Milk, Water of, a rivulet of Annandale, Dumfriesshire, rising in Westerkirk parish, at an altitude of 780 feet, and winding 17¾ miles south-south-westward, chiefly along the boundary between Tundergarth on the left, and Hutton, Dryfesdale, and St Mungo on the right, till, after a total descent of 640 feet, it falls into the Annan near Hoddam Castle, 3¾ miles WSW of Ecclefechan. It is fed by Corrie Water and a score of lesser burns; in its upper reaches traverses an upland vale, abounding in picturesque close scenes; and in its lower ones shares largely in the mild and gentle beauties of the Howe of Annandale.—Ord. Sur., sh. 10, 1864.
