"At different levels, from that of a few inches above the timber flooring to 3 feet higher, and over the whole mound, were found many fireplaces, one or two covered over with two long stones, leaning against each other lengthways, like the roof of a house, but most of them formed by placing two long narrow stones (fragments of the rock of the district, which breaks off easily in that form) parallel with each other, leaving a space between, which was paved with small stones and formed a hearth. Large quantities of bones of animals, mostly more or less burnt, and, whether flat or round bones, frequently split, were found mixed with the ashes and charcoal which lay in and around these hearths, in some places extending over wide spaces, which were marked, also, by masses of burnt yellow clay." At different levels, in different parts of the mound, were found the following objects,[23] the description of which I take from _Proc. Soc. Antiq. Scot._ vol. ix. p. 381:-- Double-margined comb of bone, imperfect, 2-3/4 inches across, formed of separate pieces, enclosed between two transverse slips of bone, fastened with three iron rivets, and ornamented with a central row of dots and circles, and two similar rows at the side of the cross piece, having a running scroll pattern connecting them. A zigzag ornament forms a band across the end (Fig. 30). [Illustration: Fig. 30.--Bone Comb (1/1).] A flat loop of bronze, 1-1/4 inch in diameter. Part of the rim of a large vessel of cast bronze, 3 inches in length. Portion of an armlet, of greenish glass, with a blue and white twisted cable ornament running round it. Copper coin much defaced. Copper bodle of Charles II.[24] CRANNOG AT TOLSTA, LEWIS (1874). The following account of a crannog is from a letter by Peter Liddle, Esq., to the secretary of the Society of Antiquaries of Scotland (_Proceedings_, vol. x. p. 741):-- "In a lake recently drained at Tolsta, I have examined a crannog which seems to me to possess some interest. A drain has been cut through part of the crannog, which affords a section of its construction. At the outside there is a row of piles 5 or 6 inches diameter, then large stones, then another row of piles, then heather and moss--the whole covered with earth and gravel. The remains of three houses built of unhewn stones are still visible upon it. All round the crannog, but inside the outer row of piles, there is an immense quantity of shells, plentifully intermixed with bones, ashes, and twigs of trees. The shells are those of the ordinary edible shell-fish, the mussel being the most common. The bones are chiefly those of deer, and the small Highland sheep still found on the island. The only implement I found was part of a stag's horn, with the brow-antler thinned. Three hollowed stone vessels or knocking-stones were found on the surface, but they were destroyed or lost sight of. A causeway of large stones under water led to the crannog."
