6. Clapper stile
The last word in ingenious craftsmanship. A length of timber fencerails is loosely held horizontal by a weight attached to one end of each. The other end is unattached, finishing just shy of the adjacent post. These rails can be readily pushed down at the unattached end, enabling the walker to step over them. When the hand is released, the rails spring back up to their earlier position. A little mental preparation is called for, otherwise the rails will spring back up when the walker is halfway across, leaving gentlemen somewhat compromised. Their companions will, I’m sure, sympathise.
