David I. Davis, The modern packing house (1903)
“ Description of Beef Casings. —Casing is a product made from the intestines of cattle, sheep and hogs. They are saved when animals are slaughtered in quantities sufficiently large to warrant the care and attention required. This was one of the products which was wasted where animals were slaughtered on a small scale. It is a product worthy of careful attention to its production in order that it be in a good, marketable condition.Casings consist of round or small guts, middle or large intestines, bungs, weasands and bladders, these being the names of casings obtained from cattle. ”
