This long digression has been caused by an innocent gully which I feared the reader might think was dangerous. It was an untrodden vestibule which led to a scene so wild that even the most sober description of it must seem an exaggeration. There was a change in the quality of the rock, and there was a change in the appearance of the ridge. The rocks (talcose gneiss) below this spot were singularly firm; it was rarely necessary to test one's hold; the way led over the living rock, and not up rent-off fragments. But here, all was decay and ruin. The crest of the ridge was shattered and cleft, and the feet sank in the chips which had drifted down; while above, huge blocks, hacked and carved by the hand of time, nodded to the sky, looking like the grave-stones of giants. Out of curiosity I wandered to a notch in the ridge, between two tottering piles of immense masses, which seemed to need but a few pounds on one or the other side to make them fall; so nicely poised that they would literally have rocked in the wind, for they were put in motion by a touch; and based on support so frail that I wondered they did not collapse before my eyes. In the whole range of my Alpine experience I have seen nothing more striking than this desolate, ruined, and shattered ridge at the back of the Great Tower. I have seen stranger shapes,—rocks which mimic the human form, with monstrous leering faces — and isolated pinnacles, sharper and greater than any here; but I have never seen exhibited so impressively the tremendous effects which may be produced by frost, and by the long-continued action of forces whose individual effects are imperceptible.
It is needless to say that it is impossible to climb by the crest of the ridge at this part; still one is compelled to keep near to it, for there is no other way. Generally speaking, the angles on the Matterhorn are too steep to allow the formation of considerable beds of snow, but here there is a corner which permits it to accumulate, and it is turned to gratefully, for, by its assistance, one can ascend four times as rapidly as upon the rocks.The Tower was now almost out of sight, and I looked over
