Typically split from Cedar logs (or Chestnut until the blight decimated them) the zig-zagg split-rail fence is a sign of both abundant timber and land.  Except for the tools needed in the splitting, these fences do not require much else.  The pattern supports itself without fasteners like nails or bolts or wire – although when available these may be used for reinforcement.   I remember when country hikes might come upon such comely barriers.   Zig-zag fences may also be easily moved, and in a fuel emergency cut up for firewood.
