If not for himself, for whom? He waited for the answer to come welling up, for the memory to reassert itself, and in time he realized that he had gone groping back as far as he could go.
Slowly he withdrew from the rock, once more was upon the hillside above the red land beneath the yellow sky.
A portion of the nearby surface moved and as it moved, he saw that it was not a portion of the surface, but a creature that had a coloration which made it seem to be a part of the planet’s surface. It moved quickly, as if a shadow had brushed along and blurred the surface. It moved in short and flowing motions, and when it stopped its motion it became a part of the surface, blending into it.
It was watching him, he knew, looking him over, although what there was to see of him he could not imagine. Sensitive, perhaps, to another personality, to another thing that shared with it that strange and undefinable quality which made up life. A force field, he wondered – was that what he was, a disembodied intelligence carried in a force field?
He stayed still so the thing could look him over. It moved in its short, flowing dashes, all around him. It left a furrowed track behind it, it kicked up little spurts of sand as it made its dashes. It moved in closer.
And he had it. He held it motionless, wrapped up as if he held it in many hands. He examined it, not closely, not analytically, but only enough so he could tell what kind of thing it was. Protoplasmic and heavily shielded against the radiations, even designed, perhaps – although he could not be sure – to take advantage of the energy contained in the radiation. An organism, more than likely, that could not exist without the radiations, that needed them as other creatures might need warmth, or food, or oxygen. Intelligent and laced with a multitude of emotions – not, perhaps, the kind of intelligence that could build a complex culture, but a high level of animal intelligence. Perhaps still evolving in its intelligence. Give it a few more million years and it might contrive a culture.
He turned it loose. It flowed away, moving rapidly, straight away from him. He lost sight of it, but still could follow its movement for a time by its unreeling track and the spurts of sand it kicked into the air.
There was much work to do. an atmospheric profile, an analysis of the soil and of the micro-organisms that it might contain, a determination of the liquid in the brook, an examination of the plant life, a geological survey, measurement of the magnetic field, the intensity of the radiation. But first there should be a general survey of the planet to determine what sort of place it was, a pin-pointing of those areas that might be of economic interest.
And there it was again, another word he had not had before. Economic.
He searched inside himself, inside the theoretical intelligence enclosed within the hypothetical force field, for the purpose that was hinted in that single word. When he found it, it stood out sharp and clear – the one thing he had found that was sharp and clear. What was here that could be used and what would be the cost of obtaining it? A treasure hunt, he thought. That was the purpose of him. It was clear immediately that he, himself, had no use for treasure of any kind at all. There must be someone else who would have a use for it. Although when he thought of treasure a pleasurable thrill went through him.
What might there be in it for him, he wondered, this location of a treasure? What had been the profit to him in the finding of all those other treasures on all those other planets – although, come to think of it, there had not been treasure on every one of them. And on some of the others where there’d been, it had been meaningless, for planetary conditions had been such that it could not be got at. Many of the planets, he recalled, far too many of them, were such that only a thing such as himself would dare even to approach them.
There had been attempts, he remembered now, to recall him from some of the planets when it had become apparent they had no economic worth and that to further explore them would be a waste of time. He had resisted those attempts; he had ignored the summons to return to wherever it was he went when he did return. Because, in his simplistic ethic, when there was a job to do he did it and he did not quit until the job was done. Having started something, he was incapable of leaving off until it had been finished. It was a part of him, this single-minded stubbornness; it was a characteristic that was necessary to do the work he did.
If they had it one way, they could not have it two. He either was, or wasn’t. He did the job, or didn’t. He was so made that he had an interest in each problem that was presented him and would not leave off until he’d wrung the problem dry. They had to go along with that and they knew it now; they no longer bothered trying to recall him from a non-productive planet.
They? he asked himself, and remembered faintly other creatures such as he had been. They had indoctrinated him, they had made him what he was and they used him as they used the priceless planets he had found, but he did not mind the using, for it was a life and the only life he had. It either had been this life, or no life at all. He tried to recall circumstances, but something moved to block the recall. Exactly as he never could recall in all entirety, but only in fragments, the other planets he had visited. That, he thought at the time, might be a great mistake, for experience he had gathered on the other planets might have been valuable as guide lines on the one to which he currently had been sent. But for some reason, they did not allow it, but did their imperfect best to wipe from his memory all past experiences before he was sent out again. To keep him clear, they said; to guard him from confusion; to send a bright new mind, freed of all encumbrances, out to each new planet. That was why, he knew, he always arrived upon each planet groping for a meaning and purpose, with the feeling of being newly born to this particular planet and to nowhere else.
He did not mind. It still was a life and he saw a lot of places – very different places – and saw them, no matter what conditions might obtain, in perfect safety. For there was nothing that could touch him – tooth, or claw, or poison, no matter what the atmosphere, no matter what the radiation, there was nothing that could touch him. There was nothing of him to be touched. He walked – no, not walked, but moved – in utter nonchalance through all the hells the galaxy could muster.
A second sun was rising, a great swollen, brick-red star pushing its way above the horizon, with the first one just beginning to slide towards the west – as a matter of convenience, he thought of the big red one as rising in the east.
K2, he read it, thirty times, or so, the diameter of the Sun with a surface temperature that was possibly no more than 4,000 degrees. A binary system and maybe more than that; there might be other suns that he still had yet to see. He tried to calculate the distance, but that would not be possible with any accuracy until the giant had moved higher in the sky, until it had moved above the horizon that now bisected it.
But the second sun could wait, all the rest of it could wait. There was one thing he must see. He had not realized it before, but now he knew there was one thing about the landscape that had been nagging him. The crater did not fit. It had all the appearances of a crater, but it had no right to be there. It could not be volcanic, for it sat in the middle of a sandy terrain and the limestone thrusting from the hillside was sedimentary rock. There was no trace of igneous rock, no ancient lava flows. And the same objections still would hold if the crater had been formed by meteoric impact, for any meteorite that threw up a crater of that size would have turned tons of material into a molten mass and would have thrown out a sheet of magma, of which there was no sign.
He began drifting slowly in the direction of the crater. Beneath him the terrain remained unchanged – the red soil, the purple fruit and little else.
