The system, for all its faults, did have one positive effect, though: It kept the papers terse. The irony was that now, when the economics of scientific journals was irrelevant, the limits of his ability to memorize text imposed an equally strict need for economy.

When he was satisfied with the wording, he announced that he'd come up with the first section of the paper, and recited it aloud. The others abandoned their argument to consider it.

“That should be ‘field observations' rather than ‘observations in the field,'” Daljit said. “It's shorter.”

“Good thought. I'll change it.”

“Why ‘major dinosaur groups?'” Jamal asked. “Why not simply ‘dinosaurs?'”

“Because we don't know that
all
dinosaurs engage in the behavior. In fact, we're pretty certain that some—birds—don't.”

“Point taken.”

The phone rang.

“Yes?” Tamara said. “It's Gillian,” she told them. Then, to Gillian, “Leyster's working on the paper. Yes, already. Well, obviously he thought we had enough data. What? No! Well, it's about time. Hey, everybody! Lai-tsz's gone into labor!”

“She has?”

“You're kidding me.”

“Outstanding!”

“They're all happy and everybody sends their love. When did it start? Uh-huh. How's she doing? Well, of course.” She was silent for a bit, then said, “Okay, I'll ask him.”

She turned to Leyster. “Gillian wants to know if you're going to use Chuck's theory.”

The raft lurched. “Oh, cripes!” Daljit said. “Who's navigating?”

It took them over an hour to get the raft off the sand bar, and it was dirty and difficult work doing so. They all had to climb into the water (except Jamal, who stayed aboard and fretted) so the raft would ride higher in the water, and then wrangle it over toward deeper water.

Dirty and tired, and yet exhilarated by their eventual success, they shucked off their clothes and spread them out to dry. Daljit bullied them into raising poles at the rear and lashing a canvas to them to make a canopy to keep from getting sunburned.

They were amiably finishing up their comments on the opening of the paper—it was the simplest part, and there was the least room for disagreements of interpretation—when Tamara suddenly held a hand up and said, “Shhh!”

“What is it?” Leyster whispered.

She pointed to the left bank. A
Stygivenator molari
was walking briskly downriver along its margin, moving at a speed that kept it parallel to them. Every now and then it would glance over at them, its eyes bright and avaricious.

Leyster shivered involuntarily. A stygivenator was one of the larger predators, as large as a juvenile tyrannosaur but with the reflexes of an adult predator.

“What's it doing?” Jamal asked quietly.

“Pacing us,” Leyster whispered back. Fortunately, most theropods were lousy swimmers.

“So what should we do about that?”

“Keep quiet, and be very careful not to let the raft drift too close to it.”

Then the river bent, and they all had to frantically man the poles to keep the raft from running aground. The forest thickened at the bend, and the trees hung far out over the water, forcing the stygivenator inland. By the time they'd regained the center of the river, it was gone.

There were termite mounds on the right-hand side of the Eden—a metropolis of them. On the left, Leyster saw a marsh hopper prying open a freshwater clam with its tiny claws and furred paws. Suddenly a troodon that neither Leyster nor the marsh hopper had suspected was lurking there, snapped up the small mammal. It shook its head twice to snap the marsh hopper's spine, then lifted its neck and swallowed down the unfortunate animal whole.

While it was thus occupied, the stygivenator emerged from the wood, moving at top speed. Its jaws closed upon the troodon before the smaller predator knew what was happening. One crunch, and the bugger was dead.

It was an incredibly violent era, sustained only by the enormous number of offspring almost everything here produced. Which was what made it so astonishing that so many
did
reach adulthood. The network of interspecific cooperation—the tyrannosaur as farmer—resulted in a staggering efficiency, which allowed a greater population of the largest life forms than would otherwise be possible.

He couldn't help thinking again of Salley's talk, so long ago and so far in the future, when she had said that ceratopsians were farmed by their predators. He smiled. It was so typical of her to impress him with his own work. In some ways she was not a very good scientist: impatient with data, too ready to leap to conclusions, apt to judge an idea not by its merits but by its sheer niftiness.

