Among the antiquities which some of our English villages possess, none are more curious and remarkable than the grand megalithic monuments of the ancient races which peopled our island. Marvellous memorials are these of their skill and labour. How did they contrive to erect such mighty monuments? How did they move such huge masses of stone? How did they raise with the very slender appliances at their disposal such gigantic stones? For what purpose did they erect them? The solution of these and many such-like problems we can only guess, and no one has as yet been bold enough to answer all the interesting questions which these rude stone monuments raise. Superstition has attempted to account for their existence. Just as the flint arrow-heads are supposed by the vulgar to be darts shot by fairies or witches which cause sickness and death in cattle and men, and are worn as amulets to ward off disease; just as the stone axes of early man are regarded as thunder bolts, and when boiled are esteemed as a sure cure for rheumatism, or a useful cattle medicine--so these stones are said to be the work of the devil. A friend tells me that in his childhood his nurse used to frighten him by saying that the devil lurked in a dolmen which stands near his father's house in Oxfordshire; and many weird traditions cluster round these old monuments. [Illustration: MENHIR] In addition to the subterranean sepulchral chambers and cairns which we have already examined, there are four classes of megalithic structures. The first consists of single stones, called in Wales, Cornwall, and Brittany, _menhirs_, a name derived from the Celtic word _maen_ or _men_ signifying a stone, and _hir_ meaning tall. In England they are known as "hoar-stones," _hoar_ meaning a boundary, inasmuch as they are frequently used in later times to mark the boundary of an estate, parish, or manor. There is one at Enstone, Oxfordshire, and at Wardington, Warwickshire. Possibly they were intended to mark the graves of deceased chieftains. The second class consists of lines of stones, which the French call _alignements_. Frequently they occur in groups of lines from two to fourteen in number, Carnac, in Brittany, possesses the best specimen in Europe of this curious arrangement of giant stones.
