Amongst the more recently discovered lake-dwellings were one at Lisnacroghera, near Broughshane, and two in Lough Mourne, both localities being in county Antrim. The former came into notice some six years ago in consequence of the discovery in a peat bog of some remarkable iron swords, with bronze sheaths, together with other military weapons. The bog in which these objects were found occupies the site of a former lake, which, till recently, retained so much water as to prevent the working of the peat for fuel. To remedy this the outlet was deepened, and so new or undisturbed portions of the bog were brought within reach of the peat-cutters. The antiquities were found from time to time in a circumscribed area, within a small plot belonging to one of the neighbouring farmers. When attention was first directed to the locality, and the workers questioned as to the circumstances in which the relics came to light, it appears that some kind of wooden structure was encountered, which, however, had been entirely removed before being seen by anyone competent to form an opinion as to its nature. In August, 1866, I visited the locality, and closely questioned the farmer about this woodwork, but failed to elicit any definite information. He was quite clear, however, about the existence of stakes and irregularly disposed beams and brushwood, which at the time he thought little about. From his description, and some remnants of oak beams, some showing the usual mortises, there can, I think, be little doubt that it was a crannog, but of no great dimensions. Close to where the peat had been cut there is an undisturbed structure of stones just cropping through the turf, which may yet turn out to have some relationship with the crannog. As to the relics, there is no record of their association with the crannog beyond the fact of their being found in its vicinity. Canon Grainger, who has taken much interest in this find, has secured for his private museum a large number of the relics from Lisnacroghera, but he fears that, since the crannog has become famous, he has occasionally been imposed upon by having presented to him, as coming from it, objects which in reality had been found elsewhere. This, in my opinion, partly explains the presence of such incongruous objects as are now to be seen in the Canon's collection. Among these are especially some arrow-heads and scrapers of flint which cannot be distinguished from analogous objects picked up on the neighbouring fields. Besides the weapons with bronze mountings, there is in short an assortment of remains which might be classed as belonging to all ages--a stone celt, rubbers, flint arrow-heads and scrapers, down to an iron reaping-hook, a hedge-cutter's knife, and a portion of an old gunlock.
