YARROW  , a

river and parish of Selkirkshire, Scotland . The river, issuing from St Mary's Loch, flows for 14 M . E. by N. to the Tweed, which it joins about 3 M. below the county town . The stream and vale are famous in poetry . Only a fragment remains of Dryhope Tower, on Dryhope Burn, the home of Mary Scott, " the flower of Yarrow," whom Walter Scott of Harden married about 1576 . On Douglas Burn, a left-hand tributary, are the ruins of the keep of " the good " Sir James Douglas, the friend of Robert Bruce; and Blackhouse, Mount Benger and the farm of Altrive are all connected with James Hogg . Near Broadmeadows Sir William Douglas, the knight of Liddesdale, was murdered by his kinsman (1353) in revenge for the death of Sir Alexander Ramsay of Dalhousie at Hermitage Castle . The body lay for a night in Lir.-dean church, now in ruins, near Selkirk, before its burial in Melrose Abbey . On the right bank are the ruins of Newark Castle, built by James III. in 1466 as a hunting seat, afterwards the property of the Scotts of Buccleuch . It was burned by the English in 1548, but the tower was restored . On the right side of the Yarrow is Bowhill, a seat of the duke of Buccleuch .
