At ten minutes of two we were roped together and feeling our way carefully in the cut steps on a glacier so steep that, standing erect, one could put his hand upon it. We were on this nearly an hour. Just as we left it for the rocks a great noise above, and a little to the south, attracted attention. A vast mass of stone had detached itself from the overhanging cliff at the top, and falling on the steep slope had broken into a hundred pieces. These went bounding down the side in long leaps. Wherever one struck a cloud of powdered stone leaped into the air, till the whole mountain side smoked and thundered with the grand cannonade. The omen augured to me that the mountain was going to do its best for our reception and entertainment. Fortunately these rock avalanches occur on the steep, unapproachable sides, and not at the angle where men climb. How the mountain grew upon us as we clung to its sides! When the great objects below had changed to littleness the heights above seemed greater than ever. At half past four we came to a perpendicular height of twenty feet, with a slight slope above. Down this precipice hung a rope; there was also an occasional projection of an inch or two of stone for the mailed foot. At the top, on a little shelf, under hundreds of feet of overhanging rock, some stones had been built round and over a little space for passing the night. The rude cabin occupied all the width of the shelf, so that passing to its other end there was not room to walk without holding on by one's hands in the crevices of the wall. We were now at home; had taken nine hours to do what could be done in eight. What an eyrie in which to sleep! Below us was a sheer descent, of a thousand or two feet, to the glacier. Above us towered the crest of the mountain, seemingly higher than ever. The sharp shadow of the lofty pyramid lengthened toward Monte Rosa. Italy lifted up its mountains tipped with sunshine to cheer us. The Obernese Alps, beyond the Rhone, answered with numerous torches to light us to our sleep. According to prearrangement, at eight o'clock we kindled a light on our crag to tell our friends in Zermatt that we had accomplished the first stage of our journey. They answered instantly with a cheery blaze, and we lay down to sleep. When four of us lay together I was so crowded against the wall that I thought if it should give way I could fall two thousand feet out of bed without possibility of stopping on the way. The ice was two feet thick on the floor, and by reason of the scarcity of bedding I was reminded of the damp, chilly sheets of some unaired guest-chambers. I do not think I slept a moment, but I passed the night in a most happy, thoughtful, and exultant frame of mind.
