" The Scots knew that the burning of a cross was a summons to the clan, and to all the kinsmen of all kindred clans: a summons to rally to the cross for battle. And the burning cross was raised only by the chief of the clan. By ancient law, once raised, the burning cross committed the clan to defend the land unto the end of the clan. "
