ROBENHAUSEN.--This well-known station, which has furnished specimens of lake-dwelling remains to most of the European museums, is situated near the middle of an extensive tract of pasture-land on the south side of the lake. Although its site is now several hundred yards from the lake, there can be no doubt that, originally, it was completely surrounded by water; the nearest land, that on the west, being some 2,000 yards distant. On the east side the old lake-shore is 3,000 yards distant, and towards this, notwithstanding its greater distance, there extended a gangway, the remains of which can still be traced. Underneath the grass there is a thick deposit of peat, which has been utilised as fuel according to the needs of the surrounding community; and a mere glance at the locality shows that the whole expanse is but an encroachment of the peat on what was formerly part of the lake. The meadow belongs to peasant proprietors, among whom it is parcelled into small plots. During the winter of 1857-8 Mr. Jacob Messikommer, the owner of one of these plots, discovered the remains of a pile-dwelling on his portion, and to its investigation he has ever since devoted himself. His efforts were greatly encouraged by Dr. Keller and other members of the Antiquarian Society at Zürich, to whose museum many of the principal relics have been sent. A few years after its discovery, the project of deepening and widening the outlet, which, as it so happened, passed through the lake-dwelling, afforded a splendid opportunity to archæologists for investigating its antiquarian remains. Messikommer was appointed superintendent of the proposed excavations. Since then he has on several occasions when the waters were low, as in the years 1864, 1865, 1870, 1875, 1882, 1884, and 1886, made more or less extensive diggings in different parts of the settlement for the purpose of clearing up obscure or disputed points. Altogether he has made good use of his advantages, and to his intelligent and watchful care we are indebted for a careful record of the relics, as well as a series of shrewd observations bearing on the character and duration of this settlement, which has made it one of the most instructive in the whole range of lacustrine research. The space occupied by the settlement formed an irregular quadrangle, little short of three acres in extent. The piles were made from the round or split stems of trees--oak, beech, and pine being the prevailing kinds. On the supposition that they were placed at uniform distances throughout, Messikommer calculates from the data supplied by the Aabach Canal, which involved an area of about 4,000 square feet, that 100,000 piles were required for the construction of the entire lake-village.
