Read the passage below, it is an extract from a letter written in 1899 At 1.30 we reached the glacier and put on our ropes. It wasn't really cold, though there was an icy little breath of wind. We had about three hours up very nice rock. I had been in high spirits for it was so easy, but before long my hopes were dashed! We had about two hours and a half of awfully difficult rock. There were two places where Marius literally pulled me up like a parcel. He has the strength of a bear. And it was absolutely sheer down. The first half-hour I gave myself up for lost. It didn't seem possible that I could get up all that wall without ever making a slip. You see, I had practically never been on a rock before. However, I didn't let on to Marius and presently it began to seem quite natural to be hanging by my eyelids over an abyss.
