in diameter, seems to have been the only one on the hill not previously rifled, and yielded a most astonishing collection of objects to its explorer. The cell was of the usual cruciform plan, 24 feet from the entrance to the rear, and 16 feet across the lateral chambers. In the passage and crypts of this cairn Mr. Conwell collected some 300 fragments of human bones, which must have belonged to a considerable number of separate individuals; 14 fragments of rude pottery, 10 pieces of flint, 155 sea-shells in a perfect condition, besides pebbles and small polished stones, in quantities.
The most remarkable part of the collection consisted of 4884 fragments, more or less perfect, of bone implements. These are now in the Dublin Museum, and look like the remains of a paper-knife-maker's stock-in-trade. Most of them are of a knife shape, and almost all more or less polished, but without further ornamentation; but 27 fragments appear to have been stained, 11 perforated, 501 engraved with rows of fine lines; 13 combs were engraved on both sides, and 91 engraved by compass with circles and curves of a high order of art. On one, in cross-hatch lines, is the representation of an antlered stag, the only attempt to depict a living thing in the collection.
Besides these, there were found in this cairn seven beads of amber, three small beads of glass of different colours, two fragments, and a curious molten drop of glass, 1 inch long, trumpet-shaped at one end, and tapering towards the other extremity; six perfect and eight fragments of bronze rings, and seven specimens of iron implements, but all, as might be expected, very much corroded by rust. One of these presents all the appearance of being the leg of a compass, with which the bone implements may have been engraved, and one was an iron punch, 5 inches long, with a chisel-shaped point, bearing evidence of the use of the mallet at the opposite end.
Cairn D is the largest and most important monument of the group, being 180 feet in diameter, and though it is very much dilapidated, the circle of fifty-four stones which originally surrounded it can still be traced. On its eastern side the stones curve inwards for about twelve paces, in the form universal in these cairns; but though the explorers set to work industriously to follow
