once the eyes darted sideways, and something white ran past me. I turned with my heart in my mouth, and saw a queer little ape-like figure,8 its head held down in a peculiar manner, running across the sunlit space behind me. It blundered against a block of granite, staggered aside, and in a moment was hidden in a black shadow beneath another pile of ruined masonry.

“My impression of it is, of course, imperfect; but I know it was a dull white, and had strange large greyish-red eyes; also that there was flaxen hair on its head and down its back. But, as I say, it went too fast for me to see distinctly. I cannot even say whether it ran on all-fours, or only with its forearms held very low. After an instant’s pause I followed it into the second heap of ruins. I could not find it at first; but, after a time in the profound obscurity, I came upon one of those round well-like openings of which I have told you, half closed by a fallen pillar. A sudden thought came to me. Could this Thing have vanished down the shaft? I lit a match, and, looking down, I saw a small, white, moving creature, with large bright eyes which regarded me steadfastly as it retreated. It made me shudder. It was so like a human spider! It was clambering down the wall, and now I saw for the first time a number of metal foot and hand rests forming a kind of ladder down the shaft. Then the light burned my fingers and fell out of my hand, going out as it dropped, and when I had lit another the little monster had disappeared.

“I do not know how long I sat peering down that well. It was not for some time that I could succeed in persuading myself that the thing I had seen was human. But, gradually, the truth dawned on me: that Man had not remained one species, but had differentiated into two distinct animals: that my graceful children of the Upper-world were not the sole descendants of our generation, but that this bleached, obscene, nocturnal Thing, which had flashed before me, was also heir to all the ages.

“I thought of the flickering pillarsbc and of my theory of an underground ventilation. I began to suspect their true import. And what, I wondered, was this Lemurbd doing in my scheme of a perfectly balanced organization? How was it related to the indolent serenity of the beautiful Upper-worlders? And what was hidden down there, at the foot of that shaft? I sat upon the edge of the well telling myself that, at any rate, there was nothing to fear, and that there I must descend for the solution of my difficulties. And withalbe I was absolutely afraid to go! As I hesitated, two of the beautiful Upperworld people came running in their amorous sport across the daylight in the shadow. The male pursued the female, flinging flowers at her as he ran.

“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 problem9 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 look common in most animals that live largely in the dark—the white fish of the Kentucky cavesbf ,for instance. Then, those large eyes, with that capacity for reflecting light, are common features of nocturnal things—witness
