Costigan watched his plate closely; and, when the maneuvering of the great vessel brought his exit port as far away as possible from the Third City and the warring tanks, he shot the little cruiser out and away. Straight out into the ocean it sped, through the murky red veil, and darted upward toward the surface. The three wanderers sat tense, hardly daring to breathe, staring into the plates-Clio and Bradley pushing at mental levers and stepping down hard upon mental brakes in unconscious efforts to help Costigan dodge the beams and rods of death flashing so appallingly close upon all sides. Out of the water and into the air the darting, dodging lifeboat flashed in safety; but in the air, supposedly free from menace, came disaster. There was a crunching, grating shock and the vessel was thrown into a dizzy spiral, from which Costigan finally leveled it into headlong flight away from the scene of battle. Watching the pyrometers which recorded the temperature of the outer sh.e.l.l, he drove the lifeboat ahead at the highest safe atmospheric speed while Bradley went to inspect the damage.
"Pretty bad, but better than I thought," the captain reported. "Outer and inner plates broken away on a seam. We wouldn"t hold cotton waste, let alone air. Any tools aboard?"
"Some-and what we haven"t got we"ll make," Costigan declared. "We"ll put a lot of distance behind us, then we"ll fix her up and get away from here."
"What are those fish, anyway, Conway?" Clio asked, as the lifeboat tore along. "The Nevians are bad enough, Heaven knows, but the very idea of intelligent and educated fish is enough to drive one mad!"
"You know Nerado mentioned several times the "semicivilized fishes of the greater deeps"?" he reminded her. "I gather that there are at least three intelligent races here. We know two-the Nevians, who are amphibians, and the fishes of the greater deeps. The fishes of the lesser deeps are also intelligent. As I get it, the Nevian cities were originally built in very shallow water, or perhaps were upon islands. The development of machinery and tools gave them a big edge on the fish; and those living in the shallow seas, nearest the Islands, gradually became tributary nations, if not actually slaves. Those fish not only serve as food, but work in the mines, hatcheries, and plantations, and do all kinds of work for the Nevians. Those so-called "lesser deeps" were conquered first, of course, and all their races of fish are docile enough now. But the deep-sea breeds, who live in water so deep that the Nevians can hardly stand the pressure down there, were more intelligent to start with, and more stubborn besides. But the most valuable metals here are deep down-this planet is very light for its size, you know-so the Nevians kept at it until they conquered some of the deep-sea fish, too, and put "em to work. But those high-pressure boys were n.o.body"s fools. They realized that as time went on the amphibians would get further and further ahead of them in development, so they let themselves be conquered, learned how to use the Nevians" tools and everything else they could get hold of, developed a lot of new stuff of their own, and now they"re out to wipe the amphibians off the map completely, before they get too far ahead of them to handle."
"And the Nevians are afraid of them, and want to kill them all, as fast as they possibly can," guessed Clio.
"That would be the logical thing, of course," commented Bradley. "Got pretty nearly enough distance now, Costigan?"
"There isn"t enough distance on the planet to suit me," Costigan replied. "We"ll need all we can get. A full diameter away from that crew of amphibians is too close for comfort-their detectors are keen."
"Then they can detect us?" Clio asked. "Oh, I wish they hadn"t hit us-we"d have been away from here long ago."
"So do I," Costigan agreed, feelingly. "But they did-no use squawking. We can rivet and weld those seams, and things could be a lot worse-we are still breathing air!"
In silence the lifeboat flashed onward, and half of Nevia"s mighty globe was traversed before it was brought to a halt. Then in furious haste the two officers set to work, again to make their small craft sound and s.p.a.ceworthy.
CHAPTER 12
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 ma.s.ses 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 ma.s.sive 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 alt.i.tude. 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 s.p.a.ce 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 pa.s.sengers 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 sh.e.l.l 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 s.p.a.ce 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 ma.s.s 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 s.p.a.ce-ship; at its top, smothered almost to the point of invisibility by billowing ma.s.ses of steam, hung poised the Nevian cruiser.
As the atmosphere had grown thinner and thinner with increasing alt.i.tude Costigan had regulated his velocity accordingly, keeping the outer sh.e.l.l of the vessel at the highest temperature consistent with safety. Now beyond measurable atmospheric pressure, the sh.e.l.l cooled rapidly and he applied full touring acceleration. At an appalling and constantly increasing speed the miniature s.p.a.ce-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.
CHAPTER 13
THE HILL
The heavy cruiser Chicago hung motionless in s.p.a.ce, thousands of miles distant from the warring fleets of s.p.a.ce-ships so viciously attacking and so stubbornly defending Roger"s planetoid. In the captain"s sanctum Lyman Cleveland crouched tensely above his ultracameras, his sensitive fingers touching lightly their micrometric dials. His body was rigid, his face was set and drawn. Only his eyes moved; flashing back and forth between his instruments and the smoothly-running strands of spring-steel wire upon which were being recorded the frightful scenes of carnage and destruction.
Silent and bitterly absorbed, though surrounded by staring officers whose fervent, almost unconscious cursing was prayerful in its intensity, the visiray expert kept his ultra-instruments upon that awful struggle to its dire conclusion. Flawlessly those instruments noted every detail of the destruction of Roger"s fleet, of the transformation of the armada of Triplanetary into an unknown fluid, and finally of the dissolution of the gigantic planetoid itself. Then furiously Cleveland drove his beam against the crimsonly opaque obscurity into which the peculiar, viscous stream of substance was disappearing. Time after time he applied his every watt of power, with no result. A vast volume of s.p.a.ce, roughly ellipsoidal in shape, was closed to him by forces entirely beyond his experience or comprehension. But suddenly, while his rays were still trying to pierce that impenetrable murk, it disappeared instantly and without warning: the illimitable infinity of s.p.a.ce once more lay revealed upon his plates and his beams flashed unimpeded through the void.
"Back to Tellus, sir?" The Chicago"s captain broke the strained silence.
