a building usually intended to house animals for long periods during the winter season.

barn sheet

a sketchy method of recording events, especially reproductive ones, in the lives of the inmates of the barn. Fixed to the barn wall it does provide an opportunity to record events as they happen, but suffers the obvious disadvantage of exposure to disfiguring and obscuring materials, especially fly droppings and cow manure. Its design, aimed at encouraging maximum data storage in minimal space, is a test for farmer ingenuity. Called also shed sheet.
