<h2><SPAN name="CHAPTER_6" id="CHAPTER_6"></SPAN>CHAPTER 6</h2>
<p>It was nine o'clock at night when Lockley killed the porcupine, and
ten by the time Jill had gone back to sleep huddled between the
projecting roots of a giant tree. Shortly after midnight Lockley had
been awakened when a skunk defeated a hungry predator within a hundred
yards of their bivouac. But some time in between, there was another
happening of much greater importance elsewhere.</p>
<p>Something came out of Boulder Lake National Park. All humans had
supposedly fled from it. It was abandoned to the creatures of the
thing from the sky. But something came out of it.</p>
<p>Nobody saw the thing, of course. Nobody could approach it, which was
the point immediately dem<span class="pagenum"><SPAN name="Page_84" id="Page_84"></SPAN></span>onstrated. No human being could endure being
within seven miles of whatever it was. It was evidently a vehicle of
some sort, however, because it swung terror beams before it, and
terror beams on either side, and when it was clear of the Park it
played terror beams behind it, too. Men who suffered the lightest
touch of those sweeping beams of terror and anguish moved frantically
to avoid having the experience again. So when something moved out of
the Park and sent wavering terror beams before it, men moved to one
side or the other and gave it room.</p>
<p>On a large-scale map in the military area command post, its progress
could be watched as it was reported. The reports described a
development of unbearable beam strength which showed up as a bulge in
the cordon's roughly circular line. That bulge, which was the cordon
itself moving back, moved outward and became a half-circle some miles
across. It continued to move outward, and on the map it appeared like
a pseudopod extruded by an enormous amoeba. It was the area of
effectiveness of a weapon previously unknown on earth—the area where
humans could not stay.</p>
<p>Deliberately, the unseen moving thing severed itself from the similar
and larger weapon field which was its birthplace and its home. It
moved with great deliberation toward the small town of Maplewood,
twenty miles from the border of the Park.</p>
<p>Jeeps and motorcycles scurried ahead of it, just out of reach of its
beams. They made sure that houses and farms and all inhabited places
were emptied of people before the moving terror beams could engulf
them. They went into the town of Maplewood itself and frantically made
sure that nothing alive remained in it. They went on to clear the
countryside beyond.<span class="pagenum"><SPAN name="Page_85" id="Page_85"></SPAN></span></p>
<p>The unseen thing from the Park moved onward. High overhead there was a
dull muttering like faraway thunder, but it was planes with filled
bomb racks circling above the starlit land. There were men in those
planes who ached to dive down and destroy this separated fraction of
an invasion. But there were firm orders from the Pentagon. So long as
the invaders killed nobody, they were not to be attacked. There was
reason for the order in the desire of the government to be on friendly
terms with a race which could travel between the stars. But there was
an even more urgent reason. The aliens had not yet begun to murder,
but it was suspected that they had a horrifying power to kill. So it
was firmly commanded that no bomb or missile or bullet was to be used
unless the invaders invited hostilities by killing humans. Their
captives—the crew of a helicopter—might be freed if aliens and men
achieved friendship. So for now—no provocation!</p>
<p>The thing which nobody saw moved comfortably over the ground between
the park and Maplewood. In the center of the weapon field there was a
something which generated the terror beam and probably carried
passengers. Whatever it was, it moved onward and into Maplewood and
for seven miles in every direction troops watched for it to move out
again. Artillerymen had guns ready to fire upon it if they ever got
firing coordinates and permission to go into action. Planes were ready
to drop bombs if they ever got leave to do so. And a few miles away
there were rockets ready to prove their accuracy and devastating
capacity if only given a launching command. But nothing happened. Not
even a flare was permitted to be dropped by the planes far up in the
sky. A flare might be taken for hostility.</p>
<p>The thing from the Park stayed in Maplewood for<span class="pagenum"><SPAN name="Page_86" id="Page_86"></SPAN></span> two hours. At the end
of that time it moved deliberately back toward the Park. It left the
town untouched save for certain curious burglaries of hardware stores
and radio shops and a garage or two. It looked as if intensely curious
not-human beings had moved from their redoubt—Boulder Lake—to find
out what civilization human beings had attained. They could guess at
it by the buildings and the homes, but most notably in the technical
shops of the inhabitants.</p>
<p>It went slowly and deliberately back into the Park. Humans moved
cautiously back into the area that had been emptied. Not many, but
enough to be sure that the thing had really returned to the place from
which it had come. Soldiers were tentatively entering the
again-abandoned town of Maplewood when the unseen thing changed the
range of its weapon bearing on that little city. It was then
presumably not less than seven miles on its way back to Boulder Lake.
