CZESZEWO (KR. WAGROWICE).--Although for many years the existence of piles in a particular spot in this lake was known to fishermen, it was not till 1871 that their true nature was recognised by Professor Lepkowsky of Krakow. The lake was surrounded by marshy borders and peat bogs, and at various times its level was lowered, which thus considerably reduced its area. Firewood being scarce in the district, the fishermen were in the habit of pulling out the piles, and in this way the structures were greatly damaged before a competent archæologist saw them. The site of the Pfahlbau was near a large tumulus constructed close to the original lake margin. The area occupied by the piles was in the form of a segment of a circle, the base of which was 250 paces long and its greatest breadth 75. Transverse beams from 10 to 12 feet long were found interspersed among the uprights, which were supposed to have bound the latter together, though neither wedges nails, nor mortises were detected. It was observed that the uprights had their tops charred and that the portions remaining were longer the farther they were placed from the shore, and hence it was supposed that the dwelling had been destroyed by a conflagration.

All ½ real size.] The remains of human industry collected from this station are now deposited partly in the Jagellon Museum at Krakow, and partly in the Archæological Museum at Posen. Among them are fragments of pottery, one being part of a dish perforated with small holes (=Fig. 98=, No. 5), perforated stone and horn hammers and axes (Nos. 1 and 2), one or two plain celts (No. 6), some fragments of clay rings (No. 3), two fragments of human skulls, and a large quantity of the osseous remains of different animals. One object of bronze is said to have been found on this station, and one of the stone implements is only partially perforated, the operation having been unfinished. The stone objects are made of dark granite. Messrs. Kohn and Mehlis have published a small photographic view of the objects in the Krakow Museum, but the more interesting ones, though fewer in number, are at Posen, from which the illustrations here shown are taken. Notices of this lake-dwelling have been published by Count Przezdiecki (B. 156 and 195), by Kohn and Mehlis (B. 338), and by Ossowski of Krakow (B. 361)--the last being in Polish and French. GROSSESEE.--At Alt-Gortzig, in the Grossesee, there was a small island which became visible on the lowering of the lake some 10 feet, around which were found piles and the usual _débris_ of a lacustrine dwelling, among which were pottery with parallel and wavy lines, charcoal, and an iron axe-head, together with numerous osseous remains.
