From an examination of the bones collected the following animals were identified, viz.:--horse, ox, goat, sheep, pig, dog, fox, deer, and roe. In the Virchowsee a little to the north of Persanzig there is a huge Burgwall surrounded by water, in which the remains of piles have been found. (B. 165.) STREITZIGSEE.--On the lowering of this lake a very large assortment of piles became exposed, but although several excavations were made, both by Professor Virchow and others, no decided results were obtained bearing on their character and scope. (B. 165.) LÜBTOWSEE.--Another locality which has furnished remains of pile-dwellings lies to the right of the Oder, in the vicinity of Lübtow. (B. 165.) Here the river Plöne traverses a long lake, and on its being lowered in 1859, an extensive area covered with piles became visible towards its northern end. It is said that many relics were found among these piles, some of which were collected by the proprietor; but the idea of their belonging to lake-dwellings was not mooted till several years afterwards. Professor Virchow visited the locality in 1865, and again in 1869, and on the latter occasion he made extensive excavations, which convinced him that this was a regular lake-settlement. Later on the foundations of a quadrangular wooden building came to light, from which, owing to its being 3 feet under the late lake level, Mr. Kühne inferred that the lake must have formerly stood at a lower level. That this structure, however, as well as the piles, belonged to the Iron Age, he says there can be no doubt whatever, as the antiquities collected in both were precisely similar, being generally iron objects, such as swords, lance and arrow-heads, stirrups, spurs, knives, and bricks of the thirteenth or fourteenth century. In the rectangular building, in addition to such objects, were found a helmet and greaves. But what was considered still more singular, there was found among the piles a number of stone chisels and hammers, together with one bronze celt. (B. 119, 2^o ed., p. 629.) Adjacent to this lake at Bonin, and deeply buried in the turf, indications of wooden structures came to light which, in 1872, attracted the attention of Professor Virchow, who, in company with the local antiquaries, made excavations which revealed structures analogous to those in the Persanzigersee. (B. 227.) In excavating they passed through the following distinct layers:--First, 5 to 8 feet of peat; second, some thin layers of marl, sand, and mud; and third, a relic-bed, 2 to 4 feet in thickness. The woodwork appeared to the investigators to have been cut by sharp metal tools. Among the relics collected were four sharpening-stones, a few perforated staghorn hammers, a bone chisel 6½ inches long, some large horn handles, a small iron knife, bits of leather, fragments of wooden dishes, and part of a boat. Pottery was also found which belonged to the Burgwälle type.
