<h2> CHAPTER VII </h2>
<h3> The Return to Ganymede </h3>
<p class="first">
<span class="drop">"M</span><span class="up">ust</span> you you go back to Ganymede?" Barkovis asked, slowly and
thoughtfully. He was sitting upon a crystal bench beside the fountain,
talking with Stevens, who, dressed in his bulging space-suit, stood near
an airlock of the <i>Forlorn Hope</i>. "It seems a shame that you should face
again those unknown, monstrous creatures who so inexcusably attacked us
both without provocation."</p>
<p>"I'm not so keen on it myself, but I can't see any other way out of it,"
the Terrestrial replied. "We left a lot of our equipment there, you
know; and even if I should build duplicates here, it wouldn't do us any
good. These ten-nineteens are the most powerful transmitting tubes known
when we left Tellus, but even their fields, dense as they are, can't
hold an ultra-beam together much farther than about six astronomical
units. So you see we can't possibly reach our friends from here with
this tube; and your system of beam transmission won't hold anything
together even that far, and won't work on any wave shorter than Roeser's
Rays. We may run into some more of those little spheres, though, and I
don't like the prospect. I wonder if we couldn't plate a layer of that
mirror of yours upon the <i>Hope</i> and carry along a few of those bombs? By
the way, what is that explosive—or is it something beyond Tellurian
chemistry?"</p>
<p>"Its structure should be clear to you, although you probably could not
prepare it upon Tellus because of your high temperature. It is nothing
but nitrogen—twenty-six atoms of nitrogen combined to form one molecule
of what you would call—N-twenty-six?"</p>
<p>"Wow!" Stevens whistled. "Crystalline, pentavalent nitrogen—no wonder
it's violent!"</p>
<p>"We could, of course, cover your vessel with the mirror, but I am afraid
that it would prove of little value. The plates are so hot that it would
soon volatilize."</p>
<p>"Not necessarily," argued Stevens. "We could live in number one
life-boat, and shut off the heat everywhere else. The life-boats are
insulated from the structure proper, and the inner and outer walls of
the structure are insulated from each other. With only the headquarters
lifeboat warm, the outer wall could be held pretty close to zero
absolute."</p>
<p>"That is true. The bombs, of course, are controlled by radio, and
therefore may be attached to the outer wall of your vessel. We shall be
glad to do these small things for you."</p>
<p>The heaters of the <i>Forlorn Hope</i> were shut off, and as soon as the
outer shell had cooled to Titanian temperature, a corps of mechanics set
to work. A machine very like a concrete mixer was rolled up beside the
steel vessel, and into its capacious maw were dumped boxes and barrels
of dry ingredients and many cans of sparkling liquid. The resultant
paste was pumped upon the steel plating in a sluggish, viscid stream,
which spread out into a thick and uniform coating beneath the flying
rollers of the skilled Titanian workmen. As it hardened, the paste
smoothed magically into the perfect mirror which covered the
space-vessels of the satellite; and a full dozen of the mirror explosive
bombs of this strange people were hung in the racks already provided.</p>
<p>"Once again I must caution you concerning those torpedoes," Barkovis
warned Stevens. "If you use them all, very well, but do not try to take
even one of them into any region where it is very hot, for it will
explode and demolish your vessel. If you do not use them, destroy them
before you descend into the hot atmosphere of Ganymede. The mirror will
volatilize harmlessly at the temperature of melting mercury, but the
torpedoes must be destroyed. Once more, Tellurians, we thank you for
what you have done, and wish you well."</p>
<p>"Thanks a lot for <i>your</i> help—we still owe you something," replied
Stevens. "If either of your power-plants go sour on you again, or if
you need any more built, be sure to let us know—you can come close
enough to the inner planets now on your own beam to talk to us on the
ultra-communicator. We'll be glad to help you any way we can—and we may
