1. _Log Pavement._--About 5 feet deep (measuring from centre of mound), and only a few inches above the level of surrounding water, there was exposed a rude, imperfect, and irregularly-shaped wooden pavement, formed of flattened oak beams. It covered only the central portion of the area contained within the circle of piles, the rest of which was laid with branches and stems of trees. Near the surrounding piles, on the east side, a more carefully constructed arrangement of this wood-work was noticed, consisting of slanting stakes and horizontal beams of various sizes, forming a sort of reticulated and firm flooring, which sloped slightly downwards towards the piles. A similar disposition of the marginal wood-work was noticed elsewhere, especially on the north-west side, in a line with the gangway to be afterwards described; but on the lake side of the crannog the exact mode of its structure was not practically exposed to view, owing to its shelving below the water, but the presumption is that it was pretty much the same all round. On digging beneath this log pavement large beams and brushwood were generally encountered, but the voluminous gushing up of water prevented reliable observations from being made regarding these deeper structures. Occasionally ashes and charcoal were turned up, and in one spot, near the centre, and under my own inspection, the men succeeded in digging downwards more than 2 feet below the log pavement before the water oozed up, in the course of which nothing was turned out but pure ashes, bits of charcoal, and large quantities of the shells of limpets and common wilks. At the bottom of this hole were solid oak beams, apparently flattened; but no sooner were their surfaces exposed than the water rushed in and filled the trench. This gave rise to the conjecture that this under-stratum of remains represented another, and of course an older, period of human occupancy, which also derived some support from the fact that the surface of the log pavement was on a higher level than the tops of the encircling piles. It occurred to me, however, that it was a prepared cavity, and originally intended for the purpose for which it was evidently used, viz. an ashpit; and hence, from want of corroborative evidence, the conjecture that the log pavement is a secondary one, and superimposed on the débris of a former dwelling, must for the present remain _sub judice_. Although portions of mortised beams were in several instances met with, there were no remains found of a circle of stockades having transverse beams, and raised above the log flooring, as was the case at the Lochlee crannog. Had such a structure existed, it would have been removed in all likelihood when the lake was lowered, as the whole wood-work would have been exposed to view. The diameter of the crannog, _i.e._ of the circular area enclosed within the submerged piles, was about 95 feet. No further attempt was made to examine the marginal structure of the island owing to its