But paleontology needed her, as leavening if nothing else. Science needed leapers as well as plodders, visionaries as well as detectives.

She was a kite. She needed only the most tenuous connection with the ground in order to fly, a sure string of logic with a reliable hand at the end of it to make sure she didn't take a nosedive straight into the ground. More than anything he wished he could be the hand at the end of her kite string.

Watching the banks flow by, he slid off into a reverie. He didn't notice when Jamal took the lead away from him, and moved to the bow to take readings. He didn't notice how careful the others were to avoid disturbing him.

The cycle began with the spring migrations, when flights of tyrannosaurs, living off their winter fat, spread across the land looking for territory to establish. These were the breeding males. The females followed at a more leisurely pace, sparing themselves the initial hardship, and arriving well-fed and ready to breed.

The Lord of the Valley (they could identify him by his scars) returned to claim the previous year's territory and, because he was experienced and in his prime, faced only a few challenges from younger males. He paced off the perimeter of his valley, singing, both to warn away competitors and to call in the titanosaurs.

The titanosaurs, those vast eating machines, drifted slowly through the valley, guided by its resident tyrannosaur toward the most productive areas. They stripped vast swaths of the upper-story vegetation, splintered trees, and enabled a bloom of understory vegetation. Now and then, the females deposited hundreds of eggs in a subsoil clutch before wandering away and forgetting about them entirely.

When the titanosaurs finally left, the understory was flourishing and the tyrannosaur was free at last to call in the herds of hadrosaurs and triceratopses.

Leyster held the whole in his mind now; he set about to boil it all down to the least number of words.

“Biocybernetic …” said Daljit. “
Is
there such a word?”

“There is now.”

“Does it mean anything?”

“Actually,” Jamal said, “The word
cybernetic
refers to feedback loops occurring not only in machines but also in and between living organisms. So there's really no need for the neologism.”

‘Leyster blushed. It had been a long time since he'd been caught out in a mistake of terminology. “I'll change it.”

“What I want to know,” Tamara said, “is why you don't mention the incident Katie and Nils saw. With the troodons.”

Katie and Nils had reported seeing a small flock of troodons actively drive some hadrosaurs away from a titanosaur nesting site. The savage little beasts, they reported, had rousted hadrosaurs ten times their size. They concluded that it had been done to protect the eggs.

“Its meaning is ambiguous,” Leyster said.

“Not to Katie and Nils.”

“Also, it only happened the once.”

“That anybody saw.”

Judiciously, Jamal said, “When you report the behavior, you say, ‘It is possible that …' Where's the problem?”

“I
hate
to include speculation in a scientific paper.”

There was a brief silence. “So,” Tamara said. “I guess that means you're not going to include Chuck's speculation?”

“I didn't say that. I haven't made up my mind yet.”

While Leyster thought about the paper and Daljit manned the sweep, Tamara trailed a fishing line, and caught a tiger-striped catfish. Jamal cleaned and gutted it, and they had sushi for dinner.

As they ate, they discussed the section of the paper which Leyster was working on. Here he got into more problematic behaviors.

The herds of hadrosaurs and triceratopses moved continually up and down the valley, feeding. Lai-tsz, whose ear for the sped-up recordings was better than the others', was able to establish that when the local vegetation was in danger of being overgrazed, the Lord or his Lady would seek out greener areas, and call the herds to them. Leyster had been skeptical of this at first, but then Lai-tsz had repeatedly demonstrated her ability to predict when the herds would disappear from established territory, and where they would go, based on the recordings. So he'd had to admit it was so.

He planned to cite this as an example of “ranching” behavior.

“Exactly what is the difference,” Daljit asked, “between domestication and ranching?”

“Domestication is the process whereby the predator species have rendered the prey species docile to their will.”

“Are you even sure they
are
domesticated?”

