changed their aspect, becoming littered and loose; and lowered and sullen skies, where clouds had become thick and dark â and then the snows came, showers and squalls of snow, and after that storms that raged a day, and then days at a time. Everything beyond our wall was white, and the new animals came crowding down towards us, their coats dragging with snow, their eyes looking sullenly out from the snow on their faces. But the snows melted, leaving the greys and the browns, and then came again â and again; and did not melt so quickly, and then did not melt at all.
Canopus said to us that we, the Representatives, should walk around our planet on the top of the wall. About fifty of us, then, set out; and Canopus came with us. The task took us almost a year. We walked into, not with, the revolving of the planet so that the sun always rose ahead of us, and we had to turn ourselves around when we wanted to see how the shadows gathered at nightfall. Because the top of the wall for the greater part of its way was so narrow, we walked no more than two or three abreast, and those at the back of this company had it brought into us how small and few we were under skies that on our right were packed with snow clouds. On the other side of the wall, but far down towards the pole, the skies were often still blue, and sometimes even warm, and down there were the greens and browns of a summery land, and the streams were quick and lively. To our right the grey and dour landscape was obscured again and again by snow. We could see that the whiteness of cold had claimed the far mountains on our right, and was covering the foothills and spreading out down the valleys. And the winds that come pouring down from there hurt our lungs and made our eyes sting, so that we turned our heads away and looked down over the part of our world that still said to us, Welcome, here nature is as warm and as comfortable as your flesh. But Canopus kept directing us â gently, but making sure we did it â to look as much as we could into the world of cold.
And so we went, day after day, and it was as if we walked into a spreading blight, for soon, even on the left side of the wall we saw how grasses shrank and dimmed and vegetation lost its lustre, and the skies lowered themselves with a white glare somewhere behind the blue. And on the right the snows were reaching down, down, towards us, and our familiar landscapes were hard to recognize.
There was a day that we stood all together on our barrier wall, looking up into the freezing immensities, with Canopus among us, and we saw that the enormous heavy animals that Canopus had brought us from another of their planets were crowding close in to the wall. They massed there, in vast herds, with the snow driving down behind them, and they were lifting their great heads and wild trapped eyes at the wall, which they could not cross. A short way ahead of us was a narrow gap which we had closed with a sliding door half the wallâs height.
Canopus did not have to tell us what we must do. Some of us went down the side of the wall on to the rough soil, where the grasses had long since gone, leaving a thin crust of lichens, and pulled back the gates. The herds lifted their heads and swung their horns and trampled their feet in indecision, and then saw that this was their deliverance â and first one beast and then another charged through the gap, and soon from all over the frozen lands came charging and thundering herds of animals, and they all, one after another, went through the gap. What heavy clumsy beasts they were! We could never become accustomed to their mass and weight and ponderousness. On their heads were horns which at their base were thicker than our thighs, and sometimes they had four and even six horns. Their hooves left behind prints that would make small ponds. Their shoulders, to support these crests and clubs of bone, were like the slopes of hills. Their eyes were red and wild and
