The excavation of this barrow was commenced on the 17th of July 1854. It was found to contain graves, in one of which was an urn with a quantity of burnt bones and ashes. It was formed out of a micaceous stone not belonging to Orkney. It was 1 foot 9 inches in diameter, about 18 inches deep, and 5 feet 10 inches in circumference, the rim, which projected on the outside all round, was an inch and a half wide, the kist in which it was deposited was 2 feet and a half in length, and 2 feet in width, but the side stones which protected the kist were nearly 6 feet in length, and at the angles, and on the outside of the kist were quantities of small rolled pebbles and gravel, probably intended to assist in draining off water. Clay was placed inside the kist at the different angles; the flags were about an inch and a half thick, but much decayed; the cover stone was of an irregular shape, about 4 feet long and 2-1/2 wide; the urn rested upon the corners of four flags; it was partly decayed, and could not be removed till after an interval of two days, when I succeeded in raising it. It is now in the Museum of the Society of Antiquaries at Edinburgh, to whom I presented it, with the consent of Mr. Balfour. In another grave within the same barrow was found a small urn composed of baked clay and gravel, nearly filled with soil, and only one or two small pieces of bone. It was brought to Kirkwall, but could not be preserved, in consequence of its decayed condition. It was 5 inches in diameter, 17 in circumference, and 5 deep. The kist was 2 feet 9-1/2 inches long, and 1 foot 7 inches wide. The bones, in this instance, had not been placed in the urn, but were laid on a flagstone in the north-west angle of the kist. It is not improbable that further investigation might lead to the discovery of other interments within the same barrow, since neither of those before described were in the centre of the tumulus, and several instances have occurred where they have been found near the outside.
