〃Yeah。〃
Thorne shrugged。 〃That might work;〃 he said。 〃But without testing; we can't know how long the cast will last。 Might be a few days; it might be a few months。〃
〃That's too long;〃 Sarah said。 〃This animal is growing rapidly。 If growth is constricted; it'll end up being crippled by the cast。〃
〃What we need;〃 Eddie said; 〃is an organic resin that will form a decaying binder。 Like a gum of some kind。〃
〃Chewing gum?〃 Arby said。 〃Because I have plenty of … 〃
〃No; I was thinking of a different kind of gum。 Chemically speaking; the diesterase resin … 〃
〃We'll never solve it chemically;〃 Thorne said。 〃We don't have the supplies。〃
〃What else can we do? There's no choice but … 〃
〃What if you make something that's different in different directions?〃 Arby said。 〃Strong one way and weak in another?〃
〃You can't;〃 Eddie said。 〃It's a homogeneous resin。 It's all the same stuff; goopy glue that turns rock…hard when it dries; and … 〃
〃No; Wait a minute;〃 Thorne said; turning to the boy。 〃What do you mean; Arby?〃
〃Well;〃 Arby said; 〃Sarah said the leg is growing。 That means it's; going to grow longer; which doesn't matter for a cast; and wider; which does; because it'll start to squeeze the leg。 But if you made it weak in the diameter … 〃
〃He's right;〃 Thorne said。 〃We can solve it structurally。〃
〃How?〃 Eddie said。
〃Just build in a split…line。 Maybe using aluminum foil。 We have some for cooking。〃
〃That'd be much too weak;〃 Eddie said。
〃Not if we coat it with a layer of resin。〃 Thorne turned to Sarah。 〃What we can do is make a cast that is very strong for vertical stresses; but weak for lateral stresses。 It's a simple engineering problem。 The baby can walk around on its cuff; and everything is fine; as long as the stresses are; vertical。 But when its leg grows; it will pop the split…line open; and the cuff will fall away。〃
〃Yes;〃 Arby said; nodding。
〃Is that hard to do?〃 she said。
〃No。 It should be pretty easy。 You just build a cuff of aluminum foil; and coat it with resin。〃
Eddie said; 〃And what'll hold the cuff together while you coat it。
〃How about chewing gum?〃 Arby said。
〃You got it;〃 Thorne said; smiling。
At that moment; the baby rex stirred; its legs twitching。 It raised its head; the oxygen mask dropping away; and gave a low; weak squeak。
〃Quickly;〃 Sarah said; grabbing the head。 〃More morphine。〃
Malcolm had a syringe ready。 He jabbed it into the animal's neck。
〃Just five cc's now;〃 Sarah said。
〃What's wrong with more? Keep him out longer?〃
〃He's in shock from the injury; Ian。 You can kill him with too much morphine。 You'll put him into respiratory arrest。 His adrenal glands are probably stressed; too。〃
〃If he even has adrenals; 〃 Malcolm said。 〃Does a Tyrannosaurus rex have hormones at all? The truth is; we don't know anything about these animals。〃
The radio clicked; and Levine said; 〃Speak for yourself; Ian。 In point of fact; I suspect we will find that dinosaurs have hormones。 There are pelling reasons to imagine they do。 As long as you have gone to the misguided trouble of taking the baby; you might draw some tubes of blood。 Meanwhile; Doc; could you pick up the phone?〃
Malcolm sighed。 〃That guy;〃 he said; 〃is starting to get on my nerves。〃
Thorne moved down the trailer to the munications module near the front。 Levine's request was odd; there was a perfectly good system of microphones throughout the trailer。 But Levine knew that; he had designed the system himself。
Thorne picked up the phone。 〃Yes?