The military had congratulated themselves on what they'd learned. The
beam projectors at the lake had a range of much more than seven miles,
but this movable, unidentifiable thing carried a lesser armament. From
it, men and animals seven miles away were safe. This was notable news.</p>
<p>Then the unseen object did something. The terror beam that flicked
back and forth doubled in intensity. The soldiers just reentering
Maplewood smelled foulness and saw bright lights. Bellowings deafened
them. They fell with every muscle rigid in spasm. Beyond them other
men were paralyzed. For five minutes the invaders' mobile weapon
paralyzed all living things for a distance of fifteen miles. Then for
thirty seconds it paralyzed living things for a distance of thirty
miles. For a bare instant it convulsed men and animals for a greater
distance<span class="pagenum"><SPAN name="Page_87" id="Page_87"></SPAN></span> yet. And all these victims of the terror beam knew,
thereafter, an invincible horror of the beam.</p>
<p>The thing from the Park which nobody had seen went back into the Park.
And then men were permitted to return to exactly the same places
they'd been allowed to occupy before the thing began its excursion.</p>
<p>It seemed that nothing was changed, but everything was changed. If
there were mobile carriers of the invasion weapon, then victory could
not be had by a single atom bomb fired into Boulder Lake. There might
be a dozen separate mobile terror beam generators scattered through
the Park. Any atomic attack would need to be multiplied in its
violence to be certain of results. Instead of one bomb there might be
a need for fifty. They would have to destroy the Park utterly, even
its mountains. And the fallout from so many atom bombs simply could
not be risked. The invaders were effectively invulnerable.</p>
<p>While this undesirable situation was being demonstrated, Jill slept
heavily between two roots of a very large tree, and Lockley dozed
against a nearby tree trunk. He believed that he guarded Jill most
vigilantly.</p>
<p>He awoke at dawn with the din of bird song in his ears. Jill opened
her eyes at almost the same instant. She smiled at him and tried to
get up. She was stiff and sore from the hardness of the ground on
which she'd slept. But it was a new day, and there was breakfast. It
was porcupine cooked the night before.</p>
<p>"Somehow," said Jill as she nibbled at a bone, "somehow I feel more
cheerful than I did."</p>
<p>"That's a mistake," Lockley told her. "Start out with a few
premonitions and the day improves as they turn out wrong. But if you
start out hoping,<span class="pagenum"><SPAN name="Page_88" id="Page_88"></SPAN></span> the day ends miserably with most of your hopes
denied."</p>
<p>"You've got premonitions?" she asked.</p>
<p>"Definitely," he said.</p>
<p>It was true. As yet he knew nothing of last night's temporary
occupation of a human town, but he believed he knew how the terror
beam worked even if he couldn't figure out a way to generate it. He
could imagine no defense against it. But if Jill had awakened feeling
cheerful, there was no reason to depress her. She'd have reason enough
to be dejected later, beginning with proof of Vale's death and going
on from there.</p>
<p>"We might listen to the news," she suggested. "A premonition or two
might be ruled out right away!"</p>
<p>Silently, he turned on the little radio. Automatically, he set it for
the lowest volume they could hear distinctly.</p>
<p>The main item in the news was a baldly factual but toned-down report
of the thing from the lake which had left the park and examined a
small human town in detail and then had returned to the Park. There
were reports of peculiar hoofprints found where the invaders had been.
