Three wires—barbed with at least 36 two-point iron barbs or 26 four-point iron barbs—on each rod of wire, or of four wires (two barbed and two smooth) to be firmly fastened to posts not more than two rods apart with not less than two stays between posts, or with posts more than one rod apart without such stays, the top wire to be 48-54 inches in height.
