m. His dream had become a
reality; the machine had passed its last test! His body was sound and
whole; he felt perfectly natural; he had not changed, save in size;
and in size he was like Gulliver, confronted with a Brobdingnagian
room!

He hurdled a five-inch-high box of tools, ran down the creaking table
and stood laughing in front of a rack of test tubes half as high as he
was. Three strides took Hagendorff opposite him; and from above the
thunderous voice rumbled:

"What were your sensations?"

"Probably as close as man'll ever get to the feelings of a spark of
electricity!" the midget replied. "But bearable, though I was freezing
and burning at the same time. My body was rigid, paralyzed--just like
the animals we used. I couldn't move."

"You're sure you couldn't move? You were helpless?"

* * * * *

The booming voice throbbed with sudden interest. Garth looked up
curiously. "No," he repeated. "I couldn't move. But lift me down,
Hagendorff. I want to take a walk on the floor."

A hand wrapped around his body, tensed and strained upwards. The
two-foot-high man was not quite pulled off the table. Then Hagendorff
grunted and relaxed his grasp.

"I had forgotten," he rumbled. "Your weight remains the same. You are
one-third my size, yet you weigh almost as much as I do. Weight, which
is the sum of the mass of all the atoms in you, is not, naturally,
affected by compacting those atoms."

It was only by a great effort that he was able to deposit the manikin
on the floor.

For a while Garth strolled around, savoring to their full the
fantastic sensations his diminished stature gave him, at once amused
and somehow frightened by the overwhelming size of the laboratory. To
his eyes, the tables were like bridges; Hagendorff's broad figure
loomed monstrously over him, and the guinea pigs and rabbits in their
cages seemed as big as fair-sized dogs. With a grin, he looked up at
the giant who was his assistant.

"Think I'll make the return trip, and give you a chance," he said.
"I've had my share, and the process has been proven. It's weird, being
down in this new world all alone. I'd hate to think what would happen
if a rat came along!"

Silently, Hagendorff stooped and grasped him again. But Garth, when he
stood once more inside the chamber, regarded his huge, rough-moulded
face curiously.

"Say," he said, puzzled, "your hands are trembling like the devil!
What's wrong? You're m
