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.)
