any barometer but that one.

All hands rose at two in the morning and took breakfast,
and as soon as it was light we roped ourselves together
and went at that rock. For some time we tried the hook-rope
and other means of scaling it, but without success--that is,
without perfect success. The hook caught once, and Harris
started up it hand over hand, but the hold broke and if
there had not happened to be a chaplain sitting underneath
at the time, Harris would certainly have been crippled.
As it was, it was the chaplain. He took to his crutches,
and I ordered the hook-rope to be laid aside.
It was too dangerous an implement where so many people
are standing around.

We were puzzled for a while; then somebody thought of
the ladders. One of these was leaned against the rock,
and the men went up it tied together in couples.
Another ladder was sent up for use in descending.
At the end of half an hour everybody was over, and that rock
was conquered. We gave our first grand shout of triumph.
But the joy was short-lived, for somebody asked how we were
going to get the animals over.

This was a serious difficulty; in fact, it was an impossibility.
The courage of the men began to waver immediately; once more
we were threatened with a panic. But when the danger
was most imminent, we were saved in a mysterious way.
A mule which had attracted attention from the beginning
by its disposition to experiment, tried to eat a five-pound
can of nitroglycerin. This happened right alongside
the rock. The explosion threw us all to the ground,
and covered us with dirt and debris; it frightened
us extremely, too, for the crash it made was deafening,
and the violence of the shock made the ground tremble.
However, we were grateful, for the rock was gone.
Its place was occupied by a new cellar, about thirty
feet across, by fifteen feet deep. The explosion was
heard as far as Zermatt; and an hour and a half afterward,
many citizens of that town were knocked down and quite
seriously injured by descending portions of mule meat,
frozen solid. This shows, better than any estimate
in figures, how high the experimenter went.

We had nothing to do, now, but bridge the cellar and proceed
on our way. With a cheer the men went at their work.
I attended to the engineering, myself. I appointed a strong
detail to cut down trees with ice-axes and trim them for
piers to support the bridge. This was a slow business,
for ice-axes are not good
