"What's that?"

"Once every fifteen minutes, the computer tallies the animals in all categories," Arnold said. "Like this."

"What you see here," Arnold said, "is an entirely separate counting procedure. It isn't based on the tracking data. It's a fresh look. The whole idea is that the computer can't make a mistake, because it compares two different ways of gathering the data. If an animal were missing, we'd know it within five minutes."

"I see," Malcolm said. "And has that ever actually been tested?"

"Well, in a way," Arnold said. "We've had a few animals die. An othniellan got caught in the branches of a tree and strangled. One of the stegos died of that intestinal illness that keeps bothering them. One of the hypsilophodonts fell and broke his neck. And in each case, once the animal stopped moving, the numbers stopped tallying and the computer signaled an alert."

"Within five minutes."

"Yes."

Grant said, "What is the right-hand column?"

"Release version of the animals. The most recent are version 4.1 or 4.3. We're considering going to version 4.4."

"Version numbers? You mean like software? New releases?"

"Well, yes," Arnold said. "It is like software, in a way. As we discover the glitches in the DNA, Dr. Wu's labs have to make a new version."

The idea of living creatures being numbered like software, being subject to updates and revisions, troubled Grant. He could not exactly say why-it was too new a thought-out he was instinctively uneasy about it. They were, after all, living creatures…

Arnold must have noticed his expression, because he said, "Look, Dr. Grant, there's no point getting starry-eyed about these animals. It's important for everyone to remember that these animals are created. Created by man. Sometimes there are bugs. So, as we discover the bugs, Dr. Wu's labs have to make a new version. And we need to keep track of what version we have out there."

"Yes, yes, of course you do," Malcolm said impatiently. "But, going back to the matter of counting-I take it all the counts are based on motion sensors?"

"Yes."

"And these sensors are everywhere in the park?"

"They cover ninety-two percent of the land area," Arnold said. "There are only a few places we can't use them. For example, we can't use them on the jungle river, because the movement of the water and the convection rising from the surface screws up the sensors. But we have them nearly everywhere else. And if the computer tracks an animal into an unsensed zone, it'll remember, and look for the animal to come out again. And if it doesn't, it gives us an alarm."

"Now, then," Malcolm said. "You show forty-nine procompsognatbids. Suppose I suspect that some of them aren't really the correct species. How would you show me that I'm wrong?"

"Two ways," Arnold said. "First of all, I can track individual movements against the other presumed compys. Compys are social animals, they move in a group. We have two compy groups in the park. So the individuals should be within either group A or group B."

"Yes, but-"

"The other way is direct visual," he said. He punched buttons and one of the monitors began to flick rapidly through images of compys, numbered from 1 to 49.

"These pictures are…"

"Current ID images. From within the last five minutes."

"So you can see all the animals, if you want to?"

"Yes. I can visually review all the animals whenever I want."

"How about physical containment?" Gennaro said. "Can they get out of their enclosures?"

"Absolutely not," Arnold said. "These are expensive animals, Mr. Gennaro. We take very good care of them. We maintain multiple barriers. First, the moats." He pressed a button, and the board lit up with a network of orange bars. "These moats are never less than twelve feet deep, and water-filled. For bigger animals the moats may be thirty feet deep. Next, the electrified fences." Lines of bright red glowed on the board. "We have fifty miles of twelve-foot-high fencing, including twenty-two miles around the perimeter of the island. All the park fences carry ten thousand volts. The animals quickly learn not to go near them."

"But if one did get out?" Gennaro said.

Arnold snorted, and stubbed out his cigarette.

"Just hypothetically," Gennaro said. "Supposing it happened?"

Muldoon cleared his throat. "We'd go out and get the animal back," he said "We have lots of ways to do that-taser shock guns, electrified nets, tranquilizers. All nonlethal, because, as Mr. Arnold says, these are expensive animals."

Gennaro nodded. "And if one got off the island?"

"It'd die in less than twenty-four hours," Arnold said. "These are genetically engineered animals. They're unable to survive in the real world."

