“ His house is in the sky, and when he steps out of it he can fly like a bird. And food. To grow food there is sunlight Earth never dreamed of. For heat and power there is sunlight to focus. Space is flooded with heat, irradiated with power—
"It's not child's play taming it, and those on the ground don't see it yet. But the next step of mankind is out into space, and it's never coming back."
Pierce, sitting in one of the shock tank armchairs, asked, "What part do you have in this?"
Bryce looked at him with a feeling almost of surprise, as if he had been called back from a long distance. ”

“ Persons would vanish abruptly and take up new names and identities in the obscure countries, others would draw out their heavy savings and take the first rocket out from Earth. There would be a new influx of refugees to the Belt, new settlers to be honest farmers and factory workers and repair men.
Yes, the situation was dramatic.
The day was a good day.
But as Bryce hung up on the last call, a depressing sense of calamity, unsettlingly anti-climatic, began to press down on him. Pierce was talking about plans for the next week with an enthusiasm which should have been completely contagious. ”

“ Man has reached space—do you think he'll ever go back to the ground? In space he has gravity only when he wants it, and any weight of gravity he likes, depending on how fast he spins his house. And no gravity when he wants that. ”

“ Bryce had needed to say nothing the whole time except “Right. That's it,” and everything went as he wanted it.
“A perfect left hand man,” he smiled, stretching, and turned the polarization dial to let in the sunlight.
The telephone rang. He picked it up and the desk clerk said in a deferentially hushed voice, “Eight o'clock, Mister Carter.”
For some reason the hushed voice struck him as funny. “Thanks, I'm up.” He hung up and stretched again. It was soothing to have someone solicitous that he arose on time, if only a hotel. The hotel had given him a lot of good service. ”

“ You see what that means to engineers in the advantage of building things? No weight in transportation, no weight in travel, limitless speed and almost no cost as long as he stays away from planet pulls. ”

“ It was a new drug, he said, found being used by a tribe in Central Africa. “I've heard of it for some time and what you mentioned a little while back reminded me of it.”
Bryce caught the hidden reference. Central Africa—and the Manoba group. So Pierce had not dismissed the mind hunter from his thoughts as a problem to be easily dealt with.
“It's still in the testing stage,” Pierce added. “But some of it is circulating among medical students. The tests have interesting effects. And, as I say, tonight's a good night to experiment, it's called B'nyab i'io.” ”

“ I'll keep making calls until they break in on me and cut this line.
“Meanwhile, spread the word. Break connections with me and the whole organization. Get out of range before the trap closes. But pass on this warning first.
“I'll hold out against questioning a short time. The police will get me eventually, of course. And when they do they'll pump me dry. They'll get names and addresses. The whole works will get grabbed, unless you move fast. Spread the word.”
Bryce paused and winked at Pierce who was standing at his elbow, “Any questions? Yes, I'm sure. Of course I'm sure. Any other questions? ”
