Meantime the Stone Age portion of the principal station was little examined, as the relics were deeply buried. Here, however, were formerly found some iron objects of the La Tène type, viz. a sickle (B. 31, Pl. xiv. 20), and a stone anchor with iron hoops, now in the Museum Schwab. In 1878, when the Government drainage works began to tell on the lake, many articles were picked up. Thereupon Messrs. Vouga and F. Borel commenced systematic diggings, and this set an example to the authorities of the Museum of Colombier and the Société du Musée de Boudry, who likewise started operations with a gang of workmen. Among the objects collected up to 1883 Mr. Vouga particularises the following:-- _Stone._--A number of sharpening-stones of sandstone; a large hollow stone for bruising corn, measuring 1 foot 6 inches by 1 foot 9 inches, and 5½ inches in thickness, having a hollow 2½ inches in depth; some hundreds of hammer-stones, corn-crushers, etc.; portions of stone showing marks of having been sawn, and perforated net-weights; also spindle-whorls, an oval hammer of serpentine ornamented with chevrons; some perforated stone axes, etc.; about 1,200 plain axes, nearly a third of which were still in their horn fixtures. Most of these horn fixtures were inserted in wooden handles, but of course all traces of the latter were generally gone; only 12 nephrite implements were among them. About 1,500 chisels or small celts, only a few of which were of jadeite. One celt was of flint, a very rare thing in this district; and an arrow-point was of polished serpentine. Many thousands of implements of various coloured flints--saws, knives, scrapers, daggers, and arrow and lance-heads. The arrow-points were generally triangular without wings, and a few were lozenge-shaped. The largest flint dagger measures 9 inches in length (Museum Colombier); and some of the saws were still fixed in their handles with asphalt when found. _Horn._--Some 3,000 fixtures for stone hatchets, of which about one-third were perfect. These implements are not bifurcated at their end, as is often the case with those found at Auvernier and elsewhere; and many are only partially made, so that one would suppose there had been here a factory for their special manufacture. There were also perforated hammers, and a great number of chisels, pointers, etc.; also some large plaques whose use is unknown. Out of twenty barbed harpoons one, 8½ inches long, has twelve barbs (No. 8), and one (now in the Museum Boudry) is unfinished. About a similar number of pendeloques or beads, and a few small objects like arrow-points. _Bone._--A great number of pointers and chisels, some of which were inserted into handles; quantities of awls, lance-points, and javelins; thirty daggers; some twenty perforated teeth of the wolf or dog; fifty tusks of the wild boar worked, and some set in handles; bundles of pointed ribs (flax-heckles).
