434 THE BREEDS OF LIVE-STOCK 



judge from experimental work and from practical experi- 

 ence. The Chester-White is also a good grazer, and in 

 this feature probably excels the Yorkshire and the Tarn- 

 worth, which are better adapted to pen feeding. 



It is said that the Chester- White, as a breed, is some- 

 what more prolific than the Poland-China and the fine 

 type of Berkshire. The assertion is supported by the 

 findings of A. W. Bitting, who investigated the matter 

 in 1897. 



For crossing purposes, the Chester-White is highly 

 esteemed, a cross with the Poland-China being regarded 

 with especial favor by feeders. The grade Chester-White 

 sow is a very useful farmer's pig, and pure-bred boars are 

 very effective in improving common stock. 



528. Distribution. The Chester-White is largely dis- 

 tributed over the United States. It is very popular in 

 the eastern states, and is strongly represented in Ohio, 

 Indiana, Illinois, Iowa, Michigan, Wisconsin, Pennsylvania 

 and other states. It has also spread to the South, to 

 some extent at least, and seems to be giving satisfaction. 

 For some reason it has gained a much stronger foothold 

 in Canada than the Poland-China, probably because it 

 seems more easily bred to a lengthy type than the Poland- 

 China. 



529. Organizations and records. The American 

 Chester- White Record Association took over the business 

 of the Chester-White Record Association in 1894. The 

 Chester- White Record Association was organized in 1884, 

 to support Todd's Improved Chester- White Swine, and 

 issued four volumes previous to 1894, when it was changed 

 to the American Chester- White Record. The Ohio Im- 

 proved Chester-White Swine Breeders' Association was 

 organized in 1897. For registration in the herd-book of
