No views create such lasting impressions as those which are seen but for a moment, when a veil of mist is rent in twain, and a single spire or dome is disclosed. The peaks which are seen at these moments are not, perhaps, the greatest or the noblest, but the recollection of them outlives the memory of any panoramic view, because the picture, photographed by the eye, has time to dry, instead of being blurred, while yet wet, by contact with other impressions. The reverse is the case with the bird’s-eye panoramic views from the great peaks, which sometimes embrace a hundred miles in nearly every direction. The eye is confounded by the crowd of details, and is unable to distinguish the relative importance of the objects which are seen. It is almost as difficult to form a just estimate (with the eye) of the respective heights of a number of peaks from a very high summit, as it is from the bottom of a valley. I think that the grandest and the most satisfactory standpoints for viewing mountain scenery are those which are sufficiently elevated to give a feeling of depth, as well as of height, which are lofty enough to exhibit wide and varied views, but not so high as to sink everything to the level of the spectator. The view from the Grand Tournalin is a favourable example of this class of panoramic views. We descended from the summit by the northern route, and found it tolerably stiff clambering as far as the Col. Thence, down the glacier, the way was straightforward, and we joined the route taken on the ascent at the foot of the ridge leading towards the east. In the evening we returned to Breil. There is an abrupt rise in the valley about two miles to the north of the village of Val Tournanche, and just above this step the torrent has eaten its way into its bed and formed an extraordinary chasm, which has long been known by the name Gouffre des Busserailles. We lingered about this spot to listen to the thunder of the concealed water, and to watch its tumultuous boiling as it issued from the gloomy cleft, but our efforts to peer into the mysteries of the place were baffled. In November 1865, the intrepid Carrel induced two trusty comrades—the Maquignaz’s of Val Tournanche—to lower him by a rope into the chasm and over the cataract. The feat required iron nerves, and muscles and sinews of no ordinary kind; and its performance alone stamps Carrel as a man of dauntless courage. One of the Maquignaz’s subsequently descended in the same way, and these two men were so astonished at what they saw, that they forthwith set to work with hammer and chisel to make a way into this romantic gulf. In a few days they constructed a rough but convenient plank gallery into the centre of the _gouffre_, along its walls; and, on payment of a toll of half a franc, any one can now enter the Gouffre des Busserailles.