"How about this control system itself?" Gennaro said. "Could anybody tamper with it?"

Arnold was shaking his head. "The system is hardened. The computer is independent in every way. Independent power and independent backup power. The system does not communicate with the outside, so it cannot be influenced remotely by modem. The computer system is secure."

There was a pause. Arnold puffed his cigarette. "Hell of a system," he said. "Hell of a goddamned system."

"Then I guess," Malcolm said, "your system works so well, you don't have any problems."

"We've got endless problems here," Arnold said, raising an eyebrow. "But none of the things you worry about. I gather you're worried that the animals will escape, and will get to the mainland and raise hell. We haven't got any concern about that at all. We see these animals as fragile and delicate. They've been brought back after sixty-five million years to a world that's very different from the one they left, the one they were adapted to. We have a hell of a time caring for them.

"You have to realize," Arnold continued, "that men have been keeping mammals and reptiles in zoos for hundreds of years. So we know a lot about how to take care of an elephant or a croc. But nobody has ever tried to take care of a dinosaur before. They are new animals. And we just don't know. Diseases in our animals are the biggest concern."

"Diseases?" Gennaro said, suddenly alarmed. "Is there any way that a visitor could get sick?"

Arnold snorted again. "You ever catch a cold from a zoo alligator, Mr. Gennaro? Zoos don't worry about that. Neither do we. What we do worry about is the animals dying from their own illnesses, or infecting other animals. But we have programs to monitor that, too. You want to see the big rex's health file? His vaccination record? His dental record? That's something-you ought to see the vets scrubbing those big fangs so he doesn't get tooth decay.

"Not just now," Gennaro said. "What about your mechanical systems?"

"You mean the rides?" Arnold said.

Grant looked up sharply: rides?

"None of the rides are running yet," Arnold was saying. "We have the jungle River Ride, where the boats follow tracks underwater, and we have the Aviary Lodge Ride, but none of it's operational yet. The park'll open with the basic dinosaur tour-the one that you're about to take in a few minutes. The other rides will come on line six, twelve months after that."

"Wait a minute," Grant said. "You're going to have rides? Like an amusement park?"

Arnold said, "This is a zoological park. We have tours of different areas, and we call them rides. That's all."

Grant frowned. Again he felt troubled. He didn't like the idea of dinosaurs being used for an amusement park.

Malcolm continued his questions. "You can run the whole park from this control room?"

"Yes," Arnold said. "I can run it single-handed, if I have to. We've got that much automation built in. The computer by itself can track the animals, feed them, and fill their water troughs for forty-eight hours without supervision."

"This is the system Mr. Nedry designed?" Malcolm asked. Dennis Nedry was sitting at a terminal in the far corner of the room, eating a candy bar and typing.

"Yes, that's right," Nedry said, not looking up from the keyboard.

"It's a hell of a system," Arnold said proudly.

"That's right," Nedry said absently. "Just one or two minor bugs to fix."

"Now," Arnold said, "I see the tour is starting, so unless you have other questions…"

"Actually, just one," Malcolm said. "Just a research question. You showed us that you can track the procompsognathids and you can visually display them individually. Can you do any studies of them as a group? Measure them, or whatever? If I wanted to know height or weight, or…"

Arnold was punching buttons. Another screen came up.

"We can do all of that, and very quickly," Arnold said. "The computer takes measurement data in the course of reading the video screens, so it is translatable at once. You see here we have a normal Poisson distribution for the animal population. It shows that most of the animals cluster around an average central value, and a few are either larger or smaller than the average, at the tails of the curve."

"You'd expect that kind of graph," Malcolm said.

"Yes. Any healthy biological population shows this kind of distribution. Now, then," Arnold said, lighting another cigarette, "are there any other questions?"

"No," Malcolm said. "I've learned what I need to know."

As they were walking out, Gennaro said, "It looks like a pretty good system to me. I don't see how any animals could get off this island,"
