Part 4

But now the great fleet, diving sharply amid that deadly uprush of globes, was within a few thousand feet of the sea's floor, was slanting down through the white radiance toward the city below, which Stevens saw for the first time. A moment, as the fleet seemed to pause above the city, he saw it all plain--the multitudes of ranked great globular structures, stretching away as far as the eye could see, the dark, slug-like beings that hastened through their streets and squares, the vast pit at the city's center from which arose the mighty, half-glimpsed current of waters, and the towering spire near that pit's edge, the tiny bulbular room at its top a point of green radiance, around which were grouped scores of the vast, thousand-foot striding-machines. Then that one moment of pause was over and the whole great fleet was swooping down upon the city below, releasing a shower of great torpedoes and bombs as it did so.

The next moment there came a hundred flashes of fire beneath them as the torpedoes and depth-charges struck, and then it seemed as though in a score of places beneath them the city was crumbling, disintegrating, beneath the force of the great explosions. The submarine was rocking and swaying perilously from the effect of those explosions, only the super-resistant hulls of the new-type craft enabling them to endure the shock, but even while Stevens heard the men near him shouting hoarsely he was aware that the massed boats were diving again, and again the thunderous detonations below came dully to their ears through the waters about them.

But now he heard a sudden cry of alarm, taken up and repeated by all in the control room. From far away, all around the great city, there were hastening toward the attacking submarines scores of the giant striding-machines, their vast steps whirling them across the city with inconceivable swiftness, the great arm of each outstretched toward the submarines. An order was barked, and the craft's propellers spun swiftly as it headed upward to avoid those reaching, menacing arms, while the whole great fleet headed up also with the same purpose. The next moment, however, a spark of more brilliant white light broke into being in the city below them--a great, erect cylinder, they saw, that was suddenly shining with a dazzling radiance that darkened the white luminosity of the waters about it. And as it broke into being the submarine below seemed suddenly to waver, to halt, and then to be pulled slowly, steadily downward by great unseen hands, toward that shining cylinder.

Stevens heard the motors throbbing in his own craft, its spinning propellers only serving to hold it in the same position, and heard a shout from Evans.

"That cylinder!" he cried. "It's a great magnet of some kind--it's pulling our ships downward!"

For now by dozens, by scores, by hundreds, the fleet's massed ships were being pulled downward, their screws thrashing the waters in vain, pulled down toward that mighty, dazzling beacon of light. The next moment the great striding-machines had reached them, were grasping them, crushing them, whirling them about like toys and hurling them far away to break and smash upon the globes below, spilling forth men and air-bubbles and great clouds of oil. Ever downward, downward, the mighty magnet of light pulled the helpless craft, while Stevens' own craft, highest of them all, could only resist that terrific pull by all the power of its humming motors. And among the helpless craft below he could see the great machines of the slug-people stalking about in terrific destruction, crushing and smashing the defenseless boats as they sought vainly to escape while Stevens' own craft sought frenziedly to win out of the remorseless grip that held it.

But now, below, the doomed submarines seemed suddenly to cease their efforts to escape from the great magnet's grip, and abruptly turned, paused, and then hurtled down with all their own force and that of the attracting magnet toward the giant machines below them whose great arms were destroying them. Stevens cried out hoarsely as he saw torpedo and bomb flash down and send a half-dozen of the great machines reeling and crashing down upon the city in flashes of bursting fire. At the same moment he was aware that their own craft was winning slowly out of the giant grip of the magnet, inch by inch, foot by foot, creeping upward and outward from that grip, while below the last scores of the attacking submarines were meeting their doom, crushed by the arms of the giant machines and annihilated by the purple-flaring bombs that rushed up toward them from the city below.

And now the great machines were striding toward his own craft, the last remaining one except for a few far across the city that were battling their way upward against others of the machines. Slowly, slowly, the submarine crept upward, while the mighty shapes whirled across the streets and globes of the city toward it. They were below it, now, were reaching up with gigantic arms, and Stevens stared down upon those upward-reaching arms in a strange apathy of despair. The battle was over, he knew, humanity's battle, lost now forever, its last chance flickered out. Up came the whirling arms, up, while still the submarine crept higher, and then one of them had struck it a great, glancing blow, in reaching for it, had knocked all in it to the floor, stunning Evans and his seaman and Stevens himself against the metal walls, and knocking, too, the submarine out of the last limits of the magnet's giant grip.