call on you for help again. Goodbye, Barkovis—goodbye, all Titania!"</p>
<p>He made his way through the bitterly cold shop into the control-room of
their lifeboat, and while he was divesting himself of his heavy suit,
Nadia lifted the <i>Forlorn Hope</i> into the blue-green sky of Titan,
accompanied by an escort of the mirrored globes. Well clear of the
atmosphere of the satellite, the terrestrial cruiser shot forward at
normal acceleration, while the Titanian vessels halted and wove a
pattern of blue and golden rays in salute to the departing guests.</p>
<p>"Well, Nadia, we're off—on a long trek, too."</p>
<p>"Said Wun Long Hop, the Chinese pee-lo," Nadia agreed. "Sure
everything's all x, big boy?"</p>
<p>"To nineteen decimals," he declared. "You couldn't squeeze another frank
into our accumulators with a proof-bar, and since they're sending us all
the power we want to draw, we won't need to touch our batteries or tap
our own beam until we're almost to Jupiter. To cap the climax, what it
takes to make big medicine on those spherical friends of ours, we've
got. We're not sitting on top of the world, ace—we've perched exactly
at the apex of the entire universe!"</p>
<p>"How long is it going to take?"</p>
<p>"Don't know. Haven't figured it yet, but it'll be <i>beaucoup</i> days," and
the two wanderers from far-distant Earth settled down to the routine of
a long and uneventful journey.</p>
<p>They gave Saturn and his spectacular rings a wide berth and sped on,
with ever-increasing velocity. Past the outer satellites, on and on,
the good ship <i>Forlorn Hope</i> flew into the black-and-brilliant depths of
interplanetary space. Saturn was an ever-diminishing disk beneath them:
above them was Jupiter's thin crescent, growing ever larger and more
bright, and the Monarch of the Solar System, remaining almost stationary
day after day, increasing steadily in apparent diameter and in
brilliance.</p>
<p class="first">
<span class="drop">A</span><span class="up">lthough</span> the voyage from Titan to Ganymede was long, it was not
monotonous, for there was much work to be done in the designing and
fabrication of the various units which were to comprise the ultra-radio
transmitting station. In the various compartments of the <i>Forlorn Hope</i>
there were sundry small motors, blowers, coils, condensers, force-field
generators, and other items which Stevens could use with little or no
alteration; but for the most part he had to build everything himself.
Thus it was that time passed quickly; so quickly that Jupiter loomed
large and the Saturnian beam of power began to attenuate almost before
the Terrestrials realized that their journey was drawing to an end.</p>
<p>"Our beam's falling apart fast," Stevens read his meters carefully, then
swung his communicator beam toward Jupiter. "We aren't getting quite
enough power to hold our acceleration at normal—think I'll cut now,
while we're still drawing enough to let the Titanians know we're off
their beam. We've got lots of power of our own now; and we're getting
pretty close to enemy territory, so they may locate that heavy beam.
Have you found Ganymede yet?"</p>
<p>"Yes, it will be on the other side of Jupiter by the time we get there.
Shall I detour, or put on a little more negative and wait for it to come
around to this side?"</p>
<p>"Better wait, I think. The farther away we stay from Jupiter and the
major satellites, the better."</p>
<p>"All x—it's on. Suppose we'd better start standing watches, in case
some of them show up?"</p>
<p>"No use," he dissented. "I've been afraid to put out our
electro-magnetic detectors, as they could surely trace them in use.
Without them, we couldn't spot an enemy ship even if we were looking
right at it, except by accident; since they won't be lighted up and
it's awfully hard to see anything out here, anyway. We probably won't
know they're within a million kilometers until they put a beam on us.
Barkovis says that this mirror will reflect any beam they can use, and
I've already got a set of photo-cells in circuit to ring an alarm at
the first flash off of our mirror plating. I'd like to get in the first
licks myself, but I haven't been able to dope out any way of doing it.
