“They seemed distressed to find me, my arm against the overturned pillar, peering down the well. Apparently it was considered bad form to remark these apertures; for when I pointed to this one, and tried to frame a question about it in their tongue, they were still more visibly distressed and turned away. But they were interested by my matches, and I struck some to amuse them. I tried them again about the well, and again I failed. So presently I left them, meaning to go back to Weena, and see what I could get from her. But my mind was already in revolution; my guesses and impressions were slipping and sliding to a new adjustment. I had now a clue to the import of these wells, to the ventilating towers, to the mystery of the ghosts; to say nothing of a hint at the meaning of the bronze gates and the fate of the Time Machine! And very vaguely there came a suggestion towards the solution of the economic problem that had puzzled me. “Here was the new view. Plainly, this second species of Man was subterranean. There were three circumstances in particular which made me think that its rare emergence above ground was the outcome of a long-continued underground habit. In the first place, there was the bleached look common in most animals that live largely in the dark—the white fish of the Kentucky caves, for instance. Then, those large eyes, with that capacity for reflecting light, are common features of nocturnal things—witness the owl and the cat. And last of all, that evident confusion in the sunshine, that hasty yet fumbling awkward flight towards dark shadow, and that peculiar carriage of the head while in the light—all reinforced the theory of an extreme sensitiveness of the retina. “Beneath my feet, then, the earth must be tunnelled enormously, and these tunnellings were the habitat of the New Race. The presence of ventilating shafts and wells along the hill slopes—everywhere, in fact, except along the river valley—showed how universal were its ramifications. What so natural, then, as to assume that it was in this artificial Underworld that such work as was necessary to the comfort of the daylight race was done? The notion was so plausible that I at once accepted it, and went on to assume the _how_ of this splitting of the human species. I dare say you will anticipate the shape of my theory; though, for myself, I very soon felt that it fell far short of the truth.
