Every day, between 12 o'clock and 1 o'clock, I changed the recording sheets on the register and the inside thermograph. The pens and the pads supplying them always needed inking, and the thermograph clock had to be wound. Mondays I performed the same service for the outside thermograph and the barograph.

April came in on Easter Sunday. It came in blowing and snowing, bringing a southeaster which laced the air with drift but shot the temperature up from -48 degrees to -25 degrees before the day was done. Not a pleasant day, but decidedly on the warmish side, after March's cold. In the morning at 10 o'clock, I attempted the first radio contact with Little America. Considering my inexperience, the fact that it was successful — at least in that I managed to make myself understood — set me up enormously. For, if any contingency truly disturbed me, it was the chance of my losing radio contact with Little America. Not on my account, but on the expedition's account generally. In spite of the orders I had given and the promises made to respect them, I knew in my own heart that both might be ignored if Little America was out of touch with me for long. And, if Little America chose to act, an appalling tragedy might easily result. Realizing how much depended upon my ability to hold communication, I was oppressed by the thought I might fail through sheer ignorance. Dyer had shown me how to make repairs, and Waite had coached me in operating the set; but, whenever I looked at the complications of tubes, switches, and coils, my heart misgave me. I scarcely knew the Morse code. Fortunately Little America could talk to me by radio telephone. So I wasn't obliged to decipher hot outpourings of dots and dashes from skillful operators. But reply I must in dots and dashes, and that I doubted I could do.
Two hours before the schedule I made ready. The gasoline-driven generator which powered the transmitter stood in an alcove, about halfway down the food tunnel, from which a six-inch ventilator pipe went through to the surface. Of course, it couldn't be run in the shack on account of the fumes. To drive the chill out of the metal I brought the engine indoors and put it on the chair, close to the stove. There the engine stood for an hour and a half, dripping with moisture. Then I filled the tank with a mixture of gasoline and lubricating oil, hurried the engine back to the alcove and tried to start it before the metal chilled. I cranked it after the fashion of an outboard motor, using a cord with a wooden handle at one end and a knot at the other. The knot slipped into a notch in the small flywheel; and, after taking a couple of turns around the wheel, I'd pull hard, spinning the engine. That morning it started off on the first spin. By then it was nearly 10 o'clock, and I had to leg it back into the hut to meet the schedule on time.
The receiver was tuned for 100 meters. The tubes glowed when I threw the switch, and the dial readings showed that everything was as it should be. I waited five minutes or so for the tubes to warm up. Precisely at 10 o'clock, as I clamped on the headphones, I heard Dyer's clear, modulated voice saying: «KFZ calling KFY. This is KFZ calling KFY. Will you please come in?» Excited, as nervous as a student pilot on his first solo hop, I cut in the transmitter and keyed: «OK, KFZ. All well. How are trail parties?» Or at least that was what I tried to spell out. The dot-dash equivalents were as confusing and unfamiliar as Arabic, and in the middle of a sentence I forgot completely what I was supposed to be sending.
Nevertheless, Charles Murphy came on a moment later with the news that both the Advance Base crew and Innes-Taylor's party were safely at Little America. «All hands are well,» he continued. After a few more remarks I heard him say, «Is everything all right with you?»
I was encouraged to make a more elaborate answer. «Great, working hard. Wind here thirty miles. Snowing. Think blow coming.»
Murphy chuckled, «I think John got most of that. No snow here as yet, but an easterly is making with lots of drift.»
The contact lasted only twenty minutes. The schedule days were confirmed: Sundays, Tuesdays, and Thursdays, at 10 o'clock, with daily emergency schedules to take effect at the same hour whenever my regular schedule was missed. Just before we signed off, Charlie said, «Dyer rates you D minus on your debut, but I think you deserve better than that.»
To this I retorted, «Yes, world's finest radio operator south of Lat. 80 degrees.»
