{347}Cademuir, by the way, the hill on Manor's right at its junction with Tweed, is the supposed scene of Arthur's seventh battle against the Pagans. _Cad_ is Welsh for battle,--Gaelic, _cata_, hence _Cad-more_, the "great battle." Professor Veitch hesitates between this site and that of the neighbouring pre-historic hill fort, the Lour, near Dawyck, but thinks the former the more probable. Just below the height of the Lour, till the beginning of the nineteenth century there stood, he says, an almost perfect _cromlech_, consisting of "two or more upright stones, and one flat stone laid across as a roof, all of remarkable size." This _cromlech_ was known in the district as Arthur's Oven. It is humiliating to have to confess that it, the neighbouring old peel tower of Easter Dawyck, the Tower of Posso, and the ancient Kirk of St. Gordian, were all made into road metal, or used as material for building walls or farm buildings, by Sir Walter Scott's father, of all people in the world. One may wonder what were Sir Walter's thoughts when he came to know. A little way up from Manor Valley, and joining Tweed from the northern side, is Lyne Water. It is not possible to pursue all Tweed's tributaries to their source, however full of interest each may be, for their name is legion. But Lyne cannot be passed without note being taken of its little--very little--early seventeenth century Parish Church. And adjoining it are remains of a great Roman camp--Randall's Wa's, i: has been called locally from times long past. Perhaps it was here--at least it was on Lyne Water--that Sir James Douglas captured Randolph before the time came when the latter finally cast in his lot with the Bruce. Farther up, on an eminence at the junction of Lyne and Tartli Waters, stands the massive ivy-clad ruin of Drochil Castle. Built by the Regent Morton in the sixteenth century, Drochil was never completed, and never occupied. Just before the building approached completion, Morton, judged guilty of complicity in the murder of Darnley, was executed, beheaded by "the Maiden"--a sort of Scottish {348}guillotine--on 2nd June, 1581; and the home of a Regent of Scotland, "designed more for a palace than a castle of defence," is now a rum, of use only as a shelter for cattle! [Illustration: 0368] Happrew, on Lyne, is the scene of the defeat "wrought by the lords William de Lalymer, John de Segrave, and Robert de Clifford, upon Simone Fraser and William le Walleys at Hopperowe," in 1304. And on the elevated heathy flat below which Tweed and Lyne meet, there is what is called the Sheriff's Muir, of old a mustering place for Scottish forces during the wars with England.
