"I remember once, when in crossing the Tête Noire, I had turned up the valley towards Trient, I noticed a rain-cloud form on the Glacier de Trient. With a west wind, it proceeded towards the Col de Balme, being followed by a prolonged wreath of vapour, always forming exactly at the same spot over the glacier. This long, serpent-like line of cloud went on at a great rate till it reached the valley leading down from the Col de Balme, under the slate rocks of the Croix de Fer. There it turned sharp round, and came down this valley, at right angles to its former progress, and finally directly contrary to it, till it came down within five hundred feet of the village, where it disappeared; the line behind always advancing, and always disappearing at the same spot. This continued for half an hour, the long line describing the curve of a horse-shoe; always coming into existence and always vanishing at exactly the same places; traversing the space between with enormous swiftness. This cloud, ten miles off, would have looked like a perfectly motionless wreath, in the form of a horse-shoe, hanging over the hills."
