This class of sepulchral monuments is rare in Scotland when compared with other monolithic structures that abound in almost every district of the country. Some few interesting examples, however, are still found perfect, while partial traces of a greater number remain to show that the cromlech was familiar to the builders of the Scottish monolithic era. One of the most celebrated Scottish cromlechs is a group styled, THE AULD WIVES' LIFT, near Craigmadden Castle, Stirlingshire. It is remarkable as an example of a trilith, or complete cromlech, consisting only of three stones. Two of nearly equal length support the huge capstone, a block of basalt measuring fully eighteen feet in length, by eleven in breadth, and seven in depth. A narrow triangular space remains open between the three stones, and through this every stranger is required to pass on first visiting the spot, if, according to the rustic creed, he would escape the calamity of dying childless. It is not unworthy of being noted, that though the site of this singular cromlech is at no great elevation, a spectator standing on it can see across the island from sea to sea; and may almost at the same moment observe the smoke from a steamer entering the Frith of Clyde, and from another below Grangemouth, in the Forth. [Illustration] From the traces of ruined cromlechs which are still visible in various parts of the country, some of them appear to have been encircled, like a class of barrows described above, with a ring of standing stones; and it is exceedingly probable that many of the smaller groups throughout the country, designated temples, or Druidical circles, belong to the class of sepulchral memorials. Such is the case with a monolithic group in the parish of Sandwick, Orkney, and it is still more noticeable in the ring of Stennis, where the cromlech lies overthrown beside the gigantic ruins of the circle which once inclosed it. Various other cromlechs still remain in Orkney. One called the Stones of Vea, situated on the moor about half a mile south of the manse of Sandwick, though overthrown, is otherwise uninjured. The capstone measures five feet ten inches, by four feet nine inches, and still rests against two of its supporters. A group, which stands on the brow of Vestrafiold, appears to have included two if not three cromlechs. There is another remarkable assemblage, in a similarly ruined state, near Lamlash Bay, in the island of Arran; and a single cromlech stood--if it does not still stand--in the centre of a stone circle in the same island.[79] A fine one also remains, in perfect preservation, on the southern declivity of the hill of Sidla, Forfarshire; another good example has been preserved on the farm of Ardnadam, in the parish of Dunoon, Argyleshire; and others, more or less complete, are to be seen at Achnacreebeg, Ardchattan, and in various districts of the West Highlands, as well as in other parts of Scotland.
