SEMPACHERSEE.
In 1806 this lake was lowered to the extent of 6 or 8 feet, and on the shore thus exposed a number of piles became visible, among which it was reported that there were Celtic weapons, hair-pins, and other implements found. "Keltische Waffen, die in vii Bande des Geschichtsfreundes beschreiben sind, Nadeln und andere Gegenstände." (B. 15, p. 99.) But these notices and relics of a past civilisation attracted little attention at the time, and it was only in the light of Keller's discovery of lake-dwellings that the recollection of the find at Sempach was revived and properly interpreted. Colonel Schwab in his lacustrine peregrinations extended his researches also to Lake Sempach, and identified seven or eight stations along its shores, most of which were then on dry land. These settlements were situated near the following places:—Eich, Schenken, Inselchen, Mariazell, Margarethen, and Nottwyl: and in all of them some antiquities either of stone or bronze were collected. (B. 61.)
At the north end, near the site of the lake-dwelling at Mariazell, but about 20 feet from the water and a foot underground, there was a remarkable bronze hoard found. (B. 126.) At a short distance from this there was a human skull disinterred, and along with it a hair-pin and a bronze gouge; but whether or not these objects belonged to the lake-dwellers it is impossible to say. Most of the lake-dwelling remains from the Sempachersee are deposited in the Museum of Lucerne, among which I have noted the following:—One or two discoidal stones; a few clay cylinders with everted edges; whorls of various forms and sizes, some ornamented with lines and pitted impressions; pottery ornamented with lines and triangles, finger-marks, etc.; and four beautifully-worked stone axes ([Fig. 15], Nos. 8, 9, and 10). The bronze find from Maria Zellermoos includes seven winged and two flat celts, a chisel, two knives, one dagger with six rivets, four sickles (one with back spur), and 13 flat bracelets. Some Roman keys, buckles, a few yellow beads of glass (one of amber), etc., are mixed with this find. Specimens of these bronze implements are given on [Fig. 15], Nos. 1 to 7, and 11.

WAUWYLERSEE. (B. 34 and 126.)
To the west of the little Lake of Wauwyl there is an extensive peaty plain, in which, upon the lowering of the lake for further utilisation of the peat, the remains of some curiously-constructed lake-dwellings were discovered. Wooden platforms were met with, resting, not on piles, but upon a series of successive beds of roughly-cut stems lying transversely to each other, the lowest of which reposed on the lake-bottom. Between these layers were branches and brushwood, mixed with clay, and the whole mass was pierced with vertical piles, the tops of which were at least a foot above the upper platform. These layers were as many as five, and the total thickness of the mass when exposed was about 3 feet, but there can be no doubt that, originally, it would have been greater, as there had been considerable condensation of the mass due to decay, especially of the interposing branches. The uprights were not observed to have been in any way connected with the platform, and the only peculiarity in the method of their arrangement was that they were more thickly placed at the corners, as if to keep the wooden mass in position. These artificial structures measured only 10 or 12 feet square, but they were very numerous, and so close that beams from one sometimes reached to the one next it. They were found in various parts of the moor, but in one place they were crowded into a rectangle measuring 90 feet by 50, which was surrounded by several rows of upright piles, as if for common protection. The upright piles were made of oak, alder, or fir, and they penetrated deeply into the shell marl—the stoutest being of oak, measuring 5 inches or more in diameter. It is noteworthy that the lowest horizontal woodwork lay on the shell marl, showing that these dwellings were constructed before the peat commenced to grow. The peat is now at least 6 feet thick., i.e. 3 feet of peat lying above the uppermost platforms.
No antiquarian remains were found underneath the wooden structures, but mostly in the intervals between them, where the objects lay almost directly over the shell marl. The settlement appears to have come to an end before the Bronze Age, as no metal object has been met with. A small glass bead is therefore of interest, as showing that the colonists must have had commercial relations with distant countries. Among the other antiquities are the following:—Stone celts (some of nephrite) hafted in staghorn fixings, and flint implements; chisels, pointers, flax-hecklers, etc., of bone; a lump of asphalt, harpoons of staghorn, knives made of yew, and various fragments of pottery with perforated knobs. In the Museum of Lucerne there are a few things, among which are one or two objects showing that the art of boring stone was known ([Fig. 16], Nos. 1 and 2).