“Several times we've seen the Lord of the Valley approach a herd, of various species, singing. They huddle, with the young in the center. He walks around and around them. They turn to face him, cluster tighter, jostle each other. Tighter, closer, more assertive, until one individual gets expelled from the pack. Always the oldest, or weakest, or sickest. His Lordship surges forward, and—
snap!
—it's dead. Thirty minutes, start to finish.” Leyster grinned. “Beats hunting, doesn't it?”

“Okay, and ranching?”

“Ranching is the set of behaviors by which it cares for the herds—moving them between pastures, keeping away rival predators, and so on.”

“Well, you'll have to make sure that's spelled out clearly in the paper.”

“Teach your grandmother to suck eggs.”

They tied up for the night to a sandbar island overgrown by a snarl of young tanglewoods. Tamara waded ashore and chopped clear a section of the island to make a fire. She began to brew them some sassafras tea.

The phone rang.

“I'm not here,” Leyster said. “If anybody asks, I'm at a meeting and you don't know when I'll be back in the office.”

Daljit picked it up. She listened briefly, then put her hand over the receiver. “It's a
boy!
” she shouted.

Whoops and cheers.

Leyster took the phone. “So, does he look like anyone in particular?” he asked. Feeling a strange mixture of hope and apprehension.

“What does it matter?” Katie said. “We all love the little brat. You will too, as soon as you see him.”

“I know it doesn't matter, I'm just curious. Come on, you'd ask the same question yourself, if you weren't there.”

“Well … judging by the color of his skin, I'd have to say the father was either Jamal or Chuck.”

“The father is either Chuck or Jamal,” Leyster said, hand over the receiver.

“I'm a father?” Jamal said.


Maybe
a father,” Leyster said.

“You're half a father,” Daljit elaborated.

“I'm a fath!” Jamal said. “I'm a ther!”

He danced a clumsy little jig that made Daljit snap, “Watch the damn splint!” Tamra seized him, and kissed him deeply.

Leyster found that, for all he was happy for his friend, he felt a pang of jealousy as well. That could have been
his
son. The thought of what might have been stirred complex emotions within him.

The next morning, they cast off and headed downriver again. It was another beautiful day. Leyster felt alert and invigorated, and he had the paper pretty much whipped into shape by lunchtime.

Last of all, he composed the abstract:

Field observations reveal that major dinosaur groups in the late Maastrichtian communicated both intra- and interspecifically via infrasound. Communications between species are of particular note since they suggest cybernetic feedback loops operating within and helping to shape the ecosystem. Domestication and “ranching” behavior were observed. The advantages of this cooperative behavior to the predators are self-evident. Benefits to the prey species, though less obvious, are postulated to be equally compelling. It was a complex system working to the maximum benefit of all.

“I'm done,” he said.

Jamal applauded. “Well, let's hear it!”

“No, I should give the first full reading to everyone. That's only fair.”

Groans.

“You told us what you had yesterday,” Daljit pointed out.

“Yes, but yesterday we were nowhere near our destination. Today we're—how far is it we have yet to go?”

The mapping satellite was low in the sky, but they were just able to get a location from it. Daljit and Jamal huddled briefly over the maps, argued, then concluded that they'd reach the confluence of the Eden and Styx rivers sometime in early afternoon.

“Well, that settles it. With any kind of luck, we should be home by nightfall. We can have the inquisition then, with everybody present.” Leyster stood. “My turn at the sweep, I think.

Within the hour, the bioregion along the river was looking familiar. The land opened up. The towering forests retreated to the far distance, and the rich soil was overgrown with shrubs, ferns, and cycads, dotted with the occasional copse of hardwoods.

They were back in the farmlands.

It was this very familiarity, perhaps, which made them overly confident. Leyster was holding the raft steady in the gentle currents of the Eden, staring alertly ahead for shallow water, when Daljit said, “Uh-oh.”

They had seen the triceratopses from a distance, studding the landscape like huge, placid cattle. It was only when they got close that the number of them registered, and they were able to see how restless the creatures were.
