"Within the stockades were observed two small mounds (upon which the grass was much more verdant than upon any other part of the island), one at the north and the other at the south. Corresponding with the depression between these, and 3 feet under the soil, we found, during the excavation, a flat stone, about four feet square and 3 inches thick, resting on a number of upright blocks of decayed oak. This, no doubt, was a hearthstone. Besides the wooden stakes entering into the formation of the circles, others appear to have been laid horizontally, their beam-like ends showing at that part of the enclosure which was disturbed by the passage of the railway. When the excavation had been carried to the centre, the cut surface presented, from above downwards, the following section: 1st, clay; 2nd, black and grey ashes with small stones and sand; 3rd, bones and ashes, with lumps of blue and yellow clay; 4th, a quantity of grey ashes; and 5th, the horizontal sleepers or stretchers, and hazel branches resting on the peat bottom. "On the same marsh, and about one hundred yards' distance from the island, but nearer to Tonymore Castle, are two other stockaded forts, on a raised plateau. They do not appear to have been islands, as an elevated causeway leads from them to the mainland; but otherwise they resemble the crannoge in their stockaded and mound-like appearance." The antiquities collected on the crannog were presented to the Museum of the Royal Irish Academy, among which were the following, thus described by Sir W. R. Wilde:-- "A very perfect quern, 17 inches in diameter, with the upper surface of the top stone highly decorated; found at the bottom and near the centre of the crannog. Several pieces of iron slag; a barrel-shaped piece of wood 3¼ inches long, hollow throughout, and perforated with six holes; three flat circular stone discs or quoits, averaging 3¼ inches in diameter, and half an inch thick; a most perfect and highly decorated mortar, 8 inches high by 17½ wide, decorated at the corners with four grotesque figures; a stone mould; a four-sided whetstone 20 inches by 3, and eleven fragments of smaller sharpening stones, of which two are perforated. "A large oval and five globular stones; a flat red touchstone of jasper and a stone shot 3 inches in diameter; two weapon-sharpeners of remarkably hard stone. "Two large bone beads; a variegated enamel bead; a large irregularly shaped amber bead; a smaller one of enamel paste, showing a mixture of red, yellow, and blue colours; and also a small blue glass bead. "Two imperfect bone combs, like those already figured in the catalogue at p. 272 (=Figs. 105=, =108=, and =119=). "A bone ferrule 2½ inches long, solid at one end.
