ike a
frozen river which occupies the bed of a winding gorge
or gully between mountains. But that gives no notion
of its vastness. For it is sometimes six hundred
feet thick, and we are not accustomed to rivers six hundred
feet deep; no, our rivers are six feet, twenty feet,
and sometimes fifty feet deep; we are not quite able
to grasp so large a fact as an ice-river six hundred feet deep.

The glacier's surface is not smooth and level, but has
deep swales and swelling elevations, and sometimes has
the look of a tossing sea whose turbulent billows were
frozen hard in the instant of their most violent motion;
the glacier's surface is not a flawless mass, but is a river
with cracks or crevices, some narrow, some gaping wide.
Many a man, the victim of a slip or a misstep, has plunged
down on of these and met his death. Men have been
fished out of them alive; but it was when they did not
go to a great depth; the cold of the great depths would
quickly stupefy a man, whether he was hurt or unhurt.
These cracks do not go straight down; one can seldom see
more than twenty to forty feet down them; consequently men
who have disappeared in them have been sought for,
in the hope that they had stopped within helping distance,
whereas their case, in most instances, had really been
hopeless from the beginning.

In 1864 a party of tourists was descending Mont Blanc,
and while picking their way over one of the mighty glaciers
of that lofty region, roped together, as was proper,
a young porter disengaged himself from the line and
started across an ice-bridge which spanned a crevice.
It broke under him with a crash, and he disappeared.
The others could not see how deep he had gone, so it might
be worthwhile to try and rescue him. A brave young guide
named Michel Payot volunteered.

Two ropes were made fast to his leather belt and he bore
the end of a third one in his hand to tie to the victim
in case he found him. He was lowered into the crevice,
he descended deeper and deeper between the clear blue
walls of solid ice, he approached a bend in the crack
and disappeared under it. Down, and still down, he went,
into this profound grave; when he had reached a depth
of eighty feet he passed under another bend in the crack,
and thence descended eighty feet lower, as between
perpendicular precipices. Arrived at this stage of one
hundred and sixty feet below the surface of the glacier,
he peered through the twilight dimness and