So you might as well sleep in your own room, as usual, and I'll camp
here right under the panel until we get to Ganymede. There's a couple
of little things I just thought of, though, that may help some; and
I'm going to do 'em right now."</p>
<p>Putting on his space-suit, he picked up a power drill and went out into
the bitter cold of the outer structure. There he attacked the inner
wall of their vessel, and the carefully established inter-wall vacuum
disappeared in a screaming hiss of air as the tempered point bit through
plate after plate.</p>
<p>"What's the idea, Steve?" Nadia asked, when he had re-entered the
control room. "Now you'll have all that pumping to do over again."</p>
<p>"Protection for the mirrors," he explained. "You see, they aren't
perfect reflectors. There's a little absorption, so that some stuff
comes through. Not much, of course; but enough to kill some of those
Titanians and almost enough to ruin their ship got through in about ten
minutes, and only one enemy was dealing it out. We can stand more than
they could, of course, but the mirror itself won't stand much more heat
than it was absorbing then. But with air in those spaces instead of
vacuum, and with the whole mass of the <i>Hope</i>, except this one lifeboat,
as cold as it is, I figure that there'll be enough conduction and
convection through them to keep the outer wall and the mirror cold—cool
enough, at least, to hold the mirror on for an hour. If only one ship
tackles us, it won't be bad—but I figure that if there's only one,
we're lucky."</p>
<p class="first">
<span class="drop">S</span><span class="up">tevens'</span> fears were only too well grounded, for during the "evening" of
the following day, while he was carefully scanning the heavens for some
sign of enemy craft, the alarm bell over his head burst into its brazen
clamor. Instantly he shot out the detectors and ultra-lights and saw not
one, but six of the deadly globes—almost upon them, at point-blank
range! One was already playing a beam of force upon the <i>Forlorn Hope</i>,
and the other five went into action immediately upon feeling the
detector impulses and perceiving that the weapon of their sister ship
had encountered an unusual resistance in the material of that peculiarly
mirrored wedge. As those terrific forces struck her, the terrestrial
cruiser became a vast pyrotechnic set piece, a dazzling fountain of
coruscant brilliance: for the mirror held. The enemy beams shot back
upon themselves and rebounded in all directions, in the same spectacular
exhibition of frenzied incandescence which had marked the resistance of
the Titanian sphere to a similar attack.</p>
<p>But Stevens was not idle. In the instant of launching his detectors,
as fast as he could work the trips, four of the frightful nitrogen
bombs of Titan—all that he could handle at once—shot out into space,
their rocket-tubes flaring viciously. The enemy detectors of course
located the flying torpedoes immediately, but, contemptuous of material
projectiles, the spheres made no attempt to dodge, but merely lashed out
upon them with their ravening rays. So close was the range that they
had no time to avoid the radio-directed bombs after discovering that
their beams were useless against the unknown protective covering of
those mirrored shells. There were four practically simultaneous
detonations—silent, but terrific explosions as the pent-up internal
energy of solid pentavalent nitrogen was instantaneously released—and
the four insensately murderous spheres disappeared into jagged fragments
of wreckage, flying wildly away from the centers of explosion. One great
mass of riven and twisted metal was blown directly upon the fifth globe,
and Nadia stared in horrified fascination at the silent crash as the
entire side of the ship crumpled inward like a shell of cardboard under
the awful impact. That vessel was probably out of action, but Stevens
was taking no chances. As soon as he had clamped a pale blue tractor rod
upon the sixth and last of the enemy fleet, he drove a torpedo through
the gaping wall and into the interior of the helpless war-vessel. There
he exploded it, and the awful charge, detonated in that confined space,
literally tore the globular space-ship to bits.</p>
<p>"We'll show these jaspers what kind of trees make shingles!" he gritted
between clenched teeth; and his eyes, hard now as gray iron, fairly
emitted sparks as he launched four torpedoes upon the sole remaining
