stack
nounA large conical pile of hay, grain or straw, sometimes covered with thatch. In America, the stack differs from the cock only in size, both being conical. A long pile of hay or grain is called a rick. In England, this distinction is not always observed. This word in Great Britain is sometimes applied to a pile of wood containing 108 cubic feet, and also to a pile of poles; but I believe never in America. Against every pillar was a stack of billets above a man’s highth.
