〃They got my glove；〃 Lex said。 〃My Darryl Strawberry special。〃
They started walking again。 Tim put his arm around her shoulders。 〃Are you all right？〃
〃Of course； stupid；〃 she said； shaking him off。 She looked upward。 〃I hope they choke and die；〃 she said。
〃Yeah；〃 Tim said。 〃Me； too…〃
Up ahead； they saw the boat on the shore。 Grant looked at his watch。 It was eight…thirty。 He now had two and a half hours to get back。
Lex cheered as they drifted beyond the silver aviary dome。 Then the banks of the river closed in on both sides； the trees meeting overhead once more。 The river was narrower than ever； in some places only ten feet wide； and the current flowed very fast。 Lex reached up to touch the branches as they went past。
Grant sat back in the raft and listened to the gurgle of the water through the warm rubber。 They were moving faster now； the branches overhead slipping by more rapidly。 It was pleasant。 It gave a little breeze in the hot confines of the overhanging branches。 And it meant they would get back that much sooner。
Grant couldn't guess how far they had e； but it must be several miles at least from the sauropod building where they had spent the night。 Perhaps four or five miles。 Maybe even more。 That meant they might be only an hour's walk from the hotel； once they left the raft。 But after the aviary； Grant was in no hurry to leave the river again。 For the moment； they were making good time。
〃I wonder how Ralph is；〃 Lex said。 〃He's probably dead or something。〃
〃I'm sure he's fine。〃
〃I wonder if he'd let me ride him。〃 She sighed； sleepy in the sun。 〃That would be fun； to ride Ralph。〃
Tim said to Grant； 〃Remember back at the stegosaurus？ Last night？〃
〃Yes。〃
〃How e you asked them about frog DNA？〃
〃Because of the breeding；〃 Grant said。 〃They can't explain why the dinosaurs are breeding； since they irradiate them； and since they're all females。〃
〃Right。〃
〃Well； irradiation is notoriously unreliable and probably doesn't work。 I think that'll eventually be shown here。 But there is still the problem of the dinosaurs' being female。 How can they breed when they're all female？〃
〃Right；〃 Tim said。
〃Well； across the animal kingdom； sexual reproduction exists in extraordinary variety。〃
〃Tim's very interested in sex；〃 Lex said。
They both ignored her。 〃For example；〃 Grant said； 〃many animals have sexual reproduction without ever having what we would call sex。 The male releases a spermatophore； which contains the sperm； and the female picks it up at a later time。 This kind of exchange does not require quite as much physical differentiation between male and female as we usually think exists。 Male and female are more alike in some animals than they are in human beings。〃
Tim nodded。 〃But what about the frogs？〃
Grant heard sudden shrieks from the trees above； as the microceratopsians scattered in alarm； shaking the branches。 The big head of the tyrannosaur lunged through the foliage from the left； the jaws snapping at the raft。 Lex howled in terror； and Grant paddled away toward the opposite bank； but the river here was only ten feet wide。 The tyrannosaur was caught in the heavy growth… it butted and twisted its head； and roared。 Then it pulled its head back。
Through the trees that lined the riverbank； they saw the huge dark form of the tyrannosaur； moving north； looking for a gap in the trees that lined the bank。 The microceratopsians had all gone to the opposite bank； where they shrieked and scampered and jumped up and down。 In the raft； Grant； Tim； and Lex stared helplessly as the tyrannosaur tried to break through again； But the trees were too dense along the banks of the river。 The tyrannosaur again moved downstream； ahead of the boat； and tried again； shaking the branches furiously。
But again it failed。
Then it moved off； heading farther downstream。
〃I hate him；〃 Lex said。
