By the removal of the mould from year to year, this hollow had been partially converted into its pristine aqueous condition, which, however, could hardly be dignified by the name of a lake, being nothing more than a pond, some 40 yards long by 30 broad. Here a semicircular area containing oak piles was detected, which measured about 22 feet in diameter. The piles were 7 to 10 feet long, and 7 to 8 inches thick, and interspersed among them were some horizontal beams. Associated with this wooden structure were found various kinds of antiquities--viz. four polished or chipped axes of flint (=Fig. 95=, Nos. 2 and 3), two perforated axe-hammer heads of diorite (No. 4), a portion of a third (No. 7), and some flint daggers (No. 1) and flakes. A four-cornered mortar of grey basalt, 3½ inches high by 2½ broad (No. 8); the corners of this vessel are rounded, and its surface neatly polished. A hand-millstone or quern, 1 foot in diameter and 2½ inches thick, made of porous basalt: this quern had a hole in the centre, with two swallow-tail notches on each side for fixing the handle, and its under surface was worked into a series of narrow grooves, precisely similar to those of Roman and post-Roman times. There were also some spindle-whorls (No. 19), a portion of a clay weight, and fragments of dishes of black and red pottery, some of which had handles. The bones were all of the ordinary domestic animals. _Marine Pile-dwellings._--The spirit of antiquarian research aroused in the neighbourhood by these discoveries, led to the recognition of the remains of marine pile-dwellings (Meerpfahlbauten) in the bay of Wismar. Attention was first directed to this subject by Mr. Mann, who pointed out that for several years past flint hatchets, daggers, and knives, as well as various objects of horn and bone, and even bronze implements, were frequently turned up by the dredging machines used in the harbour. The matter, however, excited no interest among the workmen, and thus many valuable objects were re-deposited in deep water along with the dredged mud. It was reported that some bronze objects had been sold to the smith, Vossech, and melted; while others of stone and horn had been dispersed. It appears also that at a particular place called the Baumhaus piles of oak had been observed. In 1864 the workmen engaged at the dredging machines, having their attention called to the matter, reported the existence of piles at various places in the bay, one of which was between the shore and the little island Wallfisch, and the other close to the island Poel. One peculiar horn object which had been sent to the museum was supposed to have been a _Taschenbügel_ or rim for a pouch. (B. 100, p. 101, and vol. xxix. p. 132.)
