the purity of the breed and the registration of 

 animals, there have been organized a number of state and local 

 associations for the same purpose. In general, it may be stated 

 that the organized interests in behalf of the Duroc-Jersey are strong 

 and have accomplished much important publicity and breed-welfare 

 work. The Duroc Bulletin, a semimonthly in behalf of the breed, 

 published in Chicago, and the Duroc Digest, published in Minne- 

 apolis, are valuable mediums for circulation among the breeders, 

 as they contain a large amount of Duroc-Jersey literature and 

 advertising matter of importance.
