[Illustration: RUINS OF WARK CASTLE.] As the stream is traced upwards, the banks not seldom break into cliffs, the valley gains in breadth and richness, and away to the north the sky-line is broken by the round top of Dunse Law. Nearly midway between Coldstream and Kelso the Tweed ceases to be the Border river, and enters the shire of Roxburgh, and a little higher up it takes toll of the "troutful Eden," which on its way down from the slopes of Boon Hill has watered the village of Ednam (Edenham), where "the sweet poet of the year" was born. A couple of miles or so away to the south is Hadden Rig, scene of the fight between the English and Scottish Marchwardens in 1542. Sir Robert Bowes, Governor of Norham, had, with three thousand horse, ravaged a large part of Teviotdale, and was marching on Jedburgh, when he encountered George Gordon, Earl of Huntly, and, with several of his colleagues and many of his men, was taken prisoner. Fighting on the English side was the exiled Earl of Angus, who only by a desperate exercise of strength and activity escaped capture and the traitor's doom which would inevitably have followed.
