(7) _Station de Treytel._--This station presents a fine example of the second Stone Age period. Its _débris_ is found on the exposed shore, extending upwards of 300 yards in length, and covering an area of some 8,000 to 10,000 square yards. It was first examined in 1857 by M. Rousselet, who, notwithstanding its being then submerged, made the fine collection of objects from it now in the Museum at Neuchâtel. The flint implements are particularly well made, and the raw material, which shows a fine yellowish and partially transparent flint, is supposed to have been imported from Gaul. The horn handles and fixers for the stone celts are of varied forms, and there is also a rich assortment of other relics. CHEZ LES MOINES.--Here there is a steinberg, but the antiquities found are unimportant, only a few staghorn implements and some stone celts. Fragments of Roman tiles were also found. ST. AUBIN.--This station was near the shore, and contained a vast steinberg measuring 300 feet by 200. Its investigation was chiefly due to Dr. Clement, of St. Aubin, who made a splendid collection of its antiquities, which show that the settlement belonged almost exclusively to the Stone Age. Specially noteworthy among them are flint-saws in yew and staghorn handles; arrow-points, with portion of the shaft still attached with asphalt; a few beads--one of glass and two of amber; three small gold ornaments; perforated teeth of the bear and wolf or dog. Many of the objects from Dr. Clement's collection are illustrated in the second and third volumes of _Matériaux_, pages 511 and 259 respectively; as well as in Keller's reports. The horn fastenings are extremely varied, and those for celts, intended to be used with wooden handles, terminate either in a split or are squarely cut. The bone implements are particularly well made, and many of the pointers are fixed into handles. The arrow-points are also well chipped, and are of a longish or triangular shape. In the Zürich Museum there is a beautifully chipped dagger of flint, over nine inches in length, from this station. (See =Fig. 185=, Nos. 2, 3, 5, 6, and 9.)
