and eventually—destroy it! Destroy it and fashion another! Maclure, medicine has done all for me that it can. I am the final example of the surgical art. Once my brain was transplanted into a youthful body, but even I could not stand the shock. I died, and was revived only with the greatest difficulty.
"Three times since then I have died. The last time it took three hours to revive me. Ten minutes more and I would never have lived again. Under the laws of nature I can last no longer. And so you must come to my rescue."
"How am I to do that?" demanded Angel.
"For me," breathed Mr. Sapphire, "you will suspend these laws. Do not interrupt. I can give you only a few minutes more before I retire for a treatment.
"All creation is in motion, we know. So we are taught. Earth moves about the sun, sun about the great hub of the galaxy, the galaxy in a mighty circle about its own directrix—space itself, 'ether,' so called, is like a mighty ball rolling and tumbling through unimaginable chaos. To this outside of space we cannot attain, for to go to the end of space is to return to the starting point.
"But there is another locus in space—wholly unique, wholly at variance with any other time-and-space sector that may be marked off. Can you conceive of it?"

"That is it. You will work for me?"
"Damn right I will," exploded Angel. "And not for your money or anything you have to offer—but just for the kick of finding your quiet spot and doping it out!"
"That," whispered Mr. Sapphire, "is how I had estimated it." The wall began to slide back into place again, hiding his shriveled body and tangle of machinery, when he spoke again: "Use the metal tab lying on that table." He was gone.
Angel looked about, and as a table lit up with a little flash, he picked a tag of some shiny stuff from it and pocketed the thing. He heard the ponderous door grind open behind him.
Chapter II
Angel, his mind buzzing with figures and colossal statistics, had aimlessly wandered into the proving room. Assistants leaped to attention, for he was known as a captain in the Tri-Planet Guard. And the ship and plotting were, of course, official business. That was only one of the many ways in which his work had been made easier. But work it still was—the hardest, most gruelling kind of work of which any man could be capable. The first job he had ordered had been the construction of immense calculating machines of a wholly novel type. He could not waste his own
