It has been well pointed out by Fergusson, in his “Rude Stone Monuments,” that the megalithic architecture of the remote past is a thing altogether apart; its special form indicating now the tendencies of a race or group of races of mankind, now the particular degree of civilization attained by a race at a certain period of its development. A cursory view of these monuments as a whole would lead us to class them all together as masses of rough, scarcely hewn stones piled up without cement, and almost always without ornamentation. In studying them one by one, however, we find, in spite of their undeniable family likeness, if we may use such a term, that it is quite easy to snake out certain differences, the result of the peculiar genius of the race by whom they were erected, or of the nature of the materials the builders had at their disposal. To take a case in point: Cromlechs are most numerous in England, and dolmens in France, and in both these countries we meet with a form of dolmen (Fig. 66) such as is rarely set up in other districts; one of the extremities of the table resting on the ground, and the other opt two supporting stones. In Scandinavia the supports are erratic blocks, in India fragments of the rocks in the neighborhood, in Algeria and the south of France buildings in courses are often met with; in Brittany the monuments of Mané-er-H’roek and Mané-Lud are paved with large stones. The ground from which rises the dolmen of Caranda, near Fère in Tardenois (Aisne), is covered with slabs, and the opening is closed with a flat stone resting on two lintels. We cannot speak of Caranda without referring to the discoveries and magnificent publications of M. F. Moreau, thanks to whom the daily life of the Gauls, Gallo-Romans, and Merovingians is brought vividly before us. To return, however to our monuments: As we have seen, the crypt was in many cases divided into two or more sepulchral chambers by walls made of stones. We find this arrangement at Gavr’innis, at Gamat (Lot), at Alt-Sammit in Mecklenburg, in Wayland Smith’s cave in Berkshire, and in a great many monuments in Scandinavia. M. du Chatellier speaks of several megalithic monuments in Finistère, including a central dolmen and several lateral chambers. The chambered graves at Park Cwn in Wales, and at Uley in Gloucestershire, contain side chambers, those of the former with a covered passage between them, whilst in the latter the side chambers are grouped round a central apartment. At New Grange, in Ireland, a passage more than ninety-two feet long leads to a double chamber of cruciform shape, with a roof of converging stones. Yet another fine example of a similar kind is that of Maeshow in the Orkney Islands. The tomb of Vauréal (Seine-et-Oise) contains three crypts of different sizes. The long barrow of Moustoir-Carnac contained four separate chambers, the western one of which is a dolmen of the kind known as _Grottes des Fées_, and