They were not the hoofprints of any earthly animal. There was an
optimistic report from the scientists at work on the problem of the
beam. Someone had come up with an idea and some calculations which
seemed to promise that the beam would presently be duplicated. Once it
was duplicated, of course a way to neutralize it could be found.</p>
<p>Lockley grunted. The broadcast was enthusiastic in its comments on the
scientists. It talked gobbledegook which sounded as if it meant
something but was actually nonsense. It barely touched on the fact
that human beings were now ordered out of a much larger space than had
been evacuated before. There<span class="pagenum"><SPAN name="Page_89" id="Page_89"></SPAN></span> was a statement from an important
official that panic buying of food was both unnecessary and unwise.
Lockley grunted again when the newscast ended.</p>
<p>"The idea that anything that can be duplicated can be canceled," he
announced gloomily, "is unfortunately rot. We can duplicate sounds,
but there's no way to make them cancel out! Not accurately!"</p>
<p>Jill had eaten a substantial part of the porcupine while the newscast
was on. It was not a satisfying breakfast, but it cheered her
immensely after two days of near-starvation.</p>
<p>"But," she observed, "maybe that won't apply to this business when you
report what you know. It's not likely that anybody else has stood just
outside a beam and made tests of what it's like and how it's aimed and
so on."</p>
<p>They started off. For journeying in the Park, Lockley had the
advantage that as part of the preparation for making a new map, he'd
familiarized himself with all mapping done to date. He knew very
nearly where he was. He knew within a close margin just where the
terror beam stretched. He'd smashed his watch, which during sunshine
substituted admirably for a compass, but he could maintain a
reasonably straight line toward that part of the Park's border the
terror beam would cross.</p>
<p>They moved doggedly over mountain-flanks and up valleys, and once they
followed a winding hollow for a long way because it led toward their
destination without demanding that they climb. It was in this area
that, pushing through brushwood beside a running stream, they came
abruptly upon a big brown bear. He was no more than a hundred feet
away. He stared at them inquisitively, raising his nose to sniff for
their scent.</p>
<p>Lockley bent and picked up a stone. He threw it.<span class="pagenum"><SPAN name="Page_90" id="Page_90"></SPAN></span> It clattered on
rocks on the ground. The bear made a whuffing sound and moved
aggrievedly away.</p>
<p>"I'd have been afraid to do that," said Jill.</p>
<p>"It was a he-bear," said Lockley. "I wouldn't have tried it on a
she-bear with cubs."</p>
<p>They went on and on. At mid-morning Lockley found some mushrooms. They
were insipid and only acute hunger would make them edible raw, but he
filled his pockets. A little later there were berries, and as they
gathered and ate them he lectured learnedly on edible wild plants to
be found in the wilderness. Jill listened with apparent interest. When
they left the berry patch they swung to the left to avoid a steep
climb directly in their way. And suddenly Lockley stopped short. At
the same instant Jill caught at his arm. She'd turned white.</p>
<p>They turned and ran.</p>
<p>A hundred yards back, Lockley slackened his speed. They stopped. After
a moment he managed to grin mirthlessly.</p>
<p>"A conditioned reflex," he said wryly. "We smell something and we run.
But I think it's the old familiar terror beam that crosses highways to
stop men from using them. If it were a portable beam projector with
somebody aiming it, we wouldn't be talking about it."</p>
<p>Jill panted, partly with relief.</p>
<p>"I've thought of something I want to try," said Lockley. "I should
have tried it yesterday when I first smashed my watch."</p>
<p>He retraced his steps to the spot where they'd caught the first whiff
of that disgusting reptilian-jungle-decay odor which had bombarded
their nostrils. Jill called anxiously, "Be careful!"</p>
<p>He nodded. He got the coiled bronze watchspring out of his pocket. He
went very cautiously to the spot where the smell became noticeable.
Standing well<span class="pagenum"><SPAN name="Page_91" id="Page_91"></SPAN></span> back from it, he tossed one end of the spring into it.
