<h2>CHAPTER IV</h2>
<h3>A Han Air Raid</h3>
<p class="cap"><span class="dcap">There</span> was a girl in Wilma's camp named Gerdi
Mann, with whom Bill Hearn was desperately in
love, and the four of us used to go around a lot
together. Gerdi was a distinct type. Whereas Wilma
had the usual dark brown hair and hazel eyes that
marked nearly every member of the community, Gerdi
had red hair, blue eyes and very fair skin. She has
been dead many years now, but I remember her vividly
because she was a throwback in physical appearance to
a certain 20th Century type which I have found very
rare among modern Americans; also because the four
of us were engaged one day in a discussion of this very
point, when I obtained my first experience of a Han
air raid.</p>
<p>We were sitting high on the side of a hill overlooking
the valley that teemed with human activity, invisible
beneath its blanket of foliage.</p>
<p>The other three, who knew of the Irish but vaguely
and indefinitely, as a race on the other side of the globe,
which, like ourselves, had succeeded in maintaining a
precarious and fugitive existence in rebellion against the
Mongolian domination of the earth, were listening with
interest to my theory that Gerdi's ancestors of several
hundred years ago must have been Irish. I explained
that Gerdi was an Irish type, evidently a throwback,
and that her surname might well have been McMann,
or McMahan, and still more anciently "mac Mathghamhain."
They were interested too in my surmise that
"Gerdi" was the same name as that which had been
"Gerty" or "Gertrude" in the 20th Century.</p>
<p>In the middle of our discussion, we were startled
by an alarm rocket that burst high in the air, far to the
north, spreading a pall of red smoke that drifted like
a cloud. It was followed by others at scattered points
in the northern sky.</p>
<p>"A Han raid!" Bill exclaimed in amazement. "The
first in seven years!"</p>
<p>"Maybe it's just one of their ships off its course,"
I ventured.</p>
<p>"No," said Wilma in some agitation. "That would
be green rockets. Red means only one thing, Tony.
They're sweeping the countryside with their dis beams.
Can you see anything, Bill?"</p>
<p>"We had better get under cover," Gerdi said nervously.
"The four of us are bunched here in the open.
For all we know they may be twelve miles up, out of
sight, yet looking at us with a projecto'."</p>
<p>Bill had been sweeping the horizon hastily with his
glass, but apparently saw nothing.</p>
<p>"We had better scatter, at that," he said finally. "It's
orders, you know. See!" He pointed to the valley.</p>
<p>Here and there a tiny human figure shot for a moment
above the foliage of the treetops.</p>
<p>"That's bad," Wilma commented, as she counted the
jumpers. "No less than fifteen people visible, and all
clearly radiating from a central point. Do they want
to give away our location?"</p>
<p>The standard orders covering air raids were that the
population was to scatter individually. There should
be no grouping, or even pairing, in view of the destructiveness
of the disintegrator rays. Experience of generations
had proved that if this were done, and everybody
remained hidden beneath the tree screens, the
Hans would have to sweep mile after mile of territory,
foot by foot, to catch more than a small percentage of
the community.</p>
<p>Gerdi, however, refused to leave Bill, and Wilma
developed an equal obstinacy against quitting my side.
I was inexperienced at this sort of thing, she explained,
quite ignoring the fact that she was too; she was only
thirteen or fourteen years old at the time of the last
air raid.</p>
<p>However, since I could not argue her out of it, we
leaped together about a quarter of a mile to the right,
while Bill and Gerdi disappeared down the hillside
among the trees.</p>
<p>Wilma and I both wanted a point of vantage from
which we might overlook the valley and the sky to the
north, and we found it near the top of the ridge, where,
protected from visibility by thick branches, we could
look out between the tree trunks, and get a good view
of the valley.</p>
<p>No more rockets went up. Except for a few of those
warning red clouds, drifting lazily in a blue sky, there
was no visible indication of man's past or present
existence anywhere in the sky or on the ground.</p>
<p>Then Wilma gripped my arm and pointed. I saw
it; away off in the distance; looking like a phantom
dirigible airship, in its coat of low-visibility paint, a
bare spectre.</p>
<p>"Seven thousand feet up," Wilma whispered, crouching
close to me. "Watch."</p>
<p>The ship was about the same shape as the great
dirigibles of the 20th Century that I had seen, but
without the suspended control car, engines, propellors,
rudders or elevating planes. As it loomed rapidly
nearer, I saw that it was wider and somewhat flatter
than I had supposed.</p>
<p>Now I could see the repellor rays that held the ship
aloft, like searchlight beams faintly visible in the bright
daylight (and still faintly visible to the human eye at
night). Actually, I had been informed by my instructors,
there were two rays; the visible one generated by
the ship's apparatus, and directed toward the ground
as a beam of "carrier" impulses; and the true repellor
ray, the complement of the other in one sense, induced
by the action of the "carrier" and reacting in a concentrating
upward direction from the mass of the earth,
becoming successively electronic, atomic and finally
molecular, in its nature, according to various ratios of
distance between earth mass and "carrier" source,
until, in the last analysis, the ship itself actually is
supported on an upward rushing column of air, much
like a ball continuously supported on a fountain jet.</p>
<p>The raider neared with incredible speed. Its rays
were both slanted astern at a sharp angle, so that it slid
forward with tremendous momentum.</p>
<p>The ship was operating two disintegrator rays,
though only in a casual, intermittent fashion. But whenever
they flashed downward with blinding brilliancy,
forest, rocks and ground melted instantaneously into
nothing, where they played upon them.</p>
<p>When later I inspected the scars left by these rays
I found them some five feet deep and thirty feet wide,
the exposed surfaces being lava-like in texture, but of
a pale, iridescent, greenish hue.</p>
<p>No systematic use of the rays was made by the ship,
however, until it reached a point over the center of
the valley—the center of the community's activities.
