<p>There was no answer from the ground when breakout came and Calhoun
drove the Med Ship to a favourable position for a call. He patiently
repeated, over and over again, that the Med Ship <i>Aesclipus Twenty</i>
notified its arrival and requested coordinates for landing. He added
that its mass was fifty standard tons and that the purpose of its
visit was a planetary health inspection.</p>
<p>But there was no reply. There should have been a crisp description of
the direction from the planet's center at which, a certain time so
many hours or minutes later, the force-fields of the grid would find
it convenient to lock onto and lower the Med Ship. But the
communicator remained silent.</p>
<p>"There is a landing-grid," said Calhoun, frowning, "and if they're
using it to load fresh meat for Dara, from the herds I'm told about,
it should be manned. But they don't seem to intend to answer. Maybe
they think that if they pretend I'm not here I'll go away."</p>
<p>He reflected, and his frown deepened.</p>
<p>"If I didn't know what I know, I might. So if I land on emergency
rockets the blueskins down below may decide that I come from Weald.
And in that case it would be reasonable to blast me before I could
land and unload some fighting men. On the other hand, no ship from
Weald would conceiva<span class="pagenum"><SPAN name="Page_37" id="Page_37"></SPAN></span>bly land without impassioned assurance that it
was safe. It would drop bombs." He turned to the girl. "How many
Darians down below?"</p>
<p>She shook her head.</p>
<p>"You don't know," said Calhoun, "or won't tell, yet. But they ought to
be told about the arrival of that ship at Weald, and what Weald thinks
about it! My guess is that you came to tell them. It isn't likely that
Dara gets news directly from Weald. Where were you put ashore from
Dara, when you set out to be a spy?"</p>
<p>Her lips parted to speak, but she compressed them tightly. She shook
her head again.</p>
<p>"It must have been plenty far away," said Calhoun restlessly. "Your
people would have built a ship, and made fine forged papers for it,
and they'd travel so far from this part of space that when they landed
nobody would think of Dara. They'd use make-up to cover the blue
spots, but maybe it was so far away that blueskins had never been
heard of!"</p>
<p>Her face looked pinched, but she did not reply.</p>
<p>"Then they'd land half a dozen of you, with a supply of make-up for
the blue patches. And you'd separate, and take ships that went various
roundabout ways, and arrive on Weald one by one, to see what could be
done there to—" He stopped. "When did you find out positively that
there wasn't any plague any more?"</p>
<p>She began to grow pale.</p>
<p>"I'm not a mind reader," said Calhoun. "But it adds up. You're from
Dara. You've been on Weald. It's practically certain that there are
other ... agents, if you like that word better, on Weald. And there
hasn't been a plague on Weald so you people aren't carriers of it. But
you knew it in advance, I think. How'd you learn? Did a ship in some
sort of trouble land there, on Dara?"<span class="pagenum"><SPAN name="Page_38" id="Page_38"></SPAN></span></p>
<p>"Y—yes," said the girl. "We wouldn't let it go again. But the people
didn't catch—they didn't die. They lived—"</p>
<p>She stopped short.</p>
<p>"It's not fair to trap me!" she cried passionately. "It's not fair!"</p>
<p>"I'll stop," said Calhoun.</p>
<p>He turned to the control board. The Med Ship was only planetary
diameters from Orede, now, and the electron telescope showed shining
stars in leisurely motion across its screen. Then a huge, gibbous
shining shape appeared, and there were irregular patches of that muddy
color which is seabottom, and varicolored areas which were plains and
forests. Also there were mountains. Calhoun steadied the image, and
squinted at it.</p>
<p>"The mine," he observed, "was found by members of a hunting party,
killing wild cattle for sport."</p>
<p>Even a small planet has many millions of square miles of surface, and
a single human installation on a whole world will not be easy to find
by random search. But there were clues to this one. Men hunting for
sport would not choose a tropic nor an arctic climate to hunt in. So
if they found a mineral deposit, it would have been in a temperate
zone.</p>
<p>Cattle would not be found deep in a mountainous terrain. The mine
would not be on a prairie. The settlement on Orede, then, would be
near the edge of mountains, not far from a prairie such as wild cattle
would frequent, and it would be in a temperate climate.</p>
<p>Forested areas could be ruled out. And there would be a landing-grid.
