Frye-Bruhn rule

Frye-Bruhn rule

One of several formulas for estimating the volume of haystacks. It was used chiefly in the Pacific Northwest. Measure the distance from the ground on one side of the stack to the top of the stack, over it, and down to the ground on the other side, and then subtract the stack width. Multiply that number by one-half the stack width times the full stack length to get the volume of the stack in cubic feet. This rule is reasonably accurate when the stack height is about the same as the width. For other formulae, see the Fowl rule, the Outlaw rule, and the Quartermaster’s rule.
