BIALKA (LUBLINER KR.).--In the moor of Bialka, formerly covered with water, there is a small island about 100 paces in diameter, on which tradition says there was once an enchanted castle. Professor Joseph Przyborowski, of Warsaw, made some excavations on the island, and found on the surface some tiles and modern implements, which so far confirmed the tradition of the ancient castle; but upon digging he came upon wooden piles at a depth of four feet. His excavations extended some twenty feet long and nine feet wide, and in the whole of this area he found numbers of piles, as well as cross-beams. Associated with these wooden structures there was also a relic-bed, entirely distinct from the superficial layer, on which he found two well-formed flint arrow-heads, a portion of a perforated axe of serpentine, some flint implements, and broken bones of edible animals. If this site were properly investigated the author prognosticated results of considerable scientific value. (B. 338.) 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. (D) EAST PRUSSIA AND LIVLAND. In the eastern districts of Prussia lake-dwelling remains have been discovered in the following places, which have been more or less investigated and described in various archæological publications, especially in the _Altpreussiche Monatsschrift_:-- ARYSSEE (KR.
