the sky, that it could well have passed for a setting sun. In the cold air (the temperature was 50 degrees below zero) the exhaust vapor puffed up like a smoke screen, which a gentle northerly wind fanned out until much of the eastern horizon was obscured. I went below, intending to busy myself with the wind-speed records; but the errand was a piece of self-deception which I could not quite bring off. For perhaps the only moment in my adult life I was conscious of being utterly at loose ends. The shack, which had seemed bright and cheery, now was neither. And obeying an impulse which I had no time to be ashamed of, I rushed up the hatch ladder. Just why, I don't know even now; perhaps for a last look at something alive and moving. Although the cars were by then some distance away, I could still hear the beep beep of the horns and the clatter of the treads, so clearly do sounds carry in that crystal air.
I watched until the noise died out; until the receding specks had dropped for good behind a roll in the Barrier; until only the vanishing exhalations of the vapor remained.
With that the things of the world shrank to nothing. In the southern sky, opposite the waning sun, the night, already settled over the pole, was pushing forth a bulging shadow, blue-black and threatening as a storm sky. Did I see in it the first nervous movements of the aurora australis? I couldn't be sure. A frozen nose and cheeks sent me below before I had time to find out. But, as I slid down the ladder, I was sure of something else, which gave me a bad turn; and that was that in helping the tractor men stow the sledges I had fallen and wrenched my shoulder. The right one was hurting like the devil.
In the shack I stood for a long minute, rubbing the shoulder. Bad business, I reproached myself. Here you're starting the biggest job of your life, and yet, you've blundered and crippled yourself. For things were in an awful mess. The tunnels were a jumble of boxes and fuel drums, and I should be weeks putting them straight. Doubtless they looked shipshape to the tractor men. Hardened to the fearful disorder of their vehicles, they did their house cleaning by booting anything offensive out of the way. So long as there was room to squat, they were content. Well, I couldn't live that way at Advance Base. But only one pair of shoulders was available for all the lifting and moving and shoveling; and they were 50 percent out of commission.
I couldn't just sit and mope. Using one arm as best I could, I started to clean up my own Augean Stable. Absorbed in the task, I forgot the ache in my shoulder. The hours melted away; it was past midnight before I thought of stopping. I paused only long enough to brew a pot of tea and to munch a few crackers. Although I had little to show for the day's work, I could at last move around in the tunnels without tripping over duffel bags, food tins, and bundles of bamboo marker poles. Tomorrow I would commence unpacking the books and racking the medical stores in a handy place. Later on, I would put the food and fuel tunnels in order. The main responsibility, after all, was the meteorological instruments, which, so far, were running smoothly. Every hour I took time out to inspect them, a practice I wanted to become a habit. Already I was regarding them with the warm, covert look reserved for good companions.
The day's work done, I took the luxury of a meditative inventory; and what I saw was good. The means of a secure and profound existence were all handy, in a world I could span in four strides going one way and in three strides going the other. It was not a bright world. The storm lantern hanging from a nail over my bunk burned dimly; and the gasoline pressure lamp, suspended from the ceiling, seemed to concentrate its brilliance all in one patch, making the shadows seem all the darker. But the dimness was rather to my liking. It gave depth to the room, and, somehow, made my possessions seem bigger.
My bunk, fastened to the north wall, was about three feet off the floor, with the head flush against the eastern wall. At the foot of the bunk, on a small table, was the register, a glass-enclosed mechanism of revolving drum and pens which automatically recorded wind direction and velocity as reported by the wind vane and anemometer cups to which it was electrically connected. The dry cells powering the pens and driving the drum were racked underneath. Across the room, in the southeast corner, was a triangular shelf holding the main combination radio transmitter and receiver, with a key fastened near the edge. The transmitter was a neatly constructed, 50- watt, self-excited oscillator which Dyer had assembled himself, and which was powered by a 350-watt, gasoline- driven generator weighing only 35 pounds. The receiver was a superheterodyne of standard make. Above this shelf was a smaller one holding the emergency radio equipment, consisting of two 10-watt transmitters powered by hand-cranked generators, plus two small battery receivers, each good for about a hundred hours. These were stand-by equipment. And above this shelf was a still smaller shelf holding spare parts for the radio.
