As eldren men has made record.
Your headroom to the hill direct,
Frae your haugh tilled in effect.
Betwixt twa glenis ane montis borde,
Divides thae glenis, I sall stand for’t.
Water comand frae ane glen head,
Divides that glen, and stanches feid.
Thortrom[151] burnis in montis hie
Sall stop nae headroom, though they be.
The meaning of all this is, that ancient custom in Scotland recognised three natural divisions or boundaries for land—1. Headroom, the termination of a piece of territory on the summit of the slope of the adjacent hill; 2. The line of hills between two glens; 3. The river passing through a glen. A water crossing the headroom on the summit of the mountains made no difference.[152]
