At first sight, the farther end of the cave was the most striking. The water which comes from the melting snow down which we had passed in reaching the glacière, had cut itself deep channels in the floor, and through these it coursed rapidly till it precipitated itself into a large pit or _moulin_ in the ice, at the lowest point. This pit, a will be seen by the section of the cave given on p. 174,[71] terminates the glacière; and the rock-wall at the farther edge falls away into a sort of open fissure, down which magnificent cascades of ice stream emulously, clothing that side of the pit, which would otherwise be solid rock. We cut a few steps about the upper edge of this _moulin_, to make all safe, and proceeded to let down a lighted candle, which descended safely for 36 feet, showing nothing but ice on all sides; it then came in contact with one of the falls of water, and the light was of course extinguished. We next tied a stone to the string, and found that after 40 feet it struck on ice and turned inwards, under our feet, stopping finally at the end of 51 feet; but whether it was really the bottom of the pit that stopped it, or only some ledge or accidental impediment, we could not determine. The diameter of this pit might be 3 yards, but we took no measure of it. At the extreme right of the cave we found another pit, a yard and a half across, two-thirds of the circumference of which was formed by the plateau of ice on which we stood, and the remaining third by a fluting in the wall of rock. The maire said that, two years ago, this hole was not visible, being concealed by a large ice-column which had since fallen in. Here again I let down a lighted candle, with more hopes of getting it to the bottom, as no part of the cave drained into the pit. The candle descended steadily, the flame showing no signs of atmospheric disturbance, and revealing the fact that the opposite side of the pit, viz. the rock, which alone was visible from our position, became more and more thickly covered with ice, of exquisite clearness, and varied and most graceful forms. As foot after foot, and yard after yard, ran out, and our heads craned farther and farther over the edge of the pit to follow the descending light, (we lay flat on the ice, for more safety,) the cries of the schoolmaster became mere howls, and the maire lapsed into oaths heavy enough to break in the ice. It is always sufficiently disagreeable to hear men swear; but in situations which have anything impressive, either of danger or of grandeur, it becomes more than ever unbearable. I remember on one occasion over-taking a large party in the descent from the Plateau to the Grands Mulets, in a place where the snow was extremely soft, and any moment might land one of us in a crevasse; and I shall never forget the oaths which caught my ear, from a floundering fellow-countryman enveloped from the waist downwards.
