Stryker prodded him socratically: "Particulars?"

"When we crashed here five weeks ago, there were an even thousand

natives in the village, plus or minus a few babes in arms. Since

that time they've lost a hundred twenty-six members, all suicides or

murders. At first the entire population turned out at sunrise and went

into the dome for an hour before going to the fields; since we came,

that period has shortened progressively to a few minutes. That much

we've learned by observation. By direct traffic we've learned exactly

nothing except that they can speak Terran Standard, but won't. What

sort of system is that?"

Stryker tugged uncomfortably at the rim of white hair the years had

left him. "It's a stumper for the moment, I'll admit ... if they'd

only _talk_ to us, if they'd tell us what their wants and fears and

problems are, we'd know what is wrong and what to do about it. But

controls forced on them by the Hymenops, or acquired since their

liberation, seem to have altered their original ideology so radically

that--"

"That they're plain batty," Farrell finished for him. "The whole setup

is unnatural, Lee. Consider this: We sent Xavier out to meet the first

native that showed up, and the native talked to him. We heard it all by

monitoring; his name was Tarvil, he spoke Terran Standard, and he was

amicable. Then we showed ourselves, and when he saw that we were human

beings like himself and not mechanicals like Xav, he clammed up. So did

everyone in the village. It worries me, Lee. If they didn't expect men

to come out of the _Marco_, then what in God's name _did_ they expect?"

He sat up restlessly and stubbed out his cigarette. "It's an

unimportant world anyway, all ocean except for this one small

continent. I think we ought to write it off and get the hell out as

soon as the _Marco_'s Ringwave is repaired."

"We can't write it off," Stryker said. "Besides reclaiming a colony, we

may have added a valuable marine food source to the Federation. Arthur,

you're not letting a handful of disoriented people get under your

skin, are you?"

Farrell made an impatient sound and lit another cigarette. The brief

flare of his lighter pierced the darkness and picked out a hurried

movement a short stone's throw away, between the _Marco Four_ and the

village.

* * * * *

"There's one reason why I'm edgy," Farrell said. "These Sadrians may

be harmless, but they make a point of posting a guard over us. There's

a sentry out there in the grass flats again tonight." He turned on

Stryker uneasily. "I've watched on the infra-scanner while those

sentries changed shifts, and they don't speak to each other. I've

tracked them back to the village, but I've never seen one of them turn

in a--"

Down in the village a man screamed, a raw, tortured sound that brought

both men up stiffly. A frantic drumming of running feet came to them,

unmistakable across the little distance. The fleeing man came up from

the dark huddle of cottages by the river and out across the grass

flats, screaming.

Pursuit overtook him halfway to the ship. There was a brief scuffling,

a shadowy dispersal of silent figures. After that, nothing.

"They did it again," Farrell said. "One of them tried to come up here

to us. The others killed him, and who's to say what sort of twisted

motive prompted them? They go to the dome together every morning, not

speaking. They work all day in the fields without so much as looking at

each other. But every night at least one of them tries to escape from

the village and come up here--and this is what happens. We couldn't

trust them, Lee, even if we could understand them!"

"It's our job to understand them," Stryker said doggedly. "Our function

is to find colonies disoriented by the Hymenops and to set them

straight if we can. If we can't, we call in a long-term reorientation

crew, and within three generations the culture will pass again for

Terran. The fact that slave colonies invariably lose their knowledge of

longevity helps; they don't get it back until they're ready for it.

"I've seen some pretty foul results of Hymenop experimenting

on human colonies, Arthur. There was the ninth planet of Beta

Pegasi--rediscovered in 3910, I think it was--that developed a

religious fixation on fertility, a mania fostered by the Hymenops to

supply expendable labor for their mines. The natives stopped mining

when the Hymenops gave up the invasion and went back to 70 Ophiuchi,

but they were still multiplying like rabbits when we found them. They

followed a cultural conviction something like that observed in Oriental

races of ancient Terran history, but they didn't pursue the Oriental

tradition of sacrosancts. They couldn't--there were too many of them.

By the time they were found, they numbered fourteen _billions_ and they

were eating each other. Still it took only three generations to set

them straight."

He took one of Farrell's cigarettes and puffed it placidly.

"For that matter, Earth had her own share of eccentric cultures. I

recall reading about one that existed as late as the twentieth century

and equaled anything we're likely to find here. Any society should be

geared to a set of social controls designed to furnish it, as a whole

with a maximum of pleasure and a minimum of discomfort, but these

ancient Terrestrial Dobuans--island aborigines, as I remember it--had

adjusted to their total environment in a manner exactly opposite. They

reversed the norm and became a society of paranoiacs, hating each

other in direct ratio to nearness of relationship. Husbands and wives

detested each other, sons and fathers--"

"Now you're pulling my leg," Farrell protested. "A society like that

would be too irrational to function."

