no doubt exist, but modern antiquaries have not favoured us with any drawings of them. From the diagram and description it will be perceived that in so far as the mound itself is concerned these Danish tumuli are identical with those already quoted as existing in Auvergne (woodcut No. 8), but so far as I know, the square enclosure does not exist in France, nor does it in this country. These square enclosures seem, however, to belong to a very modern date, and the stones, consequently, are small, and may therefore have been removed, which could easily be done; but still there seems little doubt that many of them may still remain, and could be found if looked for.
One of the most striking examples I know of, an oblong rectangular enclosure, enclosing a single free-standing dolmen, is that near Lüneburg, figured by Bonstetten[1] (woodcut No. 110); he seldom, however, indulges in dimensions, and being perfectly convinced that all are prehistoric, he never speculates as to dates, nor condescends to notice traditions. What we know of it is therefore confined to the representation, which after all may be taken from some other work, as he rarely favours us with references. Two others are represented by von Estorff as existing near Uelzen, in Hanover.[2]
A good example of two dolmens in a rectangular enclosure is that at Valdbygaards, near Soröe, in Zeeland. Here the enclosure is about 70 feet in one direction by 20 feet in the other—outside measurement. In this instance, the enclosing stones are smaller in proportion to the dolmens than is usually the case. On the same plate, Madsen represents a single dolmen in a much squarer enclosure.[3] It, like that at Halskov (woodcut No. 107), is represented as standing on a knoll, but whether dolmens stand so
