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
