<h3><i>Invisible Assailants</i></h3>
<p>We did not locate the source of the bomb, and no others rose to assail
us. The mountain defiles, so far as our lights could illuminate them,
seemed deserted. We passed over the Divide, and on the plateau beyond,
we landed. A region of rolling country beneath its snow and ice. The
mountains came down sharply to the inner plain—a crescent of mountain
range stretching off into the dimness of distance, half encircling this
white plateau in the center of which stood the City of Ice. We could
just see it at the horizon, the glittering spires of its Ice Palace.</p>
<p>Around the city, completely enveloping it, was a thick circular wall of
ice twenty times the height of a man. We were too far away to see it
plainly—a turreted wall doubtless armed with projectors throughout its
circular length. Our finders would not show it, for it was insulated
against them. It stood there grey-white, bleak and apparently deserted.</p>
<p>Georg said: "It's the man's accursed inactivity! Is he going to do
nothing?... Our power plant has landed, Jac—there in the foothills—see
it drop?" A call from Rhaalton took his attention.</p>
<p>We landed our entire force in the foothills of the mountains. The power
plant was there; it looked like a squat industrial building set upon a
ledge of ice—a shining cliff-face behind it, a precipice in front. At
the foot of the precipice our other vehicles were clustered.</p>
<p>We were there throughout three entire times of sleep, hours strangely
the same in that unaltered polar twilight. During them, with the tower
platforms set in a ring about us to make an armed camp, we unloaded our
apparatus, erected our power controls, prepared the individual circuits,
making ready for our offensive. And still—though we, were alert for
it—no move from Tarrano.</p>
<p>They were hours during which, with my lack of technical knowledge, I
found myself often with nothing to do. Our camp was bustling with
activity, but among the now idle girls and many of the young men, there
was an air of gayety. They laughed, shouted, played games amid the rocks
from which we had long since melted the snow. Once, in what would have
been early evening had not the Sun in these latitudes held level like a
burned-out ball near the horizon, Elza and I wandered from the camp to
climb the cliffs nearby.</p>
<p>Beyond the circle of the camp's heat, the deadly cold of the region
assailed us. We had not wished to equip with the individual heating,
which for battle would leave us free of heavy garments; instead we
swathed ourselves in furs, with the exercise of climbing to aid us in
keeping warm.</p>
<p>It was wonderful to be again alone with Elza. Even with what was
impending we were young enough to put it momentarily from our minds.
Like young lovers clandestinely stealing away to a tryst, we left the
camp and hand in hand, climbed up amid the crags. A few hundred feet to
one side of the power house, and about the same distance above it, we
sat down at last to rest.</p>
<p>The scene from here was picturesque in the extreme. Across the flat,
shadowless snowy plain was the wall of ice with the city behind it. All
in the far distance, this city wherein our enemy was entrenched; and
there were no lights, no movement that we could see. In that drab
twilight, it seemed almost unreal.</p>
<p>The plain too, was empty. A few palpably deserted huts, nothing else.
Beneath us, snugly anchored there on the ledge, was our power house. No
unreality here. Its aerials were mounted; its external dynamos were
visibly revolving; from its windows blue shafts of light slanted out;
and from it rose the low hum of active power.</p>
<p>Below it, spread over the slightly sloping area of foothill beneath us,
lay our encampment. A ring of our tower vehicles, with their projectors
mounted and ready, their colored search-beams slowly sweeping the white
plain and the dead grey sky. Within their ring, the camp itself. Lighted
by the blue-white tubes set upon quadrupeds at intervals; heated by
strings of red-glowing wire and the red wire-balls used on Venus. The
snow and ice on the ground within the camp had melted, exposing the
naked rock.</p>
<p>A scene of blue and red lights and shifting shadows; bustling with
activity—figures, tiny from this height, hurrying about. The sounds
from it rose to us; the low hum and snap of the weapons being tested;
the shouted commands; and sometimes, mingled with it, the laughing shout
of a light-hearted girl.</p>
<p>Elza clung close to me. "Everything will be ready soon."</p>
<p>I nodded. "They're going to mount a ray up here on the cliff. Grolier
