We started. My impression now is that we were walking. I could feel a part of my body in movement, quite as though of my volition I were moving my legs. A sense of lightness again possessed me; a lack of stability. But I could feel solidity beneath me, and I was moving upon it. We walked then, down the hill. There was vegetation; things, let me say, seemed rooted within the ground. But they bent from our advance as though with a knowledge and a fear that we might tread upon them. The scene was no longer empty. A rolling land, with what might have been a mountain range rising in the distance. All in that half-light of seeming phosphorescence. I noticed now that the familiar convexity of earth was gone. The scene had a queer concavity; to the limit of my vision it stretched _upward_; as though we were upon the inner surface of some vast hollow globe with the concave darkness overhead coming down to meet it. A hollow globe within which we were standing; but it seemed of infinite size. Not far away now was that region which first I thought was water. We passed over it--partly through it. I felt the resistance against me. Like water with no wetness; but to my sight it was a heavy fog lying upon the land. Its breath was oppressive; I was glad when we were past it, emerging again into the twilight with a city before us. A city! Houses--human habitations! I knew it--divined it with a new mental alertness; and Ala's words presently confirmed my thoughts. "Our Big-City," she said. * * * * * Before us lay an area upon which was spread a confusion of globes. Circular, yet visually flat of depth. In size I found them later to be, from the smallest some twice my own height, to others I would in my own world have said to be a hundred feet in diameter. Opaque grey globes, of a material unnameable. Of every size they lay seemingly strewn about; and in places piled one upon the other. All of grey color that glistened with a sheen of iridescence. The Big-City. Diminished by distance it seemed indeed as though a thousand varying-sized soap bubbles, smoke-filled, lay piled together. And the whole flattened, queerly unnatural like a picture with a wrong perspective. The globes were scattered about; but as we approached I saw open spaces twisting among them like tortuous streets. Horizontal streets; and vertical streets as well. Abruptly I realized that this realm was not cast like my own upon a single plane. On earth we move chiefly in a world of two dimensions--only in the air or water do we have the freedom of three. Here, the vertical and the horizontal seemed no different. Bee said, "The Big-City. Houses--" Her voice trailed away into wonderment. From our presently nearer viewpoint, movement showed in the city; beings--people like ourselves--moving about the streets. And soon we were among the globes--within the city.
