hook at each end, was dug up in County Antrim in 1808.[145] Monolithic groups abound in many parts of the mainland as well as in the Western Isles, but nearly all characterized by some peculiarity. Some are inclosed by a trench, others by a fosse; and frequently the space between the great stones is filled up by an earthen wall. In several districts in the south of Scotland single and double ovals are found, and fragments of ancient groups, more or less imperfect, are common throughout the country. The woodcut represents an imposing monolithic group in the neighbourhood of Pitlochrie, Perthshire. One of the great level Highland moors stretches away beneath the eye, like a dark waveless lake, contrasting with the distant heights, among which Benlawers rears its pyramidal summit to an elevation of upwards of 4000 feet above the level of the sea. Amid this wild Highland landscape the huge standing stones, grey with the moss of ages, produce a singularly grand and imposing effect; and from the idea of lofty height which the distant mountains suggest, they convey a stronger impression of gigantic proportions than is produced even by the first sight of the giant monoliths of Salisbury Plain. [Illustration: Standing Stones at Pitlochrie.] The most remarkable of the Hebridean groups is that of Classernish, near Loch Roag, in the island of Lewis. It consists of a circle sixty-three feet in diameter, with a column in the centre measuring thirteen feet in height, and an avenue of similar stones stretching to the north, while single rows placed towards the other cardinal points complete the cruciform arrangement of the whole. Its greatest length is stated by Logan as 558 feet, and by Macculloch as about 680 feet; but many of the stones are nearly buried in the moss, so that its extreme limits are very imperfectly defined. It appears to have consisted originally of about seventy columns, and smaller circles in the same neighbourhood attest the ancient presence of a numerous population on the long desolate waste, where the grey columns of Classernish are still imposing in their ruins. The magnitude and singularity of this monolithic group have excited the enthusiasm of Celtic antiquaries, some of whom have discovered in it the very hyperborean temple of the ancients, in which, according to Eratosthenes, Apollo hid his golden arrow![146] But perhaps the most interesting of all the temple groups of the Hebrides, is one which furnishes the same indisputable evidence of remote antiquity to which repeated reference has been made. It may perhaps be thought a more potent weapon even than the hammer of Thor, in demolishing the exclusively Scandinavian theory of their origin. In the same island of Lewis a large stone circle may be seen, which within memory of the present generation was so nearly buried in the moss that the surrounding heather and rushes sufficed to conceal the stones. It has now been cleared out to a depth of fifteen feet, by the
