The first-named (Station du Port) came to light only in the beginning of 1884, when the little harbour at the town of Annecy was being deepened to facilitate the movements of the pleasure-steamers which ply on the lake during the season. In the course of these operations the dredging-machines came into contact with piles, and brought up various kinds of stone implements, etc., in the mud, which, unfortunately, were mostly re-deposited in deep water. The spot where these remains were found lies just at the extremity of the Swan Island; and after the public works were completed, the dredger was put at the disposal of the Société Florimontane, who conducted systematic investigations, both there and at the stations of Roselet and Vieugy. Previous to this time all the stations examined had yielded more or fewer bronze objects, and they were therefore considered to be analogous to those of Lake Bourget, all of which were founded during the Bronze Age. The explorations conducted at the Station du Port upset this view, as from the character of the relics found on it there could be no doubt that its inhabitants lived chiefly during the Stone Age, but the station survived to the Bronze Age. The objects collected from it consist of perforated hammer-axes of serpentine (=Fig. 22=, Nos. 8 and 9), polished hatchets of serpentine, stone spindle-whorls, beautifully-worked daggers and lance-heads of flint (Nos. 5, 6, and 7), as well as arrow-heads, (one of shale stone No. 10), saws, scrapers, etc., of the same material. Only two metal objects, viz. a bronze hair-pin (No. 2), and a bead (No. 3), probably of copper, like those from Vinelz are recorded; but these are said to have been on the surface of the relic-bed. STATION DU ROSELET was the first discovered in this lake, but it has yielded only a few relics, among which are fragments of pottery, some fine spindle-whorls, a hatchet of serpentine, and a bronze bracelet. CHATILLON was in a depth of 8 to 13 feet, and among its relics are a socketed knife and a couple of bracelets (No. 4). The settlement at Vieugy was discovered in 1868, and the most important objects from it are a bronze hatchet of the flat type (No. 1), some stone moulds, and a few rubbers. (B. 315.) LAKES OF AIGUEBELLETTE AND THUILLE. M. Troyon reported the existence of piles at two places in the Lake Aiguebellette, and one in Lake Thuille; but of these I find no further records. (B. 31.) LAKE CLAIRVAUX (FRANCE). The Lake of Clairvaux is situated on the first rising plateau of the Jura mountains, not far from the town of Lons-le-Saulnier, and covers an area of about 200 acres. At its north-west extremity there is a tongue of land projecting into the lake called La Motte-aux-Magnins, which is believed to have been an island in former times, but is now continuous with a tract of marshy ground which extends between the Motte and the town of Clairvaux.
