Mr. Kinahan says that Reed's Island, Shore Island, Ash Island, and Island M'Coo, in Loughrea, are crannogs; while Blake's Island may also be one. From Shore Island 300 tons of bone were procured, among which was the head of a _Megaceros Hibernicus_ which measured 13 feet from tip to tip of its horns. Amongst many relics found here made of stone, horn, and wood were a few metal objects, as iron shears, a brass pin, a crozier made of brass, a battle-axe, a cast for a coin, and a hammered iron vessel. The only other writer on Irish crannogs to whom I find it necessary to allude in a special manner is Mr. W. F. Wakeman. Personally acquainted with Petrie and Wilde, and probably deriving inspiration from their enthusiastic devotion to archæology, and an eye-witness of the first great crannog find at Dunshaughlin, Mr. Wakeman has ever since been a careful observer of the antiquities of his country. His special attention to crannogology dates only from 1870, but since then scarcely a year has passed without his pen and pencil being in requisition to record some fresh discovery in this field of research. In early times no district in Ireland presented more favourable conditions for aquatic retreats than the county of Fermanagh, with its countless lakes and bogs, interspersed and embosomed in the primeval forests which were then extant. These advantages would appear to have been fully recognised by the crannog-builders, as we find more remains of these lacustrine abodes here than in any other part of the island. The number of crannogs now recorded in this county amounts to about 40, but of course this is by no means the full quota that might be disclosed by the adoption of a general system of exploration. Such exhaustive methods of research have not as yet, however, taken deep root in Ireland, so that the few reliable data of this character that have come to light we cannot afford to pass over, even in this brief sketch. The following extracts from Mr. Wakeman's reports are selected for the purpose of illustrating the structure of these remains in this part of Ireland, and the general character of the relics left on them by their inhabitants. BALLYDOOLOUGH. Ballydoolough ("town of the dark loch") is a small sheet of water some five miles from Enniskillen, in which there is a small island which, in 1870, was recognised as a crannog, and subsequently investigated.
