that night in May, that the concerns and practices of the outer world had not intruded into my existence. That was proved by the weeks of utter tranquillity. It was also true, as I had concluded, that the way to keep them from intruding was through the censorship and control of the mind. But beyond these was a truth which that night I did not recognize; and this truth was that the whole complex nervous-muscular mechanism which is the body was waiting, as if with bated breath, for the intrusion of familiar stimuli from the outside world, and could not comprehend why they were denied.
A man can isolate himself from habits and conveniences — deliberately, as I have done; or accidentally, as a shipwrecked sailor might — and force his mind to forget. But the body is not so easily sidetracked. It keeps on remembering. Habit has set up in the core of the being a system of automatic physio-chemical actions and reactions which insist upon replenishment. That is where the conflict arises. I don't think that a man can do without sounds and smells and noises and touch, any more than he can do without phosphorus and calcium. That is, in general, what I meant by the vague term «evenness.»
So I learned at Latitude 80 degrees 08' South. It was exhilarating to stand on the Barrier and contemplate the sky and luxuriate in a beauty I did not aspire to possess. In the presence of such beauty we are lifted above natural crassness. And it was a fine thing, too, to surrender to the illusion of intellectual disembodiment, to feel the mind go voyaging through space as smoothly and felicitously as it passes through the objects of its reflections. The body stood still, but the mind was free. It could travel the universe with the audacious mobility of a Wellsian time-space machine.
The senses were isolated in soundless dark; so, for that matter, was the mind; but one was stayed, while the other possessed the flight of a falcon; and the free choice and opportunity of the one everlastingly emphasized the poverty of the other. From the depth of my being would sometimes surge a fierce desire to be projected spectacularly into the living warmths and movements the mind revisited. Usually the desire had no special focus. It sought no single thing. Rather it darted and wavered over a panorama of human aspects — my family at dinner time, the sound of voices in a downstairs room, the cool feeling of rain.
Small matters, all of them; not realities but only the manifestations of reality. Yet, they and a thousand other remembrances of like substance assailed me at night. Not with the calm, revivifying strength of treasured memories; but bitterly and provokingly, as if they were fragments of something vast and not wholly recognizable which I had lost forever. This was the basis of my mood that night in May. Like fingers plucking at a counterpane, my thoughts moved through the days and nights of an existence that seemed to be irrevocably gone. In that mood I had walked before; I would walk like that again; and the glowing tranquillity built up in the afternoon would go out like a spent rocket.
Nevertheless, I practiced my preachments of a disciplined mind. Or perhaps discipline isn't exactly the right word; for what I did, or tried to do, was to focus my thinking on healthy, constructive images and concepts and thus crowd out the unhealthy ones. I built a wall between myself and the past in an effort to extract every ounce of diversion and creativeness inherent in my immediate surroundings. Every day I experimented with new schemes for increasing the content of the hours. «A grateful environment,» according to Santayana, «is a substitute for happiness,» for it can stimulate us from without just as good works can stimulate us from within. My environment was intrinsically treacherous and difficult, but I saw ways to make it agreeable. I tried to cook more rapidly, take weather and auroral observations more expertly, and do routine things systematically. Full mastery of the impinging moment was my goal. I lengthened my walks and did more reading, and kept my thoughts upon an impersonal plane. In other worlds, I tried resolutely to attend to my business.
All the while I experimented steadily with cold weather clothing. Inside the shack my usual outfit consisted of a thick woolen shirt, breeches, and underwear (medium weight); plus two pairs of woolen socks (one pair heavy, the other medium); plus a pair of homemade canvas boots, which were soled with thin strips of hairless sealskin, lined with a half-inch thickness of felt, and secured to the ankles by means of leather tongs fastened to the soles. The feet are most vulnerable to cold. They feel chilly sooner and stay that way longer than any other part of the body. This is partly because the circulation in the feet is not so good as in the rest of the body and because the cold from the snow gets to them from conduction and causes condensation. The permeability of canvas was a partial solution to the second difficulty. By making the boots two inches longer and half again as wide as ordinary shoes, I assisted the circulation. The boots were about as handsome as potato sacks, but they worked very well indeed. Whenever I had been a considerable time in the cold, I always changed my socks and inner liners and let the wet ones dry on the stove. The inner soles of my boots were coated with a layer of ice that never thawed. Cold was nothing new to me; and experience had taught me that the secret of protection is not so much the quantity or weight of the clothes as it is the size and quality and, above all, the way they are worn and cared for.
