he effect wrought by the throwing of that great switch was almost indescribable.
In a flash, as though all had been struck at once by a giant's hand, every Rogan in the mob shot toward the floor, long thin legs caving under him as if turned to water. Writhing feebly, they endeavored to get up, but could not; and, still weakly ferocious, began to creep toward the Earthman like huge-headed worms.
Brand himself had been thrown to the floor with the falling of that switch. He had felt as though an invisible ocean had been poured on him, weighting him down intolerably. To move arms or legs required enormous effort; and to get up on his feet again was like rising under a two-hundred-pound pack.
The movement of the switch, he saw, had cut off the gravity reducing apparatus of the Rogans—whatever that might consist of. They were now, abruptly, subjected to the full force of gravity exerted by Jupiter's great mass. They could no more stand erect on their tottering, lofty legs than they could fly.
But, though greatly handicapped by the gravity pull, they were still not entirely helpless. Like huge, long insects they continued to worm their way toward Brand, using their four arms and their boneless legs to help urge them over the flooring. And in their rear the Rogan guards struggled to lift their tubes and level them at the escaped prisoner.
Prompt to avoid that, Brand went down on his hands and knees. Thus he was shielded by the foremost crawling Rogans: the ones in the rear, with the tubes, could not raise themselves high enough to bore down over their fellows' heads at the Earthman.
Squatting on his knees, Brand awaited the first resolute crawlers. And, on his knees, whirling the now thrice weighty bar at heads that were conveniently low enough to be accessible, he began his last stand.
