"Through all that day we watched the great current shooting ceaselessly up through the calmer waters about it, and through the next, and knew that on earth the waters must already be rising inch by inch, and that they would creep up, inch by inch and foot by foot, until they had covered all earth's fields and forests and cities and highest peaks, until earth itself was covered miles deep with this sea of hell, and at its bottom the slug-people reigned triumphant. Then, at last, the agony of our despair broke forth, and we seized at once upon a chance for escape which presented itself.

"It was in a suggestion made by Evans, the submarine's commander, that we saw our chance. His plan seemed suicidal, almost, but it was still a chance, so we ignored the risks. Waiting for some hours until the street outside our prison had emptied somewhat of the passing slug-people, we took from the submarine's equipment a long, slender drill of steel, and with this, held and guided by two seamen, set to work on the metal wall of our prison. At first the metal seemed too hard for the drill to affect, but gradually it bit into it, deeper and deeper. Inch by inch it crept on into the thick metal wall, while we watched anxiously. The hours were passing swiftly, and in the distance we could see the mighty current from the pit still roaring upward, but at last, when it seemed that the wall was too thick for us, the drill broke through.

"Before we could withdraw it, it had been knocked inward toward us with terrific force by the pressure of the waters outside, and through the two-inch hole it left came shooting inward a solid stream of water of terrific force. In a moment that jet had filled the great room to a depth of a foot, and hastily we splashed toward our submarine, clambering up and inside it and shutting tightly the heavy doors. From the port-holes we could see the waters in the room swiftly rising, until within a few more minutes they had risen sufficiently to float the submarine, which had been lying on the bare metal floor of the great room.

"Instantly Evans gave an order, and at once the craft's motors began to hum and its reversed propellers to thrash the waters, backing us against the wall opposite the great doors. There we paused a moment, and then another order sent the boat leaping across the great room through the waters like a living thing, toward the inner of the two great doors, which could be opened only from the outside. With a great ramming shock the craft's prow struck the door; for this was our plan, to batter down the two doors if possible and make our escape. The door, we saw, had been shaken by the blow, its thick, transparent metal deeply dented, but it still hung fast; so again the submarine retreated to the opposite wall and again leapt forward to crash against the barrier.

"At the second blow there was a clash of metal against the sides of our craft and we saw that the great door had crumpled beneath the two blows. Only the outer door barred our escape, now, and excitedly we watched as the submarine reversed once more and leapt forward against that last barrier. We struck it with a great jar that again knocked us all from our feet but did not dislodge the door, and now there came a sudden exclamation from Evans as he saw, through the port-hole, a group of the slug-creatures who had stopped outside and were peering in toward us. As our craft leaped forward in another dash against the thick metal we saw them hastening down the street, and a moment later saw striding over the city from the distant spire three of the great machines that guarded that spire, hastening across the city in gigantic strides toward us!

"In spite of our second blow the outer door still hung fast, and swiftly the hastening machines were nearing us. By now the submarine's motors were humming at their highest power, and as Evans hoarsely shouted the order, the craft backed against the wall, hesitated for a moment, and then leapt forward through the waters toward the outer door for a third time, with all the force of its whirling propellers. As we shot forward I saw, not a thousand feet away, the great machines that were bending down toward our prison, and then there came a great crash and jar, the great metal door was crumpled aside like one of cardboard, and our submarine shot out into the open waters. Swiftly toward us reached the great arm of the foremost giant machine, and for a moment, as we slanted sharply upward, we felt the end of that arm graze against the side of our craft. Then we had torn past it and were shooting up through the waters toward the surface at a steep angle, up until the city of globes and the white radiance that bathed it were lost from view beneath us.

"Up, up, up—until at last our craft shot bodily out of the waters into the sunlight and clean air. Panting and half senseless we ripped the doors open, breathed deep of the salt breezes. The waters on which the submarine floated were running in great seas, and from a hasty consultation of our instruments we saw that already the sea's level had risen several feet, and knew, too, as no others did, what was causing that rise and bringing doom upon the earth. So we set our course back toward England and raced homeward through the rising waters to bring our warning to the world, for in the general panic our radio calls received no answer. East and southeast we held, and at last were sweeping into the harbor of London, where, after a frantic hour, Evans, Lewis and I were able to convince the naval authorities of the truth of our story, were able to convince them that the only remaining chance to prevent the destruction of all our world is to descend into the depths in force and destroy or attempt to destroy the great generator which we saw in action there in the deeps of the Atlantic, and after it the others.

"This was but a few hours ago, Stevens, and in those hours and while I have talked here with you the submarines of all the British fleet, the new-type submersibles which alone can descend into those terrific depths, have been gathered in the flooded Thames and soon will sail, with the submarines of all other countries that can be gathered, to make one last attempt to save our world. I had an hour or more, I knew, so while Lewis hastened away in search of his family. I, who have none, came here in the hope of finding you, Stevens, knowing that you would be with us if you could. And so now you know what terror it is that is flooding our world, that is rising toward the death of all humanity, and toward which, at the bottom of the Atlantic, we sail within the hour, for one final desperate attempt to halt this rising doom."

Clinton rose to his feet with these words, gazed silently out over the red-lit city, over the rising floods that rushed through its streets and sent the fear-crazed fugitives outside shouting down those streets in blind horror. Stevens, too, arose, gazed with him, and then with a common impulse and with no spoken word they had turned toward the door, toward the street. Half an hour later they had won their way across the dark, flooded wilderness that was London toward the rank on rank of long, grim steel hulls that swung by the shores of the swollen Thames, and a few minutes later they stood in the narrow control room of one of those hulls as they swung in formation out to the open sea, more than a hundred strong.

Out, out, they moved, into the darkness of the surging channel, and then southward around the foreland, where there fell in at the side of their formation a similar formation of an equal number of craft, the combined Atlantic and Mediterranean submarine fleets of France, Germany and Italy. Still the combined fleets moved on, toward the west, through the surging, tremendous waves, in steady, unchanging formation. Onward through the hours of the night they moved, and on into the day, still westward, and through the night again until at last, at dawn, there could be seen on the waters far ahead a multitude of long black spots, long steel hulls like their own, the great American submarine fleet racing eastward in answer to the call for help. The two fleets met, coalesced, and then, in one great triangular formation, more than three hundred strong, turned and headed north. The morning waned, and the afternoon, and sunset came, but still those gathered scores of long grim craft forged north and north, toward the Nelsen Deeps and what lay at their bottom, toward the last great battle of humanity to save its drowning world.
