part of the northern dolmen region; but the following, which is abstracted from Bonstetten's 'Essai sur les Dolmens,' may convey some general information on the subject, especially when combined with the map (p. 275), which is taken, with very slight modifications, from that which accompanied his work.
According to Bonstetten there are no dolmens in Poland, nor in Posen. They first appear on the Pregel, near Königsberg; but are very rare in Prussia, only two others being known, one at Marienwerder, the other at Konitz. In Silesia there is one at Klein-Raden, near Oppeln; another is found in the district of Liegnitz, and they are very numerous in the Uckermark, Altmark, in Anhalt, and Prussian Saxony, as well as in Pomerania and the island of Rügen. They are still more numerous in Mecklenburg, which is described as peculiarly rich in monuments of this class. Hanover possesses numerous dolmens, except in the south-eastern districts, such as Göttingen, Oberharz, and Hildesheim. To make up for this, however, in the northern districts, Lüneburg, Osnabrück, and Stade, at least two hundred are found. The grand-duchy of Oldenburg contains some of the largest dolmens in Germany; one of these, near Wildesheim, is 23 feet long; another, near Engelmanns-Becke, is surrounded by an enclosure of stones measuring 37 feet by 23, each stone being 10 feet in height, while the cap stone of a third is 20 feet by 10. In Brunswick there were several near Helmstädt, but they are now destroyed. In Saxony some rare examples are found as far south as the Erzgebirge, and two were recently destroyed in the environs of Dresden. Keeping along the northern line, we find them in the three northern provinces of Holland, Groningen, Ober-Yssel, and especially in Drenthe, where they exist in great numbers, but none to the southward of these provinces, and nowhere do they seem to touch the Rhine or its bordering lands; but a few are found in the grand-duchy of Luxembourg as in a sort of oasis, halfway between the southern or French dolmen region and that of northern Germany.
From the North German districts they extend through Holstein and Schleswig into Jutland and the Danish isles, but are most numerous on the eastern or Baltic side of the Cimbrian peninsula, and they are also very frequent in the south of Sweden and the adjacent islands. Dolmens properly so called are not known in
