32 also, are less decayed, and project above the mud farther than those of the preceding epoch. M. Morlot considers that the horizontal platform rested upon the top of these piles, at such a height as to allow for all ordinary variations in the level of the water. M. Suter, however, supposes that in some cases, at least, the platform was not attached to the perpendicular piles, but rested upon the water, rising and sinking with it. The structure of the Pileworks at Wauwyl, in the Canton of Lucerne, certainly seems to favour this view. It was composed of four rectangular divisions, separated by narrow channels, over which, no doubt, bridges were thrown, and through which canoes might pass. The piles were less numerous than usual, and were grouped principally round the outer edge of the platforms. In this case they have been preserved by peat; they are from three to four and a half inches in diameter, ail rounded, and not formed of split timber. In order to ascertain their length, M. Suter dug up two of them; the longest penetrated four feet through the peat, and ten feet six inches into the ancient bed of the lake; the other, also four feet through the peat, but only four feet six inches lower. M. Suter examined the piles carefully, but fruitlessly, to ascertain any manner in which the platform can have been attached to them.

The platform itself consisted of five layers of trees, curiously and carefully fastened together by clay and interlaced branches of trees, but like the perpendicular piles they were examined in vain for any traces of notches, mortises, holes, ligatures, bolts, or any other contrivance, by which the upright piles and the platforms could have been fastened together.

Not only were the debris of their repasts, and other rubbish thrown into the water, but more or less valuable weapons and instruments must have been sometimes lost in this manner, especially as children formed, of course, the usual proportion of the population. Many of the articles presently to be mentioned, were however, in all probability, engulphed at the destruction of the Pfahlbauten, some of which were perhaps burnt and rebuilt more than once.

The number of stone implements which have been already found is quite astonishing; at Wangen, in Lake Constance, many hundred weapons of various sorts have been discovered, and a great number also at Moosseedorf, Wauwyl and Robenhausen, in none of which places has a single piece of metal been as yet met with, a fact which, taken in connexion with the great number of bronze implements which have been collected from other Pileworks, clearly indicates that the settlements above mentioned, belonged to the age of Stone. Not only, however, is metal absent, and not only, as we have already seen, does the Fauna indicate a greater antiquity, but the stone weapons themselvess are less varied and less skilfully made. Most of them are made from rocks which occur in Switzerland, though it is probable that the flint was brought from France. The absence of any great blocks of this valuable material in Switzerland accounts for our not finding any of the large, flat axes which are so characteristic of northern Europe, and especially of Denmark. At Wangen, the
