the celestial globe, computed it, and jotted some figures down on a pad. He looked over his shoulder at the girl. "We'll have to fall free for a moment to go into hyper-space, so brace yourself." He cut the converter entirely and his stomach reacted like that of a diver with the bends. It almost literally tied itself in knots. The girl moaned in pain and grasped the sides of the shock chair. Pell's jaw hardened as he wound up the Thelmard Generator to build up the field about the ship. The familiar stars danced and flickered; then disappeared. He sighed and stepped up the converter to one G acceleration. He arose from his chair wearily and shrugged from his heavy suit. Addressing the girl behind him, he said, "We won't be needing these things for awhile. You had better go back to the waist and look at Heintz." Pell turned and looked at her.

Pell savored the memory of her lips for a moment, then grimaced to himself. She was right, of course. He exhaled a cloud of smoke and watched its tendrils stream around the control panel and fluff against the plastine observation shield.

Men had been known to go mad from looking too long at the alien strangeness of this extra-dimensional space which was not for human eyes. Its very nothingness seemed to twist at one's mind. He glanced at his instruments, then at the celestial navigation globe. In normal space the ship had traveled some four and one-third light years. But in hyper-space it had moved very little during
