[Illustration: =Fig. 125.=--LOUGH MOURNE. No. 1 = ¼, and 2 = ½ real size.] Among the relics recorded from this lake-dwelling are "two small stone crucibles" (B. 320), an iron hatchet, part of a canoe, a hammer-stone, a rubbing-stone, two small urns (?), part of a large crucible, charred bones, teeth, shells of hazel-nuts. (B. 439, p. 324.) Flint flakes, scrapers, and arrow-points have been found in the vicinity along the shore, but on the crannog itself only a quantity of fine chips was discovered. Some of these relics I saw in the possession of a young man of the name of Macdonald, who lived in the neighbourhood and took an active part in searching for relics. The iron hatchet turned out to be of exceptional interest. It is a socketed celt, with a loop at one side for fixing the handle, part of which was still remaining in the socket. (=Fig. 125=, No. 1.) Bronze celts of this description are, of course, very common, but specimens made of iron are extremely rare, especially in the British Isles, and only exceptionally to be seen in the museums of Europe. This is the only one hitherto recorded from a British lake-dwelling, and, moreover, it is, as regards size and form, quite unique. It measures 6¾ inches long and 3¼ inches broad immediately above the cutting edge. The longest diameter of the socket is 2½ inches, and this breadth is continued for about two-thirds of its length, except where the loophole causes it to bulge outwards. One of the crucibles, which I believe is now presented to the Belfast Museum, is rather peculiar in having a short projecting handle (No. 2). It would thus appear that the inhabitants of this lake-dwelling practised the art of metallurgy, which would entail at least one fire-proof furnace, and thus partly account for the existence of so many hearths on such a small area. The second dwelling was about 150 yards from the shore, in deep water, and lying over a great depth of quaking mud. It was a small example of the ordinary stockaded island, but owing to the softness of the mud and oozing of water no satisfactory investigation could be undertaken. Mr. Robinson calculates the extent of its submergence at 15 feet. Its entire surface was occupied by a heap of stones which gave it the appearance of a hillside cairn. Digging underneath these stones we came upon a thick bed of heather and brackens interspersed with beams and brushwood. Near the margin were to be seen a few piles and beams rudely mortised, from which one or two long beams radiated towards the centre like the spokes of a wheel. In the first described lake-dwelling no submergence could have taken place, as the lake bottom was composed of compact sand in which the piles had a firm hold.
