ut giving you a five…year mitment； and ten million dollars a year in funding。 Fifty million dollars； and no one tells you how to spend it。 You decide。 Everyone else just gets out of your way。〃
It sounded too good to be true。 Wu was silent for a long time。 Finally he said； 〃In return for what？〃
〃For taking a crack at the impossible；〃 Hammond said。 〃For trying something that probably can't be done。〃
〃What does it involve？〃
〃I can't give you details； but the general area involves cloning reptiles。〃
〃I don't think that's impossible；〃 Wu said。 〃Reptiles are easier than mammals。 Cloning's probably only ten； fifteen years off。 Assuming some fundamental advances。〃
〃I've got five years；〃 Hammond said。 〃And a lot of money； for somebody who wants to take a crack at it now。〃
〃Is my work publishable？〃
〃Eventually。〃
〃Not immediately？〃
〃But eventually publishable？〃 Wu asked； sticking on this point。
Hammond had laughed。 〃Don't worry。 If you succeed； the whole world will know about what you've done； I promise you。〃
And now it seemed the whole world would indeed know； Wu thought。 After five years of extraordinary effort； they were just a year away from opening the park to the public。 Of course； those years hadn't gone exactly as Hammond had promised。 Wu had had some people telling him what to do； and many times fearsome pressures were placed on him。 And the work itself had shifted…it wasn't even reptilian cloning； once they began to understand that dinosaurs were so similar to birds。 It was avian cloning； a very different proposition。 Much more difficult。 And for the last two years； Wu had been primarily an administrator； supervising teams of researchers and banks of puter…operated gene sequencers。 Administration wasn't the kind of work he relished。 It wasn't what he had bargained for。
Still； he had succeeded。 He had done what nobody really believed could be done； at least in so short a time。 And Henry Wu thought that he should have some rights； some say in what happened； by virtue of his expertise and his efforts。 Instead； he found his influence waning with each passing day。 The dinosaurs existed。 The procedures for obtaining them were worked out to the point of being routine。 The technologies were mature。 And John Hammond didn't need Henry Wu any more。
〃That should be fine；〃 Hammond said； speaking into the phone。 He listened for a while； and smiled at Wu。 〃Fine。 Yes。 Fine。〃 He hung up。 〃Where were we； Henry？〃
〃We were talking about phase two；〃 Wu said。
〃Oh yes。 We've gone over some of this before； Henry…〃
〃I know； but you don't realize…〃
〃Excuse me； Henry；〃 Hammond said； with an edge of impatience in his voice。 〃I do realize。 And I must tell you frankly； Henry。 I see no reason to improve upon reality。 Every change we've made in the genome has been forced on us by law or necessity。 We may make other changes in the future； to resist disease； or for other reasons。 But I don't think we should improve upon reality just because we think it's better that way。 We have real dinosaurs out there now。 That's what people want to see。 And that's what they should see。 That's our obligation； Henry。 That's honest； Henry。〃
And； smiling； Hammond opened the door for him to leave。
Control
Grant looked at all the puter monitors in the darkened control room； feeling irritable。 Grant didn't like puters。 He knew that this made him old…fashioned； dated as a researcher； but he didn't care。 Some of the kids who worked for him had a real feeling for puters； an intuition。 Grant never felt that。 He found puters to be alien； mystifying machines。 Even the fundamental distinction between an operating system and an application left him confused and disheartened； literally lost in a foreign geography he didn't begin to prehend。 But he noticed that Gennaro was perfectly fortable； and Malcolm seemed to be in his element； making little sniffing sounds； like a bloodhound on a trail。
〃You want to know about control mechanisms？〃 John Arnold said； turning in his chair in the control room。 The head engineer was a thin； tense； chain…smoking man of forty…five。 He squinted at the others in the room。 〃We have unbelievable control mechanisms；〃 Arnold said； and lit another cigarette。
〃For example；〃 Gennaro said。
〃For example； animal tracking。〃 Arnold pressed a button on his console； and the vertical glass map lit up with a pattern of jagged blue lines。 〃That's our juvenile T…rex。 The little rex。 All his movements within the park over the last twenty…four hours。〃 Arnold pressed the button again。 〃Previous twenty…four。〃 And again。 〃Previous twenty…four。〃
The lines on the map became densely overlaid； a child's scribble。 But the scribble was localized in a single area； near the southeast side of the lagoon。
〃You get a sense of his home range over time；〃 Arnold said。 〃He's young； so he stays close to the water。 And he stays away from the big adult rex。 You put up the big rex and the little rex； and you'll see their paths never cross。
〃Where is the big rex right now？〃 Gennaro asked。
Arnold pushed another button。 The map cleared； and a single glowing spot with a code number appeared in the fields northwest of the lagoon。 〃He's right there。〃
〃And the little rex？〃
〃Hell； I'll show you every animal in the park；〃 Arnold said。 The map began to light up like a Christmas tree； dozens of spots of light； each tagged with a code number。 〃That's two hundred thirty…eight animals as of this minute。〃
〃How accurate？〃
〃Within five feet。〃 Arnold puffed on the cigarette。 〃Let's put it this way： you drive out in a vehicle and you will find the animals right there； exactly as they're shown on the map。〃
〃How often is this updated？〃
〃Every thirty seconds。〃
〃Pretty impressive；〃 Gennaro said。 〃How's it done？〃
〃We have motion sensors all around the park；〃 Arnold said。 〃Most of 'em hard…wired； some radio…telemetered。 Of course； motion sensors won't usually tell you the species； but we get image recognition direct off the video。 Even when we're not watching the video monitors； the puter is。 And checking where everybody is。〃
〃Does the puter ever make a mistake？〃
〃Only with the babies。 It mixes those up sometimes； because they're such small images。 But we don't sweat that。 The babies almost always stay close to herds of adults。 Also you have the category tally。〃
〃What's that？〃
〃Once every fifteen minutes； the puter 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 puter can't make a mistake； because it pares 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 puter 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 v
