"Faster!" urged Glora. We ran, and reached the railing. It was higher than our heads. We ran under it, and out upon the white slab--a level surface, larger now than the whole dome-room had been.
Glora, like a fawn ran in advance of us, her draperies flying in the wind. She turned to look back.
"Faster! Faster--or it will be too hard a climb!"
Ahead lay a golden mound of rock. It was widening; raising its top steadily higher. Beyond it and over it was a vast dim distance. We reached the rock, breathless, winded. It was a jagged mound like a great fifty-foot butte. We plunged upon it, began climbing.
The ascent was steep; precipitous in places. There were little gullies, which expanded as we climbed up them. It seemed that we should never reach the top, but at last we were there. I was aware that the drug had ceased its action. The yellow rocky ground was no longer expanding.
We came to the summit and stood to get back our breath. And Alan and I gazed with awe upon the top of a rocky hill. Little buttes and strewn boulders lay everywhere. It was all naked rock, ridged and pitted, and everywhere yellow-tinged.
Overhead was distance. I could not call it a sky. A blur was there--something almost but not quite distinguishable. Then I thought that I could make out a more solid blur which might be the lower lens of the microscope above us. And there were blurred, very distant spots of light, like huge suns masked by a haze, and I knew that they were the hooded lights of the laboratory room.
Before us, over the brink of a five hundred-foot cliff, a great glistening white plain stretched into the distance. I seemed to see where it ended in a murky blur. And far higher than our own hilltop level a horizontal streak marked the rope railing of the slab.
"Well," said Alan, "we're here." He gazed behind us, back across the rocky summit which seemed several hundred feet across to its opposite brink. He was smiling, but the smile faded. "Now what, Glora? Another pellet?"
"No. Not yet. There is a place where we go down. It is marked in my mind."
I had a sudden ominous sense that we three were not alone up here. Glora led us back from the cliff. As we picked our way among the naked crags, it seemed behind each of them an enemy might be lurking.