He drew it back. He repeated the operation. He moved to one side.
Again he swung the gold-colored ribbon. He dangled it back and forth.
Then he drew back yet again and wrapped his left hand and wrists with
many turns of the thin bronze spring, carefully spacing the turns. He
moved forward once more.</p>
<p>He came back, his expression showing no elation at all.</p>
<p>"No good," he said unhappily. "In a way, it works. The spring acts as
an aerial and picks up more of the beam than my hand. But I tried to
make a Faraday cage. That will stop most electromagnetic radiation,
but not this stuff! It goes right through, like electrons through a
radio tube grid."</p>
<p>He put the spring back in his pocket.</p>
<p>"Well," he grimaced. "Let's go on again. I had a little bit of hope,
but some smarter men than I am haven't got the right gimmick yet."</p>
<p>They started off once more. And this time they did not choose a path
for easier travel, but went up a steep slope that rose for hundreds of
feet to arrive at a crest with another steep slope going downhill. At
the top Lockley said sourly, "I did discover one thing, if it means
anything. The beam leaks at its edges, but it's only leakage. It
doesn't diffuse. It's tight. It's more like a searchlight beam than
anything else in that way. You can see a light beam at night because
dust motes scatter some part of it. But most of the light goes
straight on. This stuff does the same. It's hard to imagine a limit to
its range."</p>
<p>He trudged on downhill. Jill followed him. Presently, when they'd
covered two miles or more with no lightening of his expression, she
said, "You said you understand how it works. Radio and radar beams<span class="pagenum"><SPAN name="Page_92" id="Page_92"></SPAN></span>
don't have effects like this. How does this have them?"</p>
<p>"It makes high frequency currents on the surface of anything it hits.
High frequency doesn't go into flesh or metal. It travels on the
surface only. So when this beam hits a man it generates high frequency
on his skin. That induces counter currents underneath, and they
stimulate all the sensory nerves we've got—of our eyes and ears and
noses as well as our skin. Every nerve reports its own kind of
sensation. Run current over your tongue, and you taste. Induce a
current in your eyes, and you see flashes of light. So the beam makes
all our senses report everything they're capable of reporting, true or
not, and we're blinded and deafened. Then the nerves to our muscles
report to them that they're to contract, and they do. So we're
paralyzed."</p>
<p>"And," said Jill, "if there's a way to generate high frequency on a
man's skin there's nothing that can be done?"</p>
<p>"Nothing," said Lockley dourly.</p>
<p>"Maybe," said Jill, "you can figure out a way to prevent that high
frequency generation."</p>
<p>He shrugged. Jill frowned as she followed him. She hadn't forgotten
Vale, but she owed some gratitude to Lockley. Womanlike, she tried to
pay part of it by urging him to do something he considered impossible.</p>
<p>"At least," she suggested, "it can't be a death ray!"</p>
<p>Lockley looked at her.</p>
<p>"You're wrong there," he said coldly. "It can."</p>
<p>Jill frowned again. Not because of his statement, but because she
hadn't succeeded in diverting his mind from gloomy things. She had
reason enough for sadness, herself. If she spoke of it, Lockley would
try to encourage her. But he was concerned with<span class="pagenum"><SPAN name="Page_93" id="Page_93"></SPAN></span> more than his own
emotions. Without really knowing it, Jill had come to feel a great
confidence in Lockley. It had been reassuring that he could find food,
and perhaps more reassuring that he could chase away a bear. Such
talents were not logical reasons for being confident that he could
solve the alien's seemingly invincible weapon, but she was inclined to
feel so. And if she could encourage him to cope with the
monsters—why—it would be even a form of loyalty to Vale. So she
believed.</p>
<p>In the late afternoon Lockley said, "Another four or five miles and we
ought to be out of the Park and on another highway we'll hope won't be
blocked by a terror beam. Anyhow there should be an occasional
farmhouse where we can find some sort of civilized food."</p>
<p>Jill said hungrily, "Scrambled eggs!"</p>
<p>"Probably," he agreed.</p>
<p>They went on and on. Three miles. Four. Five. Five and a half. They
descended a minor slope and came to a hard-surfaced road with tire
