thing that could be seen from our gîte. Monte Viso, a hundred miles off, was clear, and the sun set gorgeously behind the range of Mont Blanc. We passed the night comfortably—even luxuriously—in our blanket-bags, but there was little chance of sleeping, between the noise of the wind, of the thunder, and of the falling-rocks. I forgave the thunder for the sake of the lightning. A more splendid spectacle than its illumination of the Matterhorn crags I do not expect to see.[1]
The greatest rock-falls always seemed to occur in the night, between midnight and daybreak. This was noticeable on each of the seven nights which I passed upon the south-west ridge, at heights varying from 11,800 to 13,000 feet.
I may be wrong in supposing that the falls in the night are greater than those in the daytime, since sound causes much more effect during darkness than when the cause of its production is seen. Even a sigh may be terrible in the stillness of the night. In the daytime one's attention is probably divided between the sound and the motion of rocks which fall; or it may be concentrated on other matters. But it is certain that the greatest of the falls which happened during the night took place after midnight, and this I connect with the fact that the maximum of cold during any twenty-four hours very commonly occurs between midnight and dawn.
We turned out at 3.30 a.m. on the 11th, and were dismayed to find that it still continued to snow. At 9 a.m. the snow ceased to fall, and the sun showed itself feebly, so we packed up our baggage, and set out to try to get upon "the shoulder." We struggled upwards until eleven o'clock, and then it commenced to snow again. We held a council; the opinions expressed at it were unanimous against advancing, and I decided to retreat. For we had risen less than 300 feet in the past two hours, and had not even arrived at the rope which Tyndall's party left behind, attached to the rocks,
