It was a lucky piece of sagacity in us that we concluded to stop a man whom we met and get a light for our pipes from him instead of continuing the climb to that lantern to get a light, as had been our purpose. The man said that that lantern was on the Grands Mulets, some sixty-five hundred feet above the valley! I know by our Riffelberg experience, that it would have taken us a good part of a week to go up there. I would sooner not smoke at all, than take all that trouble for a light.
Even in the daytime the foreshadowing effect of this mountain's close proximity creates curious deceptions. For instance, one sees with the naked eye a cabin up there beside the glacier, and a little above and beyond he sees the spot where that red light was located; he thinks he could throw a stone from the one place to the other. But he couldn't, for the difference between the two altitudes is more than three thousand feet. It looks impossible, from below, that this can be true, but it is true, nevertheless.
While strolling around, we kept the run of the moon all the time, and we still kept an eye on her after we got back to the hotel portico. I had a theory that the gravitation of refraction, being subsidiary to atmospheric compensation, the refrangibility of the earth's surface would emphasize this effect in regions where great mountain ranges occur, and possibly so even-handed impact the odic and idyllic forces together, the one upon the other, as to prevent the moon from rising higher than 12,200 feet above sea-level. This daring theory had been received with frantic scorn by some of my fellow-scientists, and with an eager silence by others. Among the former I may mention Prof. H----y; and among the latter Prof. T----l. Such is professional jealousy; a scientist will never show any kindness for a theory which he did not start himself. There is no feeling of brotherhood among these people. Indeed, they always resent it when I call them brother. To show how far their ungenerosity can carry them, I will state that I offered to let Prof. H----y publish my great theory as his own discovery; I even begged him to do it; I even proposed to print it myself as his theory. Instead of thanking me, he said that if I tried to fasten that theory on him he would sue me for slander. I was going to offer it to Mr. Darwin, whom I understood to be a man without prejudices, but it occurred to me that perhaps he would not be interested in it since it did not concern heraldry.
But I am glad now, that I was forced to father my intrepid theory myself, for, on the night of which I am writing, it was triumphantly justified and established. Mont Blanc is nearly sixteen thousand feet high; he hid the moon utterly; near him is a peak which is 12,216 feet high; the moon slid along behind the pinnacles, and when she approached that one I watched her with intense interest, for my reputation as a scientist must stand or fall by its decision. I cannot describe the emotions which surged like tidal waves through my breast when I saw the moon glide behind that lofty needle and pass it by without exposing more than two feet four inches of her upper rim above it; I was secure, then. I knew she could rise no higher, and I was right. She sailed behind all the peaks and never succeeded in hoisting her disk above a single one of them.
While the moon was behind one of those sharp fingers, its shadow was flung athwart the vacant heavens-- a long, slanting, clean-cut, dark ray--with a streaming and energetic suggestion of FORCE about it, such as the ascending jet of water from a powerful fire-engine affords. It was curious to see a good strong shadow of an earthly object cast upon so intangible a field as the atmosphere.
We went to bed, at last, and went quickly to sleep, but I woke up, after about three hours, with throbbing temples, and a head which was physically sore, outside and in. I was dazed, dreamy, wretched, seedy, unrefreshed. I recognized the occasion of all this: it was that torrent. In the mountain villages of Switzerland, and along the roads, one has always the roar of the torrent in his ears. He imagines it is music, and he thinks poetic things about it; he lies in his comfortable bed and is lulled to sleep by it.