〃Doc;〃 Levine said; 〃I'll get right to the point。 Bringing the baby to the trailer was a mistake。 It's asking for trouble。〃
〃What sort of trouble?〃
〃We don't know; is the point。 And I don't want to alarm anybody。 But why don't you bring the kids out to the high hide for a while? And why don't you and Eddie e; too?〃
〃You're telling me to get the hell out of here。 You really think it's necessary?〃
〃In a word;〃 Levine said; 〃yes。 I do。〃
As the morphine was injected into the baby; he gave a sighing wheeze and collapsed back onto the steel pan。 Sarah adjusted the oxygen mask around his face。 She glanced back at the monitor; checking the heart rate; but once again Arby and Kelly were blocking her view。 〃Kids; please。〃
Thorne stepped forward; clapped his bands。 〃Okay; kids! Field trip! Let's get moving。〃
Arby said; 〃Now? But we want to watch the baby … 〃
〃No; no;〃 Thorne said。 〃Dr。 Malcolm and Dr。 Harding need room to work。 This is the time for a field trip to the high hide。 We can watch the dinosaurs for the rest of the afternoon。〃
〃But Doc … 〃
〃Don't argue。 We're just in the way here; and we're going;〃 Thorne said。 〃Eddie; you e; too。 Leave these two lovebirds to do their work。〃
In a few moments; they left。 The trailer door slammed shut behind them。 Sarah Harding heard the soft whirr of the Explorer as it drove away。 Bent over the baby; adjusting the oxygen mask; she said; 〃Lovebirds?〃
Malcolm shrugged。 〃Levine。。。〃
〃Was this Levine's idea? Clearing everybody out?〃
〃Probably。〃
〃Does he know something we don't?〃
Malcolm laughed。 〃I'm sure he thinks he does。〃
〃Well; let's start the cast;〃 she said。 〃I want to get it done quickly; and take this baby home again。〃
The High Hide
The sun had disappeared behind low…banging clouds by the time they reached the high hide。 The entire valley was bathed in a soft reddish glow as Eddie parked the Explorer beneath the aluminum scaffolding; and they all climbed up to the little shelter above。 Levine was there; binoculars to his eyes。 He did not seem glad to see them。 〃Stop moving around so much;〃 he said irritably。
From the shelter; they had a magnificent view over the valley。 Somewhere in the north; thunder rumbled。 The air was cooling; and felt electric。
〃Is there going to be a storm?〃 Kelly asked。
〃Looks like it;〃 Thorne said。
Arby glanced doubtfully at the metal roof of the shelter。 〃How long are we staying out here?〃
〃For a while;〃 Thorne said。 〃This is our only ay here。 The helicopters are taking us away tomorrow morning。 I thought you kids deserved a chance to see the dinosaurs in the field one more time。〃
Arby squinted at him。 〃What's the real reason?〃
〃I know;〃 Kelly said; in a worldly tone。
〃Yeah? What?〃
〃Dr。 Malcolm wants to be alone with Sarah; stupid。〃
〃Why?〃
〃They're old friends;〃 Kelly said。
〃So? We were just going to watch。〃
〃No;〃 Kelly said。 〃I mean; they're old friends。〃
〃I know what you're talking about;〃 Arby said。 〃I'm not stupid; you know。〃
〃Knock it off;〃 Levine said; staring through the binoculars。 〃You're missing the interesting stuff。〃
〃What's that?〃
〃Those triceratops; down at the river。 Something's bothering them。〃
The triceratops herd had been drinking peacefully from the river; but now they were beginning to make noise。 For such huge animals; their vocalizations were incongruously high…pitched: they sounded more like yelping dogs。
Arby turned to look。 〃There's something in the trees;〃 he said; 〃across the river。〃 There was some hint of dark movement; beneath the trees。
The triceratops herd shifted; and began backing toward each other until they formed a sort of rosette; with their curved horns facing outward; against the unseen menace。 The solitary baby was in the center; yelping in fear。 One of the animals; presumably its mother; turned and nuzzled it。 Afterward; the baby was silent。
〃I see them;〃 Kelly said; staring at the trees。 〃They're raptors。 Over there。〃
The triceratops herd faced the raptors; the adults barking as they swung their sharp horns up and down。 They created a kind of barrier of moving spikes。 There was an unmistakable sense of coordination; of group defense against predators。
Levine was smiling happily。 〃There's never been any evidence for this;〃 he said; suddenly cheerful。 〃In fact; most paleontologists don't believe it happens。〃
〃Don't believe what happens?〃 Arby said。
〃This kind of group defensive behavior。 Especially with trikes … they look a bit like rhinos; so they've been assu
