II. Of the characteristic dolmen, which we in England call cromlech, we have but a single good example, that at Drewsteignton. Cornwall possesses numerous and fine specimens; they abound in Wales and in Ireland. But although we have one only remaining, it can hardly be doubted that formerly there were others, wherever the name of Shillstone (Shelfstone) remains, as near Modbury, and in Bridestowe.

As it became crowded with skeletons, the earliest were unceremoniously thrust back to the rear, to make room for the last comers. The allée couverte in France, and the chambered barrows of Denmark, North Germany, Scotland, Ireland, and England, are but extensions of the dolmen to hold a larger number of the dead. The dolmens usually have a hole at one end, or a footstone that is removable at will, to allow for food to be passed in to the dead, and for the introduction of fresh applicants for house-room in the mansion of the departed.
Some of these holed dolmens have the stone plugs for closing the holes still extant. On Dartmoor in the kistvaens a small stone at foot or side was placed, to be removed at pleasure.

The kistvaen, or stone chest, is a modification of the dolmen, and is usually of a later date; when incineration was become customary, the need for such enormous mortuary chapels, or tombs, as the dolmens and allées couvertes ceased. The dead could be packed into a much smaller space when reduced to
