im all through and resolved, presently, into a measured, tingling
beat.

His thoughts raced. He knew that those minute particles of matter, the
atoms of his body, were being compacted; he sensed that his legs were
rigid, his body stiff, his eyes clamped ahead in a glazed stare. He
was only half-conscious of the objects outside, but the dim sight of
them was fantastic and nauseous.

There was Hagendorff's face peering in at him--growing! Swelling as
the cat's body had swollen; and yet receding and rising until Garth,
momentarily forgetting that he was the one whose size was changing,
thought that the man's titanic body would fill the room. But the room
was growing, too: the stools were becoming leviathans of wood, the
walls were like cliffs, the compact switchboard was a large surface
of black, and the chamber in which he stood grew into a high-roofed
vault, its sides shooting up and retreating as if shoved by invisible
hands.

And still he sank, and still the terrible light devoured him.

Suddenly a delirious sensation engulfed him; his senses went reeling
away, and he staggered. Then with a wrench he came to. As he regained
control of his mind he knew the lever had been switched off and the
process completed.

He found that he was gasping. He passed a hand over his sweat-studded
face and looked around.

Outside was the room of a giant. And in a moment a giant became
visible. His vast bulk filled the chamber's doorway; his mammoth face
peered in. Garth's eardrums quivered from a deep bass rumble, sounding
like thunder on a distant horizon.

"Are you all right, Howard?"

A finger half the length of his own arm reached forward and prodded
him. For a second Garth could do nothing but stare at it. It brought
home to him starkly the puny size of his body, only two feet in
height. He felt suddenly afraid. But that was foolish, he thought; and
he laughed, his voice ludicrously high and shrill.

"I'm all right," he cried. "But I can hardly understand you. If I were
much smaller, I probably couldn't--your voice'd seem so deep. Gangway,
Hagendorff, I'm coming out!"

His eyes were just below the level of the giant's shoulders. He
stepped from the black chamber and stared amazedly at the room, at the
chairs, the objects in it--at the laboratory table on which he was
standing, along which he might have sprinted thirty yards. A surge of
exultant animal spirits flowed through hi
