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.
It has been recorded that at various times prior to 1870 diverse antiquities were found in the course of drainage operations in this marshy ground, such as horn implements, stone axes of flint and jade, boars' tusks, bits of pottery, bronze celts, a fibula, and an armilla; also Gallo-Roman remains, including a Gaulish gold coin and Roman coins. In the lake itself there were no discoveries made, with the exception of a group of five piles known to fishermen. But none of these discoveries had ever suggested to any one the idea of a lake-dwelling, the common and accepted opinion being that they were remains of Druidical times and customs.
On the 27th of June, 1870, when the water was about its lowest, Mr. Le Mire happened to be walking on the shore and accidentally stumbled on the top of a black pile of oak. His attention being thus directed to such a curious object, he looked about and detected many others just protruding from the lake-bottom. He then determined to investigate the matter, and at once employed some labourers to make excavations. The place selected was 100 yards to the west of the Motte-aux-Magnins, and 25 yards to the east of the canal which forms the outlet of the lake. Trenches were dug about 1 yard in width and the same in depth (a greater depth being prevented by the oozing up of water). During these operations piles were abundantly met with, but no relics were found, and it was remarked that there was no change in the stuff thrown up from the trenches, it being the ordinary whitish deposits similar to what is seen on the present surface of the strand. The piles were of oak, fir, yew, poplar, willow, and hazel, and measured from 4 to 6 inches in diameter.
