(_a_) _Composition of Lake-bed._--First, or uppermost, there was a stratum of yellowish mud, from 1 to 2 feet thick, mixed with rounded pebbles, and in all respects similar to what was being deposited in the shallow indentations of the lake in the vicinity. Beneath this was a deposit of blackish mud, mixed with decayed organic matter, and varying in thickness from 2 to 2½ feet, in which the tops of the piles appeared and all the relics were found. The third stratum was in composition somewhat similar to the first, and, like it, with the exception of the deeply penetrating piles, was devoid of antiquarian remains. (_b_) _Disposition of the Piles, etc._--The exact dimensions of the area occupied by the piles were not determined, but it appeared to be considerable, and to stretch along the shore within a few fathoms of the ordinary water-mark. The piles were made of different kinds of wood--oak, beech, birch, and fir being the most prevalent--and they varied in thickness from 4 to 6 inches. Sometimes entire stems were used, but more frequently they were split into halves or quarters. They were about 1½ foot apart, and had a kind of systematic arrangement in rows parallel to the beach. Some piles were pulled up, and their tips were found to have been pointed by blunt tools, the cuts of which were, in the estimation of experienced carpenters who had examined them, precisely similar to those which would be made by those very stone implements collected around them. (_c_) _Relics._--The relics were of a mixed character, and included the following:--Stone celts and chisels, some of them being still fixed in their horn handles and fastenings (=Fig. 1=, Nos. 3, 4, 11, and 15); perforated hammer-axes (Nos. 8, 13, and 17); mealing-stones and polishers (No. 12); various implements made of flint, as scrapers, flakes (No. 1), saws (No. 2), and some rude arrow-points (only one being neatly finished, No. 16); various objects of horn and bone (Nos. 6 and 7); also some wooden clubs, fragments of pottery, spindle-whorls (No. 14), shells of hazel-nuts, etc. Among the relics then collected were a bead of amber (No. 9) and a bronze armilla (No. 10). After careful consideration of the facts thus brought to light, Dr. Keller came to the conclusion that the piles had formerly supported a wooden platform, that on this platform huts had been erected, and that, after these had been inhabited for a long period, the whole structure had been destroyed by fire.
