At the mill, the path turns up the steep wooded hill on the right, and leads through young plantations to a small cottage near the glaciere, where the plantations give place to a well-grown beech wood. Here my conductor startled me by announcing that there was 20 centimes to pay to the farmer of the cave for entrance; an announcement which seemed to take all the pleasure out of the expedition, and invested it with the disagreeable character of sightseeing. The poor driver thought, no doubt, with some trepidation upon the small amount of pour-boire he could expect from a monsieur on whom a demand for two pence produced so serious an effect, and it was difficult to make him understand that the fact and not the amount of payment was the trouble. When I illustrated this by saying that I would gladly give a franc to be allowed to enter the glaciere free, he seemed to think that if I would entrust him with the franc, he might possibly arrange that little matter for me.
The immediate approach to the glaciere is very impressive. The surface of the ground slopes slightly upwards, and the entrance, from north to south, is by a broad inclined plane, of gentle fall at first, which rapidly becomes steep enough to require zigzags. The walls of rock on either side are very sheer, and increase of course in height as the plane of entrance falls. The whole length of the slope is about 420 feet, and down a considerable part of this some grasses and flowers are to be found: the last 208 feet are covered more or less with ice; though, at the time of my visit, the furious rains of the end of June, 1864, had washed down a considerable amount of mud, and so covered some of the ice. There were no ready means of determining the thickness of this layer of ice, for the descent of which ten or eleven zigzags had been made by the farmer. In one place, within 24 feet of its upper commencement, it was from 2-1/2 to 3 feet thick; but the prominence of that part seemed to mark it out as of more than the average thickness. Even where to all appearance there was nothing but mud and earth, an unexpected fall or two showed that all was ice below. Whether the driver had previously experienced the treacherousness of this slope of ice, or whatever his motive might be, he left me to enter and explore alone.
