Tweed
Tweed, a river of Scotland, which flows in a N.E. direction through Southern and Central Peeblesshire, then, turning E., traverses the N. portion of Selkirkshire and Roxburghshire, and, finally, resuming its N.E. course, for 18 miles forms the boundary between Berwickshire and Northumberland, thus separating the sister-kingdoms. Its length in all is 97 miles. The salmon-fisheries attract anglers, but the river has larger claims on all lovers of beautiful scenery. It also figures largely in the legendary lore and ballad literature of the border, and its name is inseparably associated with that of Sir Walter Scott.
