atory door was open and he
dashed for it. But, whether or not Hagendorff could see his frantic
retreat, he anticipated it, and with a reeling plunge he got there
first. Fumbling, he found the key in the hole and turned it. The room
was sealed.

Beginning then, the blind Hagendorff was a man berserk. With a sobbing
roar of pain and fury, he lashed round for the foot-high figure that
dodged and wheeled and zig-zagged to keep from his threshing arms and
his hands. A table crashed over, and a flood of chemicals mixed and
boiled on the floor; then another, as the giant blundered blindly into
it. The cages of animals split open, and guinea pigs, rabbits and
insects scuttled from their prisons, fleeing to the corners from the
wild plunges of the raging German.

Garth went reeling from a glancing blow, and fell against an
over-turned stool under a far table where he could hardly breathe for
the mixed odors of spilt chemicals. By some sixth sense, Hagendorff
seemed to locate him, for his huge body turned and came directly for
him.

But Garth did not wait. Seizing the stool he whirled it so that it
slid smash into the giant's legs. The man pitched over with a grunt,
striking the floor so hard that the planks shivered.

He did not rise. He lay there, in a wreckage of glass and splintered
wood and stinking chemicals, moaning slightly.

Garth wasted no time, but gripped a leg of the laboratory table,
shinned to the top and with frantic speed fixed his strand of wire
onto the control lever and round the supporting posts of the
instrument panel. Then he jumped for the dynamo switch, caught the
handle and jerked it down.

The drone of a generator surged through the room. Then the midget was
standing in the chamber, both ends of the wire in his hands; and his
heart was thudding madly as he pulled one of them.

It held. Over came the lever, halfway. The brilliant stream of the ray
poured down. Dimly the manikin glimpsed the chamber's walls sinking
down, the wreckage-strewn room outside diminishing to normal size.
Fiery pain throbbed through him, but it was lost in the exultation
that filled his mind as the seconds went by. He grew to two feet, two
and a half--three.

But beyond that he was not to go. The swaying shape of Hagendorff
loomed outside the cube. Aroused by the drone of the generator and
what it signified, the giant had floundered