Grant sat back in the boat； badly shaken。 If the tyrannosaur had broken through； there was nothing be could have done to save them。 The river was so narrow that it was hardly wider than the raft。 It was like being in a tunnel。 The rubber gunwales often scraped on the mud as the boat was pulled along by the swift current。
He glanced at his watch。 Almost nine。 The raft continued downstream。
〃Hey；〃 Lex said； 〃listen！〃
He heard snarling； interspersed by a repeated hooting cry。 The cries were ing from beyond a curve； farther downriver。 He listened； and heard the hooting again。
〃What is it？〃 Lex said。
〃I don't know；〃 Grant said。 〃But there's more than one of them。〃 He paddled the boat to the opposite bank； grabbed a branch to stop the raft。 The snarling was repeated。 Then more hooting。
〃It sounds like a bunch of owls；〃 Tim said。
Malcolm groaned。 〃Isn't it time for more morphine yet？〃
〃Not yet；〃 Ellie said。
Malcolm sighed。 〃How much water have we got here？〃
〃I don't know。 There's plenty of running water from the tap…〃
〃No； I mean； how much stored？ Any？〃
Ellie shrugged。 〃None。〃
〃Go into the rooms on this floor；〃 Malcolm said； 〃and fill the bathtubs with water。〃
Ellie frowned。
〃Also；〃 Malcolm said； 〃have we got any walkie…talkies？ Flashlights？ Matches？ Sterno stoves？ Things like that？〃
〃I'll look around。 You planning for an earthquake？〃
〃Something like that；〃 Malcolm said。 〃Malcolm Effect implies catastrophic changes。〃
〃But Arnold says all the systems are working perfectly。〃
〃That's when it happens；〃 Malcolm said。
Ellie said； 〃You don't think much of Arnold； do you？〃
〃He's all right。 He's an engineer。 Wu's the same。 They're both technicians。 They don't have intelligence。 They have what I call 'thintelligence。' They see the immediate situation。 They think narrowly and they call it 'being focused。' They don't see the surround。 They don't see the consequences。 That's how you get an island like this。 From thintelligent thinking。 Because you cannot make an animal and not expect it to act alive。 To be unpredictable。 To escape。 But they don't see that。〃
〃Don't you think it's just human nature？〃 Ellie said。
〃God； no；〃 Malcolm said。 〃That's like saying scrambled eggs and bacon for breakfast is human nature。 It's nothing of the sort。 It's uniquely Western training； and much of the rest of the world is nauseated by the thought of it。〃 He winced in pain。 〃The morphine's making me philosophical。〃
〃You want some water？〃
〃No。 I'll tell you the problem with engineers and scientists。 Scientists have an elaborate line of bullshit about how they are seeking to know the truth about nature。 Which is true； but that's not what drives them。 Nobody is driven by abstractions like 'seeking truth。'
〃Scientists are actually preoccupied with acplishment。 So they are focused on whether they can do something。 They never stop to ask if they should do something。 They conveniently define such considerations as pointless。 If they don't do it； someone else will。 Discovery； they believe； is inevitable。 So they just try to do it first。 That's the game in science。 Even pure scientific discovery is an aggressive； penetrative act。 It takes big equipment； and it literally changes the world afterward。 Particle accelerators sear the land； and leave radioactive byproducts。 Astronauts leave trash on the moon。 There is always some proof that scientists were there； making their discoveries。 Discovery is always a rape of the natural world。 Always。
〃The scientists want it that way。 They have to stick their instruments in。 They have to leave their mark。 They can't just watch。 They can't just appreciate。 They can't just fit into the natural order。 They have to make something unnatural happen。 That is the scientist's job； and now we have whole societies that try to be scientific。〃 He sighed； and sank back。
Ellie said； 〃Don't you think you're overstating…〃
〃What does one of your excavations look like a year later？〃
〃Pretty had；〃 she admitted。
〃You don't replant； you don't restore the land after you dig？〃
〃No。〃
〃Why not？〃
She shrugged。 〃There's no money； I guess。 。 。 。
〃There's only enough money to dig； but not to repair？〃
〃Well
