WORST JOURNEY IN THE WORLD
gaps between the blocks. However, we felt already that nothing could drag that roof out of its packing, and subsequent events proved that we were right.
It was a bleak job for three o'clock in the morning before breakfast, and we were glad to get back to the tent and a meal, for we meant to have another go at the Emperors that day. With the first glimpse of light we were off for the rookery again.
But we now knew one or two things about that pressure which we had not known twenty-four hours ago; for instance, that there was a lot of alteration since the Discovery days and that probably the pressure was bigger. As a matter of fact it has been since proved by photographs that the ridges now ran out three-quarters 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
