William Fream and Robert Wallace, 1911 Encyclopædia Britannica, Volume 21… (1911)
“ The Middle White, formed by crossing the large and the small breeds, is not so symmetrical as the parent stocks, and the type is not uniform. The Lincolnshire Curly Coated or Boston pig is a local breed of great size and capacity for producing pork. It is very hardy and prolific, but somewhat coarse in the bone. It has an abundance of long curly hair, a short face and a straight nose, and the ears, not too long and heavy, fall over the face. It crosses well with the Large White, the Large Black and the Berkshire. ”
