If she could do that to Obrenova, why not to Firebrass? Then she would be the captain.

The images evoked were pleasing, but she could not do that to anyone, no matter how strongly she felt. To violate their human rights and dignities would be to violate, to destroy herself.

During the week that followed she sometimes beat her fists on the table or wept. Or both. The next week she told herself that she was being immature. Accept what was unavoidable and enjoy what was left. Was it so important that she should finally be captain of an airship?

To her, yes. To anyone else in the world, no.

So she swallowed her resentment and disgust.

Piscator must have known how she felt. Frequently, she caught him looking at her. He would smile or else just look away. But he knew, he knew!

Six months passed. Firebrass gave up trying to get Obrenova to move into his apartment. He made no secret of his desire nor did he hide the fact that she had finally rejected him.

''You win some, you lose some," he said to Jill with a wry smile. "Maybe she doesn't go for men. I know a score or more who've been panting for her, and she's as cool to them as if she were the Venus de Milo."

"I'm sure she isn't a lesbian," Jill said.

"Takes one to know one, heh? Haw, haw!"

"Damn it, you know I'm ambivalent," she said angrily, and she walked away.

"Indecisive is the right word!" he had shouted after her.

At that time Jill was living with Abel Park, a tall, muscular, handsome, and intelligent man. He was a Rivertad, one of the many millions of children who had died on Earth after the age of five. Abel did not remember what country he had been born in or what his native language had been. Though resurrected in an area the majori­ty of whom were medieval Hindus, he had been adopted and raised by a Scots couple. These were eighteenth-century Lowlanders of peasant origin. Despite his poverty, the foster father had managed to become a medical doctor in Edinburgh.

Abel had left his area after his parents had been killed and had wandered down-River until he came to Parolando. Jill had liked him very much and had asked him to be her hutmate. The big fellow had gladly moved in, and they had had some idyllic months. But, though he was intelligent, he was ignorant. Jill taught him every­thing she could; history, philosophy, poetry, and even some arith­metic. He was eager to learn, but eventually he accused her of patronizing him.

Shocked, Jill had denied this.

"Ijust want to educate you, to give you knowledge denied you because you died so early."

"Yes, but you get so impatient. You keep forgetting that I don't have your background. Things which seem simple to you, because you were raised among them, are bewildering to me. I don't have your referents."

He had paused, then said, "You're a knowledge-chauvinist. In short, a... what's the word? ... a snob."

Jill was even more shocked. She denied this, too, though reflec­tion showed her that he was perhaps right. By then it was too late to make reparations. He had left her for another woman.

She consoled herself by telling herself that he was too used to the idea of the man being the boss. He found it difficult to accept her as an equal.

Later, she realized that that was only partly true. Actually, she had, deep down, a contempt for him because he was not, and never would be, her mental equal. That had been an unconscious attitude, and now that she was aware of it, she regretted having it. In fact, she felt ashamed of it.

After that, she made no effort to have anything but the most impermanent liaisons. Her partners were men and women who, like her, wanted only sexual satisfaction. Usually, she and they got it, but she always felt frustrated afterward. She needed a genuine affection and companionship.

Obrenova and Thorn, she observed, must be doing the same thing as she. At least, no one moved into their huts. For that matter, though, she never observed them taking any interest in anybody which could be interpreted as sexual. As far as she knew, they were not even having one-night stands.

Thorn did, however, seem to like Obrenova's company. Jill often saw them talking earnestly together. Perhaps Thorn was trying to get her to be his lover. And perhaps the Russian refused because she thought she would only be a substitute for his first wife.

Three days before the final liftoff, a holiday was declared. Jill left the plains area because it was so crowded and noisy with people from up and down The River. She estimated that there were already several hundred thousands camping in Parolando and that there would be over twice that number by the time the Parseval left. She retired to her hut, leaving it only for a little fishing. The second day, as she was sitting on the edge of the little lake, looking emptily into the water, she heard someone approaching.

Her irritation at the invasion died when she saw Piscator. He was carrying a fishing pole and a wickerwork basket. Silently, he sat down beside her and offered her a cigarette. She shook her head. For some time they stared at the surface, rippled by the wind, broken now and then by a leaping fish.

Finally, he said, "It won't be long before I must reluctantly say goodbye to my disciples and to my piscatorial pursuits."

"Is it worth it to you?"

"You mean, giving up this pleasant life for an expedition that may end in death? I won't know until it happens, will I?"

After another silence, he said, "How have you been? Any more experiences such as that night?"

"No, I'm fine." "But you have been carrying a knife in your heart.''

"What do you mean?" she said, turning her head to look at him. She hoped her puzzlement did not look as faked as it felt to her.

''I should have said three knives. The captaincy, the Russian, and most of all, yourself."

"Yes, I have problems. Don't we all? Or are you an exception? Are you even human?"

He smiled and said, "Very much so. More than most, I can say with seeming immodesty. Why is that? Because I have realized my human potentiality almost to its fullest. I can't expect you to credit that. Nor will you, unless, some day ... but that day may never come.

"However, regarding your question of my humanity. I have sometimes wondered if some people we have met are human. I mean, do they belong to Homo sapiens?

"Isn't it possible, even highly probable, that the Whoevers responsible for all this have agents among us? For what purpose, I don't know. But they could be catalysts to cause some kind of action among us. By action, I do not mean physical action, such as the building of the Riverboats and airships, though that may be part of it. I refer to psychic action. To a, shall we say, channeling of humanity? Toward what? Perhaps toward a goal somewhat similar to that which the Church of the Second Chance postulates. A spiritual goal, of refinement of the human spirit. Or perhaps, to use a Christian-Muslim metaphor, to separate the sheep from the goats."

He paused and drew on his cigarette.

"To continue the religious metaphor, there may be two forces at work here, one for evil, one for good. One is working against the fulfillment of that goal."

"What?" she said. Then, "Do you have any evidence for that?"

"No, only speculation. Don't get me wrong. I don't think that Shaitan, Lucifer if you will, is actually conducting a cold war against Allah, or God, whom we Sufis prefer to name The Real .But I sometimes wonder if there isn't a parallel to that in some sense ... well, it is all speculation. If there are agents, then they look like human beings."

"Do you know something I don't?"

"I have 'probably observed certain things. You have, too, the difference being that you have not put them into a pattern. A rather dark pattern it is. Though it is possible that I am looking at the wrong side of the pattern. If it were turned over, the other side might be blazing with light."
