One of the crannogs referred to by Mr. Wilson, viz., that in "Loch Inch-Cryndil," or Black Loch, was about the same time subjected to a careful examination, a report of which was drawn up by Charles E. Dalrymple, Esq., F.S.A. Scot. (Proc. Soc. Antiq. Scot. vol. ix. p. 388), from which I quote the following illustrative extracts:—
"The island is oval in shape, 180 feet long, and 135 feet broad in the widest part. It has tolerably deep water round it, excepting towards the nearest shore, a distance of about one hundred yards, where, in dry seasons, it does not exceed 6 or 7 feet....
"In the middle of the island, which is thickly covered with trees of thirty or forty years' growth, but with a few much older toward the south end, a circular mound appeared, resembling a low tumulus, 45 feet in diameter, rising in the centre to about 31⁄2 feet in height, round the edges of which there were, in some parts, traces of a low wall of three or four courses of small stones, like a miniature dike. The island rises gradually from the water to the base of the mound, which at that season (the beginning of October) was about 18 inches above it, so that the top of the mound, which was the highest part of the island, was then about 5 feet above the loch. Spacious cuttings were made in the centre, afterwards extended to the edge of the mound in various directions, with the following results:—The island proved to have been a crannog, formed apparently on a shoal in the lake, composed of shingle over blue clay, the object having obviously been to raise a platform which would be above the water even when the lake was at its fullest, as, even at the present time, there is a considerable rise in the wet months, although pains are taken to keep clear the outfall from the loch. The mound was found to be of earth and stones mixed, extending beneath which, at a depth of 5 feet in the centre, but decreasing in depth towards the edge, was found a flooring of trunks of trees, oak and alder, in two layers, crossing each other at right angles in some places, in others lying rather confusedly. These were mostly not more than 6 or 8 inches in diameter, but one solitary trunk of an oak, near the centre, lying at a higher level, and possibly the remains of a hut or other superstructure, was fully two feet in diameter, although much decayed. These layers of wood were traced as having covered a circular space about fifty feet in diameter, thus agreeing nearly with the size as well as the shape of the mound.... The extent of the mound would appear to have been that of the crannog proper, but the existence of a solitary oak pile, 50 feet from it, on the weather side of the island, makes it probable that either a breakwater had been placed there, as was also supposed to be the case in Dowalton Loch, or a 'chevaux-de-frise' of sharp-pointed stakes for defence.
"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, 23⁄4 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).
