There was a cowhouse near the chalet, and above it, raised on pillars of
pine, and approached by a ladder, was a loft, which contained a quantity
of dry hay: this my guide shook to soften the lumps, and erected an
eminence for my head. I lay down, drawing my plaid over me, but Auer
affirmed that this would not be a sufficient protection against the
cold; he therefore piled hay upon me to the shoulders, and proposed
covering up my head also. This, however, I declined, though the biting
coldness of the air, which sometimes blew in upon us, afterwards proved
to me the wisdom of the suggestion. Having set me right, my
chamois-hunter prepared a place for himself, and soon his heavy
breathing informed me that he was in a state of bliss which I could only
envy. One by one the stars crossed the apertures in the roof. Once the
Pleiades hung above me like a cluster of gems; I tried to admire them,
but there was no fervour in my admiration. Sometimes I dozed, but
always as this was about to deepen into positive sleep it was rudely
broken by the clamour of a group of pigs which occupied the ground-floor
of our dwelling. The object of each individual of the group was to
secure for himself the maximum amount of heat, and hence the outside
members were incessantly trying to become inside ones. It was the
struggle of radical and conservative among the pachyderms, the politics
being determined by the accident of position.

I rose at five o'clock on the 1st of September, and after a breakfast of
black bread and milk ascended the glacier as far as practicable. We once
quitted it, crossed a promontory, and descended upon one of its
branches, which was flanked by some fine old moraines. We here came upon
a group of seven marmots, which with yells of terror scattered
themselves among the rocks. The points of the glacier beyond my reach I
examined through a telescope; along the faces of the sections the lines
of stratification were clearly shown; and in many places where the mass
showed manifest signs of lateral pressure, I thought I could observe the
cleavage passing though the strata. The point, however, was too
important to rest upon an observation made from such a distance, and I
therefore abstained from mentioning it subsequently. I examined the
fissures and the veining, and noticed how the latter became most perfect
in places where the pressure was greatest. The effect of _oblique_
pressure was also finely shown: at one place the thrust of the
descending glacier was opposed by the resistance offered by the side of
the valley, the direction of the force being oblique to the side; the
consequence was a structure nearly parallel to the valley, and
consequently oblique to the thrust which I believe to be its cause.
