«Ask cook,» I spelled out laboriously.

«Dick, if you were starving to death,» my friend replied, «I still wouldn't trust that cleaver-wielding Marine.»

«Ask somebody,» I persisted.

«I'll tell you what,» said Charlie. «I'll send a message to Oscar of the Waldorf. In a serious matter like this, we don't want to take any chances.» [Fourteen days later, as he had promised, Charlie joyfully read a treatise by Oscar himself, the gist of which was buttering the pan. I gave up then, and resigned myself to continuing with the chisel.]

Another important event occurred today. The sun departed for good. It peeped above the horizon at noon, and with that hasty gesture set for the last time. I am feeling no particular reaction over the loss of the sun — not even envy for the men at Little America, who have an appreciably shorter winter night. Wondering why, I concluded that the long period of preparation — the lingering twilight, the lengthening nights — had put me in the mood for the change. If you hadn't lost the sun, I told myself, you would have had something serious to think about, since that would mean that the earth's axis was pointing the wrong way, and the entire solar system was running amok.

April 18

Worked topside several hours today, leveling snow and getting rid of snow blocks from the Escape Tunnel. Slipped once and fell heavily on the bad shoulder; it hurt like the deuce. I was puffing a bit while I worked and apparently got a touch of frost in the lungs, because tonight, when I breathe, I noticed a burning sensation. The temperature was 60 degrees below. My lantern froze and went out when I went topside on the last inspection trip. . This morning I found more ice in the stovepipe. I'll have to do something about that. The ice was incredibly hard. I was a long time breaking it out.

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.
