s of a mile farther into the sea than
they did ten years before. We knew also that if we entered the pressure
at the only place where the ice-cliffs came down to the level of the
Barrier, as we did yesterday, we could neither penetrate to the rookery
nor get in under the cliffs where formerly a possible way had been found.
There was only one other thing to do--to go over the cliff. And this was
what we proposed to try and do.

Now these ice-cliffs are some two hundred feet high, and I felt
uncomfortable, especially in the dark. But as we came back the day before
we had noticed at one place a break in the cliffs from which there hung a
snow-drift. It _might_ be possible to get down that drift.

And so, all harnessed to the sledge, with Bill on a long lead out in
front and Birdie and myself checking the sledge behind, we started down
the slope which ended in the cliff, which of course we could not see. We
crossed a number of small crevasses, and soon we knew we must be nearly
there. Twice we crept up to the edge of the cliff with no success, and
then we found the slope: more, we got down it without great difficulty
and it brought us out just where we wanted to be, between the land cliffs
and the pressure.

Then began the most exciting climb among the pressure that you can
imagine. At first very much as it was the day before--pulling
ourselves and one another up ridges, slithering down slopes, tumbling
into and out of crevasses and holes of all sorts, we made our way along
under the cliffs which rose higher and higher above us as we neared the
black lava precipices which form Cape Crozier itself. We straddled along
the top of a snow ridge with a razor-backed edge, balancing the sledge
between us as we wriggled: on our right was a drop of great depth with
crevasses at the bottom, on our left was a smaller drop also crevassed.
We crawled along, and I can tell you it was exciting work in the more
than half darkness. At the end was a series of slopes full of crevasses,
and finally we got right in under the rock on to moraine, and here we had
to leave the sledge.

We roped up, and started to worry along under the cliffs, which had now
changed from ice to rock, and rose 800 feet above us. The tumult of
pressure which climbed against them showed no order here. Four hundred
miles of moving ice behind it had just tossed and twisted those giant
ridges until Job himself would
