Farther South； other hadrosaurs were eating the lower vegetation。 Sometimes they reared up on their hind legs； resting their forelegs on the tree trunks； so they could reach the leaves on higher branches。 And in the far distance； a giant apatosaur stood above the trees； the tiny head swiveling on the long neck。 The scene was so peaceful Grant found it bard to imagine any danger。
〃Yew！〃 Lex shouted； ducking。 Two giant red dragonflies with six…foot wingspans bummed past them。 〃What was that？〃
〃Dragonflies；〃 he said。 〃The Jurassic was a time of huge insects。〃
〃Do they bite？〃 Lex said。
〃I don't think so；〃 Grant said。
Tim held out his band。 One of the dragonflies lighted on it。 He could feel the weight of the huge insect。
〃He's going to bite you；〃 Lex warned。
But the dragonfly just slowly flapped its red…veined transparent wings； and then； when Tim moved his arm； flew off again；
〃Which way do we go？〃 Lex said。
〃There。〃
They started walking across the field。 They reached a black box mounted on a heavy metal tripod； the first of the motion sensors。 Grant stopped and waved his band in front of it back and forth； but nothing happened。 If the phones didn't work； perhaps the sensors didn't work； either。 〃We'll try another one；〃 he said； pointing across the field。 Somewhere in the distance； they heard the roar of a large animal。
〃Ah hell；〃 Arnold said。 〃I just can't find it。〃 He sipped coffee and stared bleary…eyed at the screens。 He had taken all the video monitors off line。 In the control room； he was searching the puter code。 He was exhausted； he'd been working for twelve straight hours。 He turned to Wu； who had e up from the lab。
〃Find what？〃
〃The phones are still out。 I can't get them back on。 I think Nedry did something to the phones。〃
Wu lifted one phone； heard hissing。 〃Sounds like a modem。〃
〃But it's not；〃 Arnold said。 〃Because I went down into the basement and shut off all the modems。 What you're hearing is just white noise that sounds like a modem transmitting。〃
〃So the phone lines are jammed？〃
〃Basically； yes。 Nedry jammed them very well。 He's inserted some kind of a lockout into the program code； and now I can't find it； because I gave that restore mand which erased part of the program listings。 But apparently the mand to shut off the phones is still resident in the puter memory。〃
Wu shrugged。 〃So？ Just reset： shut the system down and you'll clear memory。
〃I've never done it before；〃 Arnold said。 〃And I'm reluctant to do it。 Maybe all the systems will e back on start…up…but maybe they won't。 I'm not a puter expert； and neither are you。 Not really。 And without an open phone line； we can't talk to anybody who is。〃
〃If the mand is RAM…resident； it won't show up in the code。 You can do a RAM dump and search that； but you don't know what you're searching for。 I think all you can do is reset。〃
Gennaro stormed in。 〃We still don't have any telephones。〃
〃Working on it。〃
〃You've been working on it since midnight。 And Malcolm is worse。 He needs medical attention。〃
〃It means I'll have to shut down；〃 Arnold said。 〃I can't be sure everything will e back on。〃
Gennaro said； 〃Look。 There's a sick man over in that lodge。 He needs a doctor or he'll die。 You can't call for a doctor unless you have a phone。 Four people have probably died already。 Now； shut down and get the phones working！〃
Arnold hesitated。
〃Well？〃 Gennaro said。
〃Well； it's just 。 。 。 the safety systems don't allow the puter to be shut down； and…〃
〃Then turn the goddamn safety systems off！ Can't you get it through your head that he's going to die unless he gets help？〃
〃Okay；〃 Arnold said。
He got up and went to the main panel。 He opened the doors； and uncovered the metal swing…latches over the safety switches。 He popped them off； one after another。 〃You asked for it；〃 Arnold said。 〃And you got it。〃
He threw the master switch。
The control room was dark。 All the monitors were black； The three men stood there in the dark。
〃How long do we have to wait？〃 Gennaro said。
