In June of the following year Mr. Mapleton gives a description of stockaded remains discovered twelve years previously upon the partial drainage of a fresh-water loch at Arisaig, in the parish of Ardnamurchan, Inverness-shire. This loch was of an irregular oval form, and lay in a comparatively level tract of land, with very low braes at a short distance from its shores. It communicated with the sea by a small burn. The crannog was of a rectangular shape (43 by 41 feet), but owing to the surrounding mud it was impossible to ascertain how the foundation of the crannog had been formed. "Outside of the building is a range of sharpened posts, fixed in the bottom of the loch, and inclining inwards towards the crannog, leaving a space of about 3 feet of water between them and the building. These posts are beautifully pointed, being quite round towards the ends, as though made by small sharp instruments. We counted eight still standing on one side. The crannog appears to have been formed altogether of very large round logs, or rather of trees with the bark left on, and the side branches neatly cut off. They are of various lengths: one that we were able to measure being 29 feet long, and 5 feet in circumference, at about 2 feet above the base. Another log was closely fitted to this, so as to extend through the whole breadth of the building. The ends did not overlap, but had been neatly cut or worn off, so as to be placed quite close to each other. "We tried to dig down into the structure, and found at least four layers of these large trunks placed very regularly across each other. We could not dig deeper, as the water began to ooze in; but by using a probe, we felt timbers at a depth of 8 feet below our digging. The wood is chiefly oak, but there are some logs of birch.... On the surface were several large flagstones, especially in three spots. These bore strong marks of fire, and the logs on which they rested were much charred. Beneath and around them we found charcoal, several small pieces of calcined bone, shells of hazel-nuts, and one very small chip of flint, together with several rough angular pieces of white quartz. At each of the four corners of the structure there were two sharpened stakes inclining towards each other and the building, leaving a small space between them; and at one end (viz. the south-east) there was one large log of oak 39 feet long, and 5 feet 6 inches in circumference at the base. Two great logs were nicely rounded off at the end, and a hollow was scooped out in the wood, about 2 or 3 inches deep, and 4 inches broad.