Handling only one ship at a time, it might be a very small grid. It
could be only hundreds of yards across and less than half a mile high.
But its shadow would be distinctive.</p>
<p>Calhoun searched among low mountains near unforested<span class="pagenum"><SPAN name="Page_39" id="Page_39"></SPAN></span> prairie in a
temperate zone. He found a speck. He enlarged it manyfold. It was the
mine on Orede. There were heaps of tailings. There was something which
cast a long, lacy shadow: the landing-grid.</p>
<p>"But they don't answer our call," observed Calhoun, "so we go down
unwelcomed."</p>
<p>He inverted the Med Ship and the emergency rockets boomed. The ship
plunged planetward.</p>
<p>A long time later it was deep in the planet's atmosphere. The noise of
its rockets had become thunderous, with air to carry and to reinforce
the sound.</p>
<p>"Hold on to something, Murgatroyd," commanded Calhoun. "We may have to
dodge some ack."</p>
<p>But nothing came up from below. The Med Ship again inverted itself,
and its rockets pointed toward the planet and poured out pencil-thin,
blue-white, high-velocity flames. It checked slightly, but continued
to descend. It was not directly above the grid.</p>
<p>It swept downward until almost level with the peaks of the mountains
in which the mine lay. It tilted again, and swept onward over the
mountaintops, and then tilted once more and went racing up the valley
in which the landing-grid was plainly visible. Calhoun swung it on an
erratic course, lest there be opposition.</p>
<p>But there was no sign. Then the rockets bellowed, and the ship slowed
its forward motion, hovered momentarily, and settled to solidity
outside the framework of the grid. The grid was small, as Calhoun
reasoned. But it reached interminably toward the sky.</p>
<p>The rockets cut off. Slender as the flames had been, they'd melted and
bored thin drill-holes deep into the soil. Molten rock boiled and
bubbled down below. But there seemed no other sound. There was no
other motion. There was absolute<span class="pagenum"><SPAN name="Page_40" id="Page_40"></SPAN></span> stillness all around. But when
Calhoun switched on the outside microphones a faint, sweet melange of
high-pitched chirpings came from tiny creatures hidden under the
vegetation of the mountainsides.</p>
<p>Calhoun put a blaster in his pocket and stood up.</p>
<p>"We'll see what it looks like outside," he said with a certain
grimness. "I don't quite believe what the vision screens show."</p>
<p>Minutes later he stepped down to the ground from the Med Ship's exit
port. The ship had landed perhaps a hundred feet from what once had
been a wooden building. In it, ore from the mines was concentrated and
the useless tailings carried away by a conveyer belt to make a
monstrous pile of broken stone. But there was no longer a building.</p>
<p>Next to it there had been a structure containing an ore-crusher. The
massive machinery could still be seen, but the structure was in
fragments. Next to that, again, had been the shaft-head shelters of
the mine. They also were shattered practically to matchsticks.</p>
<p>The look of the ground about the building sites was simply and purely
impossible. It was a mass of hoofprints. Cattle by thousands and tens
of thousands had trampled everything. Cattle had burst in the wooden
sides of the buildings. Cattle had piled themselves up against the
beams upholding roofs until the buildings collapsed.</p>
<p>Then cattle had gone plunging over the wrecked buildings until there
was nothing left but indescribable chaos. Many, many cattle had died
in the crush. There were heaps of dead beasts about the metal girders
which were the foundation of the landing-grid. The air was tainted by
the smell of carrion.</p>
<p>The settlement had been destroyed, positively by stampeded cattle in
tens or hundreds of thousands charging blindly through and over and
upon it. Senselessly, they'd trampled each other to horrible
shapelessness. The mine shaft<span class="pagenum"><SPAN name="Page_41" id="Page_41"></SPAN></span> was not choked, because enormously
strong timbers had fallen across and blocked it. But everything else
was pure destruction.</p>
<p>Calhoun said evenly, "Clever! Very clever! You can't blame men when
beasts stampede. We should accept the evidence that some monstrous
herd, making its way through a mountain pass, somehow went crazy and
bolted for the plains. This settlement got in the way and it was too
bad for the settlement! Everything's explained, except the ship that
went to Weald.</p>
<p>"A cattle stampede, yes. Anybody can believe that! But there was a man
stampede. Men stampeded into the ship as blindly as the cattle
trampled down this little town. The ship stampeded off into space as
insanely as the cattle. But a stampede of men and cattle, in the same
place? That's a little too much!"</p>
<p>"But what—"</p>
<p>"How," asked Calhoun directly, "do you intend to get in touch with
