On the other hand, Von Hochstetter believed that he had succeeded in finding traces of these settlements in no less than five lakes in Carinthia, viz. _Wörther_, _Keutschacher_, _Rauschelen_, _Ossiacher_, and _Längsee_. The _Keutschachersee_ is, however, the only one which has yielded positive remains of a sufficiently varied character to render the evidence of Pfahlbauten more than problematical. This small lake, known also as the _Plaschischersee_, which lies to the south of the Wörthersee, contains near its middle a shallow portion which can be readily distinguished from the shore by the rushes which grow over it. The area of the space thus marked out is not great, measuring only 20 fathoms long (Klafter) by 10 fathoms broad, and it is covered by water never less than 4 to 6 feet in depth. Here piles and large beams were seen embedded among stones and mud, but so firmly that they could not be drawn up. Notwithstanding the difficulty of examination, some relics of human occupancy were collected. These, which were subsequently augmented by a further investigation by Mr. Ullepitsch, of Klagenfurt, are deposited in the museum of that town; they consist of portions of half-burnt clay with the impression of wattling, and are supposed to be part of the walls of a cottage. There are also one or two fragments of black and grey pottery, one of which is ornamented (=Fig. 41=, No. 10); a sharpening or grinding stone; a bit of staghorn, together with charcoal; heaps of shells (_Adonta_); hazel-nuts, and portion of a wooden pile. Dr. v. Hochstetter draws attention to the extraordinary number of submerged cairns which he discovered along the shores of the Wörthersee and Ossiachersee. On the eastern shore of the latter he counted no less than 29. These cairns are about 6 feet high, with a diameter of 15 to 20 feet, and their tops are generally covered with 4 to 6 feet of water. It will be remembered that similar cairns were observed in Lake Morat. The only other place which suggested the existence of lake-dwellings was the "Laibacher Morast," in which, a few years previously, a couple of canoes, and some other industrial relics, were dug out of the peat, the full significance of which only now became apparent. Since then the vast morass has yielded a large quantity of the _débris_ of these settlements, which I shall now proceed to describe. LAIBACH MOOR (CARNIOLA).
