We stood with the little pit before us, and another of the pellets ready.

"Now!" said Glora.

Again we took the drug, a somewhat larger pellet this time. The familiar sensations began. Everywhere the rocks were creeping with a slow inexorable movement, the landscape expanding around us. The gully walls drew back and upward. In a moment they were cliff walls and we were in a broad valley.

We had been standing close together. We had not moved, except to shift our feet as the expanding ground drew them apart. I became aware that Alan and Glora were a distance from me. Glora called:

"Come, George! We're going down—quickly now."

We 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 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 seemed hazy, 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 it was far warmer. This was 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.
