As soon as he did, the branch bent down and the door swung wider, spilling him out of the Land Cruiser, and he fell-leaves scratching his face-his body bouncing from branch to branch-a jolt-searing pain, bright light in his head-

He slammed to a stop, the wind knocked from him. Tim lay doubled over a large branch, his stomach burning pain.

Tim heard another crack and looked up at the Land Cruiser, a big dark shape five feet above him.

Another crack. The car shifted.

Tim forced himself to move, to climb down. He used to like to climb trees. He was a good tree-climber. And this was a good tree to climb, the branches spaced close together, almost like a staircase…

Crackkkk…

The car was definitely moving.

Tim scrambled downward, slipping over the wet branches, feeling sticky sap on his hands, hurrying. He had not descended more than a few feet when the Land Cruiser creaked a final time, and then slowly, very slowly, nosed over. Tim could see the big green grille and the front headlights swinging down at him, and then the Land Cruiser fell free, gaining momentum as it rushed toward him, slamming against the branch where Tim had just been-

And it stopped.

His face just inches from the dented grille, bent inward like an evil mouth, headlamps for eyes. Oil dripped on Tim's face.

He was still twelve feet above the ground. He reached down, found another branch, and moved down. Above, he saw the branch bending under the weight of the Land Cruiser, and then it cracked, and the Land Cruiser came rushing down toward him and he knew he could never escape it, he could never get down fast enough, so Tim just let go.

He fell the rest of the way.

Tumbling, banging, feeling pain in every part of his body, hearing the Land Cruiser smashing down through the branches after him like a pursuing animal, and then Tim's shoulder hit the soft ground, and he rolled as hard as he could, and pressed his body against the trunk of the tree as the Land Cruiser tumbled down with a loud metallic crash and a sudden hot burst of electrical sparks that stung his skin and sputtered and sizzled on the wet ground around him.

Slowly, Tim got to his feet. In the darkness he heard the snuffling, and saw the stegosaur coming back, apparently attracted by the crash of the Land Cruiser. The dinosaur moved dumbly, the low head thrust forward, and the big cartilaginous plates running in two rows along the bump of the back. It behaved like an overgrown tortoise. Stupid like that. And slow.

Tim picked up a rock and threw it. "Get away!"

The rock tbunked dully off the plates. The stegosaur kept coming. "Go on! Co!"

He threw another rock, and hit the stegosaur in the head. The animal grunted, turned slowly away, and shuffled off in the direction it had come.

Tim leaned against the crumpled Land Cruiser and looked around in the darkness. He had to get back to the others, but he didn't want to get lost. He knew he was somewhere in the park, probably not far from the main road. If he could only get his hearings. He couldn't see much in the dark, but-

Then he remembered the goggles.

He climbed through the shattered front windshield into the Land Cruiser and found the night-vision goggles, and the radio. The radio was broken and silent, so he left it behind. But the goggles still worked. He flicked them on, saw the reassuringly familiar phosphorescent green image.

Wearing the goggles, he saw the battered fence off to his left, and walked toward it. The fence was twelve feet high, but the tyrannosaur had flattened it easily. Tim hurried across it, moved through an area of dense foliage, and came out onto the main road.

Through his goggles, he saw the other Land Cruiser turned on its side. He ran toward it, took a breath, and looked inside. The car was empty. No sign of Dr. Grant and Dr. Malcolm.

Where had they gone?

Where had everybody gone?

He felt sudden panic, standing alone in the jungle road at night with that empty car, and turned quickly in circles, seeing the bright green world in the goggles swirl. Something pale by the side of the road caught his eye. It was Lex's baseball. He wiped the mud off it.

"Lex!"

Tim shouted as loud as he could, not caring if the animals heard him. He listened, but there was only the wind, and the plink of raindrops falling from the trees.

" Lex!

He vaguely remembered that she had been in the Land Cruiser when the tyrannosaur attacked. Had she stayed there? Or had she gotten away? The events of the attack were confused in his mind. He wasn't exactly sure what had happened, just to think of it made him uneasy. He stood in the road, gasping with panic.

"Lex!"

The night seemed to close in around him. Feeling sorry for himself, he sat in a cold rainy puddle in the road and whimpered for a while. When he finally stopped, he still heard whimpering. It was faint, and it was coming from somewhere farther up the road.

