"Might have absorbed them," Issib corrected.

"However it happened," said Shedemei, "where the moderns went, there were no more robusts, heidelbergs, or erects. So why do both angels and diggers survive?"

"Because they don't compete for resources?" asked Chveya.

"My good student," said Shedemei with a smile. "But the diggers do eat the angels' young. And worship the statues they make. So it's not the same as, for instance, octopuses and eagles, which simply don't compete in any way. The angels are prey to the diggers. And yet they survive."

"Art lovers," said Nafai.

It sounded like another wisecrack and Luet was ready to poke him, but Shedemei answered as if it were a serious suggestion. "I think you're right, Nafai. I think there's something biological here, and the sculptures are involved. Didn't you say, Oykib, that you've learned that the statues are always associated with mating and breeding in their worship?"

Oykib blushed and looked furtively at his wife, then at Nafai.

"Don't be shy about it, Okya," said Volemak. "Nafai felt it was wise to tell the rest of us about what you can do. Not everybody-just the people in this room. No reason to make everybody else paranoid about their prayers."

Issib grinned maliciously. "We, of course, are the ones who are so perfect of heart that we don't mind being spied on."

"What Issya is trying to say," said Volemak, "is that we accept that some of us have the ability to learn things that others might wish kept secret. But you've shown such remarkable discretion throughout your childhood and on into adulthood that we aren't afraid of you."

"I am," said Chveya. "That's the only reason I let you get me pregnant."

"Veya," Luet remonstrated. Did the girl have to be so crude?

"Anyway, Oykib, is that right?" said Shedemei.

"Yes," he said. "Some of the ... worshipful thoughts... they're downright pornographic. I mean, the way they think of the statues. We've seen how most of them were worn down until some of them were just lumps. They worship by rubbing the statues all over themselves,"

"That's very helpful," said Shedemei. "That's not a behavior I've seen in rats or any other rodent. Have you ever seen anything about that in your studies?"

"You're the biologist, Shedya," said Hushidh. "If you haven't seen it, you can count on it that we haven't."

"As long as we're on the subject of who knows what," said Luet, "I'd like to know why I'm here. I mean, Shedya's husband isn't here, and Aunt Rasa isn't here, so we're not doing this in couples cm- anything. Shuya and Veya are both needed for understanding the diggers and angels because they can see things that language can't convey. Oykib's method is different, but the result is the same. Nafai is the oik with the cloak, who has his face on a sculpture down in the digger city. Issib can't work in the fields and he's good at language and nobody handles the Index better than he does, so he'll be vital for research and conversation. Why am I here?"

"Feeling a little insecure, my love?" asked Nafai with mock solicitude.

"You're here," said Volemak, "because you're you. Not everybody has to have a specialization for what I have in mind. And you communicate with the Oversoul better than anyone."

"Not when you use the Index," said Luet. "I shouldn't be here."

"Shut up, Lutya," said Hushidh cheerfully. "Your self-doubt is wasting everyone's time."

"Be patient," said Volemak. "I'm making my point, and you'll understand." He took Shedemei's illustrations off the display and replaced them with a map of the immediate area. "Here we are," he said, "and here are the diggers. And way up here are the angels. Take a wild guess which culture we'll come to understand best."

"Especially if they get into a kidnapping mood again," said Issib.

"I think that this can lead to an unfortunate outcome," said Volemak. "First, we'd no doubt become closer to the species we know the best, and that might be a serious mistake. Second, and perhaps more important, the angels would certainly assume that we were closer to the diggers, and therefore they would be suspicious of everything we did. Perhaps hostile. You see the problem?"

Issib nodded. "You want some of them to go up and live among the angels."

"That sounds so final," said Nafai. This time Luet did poke him.

"Not some of them, Issya," said Volemak. "Some of you"

Issib looked angry. "Not me," he said. "Not the chair."

Luet understood. He had hated those years in the wilderness when he had been physically helpless except when in his floating chair. To have Hushidh have to lift him and carry him and help him with his bodily needs-it was bad enough when his children were little, but now it would be an unbearable humiliation. Here in the vicinity of the ship his magnetic floats worked just as they had in the city of Basilica, giving him nearly normal physical freedom. He was not about to give that up.

"Hear me out," said Volemak. "I've thought this through very carefully, and if you Ksten reasonably you'll agree with my conclusions. First, I don't think we should send very many to the angels, because we need most of our strength here, working the fields and establishing the colony. So I'm sending only two couples and their small children. I can't send Shedemei, because she has to be here, using the instruments in the ship. But I need to send somebody who is as methodical as she is, and as familiar with the library. That points to you, Issib."

"It points to anybody here and half the people not here," said Issib.

"Chveya and Hushidh both have roughly the same ability," said Volemak, "and that ability is indispensable. So one stays here, and one goes there."

"Oykib is the most valuable one for learning languages," said Issib. "Send him up there."

"I need Oykib down here," said Volemak. "I want him learning the digger language alongside Elemak."

Luet understood, as she was sure everyone else did-it would not be healthy if Elemak were the only interpreter they had. Volemak didn't want to say it outright, but Elemak could not be wholly trusted. And the way he'd been acting since the night of the kidnapping, he might not accept the assignment to work with the diggers anyway.

"Besides," said Volemak, "the diggers know Oykib."

"They know Nafai, too," said Issib.

"Don't fight me on this, Issya," said Volemak. "Nafai they see as a god. Therefore it's very important that they not see too much of him. Let them worship the clay head and leave the man himself a mystery."

"In other words," said Nafai, "nobody who knows me could worship me."

"That's pretty much it," said Volemak.

"I worship you," Luet said, too sweetly.

Nafai smiled sweetly back.

"As for your loathing for the chair," said Volemak, "Nafai and I are pretty sure we can install a relay somewhere on that peak. It overlooks the angels' valley as well as the whole canyon approach. I think your magnetics will work there."

"Unless I walk behind a tree," said Issib.

"The relay consists of four installations so that there's always a parallax," said Nafai. "It would have to be a very big tree."

"If the magnetics work, I'll do it," said Issib.

"You'll do it anyway," said Volemak. "You'll just be angrier if you're in the chair. But think of this as the consolation prize. You get the Index."

"So there we'll be," said Nafai. "The four of us. The brothers who married the sisters."

"I'll still be useless," said Luet, trying to sound dispassionate, but failing.

"No more so than Nafai," said Volemak. "And no less. The angels aren't going to be as impressed by the glowing skin as the diggers were. Their first exposure to us was an act of wanton violence. Even with Hushidh and Issib to counsel you, it's going to take some delicate maneuvering to get them to accept you in the first place. Yasai and Padarok have assured me that our injured angel made no offer of violence. But that doesn't mean that the others are necessarily peaceable. After all, they are a sentient species. If humans and diggers are any example of what that means, we can anticipate that they have just as many murderous tendencies as we have."
