“ The present day pigs are shorter and deeper in the carcass; they have shorter and heavier heads, and are altogether more compactly built; to such a state of this kind of perfection have the breeders brought their pigs, that a well-fattened Berkshire is one of the most successful fat show pigs of the day. A cross between the Berkshires and the Middle Whites is very common and very successful for breeding London porket pigs; the white pig is considered to be more prolific, and the cross-bred pigs grow faster when young than the pure bred Berkshires. ”
