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.

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

"Don't do that!"

"Why not? 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 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
