He soon fell back into the old routine of sleeping and basking, punctuated with the making of some scribbled notes for his Malacandrian dictionary. He knew that there was very little chance of his being able to communicate his new knowledge to man, that unrecorded death in the depth of space would almost certainly be the end of their adventure. But already it had become impossible to think of it as 'space.' Some moments of cold fear he had; but each time they were shorter and more quickly swallowed up in a sense of awe which made his personal fate seem wholly insignificant. He could not feel that they were an island of life journeying through an abyss of death. He felt almost the opposite - that life was waiting outside the little iron eggshell in which they rode, ready at any moment to break in, and that, if it killed them, it would kill them by excess of its vitality. He hoped passionately that if they were to perish they would perish by the 'unbodying 'of the space-ship and not by suffocation within it. To be let out, to be set free, to dissolve into the ocean of eternal noon, seemed to him at certain moments a consummation even more desirable than their return to Earth. And if he had felt some such lift of the heart when first he passed through heaven on their outward journey, he felt it now tenfold, for now he was convinced that the abyss was full of life in the most literal sense, full of living creatures.
His confidence in Oyarsa's words about the eldila increased rather than diminished as they went on. He saw none of them; the intensity of light in which the ship swam allowed none of the fugitive variations which would have betrayed their presence. But he heard, or thought he heard, all kinds of delicate sound, or vibrations akin to sound, mixed with the tinkling rain of meteorites, and often the sense of unseen presences even within the space-ship became irresistible. It was this, more than anything else, that made his own chances of life seem so unimportant. He and all his race showed small and ephemeral against a background of such immeasurable fullness. His brain reeled at the thought of the true population of the universe, the three-dimensional infinitude of their territory, and the unchronicled aeons of their past; but his heart became steadier than it had ever been.
It was well for him that he had reached this frame of mind before the real hardships of their journey began. Ever since their departure from Malacandra, the thermometer had steadily risen; now it was higher than it had stood at any time on their outward journey. And still it rose. The light also increased. Under his glasses he kept his eyes habitually tight shut, opening them only for the shortest time for necessary movements. He knew that if he reached Earth it would be with permanently damaged sight. But all this was nothing to the torment of heat. All three of them were awake for twenty-four hours out of the twenty-four, enduring with dilated eyeballs, blackened lips and froth-flecked cheeks the agony of thirst. It would be madness to increase their scanty rations of water: madness even to consume air in discussing the question.
He saw well enough what was happening. In his last bid for life Weston was venturing inside the Earth's orbit, leading them nearer the Sun than man, perhaps than life, had ever been. Presumably this was unavoidable; one could not follow a retreating Earth round the rim of its own wheeling course. They must be trying to meet it - to cut across ... it was madness! But the question did not much occupy his mind; it was not possible for long to think of anything but thirst. One thought of water; then one thought of thirst; then one thought of thinking of thirst; then of water again. And still the thermometer rose. The walls of the ship were too hot to touch. It was obvious that a crisis was approaching. In the next few hours it must kill them or get less.
It got less. There came a time when they lay exhausted and shivering in what seemed the cold, though it was still hotter than any terrestrial climate. Weston had so far succeeded; he had risked the highest temperature at which human life could theoretically survive, and they had lived through it. But they were not the same men. Hitherto Weston had slept very little even in his watches off; always, after an hour or so of uneasy rest, he had returned to his charts and to his endless, ahnost despairing, calculations. You could see him fighting the despair - pinning his terrified brain down, and again down, to the figures. Now he never looked at them. He even seemed careless in the control room. Devine moved and looked like a somnambulist. Ransom lived increasingly on the dark side and for long hours he thought of nothing. Although the first great danger was past, none of them, at this time, had any serious hope of a successful issue to their journey. They had now been fifty days, without speech, in their steel shell, and the air was already very bad.
Weston was so unlike his old self that he even allowed Ransom to take his share in the navigation. Mainly by signs, but with the help of a few whispered words, he taught him all that was necessary at this stage of the journey. Apparently they were racing home - but with little chance of reaching it in time - before some sort of cosmic 'trade-wind.' A few rules of thumb enabled Ransom to keep the star which Weston pointed out to him in its position at the centre of the skylight, but always with his left hand on the bell to Weston's cabin.
This star was not the Earth. The days - the purely theoretical 'days' which bore such a desperately practical meaning for the travellers - mounted to fifty-eight before Weston changed course, and a different luminary was in the centre. Sixty days, and it was visibly a planet.
Sixty-six, and it was like a planet seen through field-glasses. Seventy, and it was like nothing that Ransom had ever seen - a little dazzling disk too large for a planet and far too small for the Moon. Now that he was navigating, his celestial mood was shattered. Wild, animal thirst for life, mixed with homesick longing for the free airs and the sights and smells of earth - for grass and meat and beer and tea and the human voice - awoke in him. At first his chief difficulty on watch had been to resist drowsiness; now, though the air was worse, feverish excitement kept him vigilant. Often when he came off duty he found his right arm stiff and sore; for hours he had been pressing it unconsciously against the control board as if his puny thrust could spur the space-ship to yet greater speed.
Now they had twenty days to go. Nineteen - eighteen - and on the white terrestrial disk, now a little larger than a sixpence, he thought he could make out Australia and the south-east corner of Asia. Hour after hour, though the markings moved slowly across the disk with the Earth's diurnal revolution, the disk itself refused to grow larger. "Get on! Get on!" Ransom muttered to the ship. Now ten days were left and it was like the Moon and so bright that they could not look steadily at it. The air in their little sphere was ominously bad, but Ransom and Devine risked a whisper as they changed watches.
"We'll do, it," they said. "We'll do it yet."
On the eighty-seventh day, when Ransom relieved Devine, he thought there was something wrong with the Earth. Before his watch was done, he was sure. It was no longer a true circle, but bulging a little on one side; it was almost pear-shaped. When Weston came on duty he gave one glance at the skylight, rang furiously on the bell for Devine, thrust Ransom aside, and took the navigating seat. His face was the colour of putty. He seemed to be about to do something to the controls, but as Devine entered the room he looked up and shrugged his shoulders with a gesture of despair. Then he buried his face in his hands and laid his head down on the control-board.
Ransom and Devine exchanged glances. They bundled Weston out of the seat - he was crying like a child - and Devine took his place. And now at last Ransom understood the mystery of the bulging Earth. What had appeared as a bulge on one side of her disk was becoming increasingly distinct as a second disk, a disk almost as large in appearance as her own. It was covering more than half of the Earth. It was the Moon - between them and the Earth, and two hundred and forty thousand miles nearer. Ransom did not know what fate this might mean for the space-ship. Devine obviously did, and never had he appeared so admirable. His face was as pale as Weston's, but his eyes were clear and preternaturally bright; he sat crouched over the controls like an animal about to spring and he was whistling very softly between his teeth.
Hours later Ransom understood what was happening. The Moon's disk was now larger than the Earth's, and very gradually it became apparent to him that both disks were diminishing in size. The space-ship was no longer approaching either the Earth or the Moon; it was farther away from them than it had been half an hour ago, and that was the meaning of Devine's feverish activity with the controls. It was not merely that the Moon was crossing their path and cutting them off from the Earth; apparently for some reason - probably gravitational - it was dangerous to get too close to the Moon, and Devine was standing off into space. In sight of harbour they were being forced to turn back to the open sea. He glanced up at the chronometer. It was the morning of the eighty-eighth day. Two days to make the Earth, and they were moving away from her.
