"More signs of violence," cried Pillbot. "But that action won't appease It—we must get out of here—"

Even as he spoke there was a thunderous crackling and roaring. Harper felt himself flying about, and for an instant of awful vertigo he did not know up from down. Forces seemed to be tearing at him. He felt as though he were a piece of iron being attracted simultaneously in several directions by powerful electro magnets.

There was a flare of colored lights, a deafening detonation—and he felt himself knocked breathless against a wall.

He picked himself up, looked around.


On one side of him was the familiar south wall of the laboratory. To the north, east and west was—open air. He was standing on a section of laboratory flooring that jutted out over empty space from the wall. His desk was a few feet away, right at the edge of the jutting floor. Gault and Pillbot were picking themselves up to one side of the desk.

The pair looked over the edge of the floor, then recoiled, frenziedly hugging the flooring under them.

Harper crawled over, looked over the edge, quickly backed away. Several hundred feet below, the traffic of the city roared!

Gault went over to the door in the one wall, opened it, then stepped back quickly, his face pale.

"The laboratory has been turned inside out!" he shouted. "We are on the outside!"
