There was a jagged spur of stone looming precipitously over a
river-valley. A thousand feet below, a broad stream ran westward to the
sea. Twenty miles to the east, a wall of mountains rose sheer against
the sky. Its peaks seemed to blend to a remarkable evenness of height.
There was rolling, tumbled ground between for as far as the eye could
see.
A speck in the sky came swiftly downward. Great pinions spread, and
flapped, and icy eyes surveyed the rocky space. With more great
flappings, Semper the eagle came to ground. He folded his huge wings
and turned his head jerkily, his eyes unblinking. A tiny harness held a
miniature camera against his chest. He strutted over the bare stone to
the highest point. He stood there, a lonely and arrogant figure in the
vastness.
There came crashings and rustlings, and then snuffling sounds. Sitka
Pete came lumbering out into the clear space. He wore a harness too,
and a pack. The harness was complex, because it had not only to hold a
pack in normal travel, but, when he stood on his hind legs, it must not
hamper the use of his forepaws in combat.
He went cagily all over the open area. He peered over the edge of the
spur's farthest tip. He prowled to the other side and looked down. He
scouted carefully. Once he moved close to Semper and the eagle opened
his great curved beak and uttered an indignant noise. Sitka paid no
attention.
He relaxed, satisfied. He sat down untidily, his hind legs sprawling.
He wore an air approaching benevolence as he surveyed the landscape
about and below him.
More snufflings and crashings. Sourdough Charley came into view with
Huyghens and Roane behind him. Sourdough carried a pack, too. Then
there was a squealing and Nugget scurried up from the rear, impelled
by a whack from his mother. Faro Nell appeared, with the carcass of a
staglike animal lashed to her harness.
"I picked this place from a space photo," said Huyghens, "to make a
directional fix from. I'll get set up."
He swung his pack from his shoulders to the ground. He extracted an
obviously self-constructed device which he set on the ground. It had
a whip aerial, which he extended. Then he plugged in a considerable
length of flexible wire and unfolded a tiny, improvised directional
aerial with an even tinier booster at its base. Roane slipped his pack
from his shoulders and watched. Huyghens slipped headphones over his
ears. He looked up and said sharply:
"Watch the bears, Roane. The wind's blowing up the way we came.
Anything that trails us--sphexes, for example--will send its scent on
before. The bears will tell us."
He busied himself with the instruments he'd brought. He heard the
hissing, frying, background noise which could be anything at all except
a human signal. He reached out and swung the small aerial around.
Rasping, buzzing tones came in, faintly and then loudly. This receiver,
though, had been made for this particular wave band. It was much more
efficient than the modified space phone had been. It picked up three
short buzzes, three long ones, and three short ones again. Three dots,
three dashes, and three dots. Over and over again. SOS. SOS. SOS.
Huyghens took a reading and moved the directional aerial a carefully
measured distance. He took another reading. He shifted it yet again and
again, carefully marking and measuring each spot and taking notes of
the instrument readings. When he finished, he had checked the direction
of the signal not only by loudness but by phase--he had as accurate a
fix as could possibly be had with portable apparatus.
* * * * *
Sourdough growled softly. Sitka Pete whiffed the air and arose from
his sitting position. Faro Nell whacked Nugget, sending him whimpering
to the farthest corner of the flea place. She stood bristling, facing
down-hill the way they'd come.
"Damn!" said Huyghens.
He got up and waved his arm at Semper, who had turned his head at the
stirrings. Semper squawked in a most un-eaglelike fashion and dived
off the spur and was immediately fighting the down-draught beyond it.
As Huyghens reached his weapon, the eagle came back overhead. He went
magnificently past, a hundred feet high, careening and flapping in the
tricky currents. He screamed, abruptly, and circled and screamed again.
Huyghens swung a tiny vision-plate from its strap to where he could
look into it. He saw, of course, what the little camera on Semper's
chest could see--reeling, swaying terrain as Semper saw it, though
without his breadth of field. There were moving objects to be seen
through the shifting trees. Their coloring was unmistakable.
"Sphexes," said Huyghens dourly. "Eight of them. Don't look for them to
follow our track, Roane. They run parallel to a trail on either side.
That way they attack in breadth and all at once when they catch up. And
listen! The bears can handle anything they tangle with! It's our job to
pick off the loose ones! And aim for the body! The bullets explode."