Its propellers whirling with sudden power, it shot out of that unseen hold, over the city, and Stevens raised his head, stunned and bleeding, to see Clinton standing at the wheel, to hear his wild shout as he sent the submarine racing above the city toward the great pit and the uprushing current at its center, toward the towering spire at that pit's rim, and the round, green-lit little control room at its top. Straight toward that ball-like room at the great spire's tip flashed the racing submarine, and Stevens glimpsed the mighty striding-machines, far across the city, abandoning the battle with the remaining few submarines, which shot sharply upward, to whirl after their own; saw rushing toward them from around the spire others of the giant machines, their vast arms upraised to grasp and crush the hurtling craft. But before they could grasp it, before their great arms could do ought more than graze along its sides, Clinton had sent the submarine flashing past them with a hoarse cry and had crashed it straight into the little room at the mighty tower's tip.

Through the metal walls of that room the hurtling submarine crashed as though through walls of paper, speeding still straight up and outward with the force of its tremendous impetus. To the half-conscious Stevens, crouched there. It seemed that for a single moment the whole world held its breath, and then he saw a fountain of brilliant green fire burst out and upward from the little control room at the great spire's top, felt a mighty, thundering detonation shake the waters about him, and then half glimpsed below him the sea's bottom and the great city upon it heaving, rumpling, breaking and crashing, as that city broke up and was annihilated by a tremendous uprush of dazzling fires from beneath it--broke up and was annihilated, as he knew, by the explosion of the mighty generator beneath it, whose titanic, pent-up energies the wrecking of the little control room had released--broke up and was annihilated, Stevens knew, as _all_ the cities of the slug-people had been in that moment, when the mighty generators beneath each of those cities exploded likewise, the prisoned energies of all of them released by the wrecking of the little room from which all had been controlled. In all the far-flung deeps of earth's seas the cities of the slug-people and all their hideous hordes had met annihilation in that tremendous moment, he knew. The earth shuddered and swayed beneath those simultaneous, titanic cataclysms; the sea's whole floor rolled and shook; and then, as the submarine was flung wildly upward by the terrific convulsions of the waters, the vast fiery uprush of destruction beneath faded from his eyes.

Then Stevens felt his senses failing him, sank backward and was but dimly conscious of the waters outside the submarine roaring wildly as it shot upward with terrific speed. For a time that seemed endless to his darkened mind that roaring continued, and then abruptly came silence, and a great shock and splash. Then he felt hands upon him, and hoarse voices shouting in his ears, heard the doors above clanging open, admitting a flood of sunlight and clean fresh air upon him, and then he knew no more.

Sunset was flaming red in the west once more when Clinton and Stevens stood together again on the submarine's narrow deck, watching the preparations for its homeward voyage. Behind it floated a bare dozen of other long steel craft, as scarred and battered as itself, flung up and saved like itself by that last great convulsion of the waters--a dozen only, the last remnant of the mighty fleet of hundreds that had dived to the attack a scant few hours before. Even as they watched, three of those craft were moving away on their own homeward journey, toward the west, toward the sunset, over the waters that were now miraculously calmed and smoothened. Their last rejoicing farewells came faintly over those waters as they went, and then they were passing from sight, dark blots against the brilliance of the western sky, dwindling and vanishing.

There came into the minds of both men, as they gazed across the peaceful waters, a wonder as to what frantic outbursts of joy were shaking the peoples of earth to see those waters calmed thus, to see their terrible rise thus halted. There came into their minds a vision of what might have been, of the seas that might have whelmed a planet, with a strange and terrible race triumphant and supreme upon it, and then one of what would be, when the hordes of fugitives, half hoping, half doubting, would creep back from their hills and mountains of refuge toward their deserted lands and cities, when the places that were silent now and dead would be ringing again with life, when all the terror that had riven earth would be but a thing of the remembered past.

Then these things slipped from the minds of both and they turned toward the east as their craft, and those behind it, moved away in that direction. Onward through the waters they moved, their propellers turning faster and faster, little waves breaking from either side of their prows as they clove the sea. The brilliance faded from the sky behind the two men, as the little fleet moved on, and the gathering night closed down upon the world, star-embroidered. But the two standing there alone on the little vessel's deck were silent still, and unmoving, gazing out into the darkness across the calm waters with the silence of men whose minds held things too great for speech.
