1805.  Scott, Last Minstr., I. viii.

        While Cessford owns the rule of Carr,
  While Ettrick boasts the line of Scott,
The slaughter’d chiefs, the mortal jar,
The havoc of the feudal war,
  Shall never, never be forgot!
    Ibid., III. iv.
Few were the words, and stern and high,
  That mark’d the foemen’s feudal hate;
For question fierce, and proud reply,
  Gave signal soon of dire debate.
