CHAPTER II.
NOTICES, HISTORICAL AND DESCRIPTIVE, OF SCOTTISH LAKE-DWELLINGS PREVIOUS TO THE YEAR 1878.
It was not till these discoveries on the Continent had attracted universal attention that Scottish archæologists began to look for similar remains in this country. It was then found that early historic references to island forts, and some incidental notices of the exposure of buried islands artificially formed of wood and stone, etc., during the drainage of lochs and marshes in the last, and early part of this, century, had been entirely overlooked. The merit of correctly interpreting these remains, and bringing them systematically before antiquaries, belongs to Joseph Robertson, Esq., F.S.A. Scot., who read a paper on the subject to the Society of Antiquaries of Scotland on the 14th December 1857, entitled, "Notices of the Isle of the Loch of Banchory, the Isle of Loch Canmor, and other Scottish examples of the artificial or stockaded Islands, called Crannoges in Ireland, and Keltischen Pfahlbauten in Switzerland."
This communication was not published in the Society's Proceedings, the explanation of which will be found in the following note, dated June 1866, which forms the introduction to a valuable article by Dr. Stuart, F.S.A. Scot., on Scottish Crannogs:[9]—
"This paper was not printed in the Proceedings, in consequence of Mr. Robertson's desire to amplify his notices of these ancient remains. Other engagements having prevented him from carrying out his design, he recently placed his collections in my hands, with permission to add to my account of Scottish Crannogs anything from his notes which I might care to select. Of this permission I have gladly availed myself, and the passages introduced from Mr. Robertson's collection are acknowledged at the places where they occur.—J.S."
Mr. Robertson's paper, though not published, at once attracted attention, and stimulated so much further inquiry on the part of the members, that, at the very next meeting of the Society, another contribution on the subject was read by Mr. John Mackinlay, F.S.A. Scot., of which the following is an abstract. The paper is entitled "Notice of two 'Crannoges' or Palisaded Islands in Bute, with plans."[10]
Dhu-Loch, Bute.
"The Crannoge of which I am now to give an account was discovered by me in the summer of 1812, and is thus described in a letter, dated 13th February 1813, which I wrote to the late James Knox, Esq. of Glasgow, who immediately sent it to his friend, George Chalmers, Esq., author of Caledonia:—'There is a small mossy lake, called Dhu-Loch, situated in a narrow valley in the middle of that strong tract of hill-ground extending from the Dun-hill of Barone to Ardscalpsie Point, to which valley, it is said, the inhabitants of Bute were wont to drive their cattle in times of danger. I remember, when a schoolboy, to have heard that there were the remains of some ancient building in that lake, which were visible when the water was low; and happening to be in that part of the island last summer, I went to search for it. I found a low green islet about twenty yards long, which was connected with the shore, owing to the lowness of the water, after a continuance of dry weather. Not seeing any vestiges of stone foundations, I was turning away, when I observed ranges of oak piles, and on examination it appeared that the edifice had been thus constructed.
"The walls were formed by double rows of piles, 41⁄2 feet asunder, and the intermediate space appears to have been filled with beams of wood, some of which yet remain. The bottom had been filled up to the surface of the water with moss or turf, and covered over with shingle, or quarry rubbish, to form a floor. The ground-plan was a triangle, with one point towards the shore, to which it had been connected by a bridge or stage, some of the piles of which are still to be traced."
Mr. Chalmers, in his letter to Mr. Knox of 26th April 1813, relative to the above communication, says:—"It goes directly to illustrate some of the obscurest antiquities of Scotland—I mean the wooden castles—which belong to the Scottish period when stone and lime were not much used in building. I will make proper use of this discovery of Mr. Mackinlay."
