A day or two later, having meanwhile given serious thought to the whole problem of ventilation, I decided to change the position of the ventilator pipe in the center of the room. This, it will be recalled, was a U-shaped duct, one arm of which passed from a point three feet or so above the surface, down the outside of the hut, swung under the floor, and discharged the gravity-borne, fresh air into the shack through a riser housed in a tall wooden pillar extending nearly to the ceiling. Although the arrangement had promised well, a month's trial had convinced me that it ought to be changed. For one thing, the pillar was always in the way. It stood right in the middle of the shack. If I collided with it once, I collided with it a hundred times. That, however, was only an inconvenience. My real objection was that the apparatus was failing to do its job. Mornings, the cold in the room lay like a congealed liquid. By midafternoon, when the stove was running hot, the air around my head would turn warm, though the floor and the corners stayed icy. A step or two carried me from equatorial warmth to polar cold. I wanted a more equable distribution of temperature, if I could get it; but more than anything else I wanted plenty of air in the place.
My theory was that I could get much better circulation if I brought the outlet arm of that duct close to the stove; the vacuum effect caused by the heating of the air in the pipe would pull more air into the shack. Lacking pipe joints, and having no other tools than a hammer, saw, and wrench, I solved the problem, finally, in a simple way. After taking down the wooden pillar and pipe, I sawed off seven inches of the wooden housing, and nailed it over the vent in the middle of the floor. Over this I nailed a piece of heavy canvas, thus making a box. Then I let into the side of it a piece of pipe, which ran across the floor to the foot of the bunk. Here an empty five-gallon gasoline tin, pierced through one side and the top, was made to serve as a second joint. Into the top of the can I fitted a stand of pipe and leaned the top part of it against the horizontal section of the stovepipe near the ceiling.
I didn't finish until 3 o'clock in the morning; and, while the result was hardly a new advance in the technics of air conditioning, an improvement in my ventilation was noticeable. A piece of tissue paper held over the outlet fluttered convincingly. And now that the awkward pillar had been eliminated from the middle of the room, the shack seemed twice as large. However, the dispensation was limited; for, instead of bumping against the pipe, I was now tripping over it; but the increased elbow room was adequate compensation. Next morning, when I got up, the inside temperature was 30 degrees below zero. The new arrangement was working quite nicely indeed.
Although the day was gone, the twilight lingered in the sun's wake. At noon the northern horizon continued to erupt with explosive reds and yellows and greens. There were still several hours on either side of noon when I could work and travel on the Barrier without a light. But the mornings and afternoons were dark as night; and I found that my routine was being regulated imperceptibly by the darkness, even as the daylight had regulated it before. In addition to the weather observations I now had to make five auroral observations every day. They came at 10 o'clock in the morning, then at 1 o'clock, 4 o'clock, 7 o'clock, and the last at 10 o'clock. The aurora occurs in complicated patterns, called rays, arcs, curtains, bands, and coronas. Standing at the hatch, I would identify the structure, and note other relevant information, such as the bearing and estimated altitude of the center and the termini. These data were entered in a special book; and the auroral observations, like the meteorological observations, were timed to coincide with simultaneous observations at Little America to make for true correlations later on. A day broken up in this wise could never be a spacious day. Until I became used to it, my life seemed to be made up of busy, unrelated little fragments which I seldom succeeded in piecing together.
Now, I had always been a somewhat casual person, governed by moods as often as by necessities, and given to working at odd hours. My footless habits were practically ruinous to those who had to live with me. An explorer's home is his office, recruiting station, headquarters, and main cache. Mine was the mobilization and demobilization point of all my expeditions. The telephone used to ring at all hours. People tramped in and out as if it were a public place. Mukluks and sleeping bags and pemmican samples and sun compasses cluttered up the living room, the bedrooms, the closets — every nook, in fact, where I could find room to dump them. And meals were never on time because Daddy was (1) on the long-distance telephone; or (2) spinning yarns with an old shipmate; or (3) preparing a talk; or (4) getting ready to go off somewhere. Remembering the way it all was, I still wonder how my wife ever succeeded in bringing up four such splendid children as ours, wise each in his or her way, and each one as orderly as Father almost never was. Certainly it has been done in spite of the example set by that haphazard man who came and went at 9 Brimmer Street. However, I have often explained to the children how lucky they were to have in their mother one parent who offered a perfect example of what to do, and in their father another who was an example of what not to do.
Out at Advance Base I made a heroic effort to mend my ways. Not from conscience but from necessity. From the beginning I had recognized that an orderly, harmonious routine was the only lasting defense against my special circumstances. The brain-cracking loneliness of solitary confinement is the loneliness of a futile routine. I tried to keep my days crowded; and yet, at the same time, I, the most unsystematic of mortals, endeavored to be systematic. At night, before blowing out the lantern, I formed the habit of blocking out the morrow's work. Once the tunnels were cleared up and the shack was made shipshape, I could afford to be more leisurely. In drafting the day's agenda, I seldom set up any special objectives. It was a case of assigning myself an hour, say, to the Escape Tunnel, half an hour to leveling drift, an hour to straightening up the fuel drums, an hour to cutting bookshelves in the walls of the food tunnel, and two hours to renewing a broken bridge in the man-hauling sledge.
If the time was not sufficient, well and good; let the job be resumed another day. It was wonderful to be able to dole out time in this way. It brought me an extraordinary sense of command over myself and simultaneously freighted my simplest doings with significance. Without that or an equivalent, the days would have been without purpose; and without purpose they would have ended, as such days always end, in disintegration.
April 21
The morning is the hardest time. It is hard enough anywhere for a man to begin the day's work in darkness; where I am it is doubly difficult. One may be a long time realizing it, but cold and darkness deplete the body gradually; the mind turns sluggish; and the nervous system slows up in its responses. This morning I had to admit to myself that I was lonely. Try as I may, I find I can't take my loneliness casually; it is too big. But I must not dwell on it. Otherwise I am undone.
At home I usually awaken instantly, in full possession of my faculties. But that's not the case here. It takes me some minutes to collect my wits; I seem to be groping in cold reaches of interstellar space, lost and bewildered. The room is a non-dimensional darkness, without shadow or substance; even after all these days I sometimes ask myself: Where am I? What am I doing here? I discover myself straining, as if trying to hear something in a place where no sound could possibly exist. Ah, yes. Tick-tick, tick-tick-tick, tick. The busy, friendly voices of the register and thermograph on the shelves, each distinct and dramatic — sounds I can understand and follow, even as a mariner emerging from the darkness of the boundless ocean can recognize and follow a coast by the bell buoys offshore.
