The general plan on which this gangway was constructed appeared to be identical with that adopted by the crannog-builders of Lochlee. Upright piles, singly and in groups, were placed in a zigzag fashion, between which the horizontal beams stretched, fan-like, and so formed a sort of lattice-work, with empty lozenge-shaped spaces between. From one of these holes or meshes, some 5 feet below the surface of the ground, a fine granite quern-stone was extracted. The piles projected some 2 feet or more above the body of the gangway, but there was no appearance of the remains of a platform. The depth of the lower portion of the gangway could not be reached. It would thus appear that at least the transverse beams of the gangway were originally under water--a remark equally applicable to that at Lochlee; and it is highly probable that the primary purpose of this so-called gangway was to supply, on emergencies, a means of secret access to the crannog. 4. _Composition of Mound._--The surface of the mound was composed of coarse grass, having tough matted roots spreading in a thin layer of soil, which overlay about a foot and a half of stones and rubbish, in which no relics were found. Below this the materials were of a very variable character; sometimes vegetable mould, stems of grasses jointed like straw, and beds of heather and moss, which could readily be separated into layers; and at other times heaps of ashes and charcoal mixed with quantities of the shells of wilks, limpets, and hazel-nuts. Intermingled with this heterogeneous mass were large and small stones, broken bones, portions of deer horns, and the relics to be afterwards described. Though one or two ashpits, mostly composed of fine ashes, sea-shells, and broken hazel-nuts, were distinctly discernible in the vicinity of the fireplaces, no regular refuse-heap was met with; and the broken bones and horns seemed to be dispersed over the general area of the crannog.
