Giant bats fled south, and far ahead he saw a wide waterfall descending from the heavens. It was gone by the time he reached the damp sand of that place, but a dead shark lay to his left, and there was seaweed, seaweed, seaweed, fishes, driftwood all about.

The sky pinked over from east to west and remained that color. He gulped a bottle of ice water and felt it go into his stomach. He passed more cacti, and a pair of coyotes sat at the base of one and watched him drive by. They seemed to be laughing. Their tongues were very red.

As the sun brightened, he dimmed the screen. He smoked, and he found a button that produced music. He swore at the soft, stringy sounds that filled the cabin, but he didn't turn them off.

He checked the radiation level outside, and it was only a little above normal. The last time he had passed this way it had been considerably higher.

He passed several wrecked vehicles such as his own. He ran across another plain of silicon, and in the middle was a huge crater, which he skirted. The pinkness in the sky faded and faded and faded, and a bluish tone came to replace it. The dark lines were still there, and occasionally one widened into a black river as it flowed away into the east. At noon one such river partly eclipsed the sun for a period of eleven minutes. With its departure, there came a brief dust storm, and Tanner turned on the radar and his lights. He knew there was a chasm somewhere ahead, and when he came to it he bore to the left and ran along its edge for close to two miles before it narrowed and vanished. The other vehicles followed, and Tanner took his bearings from the compass once more. The dust had subsided with the brief wind, and even with the screen dimmed Tanner had to don his dark goggles against the glare of reflected sunlight from the faceted field be now negotiated.

He passed towering formations which seemed to be quartz. He had never stopped to investigate them in the past, and he had no desire to do it now. The spectrum danced at their bases, and patches of such light occurred for some distance about them.

Speeding away from the crater, he came again upon sand, clean, brown, white, dun, and red. There were more cacti, and huge dunes lay all about him. The sky continued to change, until finally it was as blue as a baby's eyes. Tanner hummed along with the music for a time, and then he saw the Monster.

It was a Gila, bigger than his car, and it moved in fast. It sprang from out the sheltering shade of a valley filled with cacti, and it raced toward him, its beaded body bright with many colors beneath the sun, its dark, dark eyes unblinking as it bounded forward on its lizard-fast legs, sable fountains rising behind its upheld tail, which was wide as a sail and pointed like a tent.

He couldn't use the rockets, because it was coming in from the side.

He opened up with his fifty-calibers and spread his "wings" and stamped the accelerator to the floor. As it neared, he sent forth a cloud of fire in its direction. By then, the other cars were firing, too.

It swung its tail and opened and closed its jaws, and its blood came forth and fell upon the ground. Then a rocket struck it. It turned, it leaped.

There came a booming, crunching sound as it fell upon the vehicle identified as car number one and lay there.

Tanner hit the brakes, turned, and headed back.

Car number three came up beside it and parked. Tanfler did the same.

He jumped down from the cab and crossed to the Smashed car. He had the rifle in his hands, and he put six rounds into the creature's head before he approached the car.

The door had come open, and it hung from a single hinge, the bottom one.

Inside, Tanner could see the two men sprawled, and there was some blood on the dashboard and the seat.

The other two drivers came up beside him and stared within. Then the shorter of the two crawled inside and listened for the heartbeat and the pulse and felt for breathing.

"Mike's dead," he called out, "but Greg's starting to come around."

A wet spot that began at the car's rear end spread and continued to spread, and the smell of gasoline filled the air.

Tanner took out a cigarette, thought better of it, and replaced it in the pack. He could hear the gurgle of the huge gas tanks as they emptied themselves upon the ground.

The man who stood at Tanner's side said, "I never saw anything like it... . I've seen pictures, but… I never saw anything like it..."

"I have," said Tanner, and then the other driver emerged from the wreck, partly supporting the man he'd referred to as Greg.

The man called out, "Greg's all right. He just hit his head on the dash."

The man who stood at Tanner's side said, "You can take him, Hell. He can back you up when he's feeling better," and Tanner shrugged and turned his back on the scene and lit a cigarette.

"I don't think you should do..." the man began, and "Screw," said Tanner, and blew smoke in his face. He turned to regard the two approaching men and saw that Greg was dark-eyed and deeply tanned. Part Indian, possibly. His skin seemed smooth, save for a couple pockmarks beneath his right eye, and his cheekbones were high and his hair very dark. He was as big as Tanner, which was six-two, though not quite so heavy. He was dressed in overalls, and his carriage, now that he had had a few deep breaths of air, became very erect, and he moved with a quick, graceful stride.

"We'll have to bury Mike," the short man said.

"I hate to lose the time," said his companion, "but..." And then Tanner flipped his cigarette and threw himself to the ground as it landed in the pool at the rear of the car.

There was an explosion, flames, then more explosions. Tanner heard the rockets as they tore off toward the east, inscribing dark furrows in the hot afternoon's air. The ammo for the fifty-calibers exploded, and the hand grenades went off, and Tanner burrowed deeper and deeper into the sand, covering his head and blocking his ears against the noise.

As soon as things grew quiet, he grabbed for the rifle. But they were already coming at him, and he saw the muzzle of a pistol. He raised his hands slowly and stood.

"Why the goddamn hell did you do a stupid thing like that?" said the other driver, the man who held the pistol.

Tanner smiled, and, "Now we don't have to bury him," he said. "Cremation's just as good, and it's already over."

"You could have killed us all if those guns or those rocket launchers had been aimed this way!"

"They weren't. I looked."

"The flying metal could've… Oh... . I see. Pick up your damn rifle, buddy, and keep it pointed at the ground. Eject the rounds it's still got in it and put 'em in your pocket."

Tanner did this thing while the other talked.

"You wanted to kill us all, didn't you? Then you could have cut out and gone your way, like you tried to do yesterday. Isn't that right?"

"You said it, mister, not me."

"It's true, though. You don't give a good goddamn if everybody in Boston croaks, do you?"

"My gun's unloaded now," said Tanner.

"Then get back in your bloody buggy and get going! I'll be behind you all the way!"

Tanner walked back toward his car. He heard the others arguing behind him, but he didn't think they'd shoot him. As he was about to climb up into the cab, he saw a shadow out of the corner of his eye and turned quickly.

The man named Greg was standing behind him, tail and quiet as a ghost.

"Want me to drive awhile?" he asked Tanner, without expression.

"No, you rest up. I'm still in good shape. Later on this afternoon, maybe, if you feel up to it."

The man nodded and rounded the cab. He entered from the other side and immediately reclined his chair.

Tanner slammed his door and started the engine. He heard the air-conditioner come to life.