globe of the squadron of the void. "I've had a lot of curiosity to know
just what kind of unnatural monstrosities can possibly have such
fiendish dispositions as they've got—but beasts, men or devils, they'll
find they've grabbed something this time they can't let go of," and
fierce blasts of energy ripped from the exhausts as he drove his
missiles, at their highest possible acceleration, toward the captive
sphere so savagely struggling at the extremity of his tractor beam.</p>
<p>But that one remaining vessel was to prove no such easy victim as had
its sister ships. Being six to one, and supposedly invincible, the
squadron had been overconfident and had attacked carelessly, with only
its crippling slicing beams instead of its more deadly weapons of total
destruction; and so fierce and hard had been Stevens' counter-attack
that five of its numbers had been destroyed before they realized what
powerful armament was mounted by that apparently crude, helpless,
and innocuous wedge. The sixth, however, was fully warned, and every
resource at the command of its hellish crew was now being directed
against the <i>Forlorn Hope</i>.</p>
<p>Sheets, cones, and gigantic rods of force flashed and crackled. Space
was filled with silent, devastating tongues of flame. The <i>Forlorn
Hope</i> was dragged about erratically as the sphere tried to dodge those
hurtling torpedoes; tried to break away from the hawser of energy
anchoring her so solidly to her opponent. But the linkage held, and
closer and closer Stevens drove the fourfold menace of his frightful
dirigible bombs. Pressor beams beat upon them in vain. Hard driven as
those pushers were, they could find no footing, but were reflected at
many angles by that untouchable mirror and their utmost force scarcely
impeded the progress of the rocket-propelled missiles. Comparatively
small as the projectiles were, however, they soon felt the effects of
the prodigious beams of heat enveloping them, and torpedo after torpedo
exploded harmlessly in space as their mirrors warmed up and volatilized.
But for each bomb that was lost, Stevens launched another, and each one
came closer to its objective than had its predecessor.</p>
<p>Made desperate by the failure of his every beam, the enemy commander
thought to use material projectiles himself—weapons abandoned long
since by his race as antiquated and inefficient, but a few of which were
still carried by the older types of vessels. One such shell was found
and launched—but in the instant of its launching Stevens' foremost bomb
struck its mark and exploded. So close were the other three bombs, that
they also let go at the shock; and the warlike sphere, hemmed in by four
centers of explosions, flew apart—literally pulverized. Its projectile,
so barely discharged, did not explode—it was loaded with material which
could be detonated only by the warhead upon impact or by a radio signal.
It was, however, deflected markedly from its course by the force of the
blast, so that instead of striking the <i>Forlorn Hope</i> in direct central
impact, its head merely touched the apex of the mirror-plated wedge.
That touch was enough. There was another appalling concussion, another
blinding glare, and the entire front quarter of the terrestrial vessel
had gone to join the shattered globes.</p>
<p>Between the point of explosion and the lifeboats there had been many
channels of insulation, many bulkheads, many air-breaks, and compartment
after compartment of accumulator cells. These had borne the brunt of the
explosion, so that the control room was unharmed, and Stevens swung his
communicator rapidly through the damaged portions of the vessels.</p>
<p>"How badly are we hurt, Steve—can we make it to Ganymede?"</p>
<p>Nadia was quietly staring over his shoulder into the plate, studying
with him the pictures of destruction there portrayed as he flashed the
projector from compartment to compartment.</p>
<p>"We're hurt—no fooling—but it might have been a lot worse," he
replied, as he completed the survey. "We've lost about all of our
accumulators, but we can land on our own beam, and landing power is all
we want, I think. You see, we're drifting straight for where Ganymede
will be, and we'd better cut out every bit of power we're using, even
the heaters, until we get there. This lifeboat will hold heat for quite
a while, and I'd rather get pretty cold than meet any more of that gang.
