HURDLES

Hurdles are frames formed of perpendicular stakes with horizontal bars, and braced with diagonal pieces for the purpose of forming temporary fences. In fortification the name was given to a collection of twigs or sticks closely interwoven and sustained by long stakes, serving to render works firm, or to cover traverses and lodgements for the defence of workmen against fireworks or stones.
