But a break came in these ideal conditions: one afternoon the sun grew vapour-veiled and up the valley from the northwest a wind frozen with miles of travel over icebound hillsides began scouting through the calm halls of the heavens. Soon it grew dusted with snow, first in small flakes driven almost horizontally before its congealing breath and then in larger tufts as of swansdown. And though all day for a fortnight before the fate of nations and life and death had seemed to me of far less importance than to get certain tracings of the skate-blades on the ice of proper shape and size, it now seemed that the one paramount consideration was to hurry back to the hotel for shelter: it was wiser to leave rocking-turns alone than to be frozen in their quest.
I had come out here with my cousin, Professor Ingram, the celebrated physiologist and Alpine climber. During the serenity of the last fortnight he had made a couple of notable winter ascents, but this morning his weather-wisdom had mistrusted the signs of the heavens, and instead of attempting the ascent of the Piz Passug he had waited to see whether his misgivings justified themselves. So there he sat now in the hall of the admirable hotel with his feet on the hot-water pipes and the latest delivery of the English post in his hands. This contained a pamphlet concerning the result of the Mount Everest expedition, of which he had just finished the perusal when I entered.
“A very interesting report,” he said, passing it to me, “and they certainly deserve to succeed next year. But who can tell, what that final six thousand feet may entail? Six thousand feet more when you have already accomplished twenty-three thousand does not seem much, but at present no one knows whether the human frame can stand exertion at such a height. It may affect not the lungs and heart only, but possibly the brain. Delirious hallucinations may occur. In fact, if I did not know better, I should have said that one such hallucination had occurred to the climbers already.”
“And what was that?” I asked.
“You will find that they thought they came across the tracks of some naked human foot at a great altitude. That looks at first sight like an hallucination. What more natural than that a brain excited and exhilarated by the extreme height should have interpreted certain marks in the snow as the footprints of a human being? Every bodily organ at these altitudes is exerting itself to the utmost to do its work, and the brain seizes on those marks in the snow and says ‘Yes, I’m all right, I’m doing my job, and I perceive marks in the snow which I affirm are human footprints.’ You know, even at this altitude, how restless and eager the brain is, how vividly, as you told me, you dream at night. Multiply that stimulus and that consequent eagerness and restlessness by three, and how natural that the brain should harbour illusions! What after all is the delirium which often accompanies high fever but the effort of the brain to do its work under the pressure of feverish conditions? It is so eager to continue perceiving that it perceives things which have no existence!”
“And yet you don’t think that these naked human footprints were illusions,” said I. “You told me you would have thought so, if you had not known better.”
He shifted in his chair and looked out of the window a moment. The air was thick now with the density of the big snowflakes that were driven along by the squealing northwest gale.
“Quite so,” he said. “In all probability the human footprints were real human footprints. I expect that they were the footprints, anyhow, of a being more nearly a man than anything else. My reason for saying so is that I know such beings exist. I have even seen quite near at hand—and I assure you I did not wish to be nearer in spite of my intense curiosity—the creature, shall we say, which would make such footprints. And if the snow was not so dense, I could show you the place where I saw him.”
He pointed straight out of the window, where across the valley lies the huge tower of the Ungeheuerhorn with the carved pinnacle of rock at the top like some gigantic rhinoceros-horn. On one side only, as I knew, was the mountain practicable, and that for none but the finest climbers; on the other three a succession of ledges and precipices rendered it unscalable. Two thousand feet of sheer rock form the tower; below are five hundred feet of fallen boulders, up to the edge of which grow dense woods of larch and pine.
“Upon the Ungeheuerhorn?” I asked.
“Yes. Up till twenty years ago it had never been ascended, and I, like several others, spent a lot of time in trying to find a route up it. My guide and I sometimes spent three nights together at the hut beside the
