Five specimens of the same character, of different sizes, the longest about 9 1∕2 inches in length, and the shortest about 4 inches, are said to have been found with Roman remains at Kästrich, near Gonsenheim,[363] and are preserved in the museum at Mainz. The smallest is of greenstone, and the others of chloritic albite. They are said to have been buried in a sort of leather case, arranged alternately with the pointed and broad ends downwards, and in accordance with their size. Eight specimens from museums at Weimar, Rudolstadt, and Leipzig were exhibited at Berlin.[364] in 1880. One from Wesseling,[365] on the Rhine (8 inches), is thought to have been associated with Roman remains. Both with the English and Continental specimens, there appears to be considerable doubt as to the exact localities whence the materials were derived from which these celts are formed. Instruments for which such beautiful and intractable materials were selected, can hardly have been in common use; but we have not sufficient ground for arriving at any trustworthy conclusion as to the purpose for which they were intended. I have, however, a short celt, 3 1∕2 inches long, from Burwell Fen, and made of this jade-like material, which has evidently been much in use, and was once considerably longer. It appears, indeed, to be the butt-end of an instrument like Fig. 52. A detailed account of the jade and jadeite celts in the British Museum is given in the _Zeitschrift für Ethnologie_.[366] |110| It was formerly supposed that the jade of which many hatchets found in Switzerland and other European countries are made, came of necessity from the East, and theories as to the early migrations of mankind have been based upon this supposition. As a fact, jade has now been found in Europe, and notably in Styria[367] and Silesia.[368] Below[369] are given some references to comments on the sources of jade. An account of the method of working jade in Western Yun-nan is given in Anderson’s Report[370] on the Expedition to that country; and a complete and well-illustrated catalogue of objects in jade and nephrite, by Dr. A. B. Meyer, forms part of the publications of the Royal Ethnographical Museum, at Dresden, for 1883. * * * * * I now come to the second of the subdivisions under which I have arranged this class of implements, viz., those having the sides flattened. The flat sides, of course, taper away to a point at the cutting edge of the celts, and usually diminish much in width toward the butt-end, which is commonly ground to a semicircular blunted edge. The implements of this kind are generally very symmetrical in form. * * * * *