I figured eight hours just before they met us, and we were just about
drifting then. I think it is safe to say seven hours blind."</p>
<p>"But can't they detect us anyway? They may have sent out a call, you
know."</p>
<p>"If we aren't using any power for anything, their electr-omagnetics are
the only things we'll register on, and they're mighty short-range
finders. Even if they should get that close to us, they'll probably
think we're meteoric, since we'll be dead to their other instruments.
Luckily we've got lots of air, so the chemical purifiers can handle it
without power. I'll shut off everything and we'll drift it. Couldn't do
much of anything, anyway—even our shop out there won't hold air. But we
can have light. We've got acetylene emergency lamps, you know, and we
don't need to economize on oxygen."</p>
<p>"Perhaps we'd better run in the dark. Remember what you told me about
their possible visirays, and that you've got only two bombs left."</p>
<p>"All x; that would be better. If I forget it, remind me to blow up those
before we hit the atmosphere of Ganymede, will you?" He opened all the
power switches, and, every source of ethereal vibrations cut off, the
<i>Forlorn Hope</i> drifted slowly on, now appearing forlorn indeed.</p>
<p class="first">
<span class="drop">S</span><span class="up">even</span> hours dragged past: seven age-long hours during which the two sat
tense, expecting they knew not what, talking only at intervals and in
subdued tones. Stevens then snapped on the communicator beam just long
enough to take an observation upon Ganymede. Several such brief glimpses
were taken; then, after a warning word to his companion, he sent out and
exploded the nitrogen bombs. He then threw on the power, and the vessel
leaped toward the satellite under full acceleration. Close to the
atmosphere it slanted downward in a screaming, fifteen-hundred-mile
drive; and soon the mangled wedge dropped down into the little canyon,
which for so long had been "home."</p>
<p>"Well, colonel, home again!" Stevens exulted as he neutralized the
controls. "There's that falls, our power plant, the catapults, 'n'
everything. Now, unless something interrupts us again; we'll run up
our radio tower and give Brandon the long yell."</p>
<p>"How much more have you got to do before you can start sending?"</p>
<p>"Not an awful lot. Everything built—all I've got to do is assemble
it. I should be able to do it easily in a week. Hope nothing else
happens—if I drag you into any more such messes as those we've just
been getting out of by the skin of our teeth, I'll begin to wish that
we had started out at first to drift it back to Tellus in the <i>Hope</i>.
Let's see how much time we've got. We should start shooting one day
after an eclipse, so that we'll have five days to send. You see, we
don't want to point our beam too close to Jupiter or to any of the large
satellites, because the enemy might live there and might intercept it.
We had an eclipse yesterday—so one week from today, at sunrise, I
start shooting."</p>
<p>"But Earth's an evening star now; you can't see it in the morning."</p>
<p>"I'm not going to aim at Tellus. I'm shooting at Brandon, and he's never
there for more than a week or two at a stretch. They're prowling around
out in space somewhere almost all the time."</p>
<p>"Then how can you possibly hope to hit them?"</p>
<p>"It may be quite a job of hunting, but not as bad as you might think.
They probably aren't much, if any, outside the orbit of Mars, and
they usually stay within a couple of million kilometers or so of the
Ecliptic, so we'll start at the sun and shoot our beam in a spiral
to cover that field. We ought to be able to hit them inside of twelve
hours, but if we don't, we'll widen our spiral and keep on trying until
we do hit them."</p>
<p>"Heavens, Steve! Are you planning on telegraphing steadily for days at
a time?"</p>
<p>"Sure, but not by hand, of course—I'll have an automatic sender and
automatic pointers."</p>
<p>Stevens had at his command a very complete machine-shop, he had an ample
supply of power, and all that remained for him to do was to assemble the
parts which he had built during the long journey from Titan to Ganymede.
