"Upon rowing up to the structure, when it first appeared above the surface of the falling water, the men first came to a kind of rampart, that ran on all the four sides, about 3 feet distant from the structure, and about 18 inches higher than the apparent level of the floor of the crannog. This was formed by large trees that were kept in their place by the upright sharpened posts, whose sharp points projected about 1 foot above the trees. The ends of these trees were scooped out in the same manner as the two that still remain; and they were firmly fixed in their places between the two sharpened posts at each corner, which fitted into the hollow made by the scooping. No signs of a causeway were observed, neither could we detect any symptom of one, though we carefully probed the mud all round. 'Lord Abinger informed me that when a loch on his property, Torlundie, Fort-William, was drained, there was a kind of structure with timbers in it, which were unfortunately scattered and destroyed, as Mr. Stuart had not then made known the existence of crannogs in Scotland, and drawn attention to them.'"--(_Proceedings_, vol. vii. p. 516.) ARTIFICIAL ISLANDS IN MULL. In June 1870, the following note by Farquhard Campbell, Esq. of Aros, Mull, was read at the meeting of the Society of Antiquaries of Scotland.--(_Proceedings_, vol. viii. p. 465.) "The loch called _Na Mial_, in English _Of Deer_, is about a mile south of Tobermory, and about 150 feet above the level of the sea, and 50 acres in extent. There was in the loch one of the artificial islands which are found in almost all the lochs of Mull. I drained the loch, which was only about 6 feet deep of water, blasting a passage through whinstone rock 20 feet deep. The mud under the water is of great depth. Of course, we had to make deep drains round the loch to catch the water. On coming with the drain to the edge of the loch, opposite this island, a large canoe was found 4 feet under the surface of the mud. The canoe was of black oak, 17 feet in length and 3-1/2 feet beam, quite fresh and sound. Several canoes of a smaller size were also found, but near the surface of the mud, and in a half-decayed state. Three boats of modern _clinker-built_ construction, of whose history none of the natives had any knowledge, were also found. I had the large canoe dug out of the mud and put into the sea, in order that, being saturated with salt water, it might be preserved from cracking. There is another loch on my property which has two of these artificial islands. The loch is large--about 1500 acres. I may also mention that, close to the site of the large canoe, I found _a stone causeway laid upon oak-trees_. This was at the same depth under the surface of the mud (viz., about 4 feet). This causeway led direct to the artificial island, which was formed of a quantity of loose stones, on the only rock near the surface of the water in the whole loch."
