uniform continuum of pressure values from a minimum to a maximum.

It was like—well, like having an air pressure in a car tire that wasn't thirty pounds or thirty-two pounds, but every value from zero to thirty-five pounds.

It was like transforming the points and intervals on a line to a domain where there had previously been only points!

Hugh Dunnam was waiting for him when he arrived in the pilot room. His iron grey hair was mussed from exasperated hair-pulling. He jabbed a finger in the direction of the automatic pilot without speaking.

Ren saw that it had been cut out. The first mate was controlling the ship manually. The robot mechanism was still turning out its data sheets, however. In five minutes Ren saw that the only consistent detail was the distance of the ship from the planet.

Commander Dunnam watched him silently for several minutes. Finally Ren laid down the data sheets and looked at him with a slow smile.

"Well?" Dunnam asked.

"It reminds me of a kid I knew quite well when I was in grade school," Ren said. "He was an incurable liar, so you could never take anything he said, but always had to figure out the truth yourself and act on it regardless of what he might claim to be the truth."

"You mean the instruments have all become liars?" Hugh Dunnam asked, amazed at the idea.

"No," Ren replied. "I don't think that. I think nature is the liar, in a way. I mean she is according to our standards. We'll have to outguess her, that's all."

"Now you're cooking," Hugh exclaimed. "What would you suggest?"

"We know this planet has gravity," Ren replied. "There's no way of knowing how much or how little. Suppose we kill our tangential speed and just fall in? The gravity will take care of that, regardless of its value or set of values."

"But we'll crash!" Hugh objected.

Ren took one of the report sheets and figured rapidly on its back.

"Unless I'm radically wrong," he said, "our speed of impact will be every speed from zero to a thousand miles a minute. Not only that, no matter how we try to land that will be the set of values for our speed. Naturally the thousand miles a minute will smash us flat, but the zero speed will let us down easy."

"And so?" Hugh asked suspiciously.

"No matter how we go in," Ren smiled, "we'll smash the ship and kill everybody—and we'll land safely."

"Are you crazy?" Hugh snorted.

"I—I'm not quite sure," Ren said seriously. "I think that we've run across a bit of matter that works from different basics than what we are used to. You might call it a different metaphysics. That's what it really amounts to."

A pain of remembrance appeared on his face.

"That's why I didn't get my degree," he said softly. "I insisted that it might be possible there were no absolute rules underlying all reality, but only relative rules that might be changeable. In other words, I questioned the validity of asserting that natural law was universal. They flunked me in stability."

"Yes, I know," Commander Dunnam said sympathetically. "One of the most unjust rules of modern education in the opinion of many, but no way of changing it unless the educators themselves did it. Since they all passed O.K. in stability, they think everyone else should. Maybe they're afraid they would be considered unstable if they wanted to make such a major change."

Ren glanced toward the screen that showed the magnified image of the interstellar wanderer, and back again to the commander.

"Of course," he said, "I'm trying to use ordinary basics transposed onto the basics of this system, which is wrong. Or it may be right. It might be better if we just turned around and went back. There's no way of knowing ahead of time whether we'd be killed on landing or not."

"Look, Ren," the commander said seriously. "I like you. You—you're just about like my son would have been today if he had lived. I'm just a spaceman. I depend on instruments. They don't work here. All of us are just as helpless as if we didn't know the first thing about our trade. We can't go back without landing on this stray planet. If we tried to tell them the reasons, I'd be retired and the whole crew would be stuck on various routine tub runs. Suppose you unofficially take charge. If we get killed—we all expect to end that way in our trade. If we don't, we'll be able to take back something with us to prove what we've run into. Maybe it will vindicate you and make you a reputation. You'll get all the credit I can turn your way."

"Thank you, sir," Ren said, his voice choked with gratitude. In his heart he knew that he would have sold his soul to the devil for this coming experience that had been given him without his asking.

He had spent years preparing for this—years that his teachers had felt were wasted. He had explored all the crazy systems of logic abandoned in the march of progress. He had even devised systems of his own, synthesized from undefined symbols according to strange patterns outside the field of logic.

Yes. He felt that even if the basics of natural law in operation here were purely nonsense laws, he would be able to penetrate to a rational manipulation and control of things. Perhaps he might even set up the pattern operating, and join it in some way with so-called normal science.

Commander Dunnam came to attention, a twinkle in his eyes.

"At your command, sir," he said, saluting.

"Not that," Ren objected. "Let me just play the part of a scientist under your command, whose part it is to advise only."

"No," Hugh Dunnam said. "Until we leave this part of space you're in sole command. Call it what you want—a hunch maybe; but I feel that there is a purpose in things, and it wasn't chance that gave you the type of mind you have and threw you under my command on this trip."

"Very well, sir," Ren said, returning the salute. He smiled. Behind his smile his analytical mind was working rapidly.

"The commander's reactions are not normal," his thoughts said. "They could not be dictated by anything in his past. Therefore they are dictated by something outside him—something on that planet below!"

It was a wild conjecture. The more he thought of it the more certain Ren became that there was some intelligence down there that had already made contact with the minds in the ship.

Strangely, this didn't alarm him. He felt that "it" was friendly. He felt that "it" had plumbed the minds of all on board and chosen him to take over and lead the others.

Eagerly he "listened," but no faintest whisper or flavor of thought came to support his feeling of an alien contact. In spite of this he went ahead with his study of things with a confidence that "something" was watching and would see them through all right.

His eyes turned again to the image of the cold planet below. That image returned his stare blankly, its inscrutable surface devoid of any hint of mystery.

"I'd suggest we keep circling the planet until I have a chance to form a few definite conclusions," Ren said. "If that can't be done I'd suggest we retreat far enough so we can."

"Yes sir," Commander Dunnam said quietly. He repeated the suggestion in the form of an order to the first mate.

Ren studied the image of the planet. He left the pilot room and wandered over the ship aimlessly. He talked to the members of the crew he ran into.

He slept at his usual time. He ate his meals as usual. He stopped talking to the crew and just wandered about, occasionally going to the pilot room and studying the strange sphere of matter.

After three days he ordered the ship dropped to an orbit about five thousand miles from the surface. Almost as soon as the ship reached its new orbit changes began to be noticed.

Ren had the commander issue an order that every crew member was to report all unusual happenings within the ship.