your friends here?"</p>
<p>"I—I don't know," she said, distressed. "But if the ship stays here,
they're bound to come and see why. Won't they? Or will they?"</p>
<p>"If they're sane, they won't," said Calhoun. "The one undesirable
thing, here, would be human footprints on top of cattle tracks. If
your friends are a meat-getting party from Dara, as I believe, they
should cover up their tracks, get off-planet as fast as possible, and
pray that no signs of their former presence are ever discovered. That
would be their best first move, certainly!"</p>
<p>"What should I do?" she asked helplessly.</p>
<p>"I'm far from sure. At a guess, and for the moment, probably nothing.
I'll work something out. I've got the devil of a<span class="pagenum"><SPAN name="Page_42" id="Page_42"></SPAN></span> job before me,
though. I can't spend but so much time here."</p>
<p>"You can leave me here...."</p>
<p>He grunted and turned away. It was naturally unthinkable that he
should leave another human being on a supposedly uninhabited planet,
with the knowledge that it might actually be uninhabited, and the
future knowledge that any visitors would have the strongest of
possible reasons to hide themselves away.</p>
<p>He believed that there were Darians here, and the girl in the Med
ship, so he also believed, was also a Darian. But any who might be
hiding had so much to lose if they were discovered that they might be
hundreds or even thousands of miles from anywhere a space ship would
normally land—if they hadn't fled after the incident of the
spaceship's departure with its load of doomed passengers.</p>
<p>Considered detachedly, the odds were that there was again a food
shortage on Dara; that blueskins, in desperation, had raided or were
raiding or would raid the cattle herds of Orede for food to carry back
to their home planet; that somehow the miners on Orede had found that
they had blueskin neighbors, and died of the consequences of their
terror. It was a risky guess to make on such evidence as Calhoun
considered he had, but no other guess was possible.</p>
<p>If his guess were right, he was under some obligation to do exactly
what he believed the girl considered her mission—to warn all
blueskins that Weald would presently try to find them on Orede, when
all hell must break loose upon Dara for punishment. But if there were
men here, he couldn't leave a written warning for them in default of
friendly contact.</p>
<p>They might not find it, and a search party of Wealdians might. All he
could possibly do was try to make contact and give warning by such
means as would leave no evidence be<span class="pagenum"><SPAN name="Page_43" id="Page_43"></SPAN></span>hind that he'd done so. Weald
would consider a warning sure proof of blueskin guilt.</p>
<p>It was not satisfactory to be limited to broadcasts which might or
might not be picked up, and were unlikely to be acknowledged. But he
settled down with the communicator to make the attempt.</p>
<p>He called first on a GC wave length and form. It was unlikely that
blueskins would use general communication bands to keep in touch with
each other, but it had to be tried. He broadcast, tuned as broadly as
possible, and went up and down the GC spectrum, repeating his warning
painstakingly and listening without hope for a reply.</p>
<p>He did find one spot on the dial where there was re-radiation of his
message, as if from a tuned receiver. But he could not get a fix on
it: nobody might be listening. He exhausted the normal communication
pattern. Then he broadcast on old-fashioned amplitude modulation which
a modern communicator would not pick up at all, and which therefore
might be used by men in hiding.</p>
<p>He worked for a long time. Then he shrugged and gave it up. He'd
repeated to absolute tedium the facts that any Darians—blueskins—on
Orede ought to know. There'd been no answer. And it was all too likely
that if he'd been received, that those who heard him took his message
for a trick to discover if there were any hearers.</p>
<p>He clicked off at last and stood up, shaking his head. Suddenly the
Med Ship seemed empty. Then he saw Murgatroyd staring vexedly at the
exit port. The inner door of that small airlock was closed. The
telltale light said the outer door was not locked. Someone had gone
out quietly. The girl. Of course.</p>
<p>Calhoun said angrily, "How long ago, Murgatroyd?"</p>
<p>"<i>Chee!</i>" said Murgatroyd indignantly.<span class="pagenum"><SPAN name="Page_44" id="Page_44"></SPAN></span></p>
<p>It wasn't an answer, but it showed that Murgatroyd was vexed that he'd
been left behind. He and the girl were close friends, now. If she'd
left Murgatroyd in the ship when he wanted to go with her, then she
wasn't coming back.</p>
<p>Calhoun swore. He made certain she was not in the ship. He flipped the
outside-speaker switch and said curtly into the microphone, "Coffee!
