Now that the herds had all gone through the wall, we filled the gap by pushing across the gate. But Canopus said that as soon as we got back to our houses, work parties must be sent out, and this gap, and the others that had been left, must be built up as strongly and thickly as all the rest of the wall. For the openings that had been ordered to be left in the wall long before there had been cold, or even the first signs of cold, to save animals that had not even been brought to our planet, had fulfilled their purpose. We no longer needed them. The wall must be perfect and whole and without a weak place.
We walked on for some days after that before there was a blizzard of an intensity we had not even been able to imagine. We huddled on the safe side of the wall, while the winds screamed over us and sometimes came sucking and driving down where we were, and we shivered and we shrank, and knew that we had not begun to imagine what we had, all of us, to face. And when the screaming and scouring stopped and we climbed up the little projecting steps to the top, carefully because of the glaze of ice on them, we saw that on the cold side snow had fallen so heavily that all the hollows and the heights of the landscape were filled in with billowy white, and the wall was only half its previous height.
By then we were not far from our starting place, and we all longed to be back in our homes, our new thick-walled solid houses with roofs that had been pitched to throw off any snowfall - so we had thought. But now wondered. Were we going to have to live under snow as some creatures lived under water? Were we going to have to make little tunnels and caves for ourselves under a world of snow?
But still, on our side of the wall, where our towns and cities and farms spread, there was some green, there was the shine of moving water. And knowing of our hunger and our desperation and our longing, Canopus did not now make us turn our faces from this livingness, but allowed us to stumble on, looking warmthwards, trying to ignore the snowy wilderness that was crowding down on us.
And it was during these days that Johor fell back with me, and talked to me, alone. I listened to him and I had my eyes on my fellows in front, the Representatives, and when I knew that what I was being told was for me, and not for them - not yet, at least, because they could not yet face it - there came into me an even deeper sense of what was in store. But what worse could there possibly be?
Ahead of us this great wall of ours stood high and black above marshes where the snows of the blizzard had partly melted, leaving streaks and blobs of thin white on dark water. We stood there, Johor and I, and watched our companions walk away, and become no more than a moving blur on the crest of the wall where it rose to cross a ridge and then disappeared from our view. It climbed again, and we saw it, still mighty and tall though so far away, showing exactly what its nature was, for on one side the snows piled, and on the other the beasts fed on wintry grass and on low grey bushes.
Johor touched my arm, and we walked forward to stand where the marshes lay on either side. On the right the dark white-streaked waters seemed channels to the world of snow and ice. But on the other side the marshes were an estuary which led to the ocean. We called it that, though it was really a large lake, enclosed by land. We had been told of, and some of us had seen, planets that were more water than land - where lumps and pieces and even large areas of land were in watery immensities. It is hard to believe in something very far from experience. With us everything was the other way about. Our 'ocean' was always a marvel to us. Was precious. Our lives depended on it, we knew that, for it helped us to make our atmosphere. It seemed to us to represent distant and rare truths, was a symbol to us of what was hard to attain and must be guarded and sheltered. Those of you who live on planets where liquids are as common as earth and rocks and sand will find it as hard to imagine our cherishing of this 'ocean' of ours as we found it to visualize planets where water masses bathed the whole globe in a continuous living movement, speaking always of wholeness, oneness, interaction, of rapid and easy interchange. For the basis of our lives, the substance which bound us in continuity, was earth. Oh yes, we knew that this soil and rock that made our planet, with water held so shallowly in it, and only in one place, except for the streams and rivers that fed it, was something that moved, just as water moved - we knew rock had its currents, like water. We knew it because Canopus had taught us to think like this. Solidity, immobility, permanence - this was only how we with our Planet 8 eyes had to see things. Nowhere, said Canopus, was permanence, was immutability - not anywhere in the galaxy, or the universe. There was nothing that did not move and change. When we looked at a stone, we must think of it as a dance and a flow. And at a hillside. Or a mountain.
I was standing there with my back to the icy winds, face towards our precious lake that was out of sight beyond tall plumy reeds, and I was thinking: And ice? -we must see this new enemy of ours as something all fluidity and movement? And it was at that moment that it came into me for the first time that our ocean might freeze. Even though it was on the 'safe' side of our barrier wall. The thought came like a blast of cold. I knew it would be so, and I already felt something of what Canopus was going to tell me. I did not want to turn and face Johor - face what I had to.
I felt his touch on my elbow again and I did turn.
I saw him as he saw me, fragile and vulnerable inside thick pelts, hands hidden inside sleeves, eyes peering out from deep shaggy hoods.
It is a hard thing, to lose the sense of physical appropriateness - and again my eyes went skywards where an eagle lay poised on air just above us.
'Representative,' said Johor gently, and I made my gaze return downwards, to what I could see of his yellow face.
'Your ocean will freeze,' he said.
I could feel my bones huddle and tremble inside my thin flesh.
I tried to joke: 'Canopus can bring us new beasts with heavy bones for the cold - but what can you do for our bones? Or shall we all die out as our other animals did, to make way for new species - new races?'
'You will not die out,' he said, and his strong brown eyes - inflamed though, and strained - were forcing me to look at him.
Another new thought came into me, and I asked: 'You were not born on Canopus, so you said. What kind of planet did you come from?'
'I was given existence on a warm and easy planet.'
'As Planet 8 was, once.'
'As the planet is that you will all be going to.'
At this I was silent for a very long time. There were too many adjustments to make in my thoughts - which whirled about and did not settle into patterns that could frame useful questions.
When I was slightly recovered, I still was facing Johor, who stood with his back to a wind that came pouring down from the snow fields.
'You are always travelling,' I said. 'You are seldom on your own planet - do you miss it?'
He did not answer. He was waiting.
'If we are all to be space-lifted away from our home, then why the wall? Why were we not taken away when the snows first began to fall?'
