CHAPTER XI.
GRINDING-STONES AND WHETSTONES.
Before proceeding to the consideration of other forms of implements, it will be well to say a few words with regard to those which have served for grinding, polishing, or sharpening tools and weapons, and more especially such as there is every reason to suppose, were employed to give an edge or finish to other materials than metal, though the whetstones of the Bronze Period must not be passed by unnoticed.
I have already mentioned the fact that the grindstones on which stone celts and axes were polished and sharpened, were not like those of the present day, revolving discs against the periphery of which the object to be ground was held; but stationary slabs on which the implements to be polished or sharpened were rubbed. Considering the numbers of polished implements that have been discovered in this country, it appears not a little remarkable that such slabs have not been more frequently noticed, though not improbably they have, from their simple character, for the most part escaped observation; and even if found, there is usually little, unless the circumstances of the discovery are peculiar, to connect them with any particular stage of civilization or period of antiquity. In Denmark and Sweden, however, these grinding-stones, both of the flat and polygonal forms already described, are of comparatively frequent occurrence. Specimens are figured by Worsaae,[1] Sophus Müller, and others, and were also given by Thomsen,[2] so long ago as 1832. He states that they have been found in Scandinavia, in barrows and elsewhere in the ground, with half-finished stone celts lying with them, so that there can be no doubt as to the purpose for which they were intended. They are also described by Nilsson[3] and Montelius.[4]