He threw off the safety of his weapon. Faro Nell, uttering thunderous
growls, went padding to a place between Sitka Pete and Sourdough.
Sitka glanced at her and made a whuffing noise, as if derisive of her
blood-curdling sounds. Sourdough grunted in a somehow solid fashion.
He and Sitka moved farther away from Nell to either side. They would
cover a wider front.
There was no other sign of life than the shrillings of the incredibly
tiny creatures which on this planet were birds, and Faro Nell's
deep-bass, raging growls, and then the click of Roane's safety going
off as he got ready to use the weapon Huyghens had given him.
Semper screamed again, flapping low above the treetops, following
parti-colored, monstrous shapes beneath.
Eight blue-and-tan fiends came racing out of the underbrush. They had
spiny fringes, and horns, and glaring eyes, and they looked as if they
had come straight out of hell. On the instant of their appearance
they leaped, emitting squalling, spitting squeals that were like the
cries of fighting tomcats ten thousand times magnified. Huyghens'
rifle cracked, and its sound was wiped out in the louder detonation
of its bullet in sphexian flesh. A tan-and-blue monster tumbled over,
shrieking. Faro Nell charged, the very impersonation of white-hot fury.
Roane fired, and his bullet exploded against a tree. Sitka Pete brought
his massive forepaws in a clapping, monstrous ear-boxing motion. A
sphex died.
Then Roane fired again. Sourdough Charley whuffed. He fell forward
upon a spitting bi-colored fiend, rolled him over, and raked with his
hind claws. The belly-hide of the sphex was tenderer than the rest.
The creature rolled away, snapping at its own wounds. Another sphex
found itself shaken loose from the tumult about Sitka Pete. It whirled
to leap on him from behind--and Huyghens fired very coldly--and two
plunged upon Faro Nell and Roane blasted one and Faro Nell disposed
of the other in truly awesome fury. Then Sitka Pete heaved himself
erect--seeming to drip sphexes--and Sourdough waddled over and pulled
one off and killed it and went back for another. And both rifles
cracked together and there was suddenly nothing left to fight.
* * * * *
The bears prowled from one to another of the corpses. Sitka Pete
rumbled and lifted up a limp head. Crash! Then another. He went
over the lot, whether or not they showed signs of life. When he had
finished, they were wholly still.
Semper came flapping down out of the sky. He had screamed and fluttered
overhead as the fight went on. Now he landed with a rush. Huyghens
went soothingly from one bear to another, calming them with his voice.
It took longest to calm Faro Nell, licking Nugget with impassioned
solicitude and growling horribly as she licked.
"Come along, now," said Huyghens, when Sitka showed signs of intending
to sit down again. "Heave these carcasses over a cliff. Come along!
Sitka! Sourdough! Hup!"
He guided them as the two big males somewhat fastidiously lifted up
the nightmarish creatures they and the guns together had killed, and
carried them to the edge of the spur of stone. They let the dead
beasts go bouncing and sliding down into the valley.
"That," said Huyghens, "is so their little pals will gather round them
and caterwaul their woe where there's no trail of ours to give them
ideas. If we'd been near a river, I'd have dumped them in to float
down-river and gather mourners wherever they stranded. Around the
station I incinerate them. If I had to leave them, I'd make tracks
away. About fifty miles upwind would be a good idea."
He opened the pack Sourdough carried and extracted giant sized swabs
and some gallons of antiseptic. He tended the three Kodiaks in turn,
swabbing not only the cuts and scratches they'd received, but deeply
soaking their fur where there could be suspicion of spilled sphex blood.
"This antiseptic deodorizes, too," he told Roane. "Or we'd be trailed
by any sphex who passed to leeward of us. When we start off, I'll swab
the bears' paws for the same reason."
Roane was very quiet. He'd missed his first shot with a bullet-firing
weapon--a beam hasn't the stopping-power of an explosive bullet--but
he'd seemed to grow savagely angry with himself. The last few seconds
of the fight, he'd fired very deliberately and every bullet hit. Now he
said bitterly:
"If you're instructing me so I can carry on should you be killed, I
doubt that it's worth while!"
Huyghens felt in his pack and unfolded the enlargements he'd made of
the space photos of this part of the planet. He carefully oriented
the map with distant landmarks. He drew a painstakingly accurate line
across the photo.