"But the system worked," Stryker insisted. "It balanced well enough, as

long as they were isolated. They accepted it because it was all they

knew, and an abrupt reversal that negated their accustomed habits would

create an impossible societal conflict. They were reoriented after

the Fourth War, and succeeding generations adjusted to normal living

without difficulty."

A sound from overhead made them look up. Gibson was standing in the

_Marco's_ open port.

"Conference," Gibson said in his heavy baritone, and went back inside.

* * * * *

They followed Gibson quickly and without question, more disturbed by

the terse order than by the killing in the grass flats. Knowing Gibson,

they realized that he would not have wasted even that one word unless

emergency justified it.

They found him waiting in the chart room with Xavier. For the

thousandth time, seeing the two together, Farrell found himself

comparing them: the robot, smoothly functional from flexible gray

plastoid body to featureless oval faceplate, blandly efficient, totally

incapable of emotion; Gibson, short and dark and competent heavy-browed

and humorless. Except for initiative, Farrell thought, the two of them

could have traded identities and no one would have been able to notice

any difference.

"Xav and I found our Ringwave trouble," Gibson said. "The generator is

functioning, but the warp isn't going out. Something here on Sadr III

is neutralizing it."

They stared at him as if he had just told them the planet was flat.

"But a Ringwave can't be stopped completely, once it is started,"

Stryker protested. "You'd have to dismantle it to shut it off, Gib!"

"The warping field can be damped out, though," Gibson said. "Adjacent

generators operating at different phase levels will heterodyne at a

frequency representing the mean variance between levels. The resulting

beat-phase will be too low to maintain either field, and one or the

other, or both, will blank out. If you remember, all Terran-designed

power plants are set to the same phase for that reason."

"But these natives _can't_ have a Ringwave plant!" Farrell argued.

"There's only this one village on Sadr III, Gib, an insignificant

little agrarian township! If they had the Ringwave, they'd be

mechanized. They'd have vehicles, landing ports...."

"The Hymenops had the Ringwave," Gibson interrupted. "And they left the

dome down there, the first undamaged one we've found. Figure it out for

yourselves."

They digested the statement in silence. Stryker paled slowly, as if

it needed time for apprehension to work its way through his fat bulk.

Farrell's uneasiness, sourceless until now, grew to chill certainty.

* * * * *

"I think I've expected this, without realizing it, since my first

flight," he said. "It stood to reason that the Hymenops would quit

running somewhere, that we'd bump into them eventually out here on the

fringes. Twenty thousand light-years back to 70 Ophiuchi is a long way

to retreat.... Gib, do you think they're still here?"

Gibson did not shrug, but his voice seemed to. "It won't matter one way

or the other unless we can clear the _Marco's_ generator."

From another man it might have been irony. Knowing Gibson, Farrell and

Stryker accepted it as a bald statement of fact.

"Then we're up against a Hymenop hive-mind," Stryker said. "And we

can't run away from it. Any suggestions?"

"We'll have to find the interfering generator and stop it," Farrell

offered, knowing that was the only obvious solution.

"One alternative," Gibson corrected. "If we can determine what

phase-level the interfering warp uses, we may be able to adjust the

_Marco's_ generator to match it. Once they're in resonance, they won't

interfere." He caught Stryker's unspoken question and answered it. "It

would take a week. Maybe longer."

Stryker vetoed the alternative. "Too long. If there are Hymenops here,

they won't give us that much time."

Farrell switched on the chart room scanning screen and centered it

on the village downslope. Scattered cottages with dark tiled roofs

and lamp-bright windows showed up clearly. Out of their undisciplined

grouping swept the great hemispherical curve of the dome, glinting

dully metallic in the starshine.

"Maybe we're jumping to conclusions," he said. "We've been here for

five weeks without seeing a trace of Hymenops, and from what I've read

of them, they'd have jumped us the minute we landed. Chances are that

they left Sadr III in too great a hurry to wreck the dome, and their

Ringwave power plant is still running."

"You may be right," Stryker said, brightening. "They carried the fight

to us from the first skirmish, two hundred years ago, and they damned

near beat us before we learned how to fight them."

He looked at Xavier's silent plastoid figure with something like

affection. "We'd have lost that war without Xave's kind. We

couldn't match wits with Hymenop hive-minds, any more than a swarm

of grasshoppers could stand up to a colony of wasps. But we made

mechanicals that could. Cybernetic brains and servo-crews, ships that

thought for themselves...."

He squinted at the visiscreen with its cryptic, star-streaked dome.

"But they don't think as we do. They may have left a rear guard here,

or they may have boobytrapped the dome."

"One of us will have to find out which it is," Farrell said. He took

a restless turn about the chart room, weighing the probabilities. "It

seems to fall in my department."