Murgatroyd and I are having coffee. Will you come back, please?"</p>
<p>He repeated the call, and repeated it again. Multiplied as his voice
was by the speakers, she should hear him within a mile. She did not
appear. He went to a small and inconspicuous closet and armed himself.
A Med Ship man was not ever expected to fight, but there were
blast-rifles available for extreme emergency.</p>
<p>When he'd slung a power-pack over his shoulder and reached the
airlock, there was still no sign of his late stowaway. He stood in the
airlock door for long minutes, staring angrily about. Almost certainly
she wouldn't be looking in the mountains for men of Dara come here for
cattle. He used a pair of binoculars, first at low-magnification to
search as wide an area down-valley as possible, and then at highest
power to search the most likely routes.</p>
<p>He found a small, bobbing speck beyond a faraway hill crest. It was
her head. It went down below the hilltop.</p>
<p>He snapped a command to Murgatroyd, and when the <i>tormal</i> was on the
ground outside, he locked the port with that combination that nobody
but a Med Ship man was at all likely to discover or use.</p>
<p>"She's an idiot!" he told Murgatroyd sourly. "Come along! We've got to
be idiots too!"</p>
<p>He set out in pursuit.</p>
<p>There was blue sky overhead, as was inevitable on any
oxygen-atmosphere planet of a Sol-type yellow sun. There<span class="pagenum"><SPAN name="Page_45" id="Page_45"></SPAN></span> were
mountains, as is universal in planets whose surface rises and falls
and folds and bends from the effects of weather or vulcanism. There
were plants, as has come about wherever microorganisms have broken
down rock to a state where it can nourish vegetation. And naturally
there were animals.</p>
<p>There were even trees of severely practical design, and underbrush and
ground-cover equivalent to grass. There was, in short, a perfectly
predictable ecological system on Orede. The organic molecules involved
in life here would be made up of the same elements in the same
combinations as elsewhere where the same conditions of temperature and
moisture and sunshine obtained.</p>
<p>It was a distinctly Earthlike world, as it could not help but be, and
it was reasonable for cattle to thrive and increase here. Only men's
minds kept it from being a place where humans would thrive, too.</p>
<p>But only Calhoun would have considered the splintered settlement a
proof of that last.</p>
<p>The girl had a long start. Twice Calhoun came to places where she
could have chosen either of two ways onward. Each time he had to
determine which she'd followed. That cost time. Then the mountains
abruptly ended and a vast undulating plain stretched away to the
horizon. There were at least two large masses and many smaller clumps
of what could only be animals gathered together. Cattle.</p>
<p>But here the girl was plainly in view. Calhoun increased his stride.
He began to gain on her. She did not look behind.</p>
<p>Murgatroyd said "<i>Chee!</i>" in a complaining tone.</p>
<p>"I should have left you behind," agreed Calhoun dourly, "but there was
and is a chance I won't get back. You'll have to keep on hiking."</p>
<p>He plodded on. His memory of the terrain around the mining settlement
told him that there was no definite destina<span class="pagenum"><SPAN name="Page_46" id="Page_46"></SPAN></span>tion in the girl's mind.
