“Procure pickets two inches wide, by half an inch thick, and six feet long; nail them to two rails, three inches square and twelve feet long; at each end of every rail, U-shaped pieces of stout hoop-iron (hogshead iron is best) are fastened by screws, so as to form staples, through which posts seven feet long and two and a half inches in diameter, pointed at both ends, are thrust and set firmly in the ground.” — Harcourt, 1889