There it came to a sudden stop by shooting its repellor
beams sharply forward and easing them back gradually
to the vertical, holding the ship floating and motionless.
Then the work of destruction began systematically.</p>
<p>Back and forth traveled the destroying rays, ploughing
parallel furrows from hillside to hillside. We
gasped in dismay, Wilma and I, as time after time we
saw it plough through sections where we knew camps
or plants were located.</p>
<p>"This is awful," she moaned, a terrified question in
her eyes. "How could they know the location so exactly,
Tony? Did you see? They were never in doubt. They
stalled at a predetermined spot—and—and it was exactly
the right spot."</p>
<p>We did not talk of what might happen if the rays
were turned in our direction. We both knew. We
would simply disintegrate in a split second into mere
scattered electronic vibrations. Strangely enough, it
was this self-reliant girl of the 25th Century, who clung
to me, a relatively primitive man of the 20th, less
familiar than she with the thought of this terrifying
possibility, for moral support.</p>
<p>We knew that many of our companions must have
been whisked into absolute non-existence before our
eyes in these few moments. The whole thing paralyzed
us into mental and physical immobility for I do not
know how long.</p>
<p>It couldn't have been long, however, for the rays had
not ploughed more than thirty of their twenty-foot
furrows or so across the valley, when I regained control
of myself, and brought Wilma to herself by shaking
her roughly.</p>
<p>"How far will this rocket gun shoot, Wilma?" I
demanded, drawing my pistol.</p>
<p>"It depends on your rocket, Tony. It will take even
the longest range rocket, but you could shoot more
accurately from a longer tube. But why? You
couldn't penetrate the shell of that ship with rocket
force, even if you could reach it."</p>
<p>I fumbled clumsily with my rocket pouch, for I was
excited. I had an idea I wanted to try; a "hunch" I
called it, forgetting that Wilma could not understand
my ancient slang. But finally, with her help, I selected
the longest range explosive rocket in my pouch, and
fitted it to my pistol.</p>
<p>"It won't carry seven thousand feet, Tony," Wilma
objected. But I took aim carefully. It was another
thought that I had in my mind. The supporting repellor
ray, I had been told, became molecular in character
at what was called a logarithmic level of five (below
that it was a purely electronic "flow" or pulsation between
the source of the "carrier" and the average mass
of the earth). Below that level if I could project my
explosive bullet into this stream where it began to carry
material substance upward, might it not rise with the
air column, gathering speed and hitting the ship with
enough impact to carry it through the shell? It was
worth trying anyhow. Wilma became greatly excited,
too, when she grasped the nature of my inspiration.</p>
<p>Feverishly I looked around for some formation of
branches against which I could rest the pistol, for I
had to aim most carefully. At last I found one.
Patiently I sighted on the hulk of the ship far above us,
aiming at the far side of it, at such an angle as would,
so far as I could estimate, bring my bullet path through
the forward repellor beam. At last the sights wavered
across the point I sought and I pressed the button
gently.</p>
<p>For a moment we gazed breathlessly.</p>
<p>Suddenly the ship swung bow down, as on a pivot,
and swayed like a pendulum. Wilma screamed in her
excitement.</p>
<p>"Oh, Tony, you hit it! You hit it! Do it again;
bring it down!"</p>
<p>We had only one more rocket of extreme range between
us, and we dropped it three times in our excitement
in inserting it in my gun. Then, forcing myself
to be calm by sheer will power, while Wilma stuffed
her little fist into her mouth to keep from shrieking,
I sighted carefully again and fired. In a flash, Wilma
had grasped the hope that this discovery of mine might
lead to the end of the Han domination.</p>
<p>The elapsed time of the rocket's invisible flight
seemed an age.</p>
<p>Then we saw the ship falling. It seemed to plunge
lazily, but actually it fell with terrific acceleration,
turning end over end, its disintegrator rays, out of control,
describing vast, wild arcs, and once cutting a gash
through the forest less than two hundred feet from
where we stood.</p>
<p>The crash with which the heavy craft hit the ground
reverberated from the hills—the momentum of eighteen
or twenty thousand tons, in a sheer drop of seven
thousand feet. A mangled mass of metal, it buried
itself in the ground, with poetic justice, in the middle
of the smoking, semi-molten field of destruction it had
been so deliberately ploughing.</p>
<p>The silence, the vacuity of the landscape, was oppressive,
as the last echoes died away.</p>
<p>Then far down the hillside, a single figure leaped
exultantly above the foliage screen. And in the distance
another, and another.</p>
<p>In a moment the sky was punctured by signal rockets.