"The SOS signal comes from somewhere close to the robot colony," he
reported. "I think a little to the south of it. Probably from a mine
they'd opened up, on the far side--of course--of the Sere Plateau.
See how I've marked this map? Two fixes, one from the station and one
from here. I came away off-course to get a fix here so we'd have two
position-lines to the transmitter. The signal could have come from the
other side of the planet. But it doesn't."
"The odds would be astronomical against other castaways," protested
Roane.
"No-o-o-o," said Huyghens. "Ships have been coming here. To the
robot colony. One could have crashed. And I have friends, too."
He repacked his apparatus and gestured to the bears. He led them beyond
the scene of combat and very carefully swabbed off their paws, so they
could not possibly leave a trail of sphex-blood scent behind them. He
waved Semper, the eagle, aloft.
"Let's go," he told the Kodiaks. "Yonder! Hup!"
* * * * *
The party headed down-hill and into the jungle again. Now it was
Sourdough's turn to take the lead, and Sitka Pete prowled more
widely behind him. Faro Nell trailed the men, with Nugget. She kept
an extremely sharp eye upon the cub. He was a baby, still. He only
weighed six hundred pounds. And of course she watched against danger
from the rear.
Overhead, Semper fluttered and flew in giant circles and spirals, never
going very far away. Huyghens referred constantly to the screen which
showed what the air-borne camera saw. The image tilted and circled
and banked and swayed. It was by no means the best air-reconnaissance
that could be imagined. But it was the best that would work. Presently
Huyghens said:
"We swing to the right, here. The going's bad straight ahead, and it
looks like a pack of sphexes has killed and is feeding."
Roane was upset. He was dissatisfied with himself. So he said:
"It's against reason for carnivores to be as thick as you say! There
has to be a certain amount of other animal life for every meat-eating
beast! Too many of them would eat all the game and starve!"
"They're gone all winter," explained Huyghens, "which around here
isn't as severe as you might think. And a good many animals seem to
breed just after the sphexes go south. Also, the sphexes aren't around
all the warm weather. There's a sort of peak, and then for a matter
of weeks you won't see a one of them, and suddenly the jungle swarms
with them again. Then, presently, they head south. Apparently they're
migratory in some fashion, but nobody knows." He said dryly: "There
haven't been many naturalists around on this planet. The animal life
is inimical."
Roane fretted. He was a senior officer in the Colonial Survey, and
he was accustomed to arrival at a partly or completely-finished
colonial set-up, and to pass upon the completion or noncompletion of
the planned installation as designed. Now he was in an intolerably
hostile environment, depending upon an illegal colonist for his life,
engaged upon a demoralizingly indefinite enterprise--because the
mechanical spark-signal could be working long after its constructors
were dead--and his ideas about a number of matters were shaken. He was
alive, for example, because of three giant Kodiak bears and a bald
eagle. He and Roane could have been surrounded by ten thousand robots,
and they'd have been killed. Sphexes and robots would have ignored each
other, and sphexes would have made straight for the men, who'd have had
less than four seconds in which to discover for themselves that they
were attacked, prepare to defend themselves, and kill eight sphexes.
Roane's convictions as a civilized man were shaken. Robots were
marvelous contrivances for doing the expected: accomplishing the
planned; coping with the predicted. But they also had defects. Robots
could only follow instructions--if this thing happens, do this, if
that thing happens do that. But before something else, neither this
or that, robots were helpless. So a robot civilization worked only in
an environment where nothing unanticipated ever turned up, and human
supervisors never demanded anything unexpected. Roane was appalled.
He'd never encountered the truly unpredictable before in all his life
and career.
He found Nugget, the cub, ambling uneasily in his wake. The cub
flattened his ears miserably when Roane glanced at him. It occurred
to the man that Nugget was receiving a lot of disciplinary thumpings
from Faro Nell. He was knocked about physically, pretty much as Roane
was being knocked about psychologically. His lack of information and
unfitness for independent survival in this environment was being
hammered into him.
"Hi, Nugget," said Roane ruefully. "I feel just about the way you do!"
Nugget brighted visibly. He frisked. He tended to gambol. He looked
very hopefully up into Roane's face--and he stood four feet high at the
shoulder and would overtop Roane if he stood erect.
Roane reached out and patted Nugget's head. It was the first time in
all his life that he'd ever petted an animal.
He heard a snuffling sound behind him. Skin crawled at the back of his
neck. He whirled.
