Things happened while she slept, many things. Certain endocrine extracts accelerated her metabolism astonishingly. Within half an hour her heart was pumping blood through her body two hundred beats per minute. An hour later it reached its full rate, almost one thousand contractions every sixty seconds. All her other metabolic functions increased accordingly, and Sophia slept deeply for a week of subjective time—in hours. The same machine which had gleaned everything from her mind far more accurately than a battery of tests, a refinement of the electro-encephalogram, was now played in reverse, giving back to Sophia everything it had taken plus electrospool after electrospool of science, mathematics, logic, economics, history (Marxian, these last two), languages (including English), semantics and certain specialized knowledge she would need later on the Stalintrek.

Still sleeping, Sophia was bathed in a warm whirlpool of soothing liquid; rubbed, massaged, her muscle-toning begun while she rested and regained her strength. Three hours later, objective time, she awoke with a headache and with more thoughts spinning around madly inside her brain than she ever knew existed. Gingerly, she tried standing again, lifting herself nude and dripping wet from a tub of steaming amber stuff. She stood, stretched, permitted her fright to vanish with a quick wave of vertigo which engulfed her. She had been fed intravenously, but a tremendous hunger possessed her. Before eating, however, she was to find herself in a gymnasium, the air close and stifling. She was massaged again, told to do certain exercises which seemed simple but which she found extremely difficult, forced to run until she thought she would collapse, with her legs, dragging like lead.

She understood, now. Somehow she knew she was on Jupiter, the fifth and largest planet, where the force of gravity is so much greater than on Earth that it is an effort even to walk. She also knew that her metabolic rate had been accelerated beyond all comprehension and that in a comparatively short time—objective time—she would have thrice her original strength. All this she knew without knowing how she knew, and that was the most staggering fact of all. She did what her curt instructors bid, then dragged her aching muscles and her headache into a dining room where tired, forlorn-looking men sat around eating. Well, the food at least was good. Sophia attacked it ravenously.


t did not take Temple long to realize that the creature running downhill at him, leaving a crushed and broken wake in the purple and green grass, was not human. At first Temple toyed with the idea of a man on horseback, for the creature ran on four limbs and had two left over as arms. Temple gaped.

The whole thing was one piece!

Centaur?

Hardly. Too small, for one thing. No bigger than a man, despite the three pairs of limbs. And then Temple had time to gape no longer, for the creature, whatever it was, flashed past him at what he now had to consider a gallop.

More followed. Different. Temple stared and stared. One could have been a great, sentient hoop, rolling downhill and gathering momentum. If he carried the wheel analogy further, a huge eye stared at him from where the hub would have been. Something else followed with kangaroo leaps. One thick-thewed leg propelled it in tremendous, fifteen-foot hopping strides while its small, flapper-like arms beat the air prodigiously.