But she was in no such despair as to want deliberately to be lost.
She'd guessed, Calhoun believed, that if there were Darians on the
planet, they'd keep the landing-grid under observation.</p>
<p>If they saw her leave that area and could see that she was alone, they
should intercept her to find out the meaning of the Med Ship's
landing. Then she could identify herself as one of them and give them
the terribly necessary warning of Weald's suspicions.</p>
<p>"But," said Calhoun sourly, "if she's right, they'll have seen me
marching after her now, which spoils her scheme. And I'd like to help
it, but the way she's going is too dangerous!"</p>
<p>He went down into one of the hollows of the uneven plain. He saw a
clump of a dozen or so cattle a little distance away. The bull looked
up and snorted. The cows regarded him truculently. Their air was not
one of bovine tranquility.</p>
<p>He was up the farther hillside and out of sight before the bull worked
himself up to a charge. Then Calhoun suddenly remembered one of the
items in the data about cattle he'd looked into just the other day. He
felt himself grow pale.</p>
<p>"Murgatroyd!" he said sharply. "We've got to catch up! Fast! Stay with
me if you can, but—" he was jog-trotting as he spoke—"even if you
get lost I have to hurry!"</p>
<p>He ran fifty paces and walked fifty paces. He ran fifty and walked
fifty. He saw her, atop a rolling of the ground. She came to a full
stop. He ran. He saw her turn to retrace her steps. He flung off the
safety of the blast-rifle and let off a roaring blast at the ground
for her to hear.</p>
<p>Suddenly she was fleeing desperately, toward him. He plunged on. She
vanished down into a hollow. Horns appeared over the hillcrest she'd
just left. Cattle appeared. Four, a dozen fifteen, twenty! They moved
ominously in her wake.</p>
<p>He saw her again, running frantically over another upward<span class="pagenum"><SPAN name="Page_47" id="Page_47"></SPAN></span> swell of
the prairie. He let off another blast to guide her. He ran on at top
speed with Murgatroyd trailing anxiously behind. From time to time
Murgatroyd called "<i>Chee-chee-chee!</i>" in frightened pleading not to be
abandoned.</p>
<p>More cattle appeared against the horizon. Fifty or a hundred. They
came after the first clump. The first group of a bull and his harem
were moving faster, now. The girl fled from them, but it is the
instinct of beef-cattle on the open range—Calhoun had learned it only
two days before—to charge any human they find on foot. A mounted man
to their dim minds is a creature to be tolerated or fled from, but a
human on foot is to be crushed and stamped and gored.</p>
<p>Those in the lead were definitely charging now, with heads bent low.
The bull charged furiously with shut eyes, as bulls do, but the cows,
many times more deadly, charged with their eyes wide open and wickedly
alert, and with a lumbering speed much greater than the girl could
manage.</p>
<p>She came up over the last rise, chalky-white and gasping, her hair
flying, in the last extremity of terror. The nearest of the pursuing
cattle were within ten yards when Calhoun fired from twenty yards
beyond. One creature bellowed as the blast-bolt struck.</p>
<p>It went down and others crashed into it and swept over it, and more
came on. The girl saw Calhoun now, and ran toward him, panting. He
knelt very deliberately and began to check the charge by shooting the
leading animals.</p>
<p>He did not succeed. There were more cattle following the first, and
more and more behind them. It appeared that all the cattle on the
plain joined in the blind and senseless charge. The thudding of hoofs
became a mutter and then a rumble and then a growl.</p>
<p>Plunging, clumsy figures rushed past on either side. But horns and
heads heaved up over the mound of animals Cal<span class="pagenum"><SPAN name="Page_48" id="Page_48"></SPAN></span>houn had shot. He shot
them too. More and more cattle came pounding past the rampart of his
victims, but always, it seemed, some elected to climb the heap of
their dead and dying fellows, and Calhoun shot and shot....</p>
<p>But he split the herd. The foremost animals had been charging a
sighted human enemy. Others had followed because it is the instinct of
cattle to join their running fellows in whatever crazed urgency they
feel. There was a dense, pounding, wailing, grunting, puffing, raising
thick and impenetrable clouds of dust which hid everything but
galloping beasts going past on either side.</p>
<p>It lasted for minutes. Then the thunder of hoofs diminished. It ended
abruptly, and Calhoun and the girl were left alone with the gruesome
pile of animals which had divided the charging herd into two parts.
