Let me emphasize that none of this had the quality of a dream; it was clear-cut, as vivid as anything I had ever experienced; my mind worked with an unusual precision and clarity, and not even a fleeting doubt came to me of the reality of my observations. "This is some sort of bombing attack," I remember reflecting, "some assault of super-monsters of the skies, perfected by a super science." And I did not have to be told the fact; I knew, as by an all-illuminating inner knowledge, that I had voyaged into the future.

Even as this realization came to me, I made another flight—and one that was in space more than in time. It did not surprise me, but I took it as the most natural thing in the world when I seemed to rise and go floating away through the air. It was still sunset-time, but I could see clearly enough as I went drifting at a height of several hundred yards above a vast desolated space near the junction of two rivers. Perhaps, however, "desolated" is not the word I should use; I should say, rather, "shattered, pulverized, obliterated," for a scene of more utter and hopeless ruin I have never seen nor imagined. Over an area of many square miles, there was nothing but heaps and mounds of broken stone, charred and crumbling brick, fire-scarred timbers, and huge contorted masses of rusting steel like the decaying bones of superhuman monsters. From the great height and extent of the piles of debris, and from the occasional sight of the splintered cornice of a roof or of some battered window-frame or door, I knew that this had once been a city, one of the world's greatest; but no other recognizable feature remained amid the gray masses of ruins, and the very streets and avenues had been erased. But here and there a tremendous crater, three hundred feet across and a hundred to a hundred and fifty feet deep, indicated the source of the destruction.

As if to reinforce the dread idea that had taken possession of my brain, one of the comet-like red prodigies went streaking across the sky even as I gazed down at the dead city; and I knew—as clearly as if I had seen the whole spectacle with my own eyes—that the missile had sprung from a source hundreds or thousands of miles away, possibly across the ocean; and that, laden with scores of tons of explosives, it had been hurled with unerring mechanical accuracy upon its mission of annihilation.

Then I seemed to float over vast distances of that sunset-tinted land, and saw great craters in the fields, and villages shot to ribbons, and farms abandoned; and the wild dogs fought for the wild cattle; and thistles grew deep on acres where wheat had been planted, and weeds sprouted thickly in the orchards, and blight and mildew competed for the crops. But though here and there I could see a dugout, with traces of fire and abandoned tools flung about at random, nowhere in all that dismal world did I observe a living man.

After a time I returned to a place near the ruined city by the two rivers; and in the rocky palisades above one of the streams, I made out some small circular holes barely large enough to admit a man. And, borne onward by some impulse of curiosity and despair, I entered one of these holes, and went downward, far downward into the dim recesses. And now for the first time, at a depth of hundreds of yards, I did at last encounter living men. My first thought was that I had gone back to the day of the cave-man, for a cave-like hollow had been scooped out in the solid rock. It was true that the few hundreds of people huddled together there had the dress and looks of moderns; it was true, also, that the gloom was lighted for them by electric bulbs, and that electric radiators kept them warm; yet Dante himself, in painting the ninth circle of his Inferno, could not have imagined a drearier and more despondent group than these that slouched and drooped and muttered in that cavernous recess, seated with their heads fallen low upon their knees, or moodily pacing back and forth like captives who can hope for no escape. "Here at least we will be safe from the sky marauders," I heard one of them muttering. Yet I could not help wondering what the mere safety of the body could mean when all the glories of man's civilization were annihilated.

There came a whirring in my head, and another blank interval; and when I regained my senses I knew that another period of time had passed, possibly months or even years. I stood on the palisade above the river, near the entrance of the caves; and the sun was bright above me; but there was no brightness in the men and women that trailed out of a small circular hole in the ground. Drab as dock-rats, and pasty pale of countenance as hospital inmates, and with bent backs and dirty, tattered clothes and a mouse-like nosing manner, they emerged with the wariness of hunted refugees; and they flung up their hands with low cries to shield them from the brilliance of the sun, to which they were evidently unaccustomed. From the packs on their backs and the bundles in their hands, I knew that they were emerging from their subterranean refuge, to try to begin a new life in the ravaged world above; and my heart went out to them, for I saw that, few as they were—not more than fifty in all—they were the sole survivors of a once-populous region, and would have a bitter fight to wage in the man-made wilderness that had been a world metropolis.

But as they roamed above through the waste of ash and rubble, and as they wandered abroad where the fields had been and saw how every brush and tree had been seared from the earth or poisoned by chemical brews, I knew that their fight was not merely a bitter one—it was hopeless. And I heard them muttering among themselves, "We have not even any tools!", and again, "We have no fuel left for the great machines!" ... For they had lived in a highly mechanical world, and the technicians who alone understood the workings of that world had all been destroyed, and the sources of power had all been cut off—and power was the food without which they could not long survive.

Unable to endure their haggard, hangdog looks and grim, despondent eyes, I went wandering far away, over the length and breadth of many lands. And nowhere did I see a factory that had not been hammered to dust, nor a village that had not been unroofed or burnt, nor a farm where the workers went humming on their merry, toilsome way. Yet here and there I did observe little knots of survivors. Sometimes they were half-clad groups, lean and ferocious as famished wolves, who roamed the houseless countryside with stones and clubs, hunting the wild birds and hares, or making meager meals from bark and roots. Sometimes three or four men, with the frenzied eyes and hysterical shrieks and shouts of maniacs, would emerge from a brush hut by a river flat. Sometimes little bands of men and women, in a dazed aimless way, would go wandering about a huge jagged hole in the ground, where their homes and their loved ones lay buried. I came upon solitary refugees high up on the scarred mountain slopes, with nothing but a staff to lean upon and a deer-skin to keep them warm. I saw more than one twisted form lying motionless at the foot of a precipice. I witnessed a battle between two half-crazed, ravenous bands, with murder, and cannibalism, and horrors too grisly to report. I observed brave men resolutely trying to till the soil, whose productive powers had been ruined by a poison spray from the sky; and I noted some who, though the fields remained fertile enough, had not the seed to plant; and others who had not the tools with which to plow and reap. And some who, with great labor, managed to produce enough for three or four mouths, had twenty or thirty to feed; and where the three or four might have lived, the twenty or thirty perished.

Then, with a great sadness, I knew that man, having become civilized, cannot make himself into a savage again. He has come to depend upon science for his sustenance, and when he himself has destroyed the means of employing that science, he is as a babe without milk. And it is not necessary to destroy all men in order to exterminate mankind; one need only take from him the prop of his mechanical inventions.
