‘But that’s atomicV Knahr gasped the thought. ‘Fall-out!’
‘No fall-out. Complete conversion. Have you got a counter?’
They had. They tested. There was nothing except the usual background count.
There’s no life left underground, so you needn’t keep this squad of gunners tied up here,’ Garlock told the commander. ‘Before we go, I want to ask a question. You have visitors once in a while from other solar systems, so you must have a faster-than-light drive. Can you tell me anything about it?”
‘No. Nothing like that would be any of my business.’
Knahr and the four gunners disappeared; the helicopters began to lumber away.
‘Well, that helps – I don’t think,’ Garlock thought, glumly. ‘What a world! Back to the Main?’
In the Main, after a long and fruitless discussion, Garlock called Governor Atterlin, who did not know anything about any faster-than-light drive, either. There was one, of course, since it took only a few days or a few weeks to go from one system to another; but Hodell didn’t have any such ships. No ordinary planet did. They were owned and operated by people who called themselves ‘Engineers’. He had no idea where these Engineers came from; they didn’t say.
Garlock then tried to get in touch with the Arpalone inspector who had checked the Pleiades in, and could not find out even who it had been. The inspector then on duty neither knew
52
or cared anything about either faster-than-light drives or Engineers. Such things were none of his business.
‘What difference would it make, anyway?’ James asked. ‘No drive that takes “a few weeks” for an intra-galactic hop is ever going to get us back to Tellus.’
True enough; but if there is any such thing I want to know how it works. How are you coming?’
‘I’ll finish up tomorrow easily enough.’
Tomorrow came, and James finished up, but he did not find any familiar pattern of galactic arrangement. The other three watched James set up for another try for Earth.
‘You don’t think we’ll ever get back, do you, Clee?’ Belle asked.
‘Not right away, no. But someday, yes. I’ve got the germ of an idea. Maybe three or four more hops will give me something to work on.’
T hope so,’ James said, ‘because here goes nothing,’ and he snapped the red switch.
It was not nothing. Number Two was another Arpalone inspector and another planet very much like Hodell. It proved to be so far away from both Earth and Hodell, however, that no useful similarities were found in any two of the three sets of charts.
Number Three was equally unproductive of helpful results. James did, however, improve his technique of making galactic charts; and he and Garlock designed and built a high-speed comparator. Thus the time required per stop was reduced from days to hours.
Number Four produced a surprise. When Garlock touched the knob of the testing-box he yanked his hand away before it had really made contact. It was like touching a high-voltage wire.
‘You are incompatible with our humanity and must not land,’ the inspector ruled.
‘Suppose we blast you and your jets out of the air and land anyway?’ Garlock asked.
“That is perhaps possible,’ the Arpalone agreed, equably enough. ‘We are not invincible. However, it would do you no good. If any one of you four leaves that so-heavily-insulated
53
vessel in the atmosphere of this planet you will surely die. Not quickly, but slowly and with difficulty.’
‘But you haven’t tested me\’ Belle said. ‘Do you mean they’ll attack us on sight?’
There is no need to test more than one. Anyone who could live near any of you could not live on this planet. Nor will anyone attack you. Don’t you know what the thought “incompatible” means?’
‘With us it does not mean death.’
‘Here it does, since it refers to life forces. The types are mutually, irreconcilably antagonistic. Your life forces are very strong. Thus, no matter how peaceable your intentions may be, many of our human beings would die before you would; but you would not live to get back to your ship if you landed it and left its protective insulation.’
‘Why? What is it? How does it work?’ Belle demanded. ‘It is not my business to know; only to tell. I have told. You will go away now.’
Oarlock’s eyes narrowed in concentration. ‘Belle, can you blast? I mean, could you if you wanted to?’ ‘Certainly … but I don’t want to, Clee!’ ‘I don’t, either – and I’ll file that one away to chew on some night when I’m hungry, too. Take her up, Jim, and try another shot’
Numbers Five to Nine were neither productive nor eventful. All were, like the others, Hodell all over again, in everything fundamental. One was so far advanced that almost all of its humanity were Seconds; one so backward – or so much younger – that its strongest telepaths were only Fours. The Tellurians became acquainted with, and upon occasion fought with, various types of man-sized monsters in addition to the three varieties they had seen on Hodell.
Every planet they visited had Arpalones and Arpales. Not by those names, of course. Local names for planets, guardians, nations, cities, and persons went into the starship’s tapes. Every planet they visited was peopled by Homo Sapiens, capable of interbreeding with the Tellurians and eager to do so – especially with the Tellurian men. Their strict monogamy was really tested more than once; but it held. Each had been visited repeatedly by starships; but all Garlock could find out
54
about them was that they probably came from some world somewhere that was inhabited by compatible human beings of Grade Two. He could learn nothing about the faster-than-light drive.
Number Ten was another strange one – the Tellurians were found incompatible.
‘Let’s go down anyway,’ Belle suggested. ‘Overcome this unwillingness of ours and find out. What do you think they’ve got down there, Clee, that could possibly handle you and me both?’
‘I don’t think it’s a case of “handling” at all. I don’t know what it is, but I believe it’s fatal. We won’t go down.’
‘But it doesn’t make sense!’ Belle protested.
‘Not yet, no; but it’s a datum. Enough data and we’ll be able to formulate a theory.’
‘You and your theories! I wish we could get some facts!’
‘You can call that a fact. But I want you and Jim to do some math. We know that we’re making mighty long jumps. Assuming that they’re at perfect random and of approximately the same length, the probability is greater than one-half that we’re getting farther and farther away from Tellus. Is there a jump number, N, at which the probability is one-half that we land nearer Tellus instead of farther away? My jump-at-conclu-sions guess is that there isn’t – that the first jump set up a bias.’
‘Ouch. That isn’t in any of the books,’ James said. ‘In other words, do we or do we not attain a maximum? You’re making some poor assumptions – among others that space isn’t curved and that the dimensions of the universe are very large compared to the length of our jumps. I’ll see if I can put it into shape to feed to Compy. You’ve always held that these generators work at random – the rest of those assumptions are based on your theory?’
‘Check. I’m not getting anywhere studying my alleged Xeno-logy, so I’m going to work full time on designing a generator that will steer.’
‘You tried it before. So did everybody else.’
‘I know it, but I’ve got a lot more data now. And I’m not promising; just trying. Okay?’
‘Sure – I’m in favor of anything that has any chance at all of
55
working.’
Jumping went on; and Garlock, instead of going abroad on the planets, stayed aboard the Pleiades and worked.
At Number Forty Three, their reception was of a new kind. They were compatible with the people of this world, but the Inspector advised them against landing.
‘I do not forbid you,’ he explained carefully. ‘Our humans are about to destroy themselves with fission and fusion bombs. They send missiles, without warning, against visitors. Thus, the last starship to visit us here disregarded my warning and sent down a sensing device as usual – Engineers do not land on non-telepathic worlds, you know – and it was destroyed.’
‘You’re a Guardian of Humanity,’ Garlock said. ‘Can’t you straighten your people out?’
‘Of course not!’ The Arpalone was outraged. ‘We guard humanity against incompatible and non-humans; but it is not our business to interfere with humanity if it wishes to destroy itself. That is its privilege and its own business.’
Garlock probed downward. ‘No telepathy, not even – not even a Seven. This planet is backward – back to Year One. And nothing but firecrackers… We’re going down.’
‘Good!’ Belle said. ‘This will break the monotony, at least.’ And the others agreed.
