Anotations

Scope note:

Buildings built after the early 19th century, not found only on farms, for the mechanized processing, storing, or selling of milk and milk products. Distinguished from "dairies (non-mechanized)" by the use of mechanization. For subsidiary agricultural buildings devoted primarily to the care of milk, often with little or no mechanization, prefer "milk houses."