Therefore, at sunrise of the designated day, he was ready, and, with
Nadia hanging breathless over his shoulder, he closed the switch, a
toothed wheel engaged a delicate interrupter, and a light sounder began
its strident chatter.</p>
<p>"Ganymede point oh four seven ganymede point oh four seven ganymede
point oh four seven..." endlessly the message was poured out into the
ether, carried by a tight beam of ultra-vibrations and driven by forces
sufficient to propel it well beyond the opposite limits of the orbit
of Mars.</p>
<p>"What does it say? I can't read code."</p>
<p>Stevens translated the brief message, but Nadia remained unimpressed.</p>
<p>"But it doesn't say anything!" she protested. "It isn't addressed to
anybody, it isn't signed—it doesn't tell anybody anything about
anything."</p>
<p>"It's all there, ace. You see, since the beam is moving sidewise very
rapidly at that range and we're shooting at a small target, the message
has to be very short or they won't get it all while the beam's on
'em—it isn't as though we were broadcasting. It doesn't need any
address, because nobody but the <i>Sirius</i> can receive it—except possibly
the Jovians. They'll know who's sending it without any signature. It
tells them that Ganymede wants to receive a message on the ultra-band
centering on forty-seven thousandths. Isn't that enough?"</p>
<p>"Maybe. But suppose some of them live right here on Ganymede—you'll
be shooting right through the ground all night—or suppose that even if
they don't live here, that they can find our beam some way? Or suppose
that Brandon hasn't got his machine built yet, or suppose that it isn't
turned on when our beam passes them, or suppose they're asleep then?
A lot of things might happen."</p>
<p>"Not so many, ace—your first objection is the only one that hasn't got
more holes in it than a sieve, so I'll take it first. Since our beam is
only a meter in diameter here and doesn't spread much in the first few
million kilometers, the chance of direct reception by the enemy, even
if they do live here on Ganymede, is infinitesimally small. But I don't
believe that they live here—at least, they certainly didn't land on
this satellite. As you suggest, however, it is conceivable that they may
have detector screens delicate enough to locate our beam at a distance;
but since in all probability that means a distance of hundreds of
thousands of kilometers, I think it highly improbable. We've got to take
the same risk anyway, no matter what we do, whenever we start to use any
kind of driving power, so there's no use worrying about it. As for your
last two objections, I know Brandon and I know Westfall. Brandon will
have receivers built that will take in any wave possible of propagation,
and Westfall, the cautious old egg, will have them running twenty-four
hours a day, with automatic recorders, finders, and everything else that
Brandon can invent—and believe me, sweetheart, that's a lot of stuff!"</p>
<p>"It's wonderful, the way you three men are," replied Nadia thoughtfully,
reading between the lines of Stevens' utterance. "They knew that you
were on the <i>Arcturus</i>, of course—and they knew that if you were alive
you'd manage in some way to get in touch with them. And you, away out
here after all this time, are superbly confident that they are expecting
a call from you. That, I think, is one of the finest things I ever heard
of."</p>
<p>"They're two of the world's best—absolutely." Nadia looked at him,
surprised, for he had not seen anything complimentary to himself in her
remark. "Wait until you meet them. They're men, Nadia—real men. And
speaking of meeting them—please try to keep on loving me after you meet
Norm Brandon, will you?"</p>
<p>"Don't be a simp!" her brown eyes met his steadily. "You didn't mean
that—you didn't even say it, did you?"</p>
<p>"Back it comes, sweetheart! But knowing myself and knowing those
two...."</p>
<p>"Stop it! If Norman Brandon or Quincy Westfall had been here instead
of you, or both of them together, we'd have been here from now on—we
wouldn't even have gotten away from the Jovians!"</p>
<p class="first">
<span class="drop">"N</span><span class="up">ow</span> it's your turn to back water, guy!"</p>
<p>"Well, maybe, a little—if both of them were here, they ought to equal