Faro Nell regarded him--eighteen hundred pounds of she-bear only ten
feet away and looking into his eyes. For one panicky instant Roane
went cold all over. Then he realized that Faro Nell's eyes were not
burning. She was not snarling. She did not emit those blood-curdling
sounds which the bare prospect of danger to Nugget had produced up
on the rocky spur. She looked at him blandly. In fact, after a moment
she swung off on some independent investigation of a matter that had
aroused her curiosity.
* * * * *
The traveling party went on, Nugget frisking beside Roane and tending
to bump into him out of pure cub-clumsiness. Now and again he looked
adoringly at Roane, in the instant and overwhelming affection of the
very young.
Roane trudged on. Presently he glanced behind again. Faro Nell was
now ranging more widely. She was well satisfied to have Nugget in the
immediate care of a man. From time to time he got on her nerves.
A little while later, Roane called ahead.
"Huyghens! Look here! I've been appointed nursemaid to Nugget!"
Huyghens looked back.
"Oh, slap him a few times and he'll go back to his mother."
"The devil I will!" said Roane querulously. "I like it!"
The traveling party went on.
When night fell, they camped. There could be no fire, of course,
because all the minute night-things about would come eagerly to
dance in the glow. But there could not be darkness, equally, because
night-walkers hunted in the dark. So Huyghens set out the barrier
lamps which made a wall of twilight about their halting place, and the
staglike creature Faro Nell had carried became their evening meal. Then
they slept--at least the men did--and the bears dozed and snorted and
waked and dozed again. But Semper sat immobile with his head under his
wing on a tree limb. And presently there was a glorious cool hush and
all the world glowed in morning light diffused through the jungle by a
newly risen sun. And they arose, and traveled again.
This day they stopped stock-still for two hours while sphexes puzzled
over the trail the bears had left. Huyghens discoursed calmly on the
need for an anti-scent, to be used on the boots of men and the paws of
bears, which would make the following of their trails unpopular with
sphexes. And Roane seized upon the idea and absorbedly suggested that
a sphex-repellent odor might be worked out, which would make a human
revolting to a sphex. If that were done--why--humans could go freely
about unmolested.
"Like stink-bugs," said Huyghens, sardonically. "A very intelligent
idea! Very rational! You can feel proud!"
And suddenly Roane, very obscurely, was not proud of the idea at all.
They camped again. On the third night they were at the base of that
remarkable formation, the Sere Plateau, which from a distance looked
like a mountain-range but was actually a desert tableland. And it was
not reasonable for a desert to be raised high, while lowlands had rain,
but on the fourth morning they found out why. They saw, far, far away,
a truly monstrous mountain-mass at the end of the long-way expanse
of the plateau. It was like the prow of a ship. It lay, so Huyghens
observed, directly in line with the prevailing winds, and divided them
as a ship's prow divides the waters. The moisture-bearing air-currents
flowed beside the plateau, not over it, and its interior was pure sere
desert in the unscreened sunshine of high altitudes.
* * * * *
It took them a full day to get halfway up the slope. And here, twice
as they climbed, Semper flew screaming over aggregations of sphexes
to one side of them or the other. These were much larger groups than
Huyghens had ever seen before--fifty to a hundred monstrosities
together, where a dozen was a large hunting-pack elsewhere. He looked
in the screen which showed him what Semper saw, four to five miles
away. The sphexes padded uphill toward the Sere Plateau in a long line.
Fifty--sixty--seventy tan-and-azure beasts out of hell.
"I'd hate to have that bunch jump us," he said candidly to Roane. "I
don't think we'd stand a chance."
"Here's where a robot tank would be useful," Roane observed.
"Anything armored," conceded Huyghens. "One man in an armored station
like mine would be safe. But if he killed a sphex he'd be besieged.
He'd have to stay holed up, breathing the smell of dead sphex, until
the odor had gone away. And he mustn't kill any others or he'd be
besieged until winter came."
Roane did not suggest the advantages of robots in other directions.
At that moment, for example, they were working their way up a slope
which averaged fifty degrees. The bears climbed without effort despite
their burdens. For the men it was infinite toil. Semper, the eagle,
manifested impatience with bears and men alike, who crawled so slowly
up an incline over which he soared.
He went ahead up the mountainside and teetered in the air-currents at
the plateau's edge. Huyghens looked in the vision-plate by which he
reported.
