Mornings after heavy snowfall we might have to spend some while digging out the tent and sledge before we could set off. The new snow was not hard to shovel away, though it made great impressive drifts around us, who were, after all, the only impediment for hundreds of miles, the only thing sticking out above the ice.

We pulled eastward by the compass. The usual direction of the wind was north to south, off the glacier. Day after day it blew from our left as we went. The hood did not suffice against that wind, and I wore a facial mask to protect my nose and left cheek. Even so my left eye froze shut one day, and I thought I had lost the use of it: even when Estraven thawed it open with breath and tongue, I could not see with it for some while, so probably more had been frozen than the lashes. In sunlight both of us wore the Gethenian slit-screen eyeshields, and neither of us suffered any snow-blindness. We had small opportunity. The Ice, as Estraven had said, tends to hold a high-pressure zone above its central area, where thousands of square milesВ of white reflect the sunlight. We were not in this central zone, however, but at best on the edge of it, between it and the zone of turbulent, deflected, precipitation-laden storms that it sends continually to torment the subglacial lands. Wind from due north brought bare, bright weather, but from northeast or northwest it brought snow, or harrowed up dry fallen snow into blinding, biting clouds like sand or dust-storms, or else, sinking almost to nothing, crept in sinuous trails along the surface, leaving the sky white, the air white, no visible sun, no shadow: and the snow itself, the Ice, disappeared from under our feet. Around midday we would halt, and cut and set up a few blocks of ice for a protective wall if the wind was strong. We heated water to soak a cube of gichy-michy in, and drank the water hot, sometimes with a bit of sugar melted in it; harnessed up again and went on. We seldom talked while on the march or at lunch, for our lips were sore, and when one's mouth was open the cold got inside, hurting teeth and throat and lungs; it was necessary to keep the mouth closed and breathe through the nose, at least when the air was forty or fifty degrees below freezing. When it went on lower than that, the whole breathing process was further complicated by the rapid freezing of one's exhaled breath; if you didn't look out your nostrils might freeze shut, and then to keep from suffocating you would gasp in a lungful of razors.

Under certain conditions our exhalations freezing instantly made a tiny crackling noise, like distant firecrackers, and a shower of crystals: each breath a snowstorm.

We pulled till we were tired out or till it began to grow dark, halted, set up the tent, pegged down the sledge if there was threat of high wind, and settled in for the night. On a usual day we would have pulled for eleven or twelve hours, and made between twelve and eighteen miles.

It does not seem a very good rate, but then conditions were a bit adverse. The crust of the snow was seldom right for both skis and sledge-runners. When it was light and new the sledge ran through rather than over it; when it was partly hardened, the sledge would stick but we on skis would not, which meant that we were perpetually being pulled up backward with a jolt; and when it was hard it was often heaped up in long wind-waves, sastrugi, that in some places ran up to four feet high. We had to haul the sledge up and over each knife-edged or fantastically corniced top, then slide her down, and up over the next one: for they never seemed to run parallel to our course. I had imagined the Gobrin Ice Plateau to be all one sheet like a frozen pond, but there were hundreds of miles of it that were rather like an abruptly frozen, storm-raised sea.

The business of setting up camp, making everything secure, getting all the clinging snow off one's outer clothing, and so on, was trying. Sometimes it did not seem worthwhile. It was so late, so cold, one was so tired, that it would be much easier to lie down in a sleeping-bag in the lee of the sledge and not bother with the tent. I remember how clear this was to me on certain evenings, and how bitterly I resented my companion's methodical, tyrannical insistence that we do everything and do it correctly and thoroughly. I hated him at such times, with a hatred that rose straight up out of the death that lay within my spirit. I hated the harsh, intricate, obstinate demands that he made on me in the name of life. When all was done we could enter the tent, and almost at once the heat of the Chabe stove could be felt as an enveloping, protecting ambiance. A marvelous thing surrounded us: warmth. Death and cold were elsewhere, outside.

Hatred was also left outside. We ate and drank. After we ate, we talked. When the cold was extreme, even the excellent insulation of the tent could not keep it out, and we lay in our bags as close to the stove as possible. A little fur of frost gathered on the inner surface of the tent. To open the valve was to let in a draft of cold that instantly condensed, filling the tent with a swirling mist of fine snow. When there was blizzard, needles of icy air blew in through the vents, elaborately protected as they were, and an impalpable dust of snow-motes fogged the air. On those nights the storm made an incredible noise, and we could not converse by voice, unless we shouted with our heads together. On other nights it was still, with such a stillness as one imagines as existing before the stars began to form, or after everything has perished.

Within an hour after our evening meal Estraven turned the stove down, if it was feasible to do so, and turned the light-emission off. As he did so he murmured a short and charming grace of invocation, the only ritual words I had ever learned of the Handdara: “Praise then darkness and Creation unfinished,” he said, and there was darkness. We slept. In the morning it was all to do over. We did it over for fifty days. Estraven kept up his journal, though during the weeks on the Ice he seldom wrote more than a note of the weather and the distance we had come that day. Among these notes there is occasional mention of his own thoughts or of some of our conversation, but not a word concerning the profounder conversation between us which occupied our rest between dinner and sleep on many nights of the first month on the Ice, while we still had enough energy to talk, and on certain days that we spent storm-bound in the tent. I told him that I was not forbidden, but not expected, to use paraverbal speech on a non-Ally planet, and asked him to keep what he learned from his own people, at least until I could discuss what I had done with my colleagues on the ship. He assented, and kept his word. He never said or wrote anything concerning our silent conversations.

Mindspeech was the only thing I had to give Estraven, out of all my civilization, my alien reality in which he was so profoundly interested. I could talk and describe endlessly; but that was all I had to give. Indeed it may be the only important thing we have to give to Winter. But I can't say that gratitude was my motive for infringing on the Law of Cultural Embargo. I was not paying my debt to him. Such debts remain owing. Estraven and I had simply arrived at the point where we shared whatever we had that was worth sharing.

I expect it will turn out that sexual intercourse is possible between Gethenian double-sexed and Hainish-norm one-sexed human beings, though such intercourse will inevitably be sterile. It remains to be proved; Estraven and I proved nothing except perhaps a rather subtler point. The nearest to crisis that our sexual desires brought us was on a night early in the journey, our second night up on the Ice. We had spent all day struggling and back-tracking in the cut-up, crevassed area east of the Fire-Hills. We were tired that evening but elated, sure that a clear course would soon open out ahead. But after dinner Estraven grew taciturn, and cut my talk off short. I said at last after a direct rebuff, "Harth, I've said something wrong again, please tell me what it is." He was silent.
