Professor Ossowski, in his "Carte Archéologique" (B. 361), gives the following sites of lake-dwellings, none of which, however, have been carefully investigated:—(1) Warlubie (Kr. Swieć). This is a vast peat deposit from which neolithic implements and staghorn hammers have been extracted from time to time. It was visited by Ossowski in the year 1878, who found some fragments of pottery and charcoal. But these merely strengthened the suspicion that the antiquities were due to Pfahlbauten. (2) Similar indications were found at Kowalewo, in the district of Tornú. (3) At Wabrzeźno, in the district of Chelmno, there is a small lake, in which were found a primitive vase, a bronze fish-hook, a stone hammer, and an implement of staghorn. (4) Lankorsz, district of Lubawa.