After I'd been at Advance Base a little while I could tell, from a glance at the thermograph, exactly what clothing I would need topside. If it were a matter of taking a quick observation, I'd just slip on a canvas windbreaker, mittens, and a woolen cap that pulled down over the ears. If I had shoveling to do, I'd substitute a helmet for the cap, and add windproof socks, pants, and parka. Walking, I'd wear a woolen parka under the windproofs, which are nothing more mysterious than fine-spun unbleached cotton blouses and pants, made of material no heavier than ordinary sheeting. I've felt wind cut though half an inch of wool as if it were nothing at all; whereas, paper-thin windproofs, closed at the ankles, chin, and waist with draw strings or elastics, were scarcely penetrated. The ideal material is not completely windproof; but lets enough air through to prevent moisture from collecting. At 65 degrees below zero, I usually wore a mask. A simple thing, it consisted of a wire framework overlaid with windproof cloth. Two funnels led to the nose and mouth, and oval slits allowed me to see. I'd breathe in through the nose funnel, and out through the mouth funnel; and, when the latter clogged with ice from the breath's freezing, as it would in short order, I brushed it out with a mitten. On the very cold days, if I had to be out two hours or more, I usually wore my fur outfit (pants, parka, mittens, and mukluks), which was made of reindeer skin, the lightest and most flexible of the warm furs. Thus protected, I could walk through my own inhospitable medium as well insulated as a diver moving through his.
Thus in May, as in April, I never really lacked for something to do. For all the hush and evenness and the slow pulse of the night, my existence was anything but static. I was the inspector of snowstorms and the aurora, the night watchman, and father confessor to myself. Something was always happening, for better or worse. For example, the Tuesday radio schedule with Little America was eliminated, to save gasoline; while this left a blank spot in the hours, the remaining two schedules in turn became more animated. There was always a message from the family in our own private code, which Dyer read with a gracious and unflagging courtesy: «A as in Arthur, L as in laughter, C as in ceiling. .» I can still hear him going on. Sometimes there were messages from friends. One message came from my old friend Franklin D. Roosevelt in the White House, saying that he hoped that «the night was not too cold or the wind too strong for an occasional promenade in the dark.» And almost always Poulter, or Rawson (now fully recovered), or Siple, or Noville, or Haines, or Innes-Taylor entered into the conversation to discuss an expedition problem or merely pass the time of day.
When I gained in one direction, I seemed to lose in another. Just when I was congratulating myself on having mastered the job of weather observer, the outside thermograph began to act up. A devilish contrivance, it occupied the instrument shelter topside, where hoarfrost settled on the trace, the pen, the drum, and even the workings. On the one occasion I brought the instrument into the shack to change the sheet and make an adjustment, the difference in temperature coated the metal with rime and stopped it dead. Thereafter I had no choice but to make the adjustments in the chill of the tunnel, with no protection for my hands except thin silk gloves; even those seemed infernally clumsy when I had to deal with the speed regulator, which must have been invented for the specific purpose of plaguing weather men.
Thus, even in the heart of the Ross Ice Barrier a solitary man had plenty to occupy him. Thus in the diary: '. . I got Canfield twice tonight — extraordinary! The only games I played, too.» And again: '. . One of my favorite records is 'Home on the Range.' It's the second song I've ever learned to sing. (The other was 'Carry Me Back To Old Virginny,' and even that I never dared to sing except in the cockpit of an airplane, where nobody could hear me.) And tonight I sang while washing the dishes. Solitude hasn't mellowed my voice any, but I had great fun. A gala evening, in fact.» The diary became more than a record; it became a means to think out loud. This was a pleasant way of filling the last hour; also, it helped to stabilize my philosophy. For example:
May 9
. . I have been persistent in my effort to eliminate the after-supper periods of depression. Until tonight my mood has been progressively better; now I am despondent again. Reason tells me that I have no right to be
