bronze age of the lake-dwellings, and the subsequent iron age, so characteristic in La Tène. For the relative positions of these stations see Sketch Map, page 9. LAKE OF BIENNE. INVESTIGATIONS IN THE JURA LAKES, AND ARCHÆOLOGICAL RESULT OF THE "CORRECTION DES EAUX DU JURA."--At a short distance from the eastern shore of Lake Bienne, near where the Zihl by several mouths found its former exit, there exists, or rather formerly existed, a stony elevation, covering an area of some three acres, which rose gradually from a depth of about 20 feet to within 7 or 8 of the surface. This curious cairn-like structure, being in marked contrast with the surrounding lake sediments which here consist chiefly of fine mud, was well-known to the fishermen as the "Steinberg," _i.e._ stone hillock. Among these stones were many projecting heads of piles which, to prevent injury to their nets, the fishermen were in the habit from time to time of pulling out. Moreover, at various times, on or near this steinberg, Roman tiles and some fantastically shaped objects covered with chalky concretions were picked up, which fostered a vague opinion that it was the foundation of a Roman fortress or lighthouse. In 1854 Colonel Schwab and Mr. Müller of Nidau made a careful investigation of the steinberg, the result of which was to leave no doubt that it was the site of a lake-village which had been erected over the piles, the stumps of which then only were detected among the stones. These stones were of a pretty uniform size, not too large to be transported readily by human hands, and in material they were exactly similar to those scattered among the glacial _débris_ on the neighbouring slopes. Interspersed in this cairn were, not only the upright piles of round or split stems, singly and in groups, but also transverse beams, which had evidently not fallen at random but had been intentionally placed and jammed between the uprights to keep them more firmly in position. The strange-looking objects turned out to be bronze implements encrusted with such a coating of lime that their metallic nature had been effectually concealed. The station quickly proved to be exceedingly rich in antiquities of new and varied forms. Not only the usual objects of the Stone Age, but even implements of iron and fragments of pottery of unusual elegance were fished up.