was telling me, for permanent protection—to stay here with the power
house when we go out to the attack."</p>
<p>Silent with her thoughts she did not answer me. Sidewise, I regarded her
solemn little face encased in its hood of fur. And then clumsily, for
our furs were heavy and awkward, I put my arm about her.</p>
<p>"I love you, Elza. It's worth a great deal to be here alone with you."</p>
<p>"Jac, what will he do?" Her gaze was to the far-off City of Ice. "It
seems so—so sinister, Jac, this silence from him. This inactivity. It
is not like him to be inactive."</p>
<p>"He's there," I said. "Rolltar the Mars man—boastful fellow,
blow-hard—he was telling some of us that in his opinion Tarrano had
already run away."</p>
<p>"Never!" she exclaimed. "This is his last stand. He'll make it
here—defeat us here—"</p>
<p>"Elza!"</p>
<p>She glanced momentarily at me, smiled a queer smile, and then gazed once
more over the distant plain. "I do not mean I think he'll defeat us,
Jac. I mean, that is his reasoning—make his last stand here—"</p>
<p>"He hasn't run away," I repeated. "I told Rolltar so. We got an outlaw
connection into the Ice Palace today. For a moment only, and then it was
discovered and broken off. But we had the image for a moment—it chanced
to show Tarrano himself. But he's isolated now. Bretan said his
isolation power—around the Ice Palace and the wall anyway—is greater
than any image-ray we can send against it."</p>
<p>My heart leaped suddenly, for I saw Elza's eyes widen, fear spring to
her face; heard the sharp intake of her breath, and felt her hand grip
my arm.</p>
<p>"Jac! There's something wrong! See there? And you hear it?"</p>
<p>From the instrument room I heard a vague drumming. A hiss, and then a
drumming growing louder. It was not a new sound, for now I remembered I
had been conscious of it for several moments past. Our encampment was
awake to it! A confusion down there; people running about; a figure
dashing wildly into the instrument room. And the aerials on the power
house began to snap viciously.</p>
<p>"Jac! What is it?"</p>
<p>"I don't know. See there, Elza? The sub-ray lights!"</p>
<p>The search-beams from our towers were inordinately active. Sweeping the
empty snow-plain and the empty sky. Empty? To my fevered imagination
they were peopled with enemies. And then one of the towers flashed on a
sub-ray—the dull infra-red for envisaging the slow rays below the power
of human sight. And another tower with its faint purple beam was using
the ultra-violet.</p>
<p>"That drumming, Elza! That's a microphone—the big one they just erected
near the instrument room. There's something coming! That's the magnified
sound of some distant rush of air. Very faint sound, but they must have
heard it on the ear-phones long ago. That microphone must have just been
connected—"</p>
<p>Something coming? We could see nothing.</p>
<p>"Let's go down, Jac! We must get back—"</p>
<p>"I've got infra-red glasses—" I fumbled beneath my furs. But I did not
have them.</p>
<p>"Jac—"</p>
<p>"Wait, Elza."</p>
<p>My glasses would have been useless, for the sub and ultra beams from the
towers were disclosing nothing. I could tell that by the hasty searching
sweeps they made. And then from the big Wilton tower, the newly
connected Zed-ray flashed on, I could hear the load of it in the
deepened, throaty hum from the power house. Its dirty brown beam sprayed
out over the plain; then swung to the sky, caught something, hung
motionless, narrowed into great intensity. The powerful Zed-ray,
capturing the visibility of dense solids only.<SPAN name="FNanchor_24_24" id="FNanchor_24_24"></SPAN><SPAN href="#Footnote_24_24" class="fnanchor">[24]</SPAN></p>
<p>There was something up there in the sky! The Zed-ray met resistance; we
could see the sparks, and hear the snap of them coming like a roar from
the microphone above the drumming. Met the resistance and conquered it;
gradually the snapping roar died away.</p>
<p>"Jac! I see something! Something there—don't you see it?"</p>
<p>A luminous blur became visible in the nearer sky—moving blobs of silver
luminosity in the mud-brown light of the Zed-ray. A hundred or more
moving silver blobs. They were taking form. The silvery phosphorescent
look faded, became grey-white. Took definite shape. Waving arms and
legs! Bones bereft of flesh. Human skeletons! Limbs waving rhythmically.
Bony arms, with fingers clutching metal weapons. Assailants coming at us
through the air, stripped by the Zed-ray of clothing, skin, flesh,
organs, to the naked bone. Skeletons with skulls of empty eye-sockets
and set jaw-bones to make the travesty of human faces grim with menace!</p>