you in some things. Brandon says himself that he and Westfall together
make one scientist—Dad says he says so."</p>
<p>"You don't want to believe everything you hear. Neither of them will
admit that he knows anything or can do anything—that's the way they
are."</p>
<p>"Dad has told me a lot about them—how they've always been together
ever since their undergraduate days. How they studied together all over
the world, even after they'd been given all the degrees loose. How
they even went to the other planets to study—to Mars, where they had
to live in space-suits all the time, and to Venus, where they had to
take ultra-violet treatments every day to keep alive. How they learned
everything that everybody else knew and then went out into space to find
out things that nobody else ever dreamed of. How you came to join them,
and what you three have done since. They're fine, of course—but they
aren't <i>you</i>," she concluded passionately.</p>
<p>"No, thank Heaven! I know you love me, Nadia, just as I love you—you
know I never doubted it. But you'll like them, really. They're a
wonderful team. Brandon's a big brute, you know—fully five centimeters
taller than I am, and he weighs close to a hundred kilograms—and no
lard, either. He's wild, impetuous, always jumping at conclusions and
working out theories that seem absolutely ridiculous, but they're
usually sound, even though impractical. Westfall's the practical
member—he makes Norm pipe down, pins him down to facts, and makes it
possible to put his hunches and wild flashes of genius into workable
form. Quince is a...."</p>
<p>"Now <i>you</i> pipe down! I've heard you rave <i>so</i> much about those two—I'd
lots rather rave about you, and with more reason. I wish that sounder
would start sounding."</p>
<p>"Our first message hasn't gone half way yet. It takes about forty
minutes for the impulse to get to where I think they are, so that even
if they got the first one and answered it instantly, it would be eighty
minutes before we'd get it. I sort of expect an answer late tonight, but
I won't be disappointed if it takes a week to locate them."</p>
<p>"I will!" declared the girl, and indeed, very little work was done that
day by either of the castaways.</p>
<p>Slowly the day wore on, and the receiving sounder remained silent.
Supper was eaten as the sun dropped low and disappeared, but they felt
no desire to sleep. Instead, they went out in front of the steel wall,
where Stevens built a small campfire. Leaning back against the wall of
their vessel, they fell into companionable silence, which was suddenly
broken by Stevens.</p>
<p>"Nadia, I just had a thought. I'll bet four dollars I've wasted a lot of
time. They'll certainly have automatic relays on Tellus, to save me the
trouble of hunting for them, but like an idiot I never thought of it
until just this minute, in spite of the speech I made you about them.
I'm going to change those directors right now."</p>
<p>"That's quite a job, isn't it?"</p>
<p>"No, only a few minutes."</p>
<p>"Do it in the morning; you've done enough for one day—maybe you've hit
them already, any way."</p>
<p>They again became silent, watching Jupiter, an enormous moon some seven
degrees in apparent diameter.</p>
<p>"Steve, I simply can't get used to such a prodigious moon! Look at the
stripes, and look at that perfectly incredible...."</p>
<p>A gong sounded and they both jumped to their feet and raced madly into
the <i>Hope</i>. The ultra-receiver had come to life and the sounder was
chattering insanely—someone was sending with terrific speed, but with
perfect definition and spacing.</p>
<p>"That's Brandon's fist—I'd know his style anywhere," Stevens shouted,
as he seized notebook and pencil.</p>
<p>"Tell me what it says, quick, Steve!" Nadia implored.</p>
<p>"Can't talk—read it!" Stevens snapped. His hand was flying over the
paper, racing to keep up with the screaming sounder.</p>
<p>"...ymede all x stevens ganymede all x stevens ganymede all x placing

forty north going tellus first send full data spreading beam to
cover circle fifteen forty quince suggests possibility this message
intercepted and translated personally I think such translation
impossible and that he is wilder than a hawk but just in case they
should be supernaturally intelligent...."</p>
<p>Stevens stopped abruptly and stared at the vociferous sounder.</p>
