"Come, George! We go down, quickly now."
e ran to the pit. It had expanded to a great round hole some six feet wide and equally as deep. Glora let herself down, peered anxiously beneath her, and dropped. Alan and I followed. We jammed the pit; but as we stood there, the walls were receding and lifting.
I had remarked Glora's downward glance, and shuddered. Suppose, in some slightly smaller size, Babs had been here among these rocks!
The pit widened steadily. The movement was far swifter now. We stood presently in a great circular valley. It seemed fully a mile in diameter, with huge encircling walls like a crater rim towering thousands of feet into the air. We ran along the base of one expanding wall, following Glora.
I noticed now that overhead the turgid murk had turned into the blue of distance. A sky. It was faintly sky-blue, and there seemed a haze in it, almost as though clouds were forming. It had been cold when we started. The exertion had kept us fairly comfortable; but now I realized that the air was far warmer. It was a different air, more humid, and I thought the smell of moist earth was in it. Rocks and boulders were strewn here on the floor of this giant valley, and I saw occasional pools of water. There had been rain recently!
The realization came with a shock of surprise. This was a new world! A faint, luminous twilight was around us. And then I noticed that the light was not altogether coming from overhead. It seemed inherent to the rocks themselves. They glowed very faintly luminous, as though phosphorescent.
We were now well embarked upon this strange journey. We spoke seldom. Glora was intent upon guiding us. She was trying to make the best possible speed. I realized that it was a case of judgment, as well as physical haste. We had dropped into that six-foot pit. Had we waited a few moments longer, the depth would have been a hundred feet, two hundred, a thousand! It would have involved hours of arduous descent—if we had lingered until we were a trifle smaller!