"How the devil," panted Roane--they had stopped for a breather, and the
bears waited patiently for them--"do you train bears like these? I can
understand Semper."
"I don't train them," said Huyghens, staring into the plate. "They're
mutations. In heredity the sex-linkage of physical characteristics
is standard stuff. But there's been some sound work done on the
gene-linkage of psychological factors. There was need, on my home
planet, for an animal who could fight like a fiend, live off the land,
carry a pack and get along with men at least as well as dogs do. In the
old days they'd have tried to breed the desired physical properties
into an animal who already had the personality they wanted. Something
like a giant dog, say. But back home they went at it the other way
about. They picked the wanted physical characteristics and bred for the
personality--the psychology. The job got done over a century ago--a
Kodiak bear named Kodius Champion was the first real success. He had
everything that was wanted. These bears are his descendants."
"They look normal," commented Roane.
"They are!" said Huyghens warmly. "Just as normal as an honest dog!
They're not trained, like Semper. They train themselves!" He looked
back into the plate in his hands, which showed the ground five and six
and seven thousand feet higher. "Semper, now, is a trained bird without
too much brains. He's educated--a glorified hawk. But the bears want
to get along with men. They're emotionally dependent on us! Like dogs.
Semper's a servant, but they're companions and friends. He's trained,
but they're loyal. He's conditioned. They love us. He'd abandon me if
he ever realized he could--he thinks he can only eat what men feed him.
But the bears wouldn't want to. They like us. I admit that I like them.
Maybe because they like me."
Roane said deliberately:
"Aren't you a trifle loose-tongued, Huyghens? I'm a Colonial Survey
officer. I have to arrest you sooner or later. You've told me something
that will locate and convict the people who set you up here. It
shouldn't be hard to find where bears were bred for psychological
mutations, and where a bear named Kodius Champion left descendants! I
can find out where you came from now, Huyghens!"
Huyghens looked up from the plate with its tiny swaying television
image, relayed from where Semper floated impatiently in mid-air.
"No harm done," he said amiably. "I'm a criminal there, too. It's
officially on record that I kidnaped these bears and escaped with
them. Which, on my home planet, is about as heinous a crime as a man
can commit. It's worse than horse-theft back on Earth in the old days.
The kin and cousins of my bears are highly thought of. I'm quite a
criminal, back home."
Roane stared.
"Did you steal them?" he demanded.
"Confidentially," said Huyghens. "No. But prove it!" Then he said:
"Take a look in this plate. See what Semper can see up at the plateau's
edge."
* * * * *
Roane squinted aloft, where the eagle flew in great sweeps and dashes.
Somehow, by the experience of the past few days, Roane knew that Semper
was screaming fiercely as he flew. He made a dart toward the plateau's
border.
Roane looked at the transmitted picture. It was only four inches by
six, but it was perfectly without grain and in accurate color. It moved
and turned as the camera-bearing eagle swooped and circled. For an
instant the screen showed the steeply sloping mountainside, and off
at one edge the party of men and bears could be seen as dots. Then it
swept away and showed the top of the plateau.
There were sphexes. A pack of two hundred trotted toward the desert
interior. They moved at leisure, in the open. The viewing camera
reeled, and there were more. As Roane watched and as the bird flew
higher, he could see still other sphexes moving up over the edge of the
plateau from a small erosion-defile here and another one there. The
Sere Plateau was alive with the hellish creatures. It was inconceivable
that there should be game enough for them to live on. They were visible
as herds of cattle would be visible on grazing planets.
It was simply impossible.
"Migrating," observed Huyghens. "I said they did. They're headed
somewhere. Do you know, I doubt that it would be healthy for us to try
to cross the plateau through such a swarm of sphexes?"
Roane swore, in abrupt change of mood.
"But the signal's still coming through! Somebody's alive over at the
robot colony! Must we wait till the migration's over?"
"We don't know," Huyghens pointed out, "that they'll stay alive. They
may need help badly. We have to get to them. But at the same time--"
He glanced at Sourdough Charley and Sitka Pete, clinging patiently to
the mountainside while the men rested and talked. Sitka had managed to
find a place to sit down, though one massive paw anchored him in his
place.
Huyghens waved his arm, pointing in a new direction.
"Let's go!" he called briskly. "Let's go! Yonder! Hup!"
