"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 b.u.t.te. 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 b.u.t.tes 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.

"Glora, do you know if any of Dr. Polter's men have the drug? I mean, do they come in and out here?"

She shook her head. "I think not. He lets no one have the drug. He trusts not any one. I stole it; I will tell you later. Much I have to tell you before we arrive."

Alan made a sudden sidewise leap, and dashed around a rock. He came back to us, smiling ruefully.

"Gets on your nerves, all this. I had the same idea you did, George.

Might be someone around here. But I guess not." He took Glora's hand and they walked in advance of me. "We haven't thanked you yet, Glora."

"Not needed. I came for help from your world. I could not get back to my own, and I followed the Doctor Polter when he came outward. He has made my world, my people, his slaves. I came for help. And because I have helped you needs no thanks."

"But we do thank you, Glora." Alan turned his flushed, earnest face back to me. I thought I had never seen him so handsome, with his boyish, rugged features, and shock of tousled brown hair. The grimness of adventure was upon him, but in his eyes there was something else.

It was not for me to see it. That was for Glora; and I think that even then its presence and its meaning did not escape her.

"Stay close, George."

"Yes."

We reached a little gully near the center of the hilltop. It was some twenty feet deep. Glora paused.

"We descend here."

The gully was an unmistakable landmark--open at one end, forty feet long, with the other end terminating in a blind wall, smoothly precipitous. We retraced our steps, entered the gully at its open end, and walked its length. Glora paused by the wall which now loomed above us.

"A pit is here--a hole. I cannot tell just how large it will look when we are in this size."

We found and stood over it--a foot-wide circular hole extending downward. Alan abruptly knelt and shoved his hand and arm into it, but Glora sprang at him.

"Don't do that!"

"Why not? Is this it? How deep is it?"

She retorted sharply, "The Doctor Polter is ahead of us. How far away in size, who knows? Do you want to crush him, and crush that young girl with him?"

Alan's jaw dropped. "Good Lord!"

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 precipice 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 go 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 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 phosph.o.r.escent.

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!

We took other pellets. We traveled perhaps an hour more. There were many instances of Glora's skill. We squeezed into a gully and waited until it widened; we leaped little expanding caverns; we slid down a smooth yellowish slide of rock like a child's toboggan, and saw it behind and over us, rising to become a great spreading ramp extending upward into the blue of the sky. Now, up there, little sailing white clouds were visible. And down where we stood it was deep twilight, queerly silvery with the phosph.o.r.escence from the luminous rocks as though some hidden moon were shining.

Strange, new world! I suddenly envisaged the full strangeness of it.

Around me were spreading miles of barren, naked landscape. I gazed off to where, across the rugged plateau we were traversing, there was a range of hills. Behind and above them were mountains; serrated tiers, higher and more distant. An infinite spread of landscape! And, as we dwindled, still other vast reaches opened before us. I gazed overhead.

Was it--compared to my stature now--a thousand miles, perhaps even a million miles up to where we had been two or three hours ago? I think so.

Then suddenly I caught the other viewpoint. This was all only an inch of golden quartz--if one were large enough to see it that way!

Alan had been trying to memorize the main topographical features of our route. It was not as difficult as it seemed at first. We were always far larger than normal to our environment. The main distinguishing characteristics of the landscape were obvious--the blind gully, with the round pit, for instance, or the ramp-slide.
