423. Chester White lard-hog.— There are three strains of 
Chester Whites, each with a somewhat different origin. 
(1) The original Chester White. —This strain first became prom- 
inent in Chester County, Pennsylvania, where white hogs have 
existed for many years. They were, perhaps, introduced by the 
earliest settlers. Captain James Jeffries, who in 1818 imported 
a pair of white pigs from England, is commonly spoken of as the 
founder of the strain. Later, Harvy Atwood introduced Chinese 
Fic. 109. —The Chester White. Lard type. 
stock from England to Delaware County. The stock from the 
Jeffries and Atwood herds were blended together, along with the 
common swine, which resulted in the original Chester White 
strain. 
(2) Todd’s Improved Chester White. — This strain was developed 
in Connecticut and Ohio. The Todd Brothers of Connecticut 
purchased a black and white boar imported from England in 1827, 
and known as Norfolk Thin Rind. This boar was mated with 
a white sow of undoubted Irish Gragier blood. Jn 1830, the Todd 
Brothers moved to Ohio, taking with them these two hogs, which 
served as foundation stock. S. H. Todd, a son of one of the Todd 
Brothers, was allied with the improvement of this strain for over 
forty years.
