_Piles._--The piles were from 8 to 12 inches in diameter, singly and irregularly placed, but sometimes in groups; some were hard and black (oak), and others soft, but they bore no traces of any cutting implements. In some instances they were surrounded with heaps of stones. They penetrated deeply, and one which was pulled up measured 18 feet in length. No traces of a gangway stretching to the shore could be discovered. _Relic-bed._--Below a thin covering of vegetable-mould there was a peaty bed about 16 inches thick, and underneath this, lake-marl containing various kinds of fresh-water shells to the extent of 3 feet 4 inches. To this succeeded the _strato archeologico_ with its various contents--decomposed organic matter, broken bones, fragments of pottery, flint implements and other worked stones, bits of straw, reeds, charcoal, clay plaster, burnt faggots, etc. This bed was about 12 inches thick, and its matrix was of a yellowish-black colour, which, when cut into, had a doughy consistency and emitted a strong sulphurous smell. _Relics._--The rough stone implements were made out of the limestone of the neighbouring hills, very seldom of sandstone, but more frequently of flint from the spurs of the Alps. These flints were in considerable numbers in the form of chips, nuclei, and unfinished implements, very few of which were well formed; a few rudely-formed arrow-points, lance-heads, knives, and saws or scrapers; pebbles of limestone, probably hammer-stones; stone discs, 2 to 4 inches in diameter (only one was perforated); also numerous sling-stones made of sandstone, basalt, and serpentine; one fragment of granite, flattened and polished on all the four sides, but only one small polished stone celt. Many of the bones were worked, and there were tynes of staghorn, sharpened at the top and perforated at the base; also pointers, spear-heads, spatulæ, and splinters of all kinds. The fragments of pottery were so plentiful that a handful of mud could not be taken up without finding some pieces in it. Amongst some thousands of fragments about 50 vessels in a more or less perfect condition were picked out. They are all of a dark colour, with handles attached, generally below the rim, and flat bases. Some of them have everted lips, and many are ornamented with knobs, depressions, or raised ridges (circular, wavy, or confluent). Some of the handles approach the form known as _anse lunate_, others terminate in a round button (_ansa mono-appendiculata_). One small bowl had two handles. The paste was of two qualities: one fine, and the other mixed with coarse bits of gravel, quartz, and carbonate of lime. Numerous specimens of spindle-whorls. They are flat circular cakes of clay, like small wheels, perforated and unornamented. _Organic Remains._--Fruit of the water-chestnut (_Trapa natans_), kernels of cherries, hazel-nuts, acorns, bramble seeds, etc.
