DEVELOPMENT OP THE BREEDS 87 



twin brother of the original Mr. Todd, crossed these hogs 

 on the original Chester Whites from Chester County, 

 Pennsylvania, using six or seven crosses. This produced 

 what is known as Todd's Improved Chester. It was an 

 excellent white hog of very uniform type. The name 

 Todd was later dropped and only the term Improved

After having established and developed his herd they 

 were called the Ohio Improved Chesters (O. I. C). They 

 were said at the time to be a better hog than the original 

 Chester White, havmg more quality, more uniformity, 

 and better form. During recent years, however, whatever