marks on it and a sign sternly urging care in driving. There were
ploughed fields in which crops were growing. There was a row of stubby
telephone poles with a sagging wire between them.</p>
<p>"We'll head west," said Lockley. "There ought to be a farmhouse
somewhere near."</p>
<p>"And people," said Jill. "I look terrible!"</p>
<p>He regarded her with approval.</p>
<p>"No. You look all right. You look fine!"</p>
<p>It was pleasing that he seemed to mean it. But immediately she said,
"Maybe we'll be able to find out about ... about...."</p>
<p>"Vale," agreed Lockley. "But don't be disappointed if we don't. He
could have escaped or been freed without everybody knowing it."</p>
<p>She said in surprise, "Been freed! That's something<span class="pagenum"><SPAN name="Page_94" id="Page_94"></SPAN></span> I didn't think
of. He'd set to work to make them understand that we humans are
intelligent and they ought to make friends with us. That would be the
first thing he'd think of. And they might set him free to arrange it."</p>
<p>Lockley said, "Yes," in a carefully noncommittal tone.</p>
<p>Another mile, this time on the hard road. It seemed strange to walk on
so unyielding a surface after so many miles on quite different kinds
of footing. It was almost sunset now. There was a farmhouse set well
back from the road and barely discernable beyond nearby growing corn.
The house seemed dead. It was neat enough and in good repair. There
were clackings of chickens from somewhere behind it. But it had the
feel of emptiness.</p>
<p>Lockley called. He called again. He went to the door and would have
called once more, but the door opened at a touch.</p>
<p>"Evacuated," he said. "Did you notice that there was a telephone line
leading here from the road?"</p>
<p>He hunted in the now shadowy rooms. He found the telephone. He lifted
the receiver and heard the humming of the line. He tried to call an
operator. He heard the muted buzz that said the call was sounding. But
there was no answer. He found a telephone book and dialed one number
after another. Sheriff. Preacher. Doctor. Garage. Operator again.
General store.... He could tell that telephones rang dutifully in
remote abandoned places. But there was no answer at all.</p>
<p>"I'll look in the chicken coops," said Jill practically.</p>
<p>She came back with eggs. She said briefly, "The chickens were hungry.
I fed them and left the chicken yard gate open. I wonder if the beam
hurts them too?"<span class="pagenum"><SPAN name="Page_95" id="Page_95"></SPAN></span></p>
<p>"It does," said Lockley.</p>
<p>He made a light and then a fire and she cooked eggs which belonged to
the unknown people who owned this house and who had walked out of it
when instructions for immediate evacuation came. They felt queer,
making free with this house of a stranger. They felt that he might
come in and be indignant with them.</p>
<p>"I ought to wash the dishes," said Jill when they were finished.</p>
<p>"No," said Lockley. "We go on. We need to find some soldiers, or a
telephone that works...."</p>
<p>"I'm not a good dishwasher anyhow," said Jill guiltily.</p>
<p>Lockley put a banknote on the kitchen table, with a weight on it to
keep it from blowing away. They closed the house door. They'd eaten
fully and luxuriously of eggs and partly stale bread and the sensation
was admirable. They went out to the highway again.</p>
<p>"West is still our best bet," said Lockley. "They've blocked the
highway to eastward with that terror beam."</p>
<p>The sun had set now, but a fading glory remained in the sky. They saw
the slenderest, barest crescent of a new moon practically hidden in
the sunset glow. They walked upon a civilized road, with a fence on
one side of it and above it a single sagging telephone wire that could
be made out against the stars.</p>
<p>"I feel," said Jill, "as if we were almost safe, now. All this looks
so ordinary and reassuring."</p>
<p>"But we'd better keep our noses alert," Lockley told her. "We know
that one beam comes nearly this far and probably—no, certainly
crosses this road. There may be more."</p>
<p>"Oh, yes," agreed Jill. Then she said irrelevantly, "I'll bet they do
make him a sort of—ambassador<span class="pagenum"><SPAN name="Page_96" id="Page_96"></SPAN></span> to our government to arrange for
making friends. He'll be able to convince them!"</p>
<p>Again she referred to Vale. Lockley said nothing.</p>
<p>Night was now fully fallen. There were myriad stars overhead. They saw
the telephone wire dipping between poles against the sky's brightness.
