WORM, SUBMARINE, AND FREEDOM
Since both Costigan and Bradley had often watched their captors at work
during the long voyage from the Solar System to Nevia, they were quite
familiar with the machine tools of the amphibians. Their stolen
lifeboat, being an emergency craft, of course carried full repair
equipment; and to such good purpose did the two officers labor that even
before their air-tanks were fully charged, all the damage had been
repaired.
The lifeboat lay motionless upon the mirror-smooth surface of the ocean.
Captain Bradley had opened the upper port and the three stood in the
opening, gazing in silence toward the incredibly distant horizon, while
powerful pumps were forcing the last possible ounces of air into the
storage cylinders. Mile upon strangely flat mile stretched that
waveless, unbroken expanse of water, merging finally into the violent
redness of the Nevian sky. The sun was setting; a vast ball of purple
flame dropping rapidly toward the horizon. Darkness came suddenly as
that seething ball disappeared, and the air became bitterly cold, in
sharp contrast to the pleasant warmth of a moment before. And as
suddenly clouds appeared in blackly banked masses and a cold, driving
rain began to beat down.
"Br-r-r, it's cold! Let's go in--Oh! _Shut the door!_" Clio shrieked,
and leaped wildly down into the compartment below, out of Costigan's
way, for he and Bradley had also seen slithering toward them the
frightful arm of the Thing.
Almost before the girl had spoken Costigan had leaped to the controls,
and not an instant too soon; for the tip of that horrible tentacle
flashed into the rapidly narrowing crack just before the door clanged
shut. As the powerful toggles forced the heavy wedges into engagement
and drove the massive disk home, that grisly tip fell severed to the
floor of the compartment and lay there, twitching and writhing with a
loathesome and unearthly vigor. Two feet long the piece was, and larger
than a strong man's leg. It was armed with spiked and jointed metallic
scales, and instead of sucking disks it was equipped with a series of
_mouths_--mouths filled with sharp metallic teeth which gnashed and
ground together furiously, even though sundered from the horrible
organism which they were designed to feed.
The little submarine shuddered in every plate and member as monstrous
coils encircled her and tightened inexorably in terrific, rippling
surges eloquent of mastodonic power; and a strident vibration smote
sickeningly upon Terrestrial ear-drums as the metal spikes of the
monstrosity crunched and ground upon the outer plating of their small
vessel. Costigan stood unmoved at the plate, watching intently; hands
ready upon the controls. Due to the artificial gravity of the lifeboat
it seemed perfectly stationary to its occupants. Only the weird
gyrations of the pictures upon the lookout screens showed that the craft
was being shaken and thrown about like a rat in the jaws of a terrier;
only the gauges revealed that they were almost a mile below the surface
of the ocean already, and were still going downward at an appalling
rate. Finally Clio could stand no more.
"Aren't you going to do something, Conway?" she cried.
"Not unless I have to," he replied, composedly. "I don't believe that
he can really hurt us, and if I use force of any kind I'm afraid that it
will kick up enough disturbance to bring Nerado down on us like a hawk
onto a chicken. However, if he takes us much deeper I'll have to go to
work on him. We're getting down pretty close to our limit, and the
bottom's a long ways down yet."
Deeper and deeper the lifeboat was dragged by its dreadful opponent,
whose spiked teeth still tore savagely at the tough outer plating of the
craft, until Costigan reluctantly threw in his power switches. Against
the full propellant thrust the monster could draw them no lower, but
neither could the lifeboat make any headway toward the surface. The
pilot then turned on his beams, but found that they were ineffective. So
closely was the creature wrapped around the submarine that his weapons
could not be brought to bear upon it.
"What can it possibly be, anyway, and what can we do about it?" Clio
asked.
"I thought at first it was something like a devilfish, or possibly an
overgrown starfish, but it isn't," Costigan made answer. "It must be a
kind of flat worm. That doesn't sound reasonable--the thing must be all
of a hundred meters long--but there it is. The only thing left to do
that I can think of is to try to boil him alive."
He closed other circuits, diffusing a terrific beam of pure heat, and
the water all about them burst into furious clouds of steam. The boat
leaped upward as the metallic fins of the gigantic worm fanned vapor
instead of water, but the creature neither released its hold nor ceased
its relentlessly grinding attack. Minute after minute went by, but
finally the worm dropped limply away--cooked through and through;
vanquished only by death.
"Now we've put our foot in it, clear to the neck!" Costigan exclaimed,
as he shot the lifeboat upward at its maximum power. "Look at that! I
knew that Nerado could trace us, but I didn't have any idea that _they_
could!"
Staring with Costigan into the plate, Bradley and the girl saw, not the
Nevian sky-rover they had expected, but a fast submarine cruiser, manned
by the frightful fishes of the greater deeps. It was coming directly
toward the lifeboat, and even as Costigan hurled the little vessel off
at an angle and then sped upward into the air, one of the deadly
offensive rods, tipped with its glowing ball of pure destruction,
flashed through the spot where they would have been had they held their
former course.
But powerful as were the propellant forces of the lifeboat and fiercely
though Costigan applied them, the denizens of the deep clamped a tractor
beam upon the flying vessel before it had gained a mile of altitude.
Costigan aligned his every driving projector as his vessel came to an
abrupt halt in the invisible grip of the beam, then experimented with
various dials.
"There ought to be some way of cutting that beam," he pondered audibly,
"but I don't know enough about their system to do it, and I'm afraid to
monkey around with things too much, because I might accidentally release
the screens we've already got out, and they're stopping altogether too
much stuff for us to do without them right now."
He frowned as he studied the flaring defensive screens, now radiating an
incandescent violet under the concentration of forces being hurled
against them by the warlike fishes, then stiffened suddenly.
