Sometime afterwards I fell asleep. It was 5:30 by my wrist watch when I awakened. At that hour I had little will and less strength; but somehow I managed to chivvy myself out of the sleeping bag, into my clothes, and up the hatch. A puffy norther, freezing to the touch, surged across the Barrier; but the sky was marvelously clear. A good omen, which was substantiated by the rising barometer. Nevertheless, my heart sank when I turned the flashlight on the thermograph sheet. The temperature had taken a nose dive, dropping from -24 degrees to -46.5 degrees; and the line was still falling steeply. Although the stove was going full blast, it gave off little heat; so, for that matter did the heat pads, whose chemicals were almost exhausted.
Dyer was on the air almost at the same instant I sat down astride the transmitter's bicycle seat. «Good morning,» he said, after I acknowledged the call. «Have you the weather report ready? Haines is waiting for it.»
The weather report having been disposed of, Poulter informed me that on Haines's recommendation the start had been postponed until noon, pending another weather report from Advance Base. Although yesterday's blizzard at Little America had from all appearances blown itself out, Haines was reluctant to give an «all clear» ruling until his own upper-air balloon soundings, plus another good report from Advance Base, indicated that conditions were stabilizing. «Still, Bill says to tell you it looks pretty good — good and cold,» Poulter concluded.
That extra effort, coming before I had had time to eat or get warm, did me in for a while. In fact, I petered out while I rested. The hot milk and cereal which I had downed for breakfast came up in a retching spasm before I could reach the tunnel. It made a vile mess. I retreated to the bunk to wait for noon. The hours dragged. By the storm lantern's light I could see the thermograph trace falling, steadily falling. At noon, when I went topside for a look at the weather, the thermometer read 61 degrees below; but the wind was dying; the barometer was still going up; and the sky was clear and, in the north, suffused by a rosy, promising glow.
«Haines is satisfied,» Murphy said after I had passed this on. «It's getting cold here, too — only 14 degrees below yesterday, but -40 degrees today. However, clear weather is what Poulter wants; and evidently he's getting it. He says he will shove off in an hour.»
«Tell him be careful.»
«Yes, indeed. Sorry to be so curt. See you at 4.»
I hesitate to describe the events that followed. No doomed man pacing a cell in the hope of an eleventh-hour reprieve can possibly have endured more that I endured; for, besides my own skin to think about, I had the lives of five other men on my conscience. All the pre-start excitement drained out of me. In its place came remorse over having countenanced the trip in the first place and fear as to the consequences. I could neither lie quiet nor sit still. Once, for no reason at all, I climbed the hatch and stared aloft, as if the sky must in some manner testify to the inception of an heroic act. But there was only the moon, veiled by ice crystals, so cold that it chilled you to look at it.
The temperature worked to 62 degrees below. I now prepared for my beacon lights. In the box of navigation gear were eight or nine magnesium flares, fixed to wooden handles, which burn with a vivid light. I counted out six, which I cached in a small box at the foot of the ladder. Rummaging around, I found two spare ventilator-pipe sections, about three feet long. These I hauled to the surface on a line; then I stood them upright on the snow and laid a plank across. This gave me a work bench, and a higher platform for my gasoline pots. My idea was to stand the gasoline in open cans on the bench and fire them one after the other.
I was interrupted in the midst of these preparations by the 4 p.m. schedule. Dyer was too busy for more than a word. Poulter, he said, had put out from Little America at 2:30 o'clock and had just reported that he was four miles out, approaching the edge of Amundsen Arm. Before supper I managed to fill with gasoline four empty tins, none more than a gallon, three of which I hoisted to the surface. At 8 o'clock the thermograph read -65 degrees. Little America advised: «They've crossed Amundsen Arm and are now on high Barrier, about eleven miles south, preparing to square away on the Southern Trail. Evidently they are having trouble picking up the flags. See you at midnight.»
Cold. The red trace worked lower. Christmas, is it to be their bad luck to choose the year's bitterest temperatures to come here? I exclaimed to myself. Dyer had told me the wave lengths on which he would exchange hourly reports with the tractor. I tried to overhear; but, while I caught the bustle of traffic, the sending was much too fast for me to handle. Approaching midnight, the wind trace on the register testified that the wind, after dallying briefly in the west, was again haunting the northwest at whisper strength; the barometer was still rising, which was a good sign; but in the last hour the temperature had twitched 5 degrees downward to 75 degrees below zero, the coldest reading of the year, and colder by over 2 degrees than the coldest temperature ever registered at Little America. Although I knew they would have warmer temperatures than these, nonetheless, the thought of five men on the Barrier, trying to keep themselves and a motor alive in such temperatures, drove me frantic.
At midnight Murphy sounded discouraged. «We've just heard from Poulter,» he said. «The tractor is now seventeen miles south of us. They've slowed up but are still under way.»
I spelled out, «All OK?»
The voice in the earphones seemed to come from very far off as Murphy repeated slowly: «Evidently not. It's snowing hard where they are, though clear here. Poulter says the visibility is zero. Apparently the flags are all snowed under. Only two inches of bunting show above the surface. So they're running on compass courses from flag to flag. When they miss one, they keep circling until they find it. And, because some of the flags have been blown down, leaving gaps in the line, they are necessarily making slow progress.»
On account of the faults in my receiver, I had to make Murphy repeat two or three times; but this was the gist of his report. In the face of it I had no right to keep hoping. For I had traveled enough in the polar regions to appreciate what was happening in the oceanic darkness to the north. I could visualize Poulter sitting astride the engine hood, holding the searchlight in his hand, trying to pick up shreds of cloth no bigger than a man's hand, each spaced 293 yards from the next. He knew the courses steered by Innes-Taylor, who had marked the trail nearly five months earlier; but this information was of small help to him in running from flag to flag. Dog teams never travel in a straight line; rather, they make good their direction in short zigzags, first to one side and then to the other. The flags might therefore be twenty yards or more to the right or left of the true course. Hence, this business of circling after the tractor crew had run out their distance by the speedometer without fetching a marker.
«Dick, there's no sense in your staying up all night,» Little America advised. «We'll be in touch with Poulter. Suppose we meet you again at 8 o'clock in the morning.»
