In consequence of the partial drainage of Lough Mourne during the summer of 1882, while its basin was being converted into a reservoir for the supply of water to the town of Belfast, two artificial islands became exposed which were at once recognised to be the remains of submerged lake-dwellings. Shortly after exposure I visited them in company with Mr. Robinson, the assistant engineer to the Belfast waterworks, and subsequently recorded my observations in the Proceedings of the Society of Antiquaries of Scotland (B. 439), of which the following is a short abstract. The first, which was easily accessible on foot, was very much disturbed by the repeated "howkings" of visitors. Its form, as determined by the area containing the stumps of piles, was irregularly circular, but nowhere exceeding 60 feet in diameter. Included within this area were four small separate elevations, composed of a few stones, clay, and ashes interspersed with burnt twigs and bits of charcoal. None of these elevations had as large a diameter as 10 feet, and it only required one turn over of the spade to reach the undisturbed bed of the lake. Digging on these so-called islets, and in the spaces around them, I found stumps of upright piles and fragments of burnt faggots, the latter forming a thin layer over the true lake-sediment. The piles were closely set, about one or one and a half foot apart, and uniformly occupied the whole area of the dwelling without any appearance of circular stockades; nor was there any semblance of a fascine-structure indicating an artificially constructed island. From the margin or outskirts of the area occupied by these piles a double row of stumps extended towards the shore, which, on being traced, were found to have stopped half way to the ordinary water-level mark. The conclusion which I came to was that this lacustrine dwelling was a true palafitte, over whose wooden platform two or three hearths were constructed of incombustible materials, as stone and clay. Probably these hearths would have been surrounded by some kind of huts. During the conflagration which had destroyed the entire wooden structures (of which final catastrophe there appeared little doubt from the amount of burnt faggots and beams that lay scattered over the lake bed all over the area containing piles), the materials of these hearths would ultimately drop down to the bottom of the lake, still, however, retaining their relative position, and so present the appearance of low mounds over the bed of the lake with the stumps of their supporting piles penetrating them.