〃Thirty seconds；〃 Arnold said。
〃P…U！〃 Lex said； as they crossed the field。
〃What？〃 Grant said。
〃That smell！〃 Lex said。 〃It stinks like rotten garbage。〃
Grant hesitated。 He stared across the field toward the distant trees； looking for movement。 He saw nothing。 There was hardly a breeze to stir the branches。 It was peaceful and silent in the early morning。 〃I think it's your imagination；〃 he said。
〃Is not…〃
Then he heard the honking sound。 It came from the herd of duckbilled hadrosaurs behind them。 First one animal； then another and another； until the whole herd had taken up the honking cry。 The duckbills were agitated； twisting and turning； hurrying out of the water； circling the young ones to protect them。 。 。 。
They smell it； too； Grant thought。
With a roar； the tyrannosaur burst from the trees fifty yards away； near the lagoon。 It rushed out across the open field with huge strides。 It ignored them； heading toward the herd of hadrosaurs。
〃I told you！〃 Lex screamed。 〃Nobody listens to me！〃
In the distance； the duckbills were honking and starting to run。 Grant could feel the earth shake beneath his feet。 〃e on； kids！〃 He grabbed Lex； lifting her bodily off the ground； and ran with Tim through the grass。 He had glimpses of the tyrannosaur down by the lagoon； lunging at the hadrosaurs； which swung their big tails in defense and bonked loudly and continuously。 He heard the crashing of foliage and trees； and when he looked over again； the duckbills were charging。
In the darkened control room； Arnold checked his watch。 Thirty seconds。 The memory should be cleared by now。 He pushed the main power switch back on。
Nothing happened。
Arnold's stomach heaved。 He pushed the switch off； then on again。 Still nothing happened。 He felt sweat on his brow。
〃What's wrong？〃 Gennaro said。
〃Oh hell；〃 Arnold said。 Then he remembered you had to turn the safety swiitches back on before you restarted the power。 He flipped on the three safeties； and covered them again with the latch covers。 Then he held his breath； and turned the main power switch。
The room lights came on。
The puter beeped。
The screens hummed。
〃Thank God；〃 Arnold said。 He hurried to the main monitor。 There were rows of labels on the screen
Gennaro reached for the phone； but it was dead。 No static hissing this time…just nothing at all。 〃What's this？〃
〃Give me a second；〃 Arnold said。 〃After a reset； all the system modules have to be brought on line manually。〃 Quickly； he went back to work。
〃Why manually？〃 Gennaro said。
〃Will you just let me work； for Christ's sake？〃
Wu said； 〃The system is not intended to ever shut down。 So； if it does shut down； it assumes that there is a problem somewhere。 It requires you to start up everything manually； Otherwise； if there were a short somewhere； the system would start up； short out； start up again； short out again； in an endless cycle。〃
Okay；〃 Arnold said。 〃We're going。〃
Gennaro picked up the phone and started to dial； when he suddenly stopped。
〃Jesus； look at that；〃 he said。 He pointed to one of the video monitors。
But Arnold wasn't listening； He was staring at the map； where a tight cluster of dots by the lagoon had started to move in a coordinated way。 Moving fast； in a kind of swirl。
〃What's happening？〃 Gennaro said。
〃The duckbills；〃 Arnold said tonelessly。 〃They've stampeded。〃
The duckbills charged with surprising speed； their enormous bodies in a tight cluster； honking and roaring； the infants squealing and trying to stay out from underfoot。 The herd raised a great cloud of yellow dust。 Grant couldn't see the tyrannosaur。
The duckbills were running right toward them。
Still carrying Lex； he ran with Tim toward a rocky outcrop； with a stand of big conifers。 They ran hard； feeling the ground shake beneath their feet。 The sound of the approaching herd was deafening； like the sound of jets at an airport。 It filled the air； and hurt their ears。 Lex was shouting something； but he couldn't hear what she was saying； and as
