It may be taken for granted that these Hunebeds were at one time much more numerous in Drenthe than they now are, but it is a much more difficult point to ascertain whether they extended into the neighbouring provinces or not. One is found in Gröningen, and one in Friesland, and none elsewhere. It may, of course, be that in these more fertile and thickly inhabited districts they have been utilised, or removed as incumbrances from the soil, while in Drenthe their component parts were of no value, and they are useful as sheep-pens and pigstyes; and to these uses they seem to have been freely applied. It may be, also, that there are no granite boulders in the neighbouring provinces, and that they are common in Drenthe. There certainly seem to be none in Guelderland, a country in which we would expect to find monuments of this class, as it is the natural line of connection with the German dolmen region; and unless it is that there were no materials handy for their construction, it is difficult to understand their absence. As these Hunebeds have been open and exposed for centuries at least--if they were not so originally--and have been used by the peasantry for every kind of purpose, it is in vain to expect that anything will now be found in them which can throw much light on their age or use. We can only hope that an untouched or only partially plundered example may be found in some of the numerous tumuli which still exist all over the country. I confess I do not feel sanguine that this will be the case. I would hope more from the digging up of the floor of those which are known, and a careful collection of any fragments of pottery and other objects which may be found in them. Nothing of any intrinsic value will be found, of course; but what is perfectly worthless for any other purpose may be most important in an antiquarian sense. Judging them from a general abstract point of view, they do not seem of high antiquity, and may range from the Christian era down to the time when the people of this country were converted to Christianity, whenever that may have been. This, however, is only inferred from their similarity to other monuments mentioned in the preceding pages, not from any special evidence gathered from themselves or from any local tradition bearing on their antiquity. When we have examined the megalithic remains of Brittany and of the north of France, we shall be in a better position than we now are to appreciate the importance of the gap that exists between the French and Scandinavian provinces; but in the meanwhile it may be convenient to remark even here that it hardly seems doubtful that the Hunebeds of Drenthe and the Grottes des fées of Brittany are expressions of the same feeling, and, generally, that the megalithic remains of the southern and northern divisions of the western parts of the European continent are the works of similar if not identical races, applied to the same uses, and probably are of about the same age.
