The industrial remains collected from time to time at Niederwyl consist of:--Wheat, barley, flax, cakes of bread, wooden implements, clay weights (=Fig. 26=, No. 3), stone hatchets (Nos. 7 and 8), flint saws (No. 1) and scrapers; some well-made dishes (Nos. 4, 5 and 6), one a remarkable jug (No. 6) with handle; another, of black earthenware, had been mended with asphalt. A strip of birch-bark (now in the Museum at Zürich) had been neatly sewn (No. 10). In the same Museum there is a stone (perforated) axe-hammer head which vies in elegance of workmanship with any from Scandinavia (No. 9). Recently Messikommer has come to the conclusion that the _Packwerkbau_ at Niederwyl existed during the early Bronze Age, as he found a piece of oak wood having cuts which could not have been made by a stone implement. From various considerations of the more recent facts brought to light in the course of his frequent excavations here and at Robenhausen he enunciates the opinion that wherever split oak beams or piles are found we may with certainty conclude that the settlement belongs to the early metal age. ("Man darf mit Bestimmtheit annehmen, dass alle jene Niederlassungen, in welchen gespaltenes Eichenholz in grösserer Menge zum Vorschein kommt, auch das Metall in einfacher [Kupfer] oder zusammengesetzter Form [Bronze] gekannt haben.")

Here for some time fragments of pottery, stone hatchets, horns and bones of various animals, were met with in the peat; but in August, 1884, Messikommer discovered the actual piles associated with the usual objects of a Stone Age dwelling. The area of this Pfahlbau was small, measuring only 13 yards by 10. Its site lay near the margin of the peat, and the antiquities were met with 1 foot under the surface. Among these were a small earthenware dish or cover ornamented with four prominences and a few rows of punctured dots (No. 2), several wooden dishes in all stages of manufacture, entire handles of stone hatchets, worked horn, etc. A crucible similar to those from Robenhausen was also found near the same place. Among the osseous remains are portions of a skull of the urus with both horn-cores attached. The other animals represented are the bison, stag, ox, pig, goat, etc. (B. 420d.) GREIFENSEE.
