Part 23 (2/2)

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 airs.h.i.+p, 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 s.h.i.+p. 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 s.h.i.+p of s.p.a.ce was being drawn downward toward the s.h.i.+p 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 s.h.i.+p 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-s.h.i.+p; 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-s.h.i.+p 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-s.h.i.+ps 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; flas.h.i.+ng 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.