The east wall, between the head of the bunk and the radio corner, was all shelves — six, to be exact. The lower ones were stocked with food, tools, books, and other odds and ends. On the top shelves were instruments and chronometers, all placed high and some wrapped in cotton. On the south wall my windproofs, fur mukluks, parka, and pants hung drying from tenpenny nails. Pushed against the middle of the same wall was a food box on which was a portable victrola in a battered green case. The table was also the family board. On the floor in the southwest corner was a box which I called the ice box, since anything put into it would stay frozen. Among other things it then contained were two Virginia hams which my mother had sent me.
The stove was a foot or so out from the west wall, about midway between the door and the triple register. It was an ordinary two-lid, coal-burning caboose stove, except that this one had been converted into an oil burner by fitting a round burner over the grate and rigging a three-gallon gravity tank to feed it. It burned Stoddard solvent, ranking midway between kerosene and gasoline among the petroleum distillates. A liquid fuel was chosen instead of coal because coal was too bulky to haul. From the stove the stack went straight up to within two feet of the ceiling, where it bent and ran along the wall before passing through a vent above the foot of the bunk. By carrying the pipe across the room this way, we thought we were providing the equivalent of a radiator; but the scheme was a clumsy makeshift. Two or three pipe sections were lost on the trail, somewhere between Little America and Advance Base; and, the only reserve sections being of a different size, we had used empty five-gallon tins as joints, cut open at the ends to fit. Ingenious as they were, the connections were scarcely air tight. This crude, inoffensive-looking heating plant held for me the power life and death. Innocent in every rude line, it would nearly kill me a few months hence. And the time would come when I should wonder how I could have been such a fool as not to see what was in plain sight for me to see.
The heating and ventilation of the shack had been a problem from the first. At Little America, where we had given the shack a six weeks' «trial run,» both Charlie Murphy and Siple had complained about being made ill by the fumes while they occupied it. This was a warning, since the shack, then above ground, was much better ventilated than it would be underground. Glad for having detected that «bug» in time, I had had the machinist make a new burner. During the month I had lived in the shack at Little America, it had worked fine. Yet, Petersen, the second night at Advance Base, had had a headache and had felt nauseated when he stayed too long inside. But, as nobody else had complained of feeling funny, I had decided that his sickness probably had come from an upset stomach. True, a queer, sickish, oil smell — the smell peculiar to any oil stove — was always in the air; and now it was somewhat more noticeable as a result of fumes seeping from the ill-fitting pipe joints. But Siple and I were pretty certain that the ventilation system would eliminate any danger from these fumes. The intake system consisted of a U-shaped pipe, of which one arm stood about three and a half feet above the shack roof. This arm came down outside the west wall, passed under the shack, and rose through a vent in the floor. The inside arm of the U, which was enclosed in a square wooden insulating pillar, rose straight in the middle of the room and opened within a foot or so of the ceiling. The idea was that the cold air, flowing into the shack under gravity, would mix with the warm air at the ceiling and circulate naturally. Otherwise it would lie stagnant on the floor. A three-and-a-half-inch galvanized pipe, cut into the roof, disposed of spent air. I had rather wanted to enlarge this exhaust hole, but didn't dare, remember that the suction effect of a gale always pulls air out of a shack, and probably would pull the noxious fumes from the stove directly into the room as well.
If this setup held the seeds of misfortune, they were not in evidence during my first day alone. On the contrary, I thought the pipe was drawing well. When I put my hand over the end, I could feel a steady flow pouring from it.
About 1 o'clock in the morning, just before turning in, I went topside for a look around. The night was spacious and fine. Numberless stars crowded the sky. I had never seen so many. You had only to reach up and fill your hands with the bright pebbles. Earlier, a monstrous red moon had climbed into the northern quadrant, but it was gone by then. The stars were everywhere. A sailor's sky, I thought, commanded by the Southern Cross and the wheeling constellations of Hydrus, Orion, and Triangulum drifting ever so slowly. It was a lovely motion to watch. And all this was mine: the stars, the constellations, even the earth as it turned on its axis. If great inward peace
