There were in all four columns of ice in the cave, only two of which were of any considerable size. One of these was peculiarly striking from the very large grain which its structure displayed; it measured 19 feet across the base, being flat towards the extremity of the cave, and round towards the entrance. Three thermometers in various parts of the glacière gave all the same temperature, namely, a fraction under 33° F.: a rough French thermometer gave 1/2° C. The extreme wall of the cavern was completely covered by a layer of stalagmitic material, and some of the forms the substance assumed were sufficiently striking. In contact with the wall, though standing clear of it in parts where the wall fell inwards, stood a thick round column of the same material, shaped like the ordinary ice-columns of the glacières, with a cavity near the base, and in all ways following the usual laws of such columns. Considering that I had observed a layer of limestone-paste collecting on one of the ice-columns of the Glacière of La Genollière, I could not help imagining that this stalagmitic column had been originally moulded on a norm of that description. It had a girth of 12 feet in the part where we were able to pass the tape round it. Its surface was smooth; but when we drove a hole through this, with much damage to the _pic_ of my axe, we found that the interior was in a crystalline form. There was, on the whole, very little to be seen in the glacière. Had it been my first experience of an ice-cave, it would doubtless have seemed very remarkable, as it did to Liotir, who, by the way, had steadily disbelieved the possibility of natural ice in summer except in the glaciers; but as I had now seen so many, several of them much more wonderful than this, I did not care to stay longer than was absolutely necessary for measurements and investigation. Besides, the food of Dauphiné rather takes the energy and love of adventure out of an unaccustomed visitor.
