That gave me a start. By dawn! We had been traveling four or five hours. It was already dawn up there now!
"No," Glora explained, "the time in here is different. A different time-rate. I do not know how much difference. My world speeds faster; yours is very slow. It is not the dawn up there quite yet."
Again my mind strove to encompass these things—so strange. A faster time-rate prevailed in here? Then our lives were passing more quickly. We were living, experiencing things, compressed into a shorter interval. It was not apparent: there was nothing to which comparison could be made. I recalled Alan's description of Polter—not thirty years old as he should have been, but nearer fifty. I could understand that, now. A day in here was equal to only a few hours on our gigantic world outside.
We walked the length of the tunnel. I suppose it was a quarter of a mile, to us in this size. It wound through the cliff with a steady downward slope. And suddenly I realized that we had turned downward nearly half the diameter of a circle! We had turned over—or at least it seemed so. But the gravity was the same. I had noticed from the beginning very little change.
The realization of this tunnel brought a mental confusion. I lost all sense of direction. The outer world of Earth was under my feet, instead of overhead. Then we went level. I forgot the confusion: this was normality here. We turned upward a little. Cross tunnels intersected ours at intervals. I saw caverns, open, widened tunnels, as though this mountain were honeycombed.
"Look!" said Glora. "There is the way out. All these passages lead the same way."
There was a glow of light ahead. I recall that I was at that moment fumbling at my belt in two small compartments in which I was carrying the two vials of the drugs which Glora had given me. Alan wore the same sort of belt. We had found them in the wrecked dome-room. I heard a click on the ground at my feet. I was about to stoop to see what I had kicked—only a loose stone, perhaps—but Glora's words distracted me. I did not stoop. If only I had, how different events might have been!
The glow of light ahead of us widened as we approached, and presently we stood at the end of the tunnel. A spread of open distance was outside. We were on a ledge of a steep rocky wall some fifty feet above a wide level landscape. Vegetation! I saw trees—a forest off to the left. A range of naked hills lay behind it. A mile away, in front and to the right, a little town nestled on the shore of shining water. There was starlight on the water! And over it a vast blue-purple sky was studded with stars.
I gazed, with that first sudden shock of emotion, into the infinite depths of interplanetary space! Light years of distance. Gigantic worlds, blazing suns off there shrunken by distance now to little points of light. A universe was here!
But this was an inch of golden quartz!
