DAS WEERD.--The existence of the remains of a lake-dwelling at the east end of the Insel Weerd has been known for a long time. The site is close to where a Roman bridge extended from Eschenz to Arach; but the piles are somewhat scattered, and embrace both sides of the river. In 1882 Mr. Schenk succeeded in finding its relic-bed, which he describes as composed of two distinct layers--the upper one being of a dark colour probably the result of the conflagration which destroyed the settlement; and a lower of a yellowish colour, containing much organic _débris_. About 4 cubic mètres of this _Kulturgeschicht_ was examined, and among the relics collected were three human skulls, one of which is perfect, but the others were in bits; a knife, a hair-pin, and some rings of bronze; a copper celt (B. 420b, p. 174); polished stone celts, one of which was made of jadeite. In addition to these, there were various objects of Roman times collected on or in the vicinity of this station, including a tile with an inscription, a bronze statue, Roman coins, etc. In the Rosgarten Museum there is a bronze sword, said to be from this station; also a quern stone 21 inches in diameter, with a central hole 3 inches in diameter. But it is not probable that either of these objects really belonged to the lake-dwellers. The bronze knife, three pins, and some perforated stone implements (=Fig. 28=, Nos. 4 to 7, and 10), are also in this museum, and labelled "Insel Weerd." The human skull has been reported on by Professor Kollmann, who shows it to be dolichocephalic. (_Antiqua_, 1883, p. 69; and 1884, p. 174; _Das Ausland_, 1885, p. 219; B. 462.) MAMMERN.--In the bay above Mammern, at a place called Neuenburgerhorn, there is an extensive area containing very decayed piles. It was investigated by Messikommer in 1861 on behalf of the Historical Society of Thurgau. (B. 41.) The piles commenced about 160 feet from the shore, and extended some 400 feet along, covering an area of 40,000 square feet. The antiquities were all found on the surface, and consisted of hundreds of stone celts, flint implements, pottery, and bones. No small bone tools, nor any trace of the lighter industrial remains or food material, were met with, nor was there a relic-bed underneath. Hence Messikommer concluded that the finer contents of the relic-bed had been washed away by the current of water, which, it seems, is pretty strong at this place. (B. 40, p. 26.)
