Thus the coming of the polar night is not the spectacular rush that some imagine it to be. The day is not abruptly walled off; the night does not drop suddenly. Rather, the effect is a gradual accumulation, like that of an infinitely prolonged tide. Each day the darkness, which is the tide, washes in a little farther and stays a little longer; each time the day, which is a beach, contracts a little more, until at last it is covered. The onlooker is not conscious of haste. On the contrary, he is sensible of something of incalculable importance being accomplished with timeless patience. The going of the day is a gradual process, modulated by the intervention of twilight. You look up, and it is gone. But not completely. Long after the horizon has interposed itself, the sun continues to cast up a pale and dwindling imitation of the day. You can trace its progress by the glow thrown up as it makes its round just below the horizon.
These are the best times, the times when neglected senses expand to an exquisite sensitivity. You stand on the Barrier, and simply look and listen and feel. The morning may be compounded of an unfathomable, tantalizing fog in which you stumble over sastrugi you can't see, and detour past obstructions that don't exist, and take your bearings from tiny bamboo markers that loom as big as telephone poles and hang suspended in space. On such a day, I could swear that the instrument shelter was as big as an ocean liner. On one such day I saw the blank northeastern sky become filled with the most magnificent Barrier coast I have ever seen, true in every line and faced with cliffs several thousand feet tall. A mirage, of course. Yet a man who had never seen such things would have taken oath that it was real. The afternoon may be so clear that you dare not make a sound, lest it fall in pieces. And on such a day I have seen the sky shatter like a broken goblet, and dissolve into iridescent tipsy fragments — ice crystals falling across the face of the sun. And once in the golden downpour a slender column of platinum leaped up from the horizon, clean through the sun's core; a second luminous shadow formed horizontally through the sun, making a perfect cross. Presently two miniature suns, green and yellow in color, flipped simultaneously to the ends of each arm. These are parhelia, the most dramatic of all refraction phenomena; nothing is lovelier.
April 14
. . Took my daily walk at 4 p.m. today, in 89 degrees of frost. The sun had dropped below the horizon, and a blue — of a richness I've never seen anywhere else — flooded in, extinguishing all but the dying embers of the sunset.
Due west, halfway to the zenith, Venus was an unblinking diamond; and opposite her, in the eastern sky, was a brilliant twinkling star set off exquisitely, as was Venus, in the sea of blue. In the northeast a silver-green-serpentine aurora pulsed and quivered gently. In places the Barrier's whiteness had the appearance of dull platinum. It was all delicate and illusive. The colors were subdued and not numerous; the jewels few; the setting simple. But the way these things went together showed a master's touch.
I paused to listen to the silence. My breath, crystallized as it passed my cheeks, drifted on a breeze gentler than a whisper. The wind vane pointed toward the South Pole. Presently the wind cups ceased their gentle turning as the cold killed the breeze. My frozen breath hung like a cloud overhead.
The day was dying, the night being born — but with great peace. Here were the imponderable processes and forces of the cosmos, harmonious and soundless. Harmony, that was it! That was what came out of the silence — a gentle rhythm, the strain of a perfect chord, the music of the spheres, perhaps.
It was enough to catch that rhythm, momentarily to be myself a part of it. In that instant I could feel no doubt of man's oneness with the universe. The conviction came that the rhythm was too orderly, too harmonious, too perfect to be a product of blind chance — that, therefore, there must be purpose in the whole and that man was part of that whole and not an accidental offshoot. It was a feeling that transcended reason; that went to the heart of man's despair and found it groundless. The universe was a cosmos, not a chaos; man was rightfully a part of that cosmos as were the day and night.
