Lough Eyes (anciently _Tobernasoul_, _i.e._ "the Well of the Eyes"), a small lake only two-thirds of a mile long and a quarter broad, contained a number of crannogs. The largest is 288 feet in circumference, and has a maximum height above the lowest summer level of 10 feet, and is therefore never entirely submerged. "Stockading still exists in a very interesting state of preservation. To the west and north-west the stakes are four deep, and are placed so close together as almost to touch. They are all, or nearly all, of oak, roughly worked, and sharply pointed by a metal axe or adze." A large quantity of broken pottery, like that from Ballydoolough, and some flat pieces, apparently lids, and a club of deer-horn, were found on it. Iron slag, pottery, bones, etc., were found on all these crannogs. (B. 191, p. 553.) DRUMDARRAGH, OR TRILLICK. This lake is now nearly drained, and its crannog, which measured 130 feet in diameter, has recently been re-investigated by Mr. Wakeman, who thus describes the result:-- "Upon examination, the work presented the usual layers of bog, earth, and stones, mixed with small trunks and boughs of ash, alder, beech, yew, oak, and other trees. Here and there, at different levels, were masses of ferns and furze. The outer edge was strongly piled with young trees, of the description above referred to; the great majority, however, being oak. Owing to the softness of the surroundings it was impossible to completely trace the piling on the side of the island which faces the ancient loch bed; but on what may be called the land side the stakes formed six rows placed somewhat regularly, with usually a space of about two feet between each set, sometimes, however, they were close together, nearly touching. The stakes stood about thirty inches asunder, and such of their numbers as were disturbed for the purpose of examination presented sharply-pointed ends, the result evidently of powerful and well-laid strokes of a very keen metallic hatchet or adze.
