enormous pillars of
Polter's legs towered straight up from near at hand. Alan was aware of
himself screaming:

"George--out! You're too large! Too large for in here!"

As though his microscopic voice could reach me--my head hundred of
feet above him. But he screamed it again. This was all in a few
horrible moments, though it seemed to the three watchers an eternity.
Alan was helpless to aid me; they had taken all of the enlarging drug
they had.

Then they saw Polter cast me off. I lurched and struck, with my
shoulders wedged against the cliff directly over where they crouched.
The overhead sky was darkened as Polter scrambled upward.

Alan was still screaming futilely, "George--up! Get out!"

Babs huddled with white, horrified face, staring. Then I went out
after Polter. My disappearing legs were great dark blurs in the sky.
Alan saw the valley now contracted to a thousand feet of width, with
its cliffs equally as high. Then everything was smaller.... The sky
overhead went dark again; from cliff to cliff a segment of our rolling
bodies momentarily spanned the opening.

And presently Alan realized that the valley had narrowed to a pit. He
stood up. "Hurry! Now we can get out after them. Up there!"

The opening above was empty. Polter and I were fighting some distance
away....

Dr. Kent was soon large enough to scramble out of the pit. Alan handed
the little Babs up to him and followed. Alan saw that they were now in
a long gully, blind at one end with a five hundred-foot perpendicular
cliff. Against the wall, the titanic form of Polter stood at bay. And
I was fronting him. The summit of the cliff was lower than our waists.
Triumph swept Alan; he saw that I was the larger! As Polter bored into
me my backward step crossed the full width of the gully. Alan shouted:

"Down! Babs--Father!"

They had barely time to flatten themselves in a narrow crevice between
upstanding rocks before my foot crashed down. For an instant the sole
of my boot formed a flat black ceiling as it trod and spanned the
rocks. Then it lifted; was gone with a blurred swoop. They saw the
white blur of my hand come down and snatch a tremendous boulder,
raising it with a great sweep of movement into the sky. They saw me
crash it against Polter; but it only struck his shoulder. He roared
with anger. The whole sky was roaring and rumbling with our shouts and
our panting breathing, and the ground was cla