"I thought so--they _can_ shoot 'em!" he exclaimed, throwing the
lifeboat into a furious corkscrew turn, and the very air blazed into
flaming splendor as a dazzlingly scintillating ball of energy sped past
them and high into the air beyond.
Then for minutes a spectacular battle raged. The twisting, turning,
leaping airship, small as she was and agile, kept on eluding the
explosive projectiles of the fishes, and her screens neutralized and
re-radiated the full power of the attacking beams. More--since Costigan
did not need to think of sparing his iron, the ocean around the great
submarine began furiously to boil under the full-driven offensive beams
of the tiny Nevian ship. But escape Costigan could not. He could not cut
that tractor beam and the utmost power of his drivers could not wrest
the lifeboat from its tenacious clutch. And slowly but inexorably the
ship of space was being drawn downward toward the ship of ocean's
depths. Downward, in spite of the utmost possible effort of every
projector and generator; and Clio and Bradley, sick at heart, looked
once at each other. Then they looked at Costigan, who, jaw hard set and
eyes unflinchingly upon his plate, was concentrating his attack upon one
turret of the green monster as they settled lower and lower.
"If this is ... if our number is going up, Conway," Clio began,
unsteadily.
"Not yet, it isn't!" he snapped. "Keep a stiff upper lip, girl. We're
still breathing air, and the battle's not over yet!"
Nor was it; but it was not Costigan's efforts, mighty though they were,
that ended the attack of the fishes of the greater deeps. The tractor
beams snapped without warning, and so prodigious were the forces being
exerted by the lifeboat that as it hurled itself away the three
passengers were thrown violently to the floor, in spite of the powerful
gravity controls. Scrambling up on hands and knees, bracing himself as
best he could against the terrific forces, Costigan managed finally to
force a hand up to his panel. He was barely in time; for even as he cut
the driving power to its normal value the outer shell of the lifeboat
was blazing at white heat from the friction of the atmosphere through
which it had been tearing with such an insane acceleration!
"Oh, I see--Nerado to the rescue," Costigan commented, after a glance
into the plate. "I hope that those fish blow him clear out of the
Galaxy!"
"Why?" demanded Clio. "I should think that you'd...."
"Think again," he advised her. "The worse Nerado gets licked the better
for us. I don't really expect that, but if they can keep him busy long
enough, we can get far enough away so that he won't bother about us any
more."
As the lifeboat tore upward through the air at the highest permissible
atmospheric velocity Bradley and Clio peered over Costigan's shoulders
into the plate, watching in fascinated interest the scene which was
being kept in focus upon it. The Nevian ship of space was plunging
downward in a long, slanting dive, her terrific beams of force screaming
out ahead of her. The beams of the little lifeboat had boiled the waters
of the ocean; those of the parent craft seemed literally to blast them
out of existence. All about the green submarine there had been volumes
of furiously-boiling water and dense clouds of vapor; now water and fog
alike disappeared, converted into transparent super-heated steam by the
blasts of Nevian energy. Through that tenuous gas the enormous mass of
the submarine fell like a plummet, her defensive screens flaming an
almost invisible violet, her every offensive weapon vomiting forth solid
and vibratory destruction toward the Nevian cruiser so high in the
angry, scarlet heavens.
For miles the submarine dropped, until the frightful pressure of the
depth drove water into Nerado's beam faster than his forces could
volatilize it. Then in that seething funnel there was waged a starkly
fantastic conflict. At its wildly turbulent bottom lay the submarine,
now apparently trying to escape, but held fast by the tractors of the
space-ship; at its top, smothered almost to the point of invisibility by
billowing masses of steam, hung poised the Nevian cruiser.
As the atmosphere had grown thinner and thinner with increasing
altitude Costigan had regulated his velocity accordingly, keeping the
outer shell of the vessel at the highest temperature consistent with
safety. Now beyond measurable atmospheric pressure, the shell cooled
rapidly and he applied full touring acceleration. At an appalling and
constantly increasing speed the miniature space-ship shot away from the
strange, red planet; and smaller and smaller upon the plate became its
picture. The great vessel of the void had long since plunged beneath the
surface of the sea, to come more closely to grips with the vessel of the
fishes; for a long time nothing of the battle had been visible save
immense clouds of steam, blanketing hundreds of square miles of the
ocean's surface. But just before the picture became too small to reveal
details a few tiny dark spots appeared above the banks of cloud, now
brilliantly illuminated by the rays of the rising sun--dots which might
have been fragments of either vessel, blown bodily from the depths of
the ocean and, riven asunder, hurled high into the air by the incredible
forces at the command of the other.
Nevia a tiny moon and the fierce blue sun rapidly growing smaller in the
distance, Costigan swung his visiray beam into the line of travel and
turned to his companions.
"Well, we're off," he said, scowling. "I hope it was Nerado that got
blown up back there, but I'm afraid it wasn't. He whipped two of those
submarines that we know of, and probably half their fleet besides.
There's no particular reason why that one should be able to take him, so
it's my idea that we should get ready for great gobs of trouble. They'll
chase us, of course; and I'm afraid that with their power, they'll catch
us."
"But what can we do, Conway?" asked Clio.
"Several things," he grinned. "I managed to get quite a lot of dope on
that paralyzing ray and some of their other stuff, and we can install
the necessary equipment in our suits easily enough."
They removed their armor, and Costigan explained in detail the changes
which must be made in the Triplanetary field generators. All three set
vigorously to work--the two officers deftly and surely; Clio uncertainly
and with many questions, but with undaunted spirit. Finally, having done
everything they could do to strengthen their position, they settled down
to the watchful routine of the flight, with every possible instrument
set to detect any sign of the pursuit they so feared.
