_Effernan._--In the year 1873, a gentleman desirous to provide his residence with an ample supply of water, decided on bringing it down from this lake, situated at a distance of about two miles, and at a level of three hundred feet above his house. Before a syphon could be placed in working order, it was necessary to reduce the height of the water much below its ordinary summer level, which was effected by clearing and deepening the outlet. When making the cutting the labourers, at about six feet below the surface, came upon a densely-intertwined layer of roots of a pine forest; the trees had evidently attained maturity in the position in which they were found, and they extended also under the water. The forest must have been very ancient, as no lake could have been formed there at the time of its existence. The roots were in the exact position in which the trees grew, and these, with the direction to which their stumps pointed, seemed to indicate that, while the present prevailing wind is the S.W., it must then have been the N.W. Hills and valleys guide the aerial currents, and some convulsion of the earth’s crust may have altered these, and formed the present lake. When, by drainage, the water had been reduced nine feet, there was laid bare a low neck of land stretching into the lake, its outer end being highest. Along this neck of land ran, in irregular order, a row of posts, from four to six inches in diameter, and which, in general, only just topped the ground. At the extremity of the promontory was an unmistakable crannog, circular in form, and with wooden piles surrounding the exterior; the floor was of stone; and one large flag--seemingly the fireplace--took up the greater part of the interior space. Unfortunately, no one specially interested about lake dwellings was at the time aware of this discovery, and the syphon being completed, crannog and causeway became once more submerged.[243] PROVINCE OF CONNAUGHT.