They could see the rears of innumerable running animals, stupidly
continuing the charge, hardly different, now, from a stampede, whose
original objective none now remembered.</p>
<p>Calhoun thoughtfully touched the barrel of his blast-rifle and winced
at its scorching heat.</p>
<p>"I just realized," he said coldly, "that I don't know your name. What
is it?"</p>
<p>"Maril," said the girl. She swallowed. "Th—thank you."</p>
<p>"Maril," said Calhoun, "you are an idiot! It was half-witted at best
to go off by yourself! You could have been lost! You could have cost
me days of hunting for you, days badly needed for more important
matters!"</p>
<p>He stopped and took breath. "You may have spoiled what little chance
I've got to do something about the plans Weald's already making! You
have just acted with the most concentrated folly, and the most
magnificent imbecility that you or anybody else could manage!"</p>
<p>He said more bitterly still, "And I had to leave Murgatroyd<span class="pagenum"><SPAN name="Page_49" id="Page_49"></SPAN></span> behind to
get to you in time! He was right in the path of that charge!"</p>
<p>He turned away from her and said dourly, "All right! Come on back to
the ship. We'll go to Dara. We'd have to, anyhow. But Murgatroyd—"</p>
<p>Then he heard a very small sneeze. Out of a rolling wall of
still-roiling dust, Murgatroyd appeared forlornly. He was
dust-covered, and draggled, and his tail dropped, and he sneezed
again. He moved as if he could barely put one paw before another, but
at sight of Calhoun he sneezed yet again and said "<i>Chee!</i>" in a
disconsolate voice. Then he sat down and waited for Calhoun to come
and pick him up.</p>
<p>When Calhoun did so, Murgatroyd clung to him pathetically and said
"<i>Chee-chee!</i>" and again "<i>Chee-chee!</i>" with the intonation of one
telling of incredible horrors and disasters endured. And as a matter
of fact the escape of a small animal like Murgatroyd was remarkable.
He'd escaped the trampling hoofs of at least hundreds of charging
animals. Luck must have played a great part in it, but an hysterical
agility in dodging must have been required, too.</p>
<p>Calhoun headed back for the valley where the settlement had been, and
the Med Ship was. Murgatroyd clung to his neck. The girl Maril
followed discouragedly. She was at that age when girls—and men of
corresponding type—can grow most passionately devoted to ideals or
causes in default of a promising personal romance. When concerned with
such causes they become splendidly confident that whatever they decide
to do is sensible if only it is dramatic. But Maril was shaken, now.</p>
<p>Calhoun did not speak to her again. He led the way. A mile back toward
the mountains, they began to see stragglers from the now-vanished
herd. A little farther, those stragglers began to notice them. It
would have been a matter of no<span class="pagenum"><SPAN name="Page_50" id="Page_50"></SPAN></span> moment if they'd been domesticated
dairy cattle, but these were range cattle gone wild. Twice, Calhoun
had to use his blast-rifle to discourage incipient charges by
irritated bulls or even more irritated cows. Those with calves darkly
suspected Calhoun of designs upon their offspring.</p>
<p>It was a relief to enter the valley again. But it was two miles more
to the landing-grid with the Med Ship beside it and the reek of
carrion in the air.</p>
<p>They were perhaps two hundred feet from the ship when a blast-rifle
crashed and its bolt whined past Calhoun so close that he felt the
monstrous heat. There had been no challenge. There was no warning.
There was simply a shot which came horribly close to ending Calhoun's
career in a completely arbitrary fashion.</p>
