LYNE (THE), a river of Peebles-shire, the next in local importance to the Tweed. It rises in various little head-waters close on the boundary with Edinburghshire; one of them on Weatherlaw, a very brief distance from the sources of the North Esk, and the Water of Leith; another of them on West Cairn-law, the largest of the Pentlands, 1,800 feet high; and several of them draining Cauldstane-slap, a grand mountain-pass, or place of egress, from Tweeddale to the north. The Lyne, recieving in its progress Baddingsgill-burn, West-water, and numerous mountain-rills, runs 5¾ miles south-eastward through Linton, 2 miles southward between Linton on the west and Newlands on the east, and 3¾ in the same direction through Newlands. It is now joined, half-a-mile below Drochil-castle, by Tarth-water, which bears along with it the tributary waters of a branch of the Medwin, on its right bank, runs 4 miles south-eastward between Stobo and Manor on the right, and Newlands, Lyne, and Peebles on the left, and falls into the Tweed 2¾ miles in a straight line above Peebles. Its entire length of course is 15½ miles, or including sinuosities, about 20. The Lyne is a good trouting-stream.