"How long has it been?" Muldoon said, coming back into the control room. He was carrying a black metal case.

"Half an hour."

"Harding's Jeep should he back here by now."

Arnold stubbed out his cigarette. "I'm sure they'll arrive any minute now.

"Still no sign of Nedry?" Muldoon said.

"No. Not yet."

Muldoon opened the case, which contained six portable radios. "I'm going to distribute these to people in the building." He handed one to Arnold. "Take the charger, too. These are our emergency radios, but nobody had them plugged in, naturally. Let it charge about twenty minutes, and then try and raise the cars."

Henry Wu opened the door marked FERTILIZATION and entered the darkened lab. There was nobody here; apparently all the technicians were still at dinner. Wu went directly to the computer terminal and punched up the DNA logbooks. The logbooks had to be kept on computer. DNA was such a large molecule that each species required ten gigabytes of optical disk space to store details of all the iterations. He was going to have to check all fifteen species. That was a tremendous amount of information to search through.

He still wasn't clear about why Grant thought frog DNA was important. Wu himself didn't often distinguish one kind of DNA from another. After all, most DNA in living creatures was exactly the same. DNA was an incredibly ancient substance. Human beings, walking around in the streets of the modern world, bouncing their pink new babies, hardly stopped to think that the substance at the center of it all-the substance that began the dance of life-was a chemical almost as old as the earth itself. The DNA molecule was so old that its evolution had essentially finished more than two billion years ago. There had been little new since that time. Just a few recent combinations of the old genes-and not much of that.

When you compared the DNA of man and the DNA of a lowly bacterium, you found that only about 10 percent of the strands were different. This innate conservatism of DNA emboldened Wu to use whatever DNA he wished. In making his dinosaurs, Wu had manipulated the DNA as a sculptor might clay or marble. He had created freely.

He started the computer search program, knowing it would take two or three minutes to run. He got up and walked around the lab, checking instruments out of long-standing habit. He noted the recorder outside the freezer door, which tracked the freezer temperature. He saw there was a spike in the graph. That was odd, he thought. It meant somebody had been in the freezer. Recently, too-witbin the last half-hour. But who would go in there at night?

The computer beeped, signaling that the first of the data searches was complete. Wu went over to see what it had found, and when he saw the screen, he forgot all about the freezer and the graph spike.

The result was clear: all breeding dinosaurs incorporated rana, or frog, DNA. None of the other animals did. Wu still did not understand why this had caused them to breed. But he could no longer deny that Grant was right. The dinosaurs were breeding.

He hurried up to the control room.

She was curled up inside a big one-meter drainage pipe that ran under the road. She had her baseball glove in her mouth and she was rocking back and forth, banging her head repeatedly against the back of the pipe. It was dark in there, but he could see her clearly with his goggles. She seemed unhurt, and he felt a great burst of relief.

"Lex, it's me. Tim."

She didn't answer. She continued to bang her head on the pipe. "Come on out."

She shook her head no. He could see she was badly frightened.

"Lex," he said, "if you come out, I'll let you wear these night goggles."

She just shook her head.

"Look what I have," he said, holding up his band. She stared uncomprehendingly. It was probably too dark for her to see. "It's your ball, Lex. I found your ball."

"So what."

He tried another approach. "It must be uncomfortable in there. Cold, too. Wouldn't you like to come out?"

She resumed banging her head against the pipe.

"Why not?"

"There's aminals out there."

That threw him for a moment. She hadn't said "aminals" for years.

"The aminals are gone," he said.

"There's a big one. A Tyrannosaurus rex."

"He's gone."

"Where did he go?"

"I don't know, but he's not around here now," Tim said, hoping it was true.

Lex didn't move. He heard her hanging again. Tim sat down in the grass outside the pipe, where she could see him. The ground was wet where he sat. He hugged his knees and waited. He couldn't think of anything else to do. "I'm just going to sit here," he said. "And rest."

"Is Daddy out there?"

"No," he said, feeling strange. "He's back at home, Lex."

"Is Mommy?"

"No, Lex."

"Are there any grownups out there?" Lex said.

"Not yet. But I'm sure they'll come soon. They're probably on their way right now."

Then he heard her moving inside the pipe, and she came out. Shivering with cold, and with dried blood on her forehead, but otherwise all right.
