Black's Law Dictionary
Lands in Scotland where the ridges of a field belong alternatively to different proprietors. Anciently this kind of possession was advantageous in giving a united interest to tenants to resist inroads. By the act of 1695, c. 23, a division of these lands was authorised, with the exception of lands belonging to corporations.
