The term MILKER'S NEED is composed of two words, PAIL and STOOL. A PAIL is a cylindrical container with a handle, usually made of metal, plastic, or wood, used for carrying liquids or other materials. A STOOL is a type of chair without a back or armrests, typically used in milking parlors. Together, these two items are necessary for a milker to do their job, as the PAIL is used to collect the milk and the STOOL provides a place to sit while milking.
