La glissade appears rarely to have been practised on true megaliths, for the reason that they rarely present the inclination necessary to its accomplishment. It is, however, said at Loc- mariaker, in the Morbihan, that formerly every young girl who wished to marry within the year, on the night of the first of May got on the large menhir, turned up her skirts and let herself slide from top to bottom. The menhir mentioned was the largest one known; but it is now broken in four pieces which lie on the ground; according to most authors it was still standing at the beginning of the eighteenth century. This custom, which could not be followed when the stone stood vertical, twelve meters in height, is, then, relatively modern, yet it is possible that the young girls of the locality have come to follow, on the pieces, an ancient custom which was formerly held on some natural stone in the neighborhood.
