The stove was one of those excellent and economical devices perfected by the Gethenians in their millennial effort to outwit cold. Only the use of a fusion-pack as power source could improve it. Its bionic-powered battery was good for fourteen months’ continuous use, its heat output was intense, it was stove, heater, and lantern all in one, and it weighed about four pounds. We would never have got fifty miles without it. It must have cost a good deal of Estraven’s money, that money I had loftily handed over to him in Mishnory. The tent, which was made of plastics developed for weather-resistance and designed to cope with at least some of the inside water-condensation that is the plague of tents in cold weather; the pesthry-fur sleeping-bags; the clothes, skis, sledge, food-supplies, everything was of the finest make and kind, lightweight, durable, expensive. If he had gone to get more food, what was he going to get it with?
He did not return till nightfall next day. I had gone out several times on snowshoes, gathering strength and getting practice by waddling around the slopes of the snowy vale that hid our tent. I was competent on skis, but not much good on snowshoes. I dared not go far over the hilltops, lest I lose my backtrack; it was wild country, steep, full of creeks and ravines, rising fast to the cloud-haunted mountains eastward. I had time to wonder what I would do in this forsaken place if Estraven did not come back.
He came swooping over the dusky hill—he was a magnificent skier—and stopped beside me, dirty and tired and heavy-laden. He had on his back a huge sooty sack stuffed full of bundles: Father Christmas, who pops down the chimneys of old Earth. The bundles contained kadik-germ, dried breadapple, tea, and slabs of the hard, red, earthy-tasting sugar that Gethenians refine from one of their tubers.
“How did you get all this?”
“Stole it,” said the one-time Prime Minister of Karhide, holding his hands over the stove, which he had not yet turned down; he, even he, was cold. “In Turuf. Close thing.” That was all I ever learned. He was not proud of his exploit, and not able to laugh at it. Stealing is a vile crime on Winter; indeed the only man more despised than the thief is the suicide.
“We’ll use up this stuff first,” he said, as I set a pan of snow on the stove to melt. “It’s heavy.” Most of the food he had laid in previously was ‘hyperfood’ rations, a fortified, dehydrated, compressed, cubed mixture of high-energy foods—the Orgota name for it is gichy-michy, and that’s what we called it, though of course we spoke Karhidish together. We had enough of it to last us sixty days at the minimal standard ration: a pound a day apiece. After he had washed up and eaten, Estraven sat a long time by the stove that night figuring out precisely what we had and how and when we must use it. We had no scales, and he had to estimate, using a pound box of gichy-michy as standard. He knew, as do many Gethenians, the caloric and nutritive value of each food; he knew his own requirements under various conditions, and how to estimate mine pretty closely. Such knowledge has high survival-value, on Winter.
When at last he had got our rations planned out, he rolled over onto his bag and went to sleep. During the night I heard him talking numbers out of his dreams: weights, days, distances…
We had, very roughly, eight hundred miles to go. The first hundred would be north or northeast, going through the forest and across the northernmost spurs of the Sembensyen range to the great glacier, the ice-sheet that covers the double-lobed Great Continent everywhere north of the 45th parallel, and in places dips down almost to the 35th. One of these southward extensions is in the region of the Fire-Hills, the last peaks of the Sembensyens, and that region was our first goal. There among the mountains, Estraven reasoned, we should be able to get onto the surface of the ice-sheet, either descending onto it from a mountain-slope or climbing up to it on the slope of one of its effluent glaciers. Thereafter we would travel on the Ice itself, eastward, for some six hundred miles. Where its edge trends north again near the Bay of Guthen we would come down off it and cut southeast a last fifty or a hundred miles across the Shenshey Bogs, which by then should be ten or twenty feet deep in snow, to the Karhidish border.
