Treading barn | Article about treading barn by The Free Dictionary
A circular two-story barn once specifically constructed for threshing grain. Horses or oxen were led around the second story of the barn, across layers of wheat; the grinding action of their hooves separates the wheat from the chaff; the grain fell through gaps between the floorboards into the granary in the story below.