<p>"Don't stop to listen—keep on writing!" commanded Nadia.</p>
<p>"Can't," replied the puzzled mathematician. "It doesn't make sense. It
sounds intelligent—it's made up of real symbols of some kind or other,
but they don't mean a thing to me."</p>
<p>"Oh, I see—he's sending mush on purpose. Read the last phrase!"</p>
<p>"Oh, sure—'mush' is right," and with no perceptible break the signals
again became intelligible.</p>
<p>"... if they can translate that they are better scholars than we are
signing off until hear from you brandon."</p>
<p class="first">
<span class="drop">T</span><span class="up">he</span> sounder died abruptly into silence and Nadia sobbed convulsively
as she threw herself into Stevens' arms. The long strain over, the
terrible uncertainty at last dispelled, they were both incoherent for
a minute—Nadia glorifying the exploits of her lover, Stevens crediting
the girl herself and his two fellow-scientists with whatever success had
been achieved. A measure of self-control regained, Stevens cut off his
automatic sender, changed the adjustments of his directors and cut in
his manually operated sending key.</p>
<p>"What waves are you using, anyway?" asked Nadia, curiously. "They must
be even more penetrating than Roeser's Rays, to have such a range, and
Roeser's Rays go right through a planet without even slowing up."</p>
<p>"They're of the same order as Roeser's—that is, they're sub-electronic
waves of the fourth order—but they're very much shorter, and hence more
penetrating. In fact, they're the shortest waves yet known, so short
that Roeser never even suspected their existence."</p>
<p>"Suppose there's a Jovian space-ship out there somewhere that intercepts
our beams. Couldn't they locate us from it?"</p>
<p>"Maybe, and maybe not—we'll just have to take a chance on that. That
goes right back to what we were talking about this morning. They might
be anywhere, so the chance of hitting one is very small. It isn't like
hitting the <i>Sirius</i>, because we knew within pretty narrow limits where
to look for her, and even at that we had to hunt for her for half a day
before we hit her. We're probably safe, but even if they should have
located us, we'll probably be able to hide somewhere until the <i>Sirius</i>
gets here. Well, the quicker I get busy sending the dope, the sooner
they can get started."</p>
<p>"Tell them to be sure and bring me all my clothes they can find,
a gallon of perfume, a barrel of powder, and a carload of Delray's
Fantasie chocolates—I've been a savage so long that I want to wallow
in luxury for a while."</p>
<p>"I'll do that—and I want some real cigarettes!"</p>
<p>Stevens first sent a terse, but complete account of everything that had
happened to the <i>Arcturus</i>, and a brief summary of what he and Nadia
had done since the cutting up of the IPV. The narrative finished, he
launched into a prolonged and detailed scientific discussion of the
enemy and their offensive and defensive weapons. He dwelt precisely and
at length upon the functioning of everything he had seen. Though during
the long months of their isolation he had been too busy to do any actual
work upon the weapons of the supposed Jovians, yet his keen mind had
evolved many mathematical and physical deductions, hypotheses, and
theories, and these he sent out to the <i>Sirius</i>, concluding:</p>
<p>"There's all the dope I can give you. Figure it out, and don't come at
all until you can come loaded for bear; they're bad medicine. Call us
occasionally, to keep us informed as to when to expect you, but don't
call too often. We don't want them locating you, and if they should
locate us through your ray or ours, it would be just too bad. So-long.
Stevens and Newton."</p>
<p>Nadia had insisted upon staying up and had been brewing pot after pot
of her substitutes for coffee while he sat at the key; and it was
almost daylight when he finally shut off the power and arose, his
right arm practically paralyzed from the unaccustomed strain of hours
of telegraphing.</p>
<p>"Well, sweetheart, that's that!" he exclaimed in relief. "Brandon and
Westfall are on the job. Nothing to do now but wait, and study up on our
own account on those Jovians' rays. This has been one long day for us,
though, little ace, and I suggest that we sleep for about a week!"</p>
