He stooped and scratched Nathaniel's ear and the dog, tail wagging to a stop, stood and watched him climb the hill.
IV. DESERTION
NOTES ON THE FOURTH TALE
Four men, two by two, had gone into the howling maelstrom that was Jupiter and had not returned. They had walked into the keening gale — or rather, they had loped, bellies low against the ground, wet sides gleaming in the rain.
For they did not go in the shape of men.
Now the fifth man stood before the desk of Kent Fowler, head of Dome No. 3, Jovian Survey Commission.
Under Fowler's desk, old Towser scratched a flea, then settled down to sleep again.
Harold Allen, Fowler saw with a sudden pang, was young — too young. He had the easy confidence of youth, the face of one who never had known fear. And that was strange. For men in the domes of Jupiter did know fear — fear and humility.
It was hard for Man to reconcile his puny Self with the mighty forces of the monstrous planet.
'You understand,' said Fowler, 'that you need not do this. You understand that you need not go.'
It was formula, of course. The other four had been told the same thing, but they had gone. This fifth one, Fowler knew, would go as well. But suddenly he felt a dull hope stir within him that Allen wouldn't go.
'When do I start?' asked Allen.
There had been a time when Fowler might have taken quiet pride in that answer, but not now. He frowned briefly.
'Within the hour,' he said.
Allen stood waiting, quietly.
'Four other men have gone out and have not returned,' said Fowler. 'You know that, of course. We want you to return. We don't want you going off on any heroic rescue expedition. The main thing, the only thing is that you come back, that you prove man can live in a Jovian form. Go to the first survey stake, no farther, then come back. Don't take any chances. Don't investigate anything. Just come back.'
Allen nodded. 'I understand all that.'
'Miss Stanley will operate the converter,' Fowler went on. 'You need have no fear on that particular score. The other men were converted without mishap. They left the converter in apparently perfect condition. You will be in thoroughly competent hands. Miss Stanley is the best qualified conversion operator in the Solar System. She has had experience on most of the other planets. That is why she's here.'
Allen grinned at the woman and Fowler saw something flicker across Miss Stanley's face — something that might have been pity, or rage — or just plain fear. But it was gone again and she was smiling back at the youth who stood before the desk. Smiling in that prim, school-teacherish way she had of smiling, almost as if she hated herself for doing it
'I shall be looking forward,' said Allen, 'to my conversion.'
And the way he said it, he made it all a joke, a vast ironic joke.
But it was no joke.
It was serious business, deadly serious. Upon these tests, Fowler knew, depended the fate of men on Jupiter. If the tests succeeded, the resources of the giant planet would be thrown open. Man would take over Jupiter as he already had taken over the other smaller planets. And if they failed — if they failed, Man would continue to be chained and hampered by the terrific pressure, the greater force of gravity, the weird chemistry of the planet. He would continue to be shut within the domes, unable to set actual foot upon the planet, unable to see it with direct, unaided vision, forced to rely upon the awkward tractors and the televisor, forced to work with clumsy tools and mechanisms or through the medium of robots that themselves were clumsy.
For Man, unprotected and in his natural form, would be blotted out by Jupiter's terrific pressure of fifteen thousand pounds per square inch, pressure that made terrestrial sea bottoms seem a vacuum by comparison.
Even the strongest metal Earthmen could devise couldn't exist under pressure such as that, under the pressure and the alkaline rains that forever swept the planet. It grew brittle and flaky, crumbling like clay, or it ran away in little streams and puddles of ammonia salts. Only by stepping up the toughness and strength of that metal, by increasing its electronic tension, could it be made to withstand the weight of thousands of miles of swirling, choking gases that made up the atmosphere. And even when that was done, everything had to be coated with tough quartz to keep away the rain — the liquid ammonia that fell as bitter rain.
Fowler sat listening to the engines in the sub-floor of the dome-engines that ran on endlessly, the dome never quiet of them. They had to run and keep on running, for if they stopped the power flowing into the metal walls of the dome would stop, the electronic tension would ease up and that would be the end of everything.
Towser roused himself under Fowler's desk and scratched another flea, his leg thumping hard against the floor.
'Is there anything else?' asked Allen.
Fowler shook his head. 'Perhaps there's something you want to do,' he said. 'Perhaps you-'
He had meant to say write a letter and he was glad he caught himself quick enough so he didn't say it.
Allen looked at his watch. 'I'll be there on time,' he said. He swung around and headed for the door.
Fowler knew Miss Stanley was watching him and he didn't want to turn and meet her eyes. He fumbled with a sheaf of papers on the desk before him.
