The Greatest Works of E. E. Smith. E. E. Smith
in the stratosphere, speeding eastward, the immense mass of the Boise slowed abruptly, although no projector had slackened its effort. Cleveland, eyes upon interferometer grating and spectrophotometer charts, fingers flying over calculator keys, grinned as he turned toward Rodebush.
"Just as you thought, Skipper; an ultra-band pusher. C4V63L29. Shall I give him a little pull?"
"Not yet; let's feel him out a little before we force a close-up. We've got plenty of mass. See what he does when I put full push on the projectors."
As the full power of the Tellurian vessel was applied the Nevian was forced backward, away from the threatened city, against the full drive of her every projector. Soon, however, the advance was again checked, and both scientists read the reason upon their plates. The enemy had put down reenforcing rods of tremendous power. Three compression members spread out fanwise behind her, bracing her against a low mountainside, while one huge tractor beam was thrust directly downward, holding in an unbreakable grip a cylinder of earth extending deep down into bedrock.
"Two can play at that game!" and Rodebush drove down similar beams, and forward-reaching tractors as well. "Strap yourselves in solid, everybody!" he sounded in general warning. "Something is going to give way somewhere soon, and when it does we'll get a jolt!"
And the promised jolt did indeed come soon. Prodigiously massive and powerful as the Nevian was, the Boise was even more massive and more powerful; and as the already enormous energy feeding the tractors, pushers, and projectors was raised to its inconceivable maximum, the vessel of the enemy was hurled upward, backward; and that of Earth shot ahead with a bounding leap that threatened to strain even her mighty members. The Nevian anchor rods had not broken; they had simply pulled up the vast cylinders of solid rock that had formed their anchorages.
"Grab him now!" Rodebush yelled, and even while an avalanche of falling rock was burying the countryside Cleveland snapped a tractor ray upon the flying fish and pulled tentatively.
Nor did the Nevian now seem averse to coming to grips. The two warring super-dreadnoughts darted toward each other, and from the invader there flooded out the dread crimson opacity which had theretofore meant the doom of all things Solarian. Flooded out and engulfed the immense globe of humanity's hope in its spreading cloud of redly impenetrable murk. But not for long. Triplanetary's super-ship boasted no ordinary Terrestrial defense, but was sheathed in screen after screen of ultra-vibrations: imponderable walls, it is true, but barriers impenetrable to any unfriendly wave. To the outer screen the red veil of the Nevians clung tenaciously, licking greedily at every square inch of the shielding sphere of force, but unable to find an opening through which to feed upon the steel of the Boise's armor.
"Get back—'way back! Go back and help Pittsburgh!" Rodebush drove an ultra communicator beam through the murk to the instruments of the Terrestrial admiral; for the surviving warships of the fleet—its most powerful units—were hurling themselves forward, to plunge into that red destruction. "None of you will last a second in this red field. And watch out for a violet field pretty soon—it'll be worse than this. We can handle them alone, I think; but if we can't, there's nothing in the System that can help us!"
And now the hitherto passive screen of the super-ship became active. At first invisible, it began to glow in fierce violet light, and as the glow brightened to unbearable intensity the entire spherical shield began to increase in size. Driven outward from the super-ship as a center, its advancing surface of seething energy consumed the crimson murk as a billow of blast-furnace heat consumes the cloud of snowflakes in the air above its cupola. Nor was the red death-mist all that was consumed. Between that ravening surface and the armor skin of the Boise there was nothing. No debris, no atmosphere, no vapor, no single atom of material substance—the first time in Terrestrial experience that an absolute vacuum had ever been attained!
Stubbornly contesting every foot of way lost, the Nevian fog retreated before the violet sphere of nothingness. Back and back it fell, disappearing altogether from all space as the violet tide engulfed the enemy vessel; but the flying fish did not disappear. Her triple screens flashed into furiously incandescent splendor and she entered unscathed that vacuous sphere, which collapsed instantly into an enormously elongated ellipsoid, at each focus a madly warring ship of space.
Then in that tube of vacuum was waged a spectacular duel of ultra-weapons—weapons impotent in air, but deadly in empty space. Beams, rays, and rods of Titanic power smote crackingly against ultra-screens equally capable. Time after time each contestant ran the gamut of the spectrum with his every available ultra-force, only to find all channels closed. For minutes the terrible struggle went on, then:
"Cooper, Adlington, Spencer, Dutton!" Rodebush called into his transmitter. "Ready? Can't touch him on the ultra, so I'm going onto the macro-bands. Give him everything you have as soon as I collapse the violet. Go!"
At the word the violet barrier went down, and with a crash as of a disrupting Universe the atmosphere rushed into the void. And through the hurricane there shot out the deadliest material weapons of Triplanetary. Torpedoes—non-ferrous, ultra-screened, beam-dirigible torpedoes charged with the most effective forms of material destruction known to man. Cooper hurled his canisters of penetrating gas, Adlington his allotropic-iron atomic bombs, Spencer his indestructible armor-piercing projectiles, and Dutton his shatterable flasks of the quintessence of corrosion—a sticky, tacky liquid of such dire potency that only one rare Solarian element could contain it. Ten, twenty, fifty, a hundred were thrown as fast as the automatic machinery could launch them; and the Nevians found them adversaries not to be despised. Size for size, their screens were quite as capable as those of the Boise. The Nevians' destructive rays glanced harmlessly from their shields, and the Nevians' elaborate screens, neutralized at impact by those of the torpedoes, were impotent to impede their progress. Each projectile must needs be caught and crushed individually by beams of the most prodigious power; and while one was being annihilated dozens more were rushing to the attack. Then while the twisting, dodging invader was busiest with the tiny but relentless destroyers, Rodebush launched his heaviest weapon.
The macro-beams! Prodigious streamers of bluish-green flame which tore savagely through course after course of Nevian screen! Malevolent fangs, driven with such power and velocity that they were biting into the very walls of the enemy vessel before the amphibians knew that their defensive shells of force had been punctured! And the emergency screens of the invaders were equally futile. Course after course was sent out, only to flare viciously through the spectrum and to go black.
Outfought at every turn, the now frantically dodging Nevian leaped away in headlong flight, only to be brought to a staggering, crashing halt as Cleveland nailed her with a tractor beam. But the Tellurians were to learn that the Nevians held in reserve a means of retreat. The tractor snapped—sheared off squarely by a sizzling plane of force—and the fish-shaped cruiser faded from Cleveland's sight, just as the Boise had disappeared from the communicator plates of Radio Center, back in the Hill, when she was launched. But though the plates in the control room could not hold the Nevian, she did not vanish beyond the ken of Randolph, now Communications Officer in the super-ship. For, warned and humiliated by his losing one speeding vessel from his plates in Radio Center, he was now ready for any emergency. Therefore as the Nevian fled Randolph's spy-ray held her, automatically behind it as there was the full output of twelve special banks of iron-driven power tubes; and thus it was that the vengeful Earthmen flashed immediately along the Nevians' line of flight. Inertialess now, pausing briefly from time to time to enable the crew to accustom themselves to the new sensations, Triplanetary's super-ship pursued the invader; hurtling through the void with a velocity unthinkable.
"He was easier to take than I thought he would be," Cleveland grunted, staring into the plate.
"I thought he had more stuff, too," Rodebush assented, "but I guess Costigan got almost everything they had. If so, with all our own stuff and most of theirs besides, we should be able to take them. Conway's data indicated that they have only partial neutralization of inertia—if it's one hundred percent we'll never catch them—but it isn't—there they are!"
"And this time I'm going to hold her or burn out all our generators trying," Cleveland declared, grimly. "Are you fellows down there able to handle
