What is known as Laibach Moor is an extensive but irregularly shaped plain now nearly all well cultivated, which extends southwards from the town of Laibach to Ober-Laibach, some 12 miles distant. Previous to a series of drainage schemes, executed at various times during the last fifty years, the whole of this plain was a morass or peat bog, and there can be no doubt that in prehistoric times it was a navigable sheet of water. It covers an area of about 85 English square miles, and is interspersed here and there with six or seven rocky eminences, which, when the locality was under water, formed so many islands. It is also intersected by the rivers Laibach, Isca, and some smaller streams, which unite before reaching the town of Laibach, and about half way up it is crossed by the railway to Trieste. Some years ago a new road was constructed along the valley of the Isca, from Laibach to Brunndorf, and in 1875, in the course of excavating a ditch alongside of it, various bone implements and fragments of pottery were turned up by the workmen. Mr. Martin Peruzzi, the proprietor, recognising the archæological value of these objects, at once gave information of the discovery to the authorities of the Landesmuseum at Laibach. This led to an extensive series of investigations, which were continued during the following two years under the care of Dr. Karl Deschmann, curator of this museum. An illustrated report of the first year's operations was published by the eminent archæologist, Baron von Sacken (B. 290), while those of the two following years have found an able exponent in Dr. Deschmann. (B. 302 and 317.) The first year's working revealed the foundations of a pile-dwelling close to the road on its west side, where, by the removal of some 3,000 square yards of peat, quite a forest of piles was disclosed. These were irregularly placed, but on an average they numbered three or four in a dozen square feet. They were made of aspen, poplar, elm, and fir, the last, however, being sparingly used. The peat was about 6 feet thick, and below it was the ancient sediment of the lake into which the piles were driven, their heads now merely entering into the peaty stratum. Between the peat and lake sediment there was a thin layer of organic _débris_, 4 or 5 inches thick, in which alone the relics of the lake-dwellers were found. In the following year some 2,000 square yards were cleared of peat, partly in the same place, and partly on the other side of the road. In this new locality the piles were more closely set and the deposit of peat was a little thicker, but the character of the relics was exactly the same, only a larger proportion of the fragments of pottery were ornamented.
