Regarding a crannog in Loch Lomond,[16] in the neighbourhood of a stone cashel on shore, from which large mortised joists were disjoined in 1714, and used by a gentleman in that country for building a house, see extracts from Dr. Robertson's notes, Proc. Soc. Antiq. Scot. vol. vi. p. 132.
Loch of the Clans, Nairnshire.
In 1863 a paper by Dr. Grigor of Nairn was read at the Society of Antiquaries of Scotland, in which the author describes a curious cairn with "oak beams and sticks cropping out in it," and surrounded by a ploughed field which was formerly part of the basin of the Loch of the Clans, from which I give the following extracts:—
"On getting down into the cairn, we found that all the wood in sight was chiefly the remains of rafters, and inclined upwards at about an angle of 25 degrees, so as to form an upright roof. These, however, had been broken across (as represented on the sketch, Plate I.), no doubt by their own partial decay and the superincumbent weight of stones. On further clearing and digging, we came upon four sides or walls, each about 3 feet in height, and making an irregular square. These were formed of trees of oak, comparatively sound, and about thirty years' probable growth. On the west side, there were seven trees piled horizontally, one above the other; the third from the ground had another alongside it. Seven trees also formed the east side. The north side was made up of a foundation of small boulders, then two horizontal trees, over which projected a few rafters, and then another tree. At the east end of this wall there was a mortised opening, in which, in all probability, an upright support had been placed. The south side had been, to all appearance, partially removed when that end of the cairn was carted off by the tenant-farmer, and only one tree at the bottom was seen. These sides are correctly represented in the accompanying sketches, and the scale renders it unnecessary to particularise measurements. The floor was the mud bottom of the old loch, and there were two small trees stretching from east to west, with the appearance of decayed brushwood throughout, and a boulder stone here and there. Not exactly in the centre, but nearer the south-east corner, lay a few boulders bearing marks of fire, and having portions of charcoal around them. This was all that could be seen as a hearth.
"Nothing of any interest was found in the way of clearance. There were portions of decomposed bones, a bit of pottery (evidently modern), the mouth-piece of a horn spoon, and a cockle shell, and these probably had fallen through the cairn.
"To all appearance the rafters started from the ground in three tiers, having different angles of inclination, though those of the roof seemed to have run up pretty much together near the ground. These were bound down by beams crossing and recrossing in all directions, which imparted greater strength. Beyond two mortised openings no other mode of fastening could be seen."
