rocks, from which the terminal wall of the cave sprang up. The
effect of the view from this point, as we looked up the long slope of
ice to where the ladders and a small piece of sky were visible, was most
striking. The accompanying engraving is from a sketch which attempts to
represent it; the reality is much less prim, and much more full of
beautiful detail, but still the engraving gives a fair idea of the
general appearance of the cave.

While I was occupied in making sketches and measurements, Mignot was
engaged in chopping discontentedly at the floor, in two or three
different places. At length he seemed to find a place to his mind, and
chopped perseveringly till his axe went through, and then he suggested
that we should follow. The hole was not tempting. It opened into the
blackest possible darkness, and Mignot thrust his legs through,
feeling for a foothold, which, by lowering himself almost to his
armpits, he soon discovered: the foothold, however, proved to be a
loose stone, which gave way under him and bounded down, apparently
over an incline of like stones, to a distance which sounded very
alarming. But he would not give in, and at length, descending still
further by means of the snow in which the hole was made, he was
rewarded by finding a solid block which bore his weight, and he
speedily disappeared altogether, summoning me to follow. I proposed to
light a candle first, not caring to go through such a hole, in such a
floor, into no one knew what; but he was so very peremptory, evidently
thinking that if he had gone through without a pioneering candle his
monsieur might do the same, that there was nothing for it but to obey.
The hole was very near the junction of the floor with the slope of
stones where the floor terminated, and the space between the hole and
the slope seemed to be filled up with a confused mass of snow and ice,
in which the snow largely predominated; so that there was good hold
for hands and feet in passing down to the stones, which might be about
7 feet below the upper surface of the floor. Here we crouched in the
darkness, with our faces turned away from the presumed slope of
stones, till a light was struck. The accomplice did not find it in the
bond that he should go down, and he preferred to reserve his energies
for his own peculiar glaciere.

As soon as the candle had mastered a portion of the darkness, we found
that we were
