The annexed attempted restoration of one near Emmen will give a fair idea of their general arrangements. It is 49 feet long over all, and internally from 4 to 6 feet in width. It is roofed with nine or ten stones, some of considerable dimensions. Some of these Hunebeds have a range of stones round them, not arranged in a circle or oval form, but, as in this instance, following the lines of the central chamber. This is the case with another near the same place, which is 125 feet in length over all. When closely examined, however, it does not seem to be one Hunebed, but three ranging in a straight line, with a small space between each. Two have five and one six cap stones. As a rule, each cap stone stands on two uprights, and though frequently they touch one another, as often they form really independent trilithons. It was no doubt this fact that induced Keysler to compare these monuments with Stonehenge, though in fact no two sets of rude-stone monuments could well be more dissimilar either in arrangement or construction. As will be seen from the annexed view of one near Ballo[376] (woodcut No. 121), they are formed of unshaped granite boulders. Sometimes, it may be, artificially split, but certainly untouched by the chisel. All that has apparently been done has been to select those most appropriate in form for the purposes to which they were to be applied, and then rudely to heap them one upon the other, but in such a manner as to leave wide gaps everywhere between the stones composing the structure. [Illustration: 121. Dolmen at Ballo. From a Photograph.] * * * * * The first question that arises with regard to these Hunebeds is, were they originally covered with earth or not? That some of the smaller ones were and are is clear enough, and some of medium size are still partially so; but the largest, and many of the smaller, do not show a vestige of any such covering; and it seems impossible to believe that on a tract of wretched barren heath, where the fee-simple of the land is not now worth ten shillings an acre, any one could, at any time, have taken the trouble to dig down and cart away such enormous mounds as would have been required to cover these monuments. It seems here clearer than almost anywhere else that, even if it had been intended to cover them, that intention, in more than half the cases, was never carried into effect.
