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 Tam- 
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, lowa, 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