They passed an open gate where another telephone wire led away,
doubtless to another farmhouse. But if there was no one at the other
end of a telephone line, there was no point in using a phone.</p>
<p>There came a rumbling noise behind them. They stared at one another in
the starlight. The rumbling approached.</p>
<p>"It—can't be!" said Jill, marvelling.</p>
<p>"It's a motor," said Lockley. He could not feel complete relief.
"Sounds like a truck. I wonder—"</p>
<p>He felt uneasiness. But it was absurd. Only human beings would use
motor trucks.</p>
<p>There was a glow in the distance behind them. It came nearer as the
sound of the motor approached. The motor's mutter became a grumble. It
was definitely a truck. They could hear those other sounds that trucks
always make in addition to their motor noises.</p>
<p>It came up to the curve they'd rounded last. Its headlight beams
glared on the cornstalks growing next to the highway. One headlight
appeared around the turn. Then the other. An enormous trailer-truck
combination came bumbling toward them. Jill held up her hand for it to
stop. Its headlights shone brightly upon her.</p>
<p>Airbrakes came on. The giant combination—cab in front, gigantic box
body behind—came to a halt. A man leaned out. He said amazedly, "Hey,
what are you folks doin' here? Everybody's supposed to be long gone!
Ain't you heard about all civilians clearing out from twenty miles
outside the Park? There's<span class="pagenum"><SPAN name="Page_97" id="Page_97"></SPAN></span> boogers in there! Characters from Mars or
somewhere. They eat people!"</p>
<p>Even in the starlight Lockley saw the familiar Wild Life Control
markings on the trailer. He heard Jill, her voice shaking with relief,
explaining that she'd been at the construction camp and had been left
behind, and that she and Lockley had made their way out.</p>
<p>"We want to get to a telephone," she added. "He has some information
he wants to give to the Army. It's very important." Then she
swallowed. "And I'd like to ask if you've heard anything about a Mr.
Vale. He was taken prisoner by the creatures up there. Have you heard
of his being released?"</p>
<p>The driver hesitated. Then he said, "No, ma'm. Not a word about him.
But we'll take care of you two! You musta been through plenty! Jud,
you go get in the trailer, back yonder. Make room for these two folks
up on the front seat." He added explanatorily, "There's cases and
stuff in the back, ma'm. You two folks climb right up here alongside
of me. You sure musta had a time!"</p>
<p>The door on the near side of the truck cab opened. A small man got
out. Silently, he went to the rear of the trailer and swung up out of
sight. Jill climbed into the opened door. Lockley followed her. He
still felt an irrational uneasiness, but he put it down to habit. The
past few days had formed it.</p>
<p>"We've been cartin' stuff for the soldiers," explained the driver as
Lockley closed the door behind him. "They keep track of where that
terror beam is workin', and they tell us by truck radio, and we dodge
it. Ain't had a bit of trouble. Never thought I'd play games with
Martians! Did you see any of 'em? What sort of critters are they?"</p>
<p>He slipped the truck into gear and gunned the motor. Truck and
trailer, together, began to roll<span class="pagenum"><SPAN name="Page_98" id="Page_98"></SPAN></span> down the highway. Lockley was
irritated with himself because he couldn't relax and feel safe, as
this development seemed to warrant.</p>
<p>Later, he would wonder why he hadn't used his head in this as in other
matters during the few days just past.</p>
<p>He plainly hadn't.</p>
