_Lough Naneevin_ is situated in the townland of Gortacarnam, barony of Moycullen. In the summer of 1865, G. H. Kinahan observed, in this lake, a crannog which is described as oval in form, about one hundred and fifty feet in length, seventy-five feet wide, and on the south a narrow causeway, then partly submerged, had joined it to the mainland. The island bore traces of having (since last inhabited) been covered with water _at least_ two feet higher, for shell marl was deposited on the portion below that level. On the south shore of the crannog there was a row of round oak piles, four inches in diameter, and on the S.W. shore were two rows of similar piles, five feet apart; alongside them were oak beams, and there was a double row of piles, seemingly part of a wall, bearing north and south. No piles were observable on the east of the crannog, but there was an irregularly-laid flooring of beams of ash, oak, and sallow; from these latter, it was supposed, had sprouted the sallow trees, which at that time formed a fringe round the island. The piles had been pointed with a sharp-cutting instrument; therefore metal had been in use either when the crannog was constructed, or repaired. Six small excavations made near the centre of the island, where the surface of the crannog was three feet above the water-level, disclosed the following section:-- ft. in. Bog, with a few bones, sticks, and stones, 3 6 A bed of regularly laid fern-stalks and leaves (_Pteris } aquilina_, or brake fern), on a flooring of } wicker-work, made of hazel rods, about an inch in } diameter; over the ferns were a few bones and a } quantity of nutshells, } 0 6 Bog-stuff, mixed with branches, and containing a few } stones and logs of timber, (over) } 5 0 About a foot below the water-level were traces of what G. H. Kinahan considered to be a basket-flooring; and a large flag-stone, used as a hearth, was found resting on an accumulation of wood-ashes, three feet in depth. Some distance to the west was a long rude bench (or perhaps the foundation of a wall) formed of stones. The height of the water prevented excavations outside the crannog, therefore few bones were met with, but a little east of the fireplace was the probable site of the kitchen midden.[245]
