The dry stone walls in the area of Glenn Lyon Scotland that Norman has done a lot of work have metal fencing along the top of them. Earlier this month we were happing near Bridge of Balgie. The wire fencing has been added to increase the height of the wall so that the sheep wont be able to get over. The two strands of wire are held by metal posts imbedded into large cope stones at intervals of about 16 feet. The wires run through the posts but are not fastened at the post. When a section of wall has slumped and needs repairing the individual cope stones with posts can be easily lifted and slid along the wire and repositioned temporarily on another section of wall until the repair is done. Then the cope stone is lifted back into position.
