TWEEDSMUIR, a parish in the south-western extremity of Peebles-shire. It has on its northern margin the post-office station of Crook-Inn. It is bounded by the counties of Dumfries and Lanark, and by the parishes of Drummelzier and Megget. It is not very far from being a regular circle of about 8¼ miles in diameter. The surface is a congeries of mountainous hills, with narrow intervening flats and morasses. The hills, in general, are luxuriant in verdure on the sides, and often boggy on the tops; affording on the former, rich supplies of pasture and even crops of hay, and, on the latter, a large proportion of the local supply of fuel. They are broad-based, slow of ascent, soft in outline, and summited with table-land. Horses can easily ascend them, and, even without difficulty, bring down loads of turf. The highest elevations are Broadlaw on the north and the culminating point of Hartfell on the south. See the articles BROADLAW and HARTFELL. The predominant rocks are greywacke and greywacke slate. The soil in many places is a strong thick mould, formed of earth and moss; and that of the arable parts is generally a light loam, incumbent on gravel and sandstone. The river Tweed originates and has its first 10 miles' run in the parish; and, in return, gives its name as the prenomen of that of both the district itself and several of its localities. No fewer than about twenty-five indigenous and independent streamlets fall into it before it departs, and render it, even in this lofty land of its infancy, not altogether unimportant in volume. The chief of these streamlets are the Core, the Fruid, the Menzion, the Tala, and the Harestone. Gameshope-loch, about 600 feet in diameter, is probably the loftiest lochlet in the south of Scotland, and abounds in excellent dark-coloured trout. A peculiarly fine perennial spring, called Geddes'-well, sends out a rill near the summit of Broadlaw. The parish is as eminently pastoral in the richness of its herbage, and the prime quality of its flocks, as in the mountainousness of its physical features. About 16,000 sheep are pastured; more than three-fourths of them Cheviots, the rest black-faced. Only about 280 acres are in tillage; though, but for the distance and expense of lime and other appliances, a large aggregate extent of the lower declivities of the hills might easily be subjected to the plough.