One after another the little red puffs became drifting
clouds.</p>
<p>"Scatter! Scatter!" Wilma exclaimed. "In half an
hour there'll be an entire Han fleet here from Nu-yok,
and another from Bah-flo. They'll get this instantly
on their recordographs and location finders. They'll
blast the whole valley and the country for miles beyond.
Come, Tony. There's no time for the gang to
rally. See the signals. We've got to jump. Oh, I'm
so proud of you!"</p>
<p>Over the ridge we went, in long leaps toward the
east, the country of the Delawares.</p>
<p>From time to time signal rockets puffed in the sky.
Most of them were the "red warnings," the "scatter"
signals. But from certain of the others, which Wilma
identified as Wyoming rockets, she gathered that whoever
was in command (we did not know whether the
Boss was alive or not) was ordering an ultimate rally
toward the south, and so we changed our course.</p>
<p>It was a great pity, I thought, that the clan had not
been equipped throughout its membership with ultrophones,
but Wilma explained to me, that not enough
of these had been built for distribution as yet, although
general distribution had been contemplated within a
couple of months.</p>
<p>We traveled far before nightfall overtook us, trying
only to put as much distance as possible between ourselves
and the valley.</p>
<p>When gathering dusk made jumping too dangerous,
we sought a comfortable spot beneath the trees, and
consumed part of our emergency rations. It was the
first time I had tasted the stuff—a highly nutritive synthetic
substance called "concentro," which was, however,
a bit bitter and unpalatable. But as only a mouthful
or so was needed, it did not matter.</p>
<p>Neither of us had a cloak, but we were both
thoroughly tired and happy, so we curled up together
for warmth. I remember Wilma making some sleepy
remark about our mating, as she cuddled up, as though
the matter were all settled, and my surprise at my own
instant acceptance of the idea, for I had not consciously
thought of her that way before. But we both fell asleep
at once.</p>
<p>In the morning we found little time for love making.
The practical problem facing us was too great. Wilma
felt that the Wyoming plan must be to rally in the
Susquanna territory, but she had her doubts about the
wisdom of this plan. In my elation at my success in
bringing down the Han ship, and my newly found interest
in my charming companion, who was, from my
viewpoint of another century, at once more highly civilized
and yet more primitive than myself, I had forgotten
the ominous fact that the Han ship I had
destroyed must have known the exact location of the
Wyoming Works.</p>
<p>This meant, to Wilma's logical mind, either that the
Hans had perfected new instruments as yet unknown
to us, or that somewhere, among the Wyomings or
some other nearby gang, there were traitors so degraded
as to commit that unthinkable act of trafficking
in information with the Hans. In either contingency,
she argued, other Han raids would follow, and since
the Susquannas had a highly developed organization
and more than usually productive plants, the next raid
might be expected to strike them.</p>
<p>But at any rate it was clearly our business to get in
touch with the other fugitives as quickly as possible,
so in spite of muscles that were sore from the excessive
leaping of the day before, we continued on our way.</p>
<p>We traveled for only a couple of hours when we
saw a multi-colored rocket in the sky, some ten miles
ahead of us.</p>
<p>"Bear to the left, Tony," Wilma said, "and listen
for the whistle."</p>
<p>"Why?" I asked.</p>
<p>"Haven't they given you the rocket code yet?" she
replied. "That's what the green, followed by yellow
and purple means; to concentrate five miles east of
the rocket position. You know the rocket position
itself might draw a play of disintegrator beams."</p>
<p>It did not take us long to reach the neighborhood of
the indicated rallying, though we were now traveling
beneath the trees, with but an occasional leap to a top
branch to see if any more rocket smoke was floating
above. And soon we heard a distant whistle.</p>
<p>We found about half the Gang already there, in a
spot where the trees met high above a little stream.
The Big Boss and Raid Bosses were busy reorganizing
the remnants.</p>
<p>We reported to Boss Hart at once. He was silent,
but interested, when he heard our story.</p>
<p>"You two stick close to me," he said, adding grimly,
"I'm going back to the valley at once with a hundred
picked men, and I'll need you."</p>
