"You bet. They couldn't pilot a ship without them."

"And you understand all that?"

"Not all that. I wish I did. I hope I understand enough. We'll have to Jump to Lingane, you know."

"Is that hard to do?"

"No, not if you know the figures, which are all here, and have the controls, which are all there, and if you have experience, which I haven't. For instance, it should be done in several Jumps, but I'm going to try it in one because there'll be less chance of trouble, even though it means a wasteful use of energy."

He shouldn't tell her; there was no point ill telling her; it would be cowardly to frighten her; and she'd be hard to handle if she got really frightened, panicky frightened. He kept telling himself all that and it did no good. He wanted to share it with somebody. He wanted part of it off his own mind.

He said, "There are some things I should know that I don't. Things like the mass density between here and Lingane affect the course of the Jump, because that mass density is what controls the curvature of this part of the universe. The Ephemeris-that's this big book here-mentions the curvature corrections that must be made in certain standard Jumps, and from those you're supposed to be able to calculate your own particular corrections. But then if you happen to have a super giant within ten light-years, all bets are off. I'm not even sure if I used the computer correctly."

"But what would happen if you were wrong?"

"We could re-enter space too close to Lingane's sun."

She considered that, then said, "You have no idea how much better I feel."

"After what I've just said?"

"Of course. In my bunk I simply felt helpless and lost with so much emptiness in all directions. Now I know that we're going somewhere and that the emptiness is under our control."

Biron was pleased. How different she was. "I don't know about it's being under our control."

She stopped him. "It is. I know you can handle the ship."

And Biron decided that maybe he could at that.

Artemisia had tucked her long unclad legs under her and sat facing him. She had only her filmy underclothes for cover, but seemed unconscious of the fact, though Biron was definitely not.

She said, "You know, I had an awfully queer sensation in the bunk, almost as I were floating. That was one of the things that frightened me. Every time I'd turn, I'd give a queer little jump into the air and then flop back slowly as if there were springs in the air holding me back."

"You weren't sleeping in a top bunk, were you?"

"Yes, I was. The bottom ones give me claustrophobia, with another mattress six inches over your head."

Biron laughed. "Then that explains it. The ship's gravitational force is directed toward its base, and falls off as we move away from it. In the top bunk you were probably twenty or thirty pounds lighter than on the floor. Were you ever on a passenger liner? A really big one?"

"Once. When Father and I visited Tyrann last year."

"Well, on the liners they have the gravitation in all parts of the ship directed toward the outer hull, so that the long axis of the ship is always 'up,' no matter where you are. That's why the motors of one of those big babies are always lined up in a cylinder running right along the long axis. No gravity there."

"It must take an awful lot of power to keep an artificial gravity going."

"Enough to power a small town."

"There isn't any danger of our running short of fuel, is there?"

"Don't worry about that. Ships are fueled by the total conversion of mass to energy. Fuel is the last thing we'll run out of. The outer hull will wear away first."

She was facing him. He noted that her face had been cleaned of its make-up and wondered how that had been done; probably with a handkerchief and as little of the drinking water as she could manage. She didn't suffer as a result, for her clear white skin was the more startlingly perfect against the black of her hair and eyes. Her eyes were very warm, thought Biron.

The silence had lasted a little too long. He said hurriedly, "You don't travel very much, do you? I mean, you were on a liner only once?"

She nodded. "Once too often. If we hadn't gone to Tyrann, that filthy chamberlain wouldn't have seen me and-I don't want to talk about that."

Biron let it. go. He said, "Is that usual? I mean, not traveling."

"I'm afraid so. Father is always hopping around on state visits, opening agricultural expositions, dedicating buildings. He usually just makes some speech that Aratap writes for him. As for the rest of us, however, the more we stay in the Palace, the better the Tyranni like it. Poor Gillbret! The one and only time he left Rhodia was to attend the Khan's coronation as Father's representative. They've never let him get into a ship again."

Her eyes were downcast and, absently, she pleated the material of Biron's sleeve where it ended at the wrist. She said, "Biron."

"Yes-Arta?" He stumbled a bit, but it came out.

"Do you think Uncle Oil's story can be true?"

"Do you suppose it could be his imagination? He's been brooding about the Tyranni for years, and he's never been able to do anything, of course, except to rig up spy beams, which is only childish, and he knows it. He may have built himself a daydream and, over the years, gradually come to believe in it. I know him, you see."

"Could be, but let's follow it up a little. We can travel to Lingane, anyway."

They were closer to one another. He could have reached out and touched her, held her in his arms, kissed her.

And he did so.

It was a complete non sequitur. Nothing, it seemed to Biron, had led to it. One moment they were discussing Jumps and gravity and Gillbret, and the next she was soft and silky in his arms and soft silky on his lips.

His first impulse was to say he was sorry, to go through all the silly motions of apology, but when he drew away and would have spoken, she still made no attempt at escape but rested her head in the crook of his left arm. Her eyes remained closed.

So he said nothing at all but kissed her again, slowly and thoroughly. It was the best thing he could have done, and at the time he knew it.

Finally she said, a bit dreamily, "Aren't you hungry? I'll bring you some of the concentrate and warm it for you. Then, if you want to sleep, I can keep an eye on things for you. And-and I'd better put on more of my clothes."

She turned as she was about to go out the door. "The food concentrate tastes very nice after you get used to it. Thank you for getting it."

Somehow that, rather than the kisses, was the treaty of peace between them.

When Gillbret entered the control room, hours later, he showed no surprise at finding Biron and Artemisia lost in a foolish kind of conversation. He made no remarks about the fact that Biron's arm was about his niece's waist.

He said, "When are we Jumping, Biron?"

"In half an hour," said Biron.

The half hour passed; the controls were set; conversation languished and died.

At zero time Biron drew a deep breath and yanked a lever the full length of its arc, from left to right.

It was not as it had been on the liner. The Remorseless was smaller and the Jump was consequently less smooth. Biron staggered, and for a split second things wavered.

And then they were smooth and solid again.

The stars in the visiplate had changed. Biron rotated the ship, so that the star field lifted, each star moving in a stately arc. One star appeared finally, brilliantly white and more than a point. It was a tiny sphere, a burning speck of sand. Biron caught it, steadied the ship before it was lost again, and turned the telescope upon it, throwing in the spectroscopic attachment.

He turned again to the Ephemeris, and checked under the column headed "Spectral Characteristics." Then he got out of the pilot's chair and said, "It's still too far. I'll have to nudge up to it. But, anyway, that's Lingane right ahead."
