The diesel chose that moment to break down for good.
Clayton swore violently as he set the brakes. What lousy luck! If the wind were behind him, he could roll in. But, of course, it had to be in front.
"What are you going to do now?" Nerishev asked.
"I'm going to sit here," Clayton said. "When the wind calms down to a hurricane, I'm going to walk home."
The Brute's twelve-ton mass was shaking and rattling in the wind blasts.
"You know," Clayton said, "I'm going to retire after this tour."
"That so? You really mean it?"
"Absolutely. I own a farm in Maryland, with frontage on Chesapeake Bay. You know what I'm going to do?"
"What?"
"I'm going to raise oysters. You see, the oyster — hold it."
The station seemed to be drifting slowly upwind, away from him. Clayton rubbed his eyes, wondering if he were going crazy. Then he realized that, in spite of its brakes, in spite of its streamlining, the truck was being pushed downwind, away from the station.
Angrily he shoved a button on his switchboard, releasing the port and starboard anchors. He heard the solid clunk of the anchors hitting the ground, heard the steel cables scrape and rattle. He let out a hundred and seventy feet of steel line, then set the winch brakes. The truck was holding again.
"I dropped the anchors," Clayton said.
"Are they holding?"
"So far." Clayton lighted a cigarette and leaned back in his padded chair. Every muscle in his body ached from tension. His eyelids were twitching from watching the wind-lines converging on him. He closed his eyes and tried to relax.
The sound of the wind cut through the truck's steel plating. The wind howled and moaned, tugging at the truck, trying to find a hold on the smooth surface. At 169 miles at hour, the ventilator baffles blew out. He would be blinded, Clayton thought, if he weren't wearing sealed goggles, choked if he weren't breathing canned air. Dust swirled, thick and electric, within the Brute's cabin.
Pebbles, flung with the velocity of rifle bullets, splattered against the hull. They were striking harder now. He wondered how much more force they'd need before they started piercing the armor plating.
At times like this, Clayton found it hard to maintain a common sense attitude. He was painfully aware of the vulnerability of human flesh, appalled at the possibilities for violence in the Universe. What was he doing out here? Man's place was in the calm, still air of Earth. If he ever got back …
"Are you all right?" Nerishev asked.
"Making out just great," Clayton said wearily. "How are things at the station?"
"Not so good. The whole structure's starting sympathetic vibration. Enough wind for long enough and the foundations could shatter."
"And they want to put a fuel station here!" Clayton said.
"Well, you know the problem. This is the only solid planet between Angarsa III and the South Ridge Belt. All the rest are gas giants."
"They better build their station in space."
"The cost —"
"Hell, man, it'll cost less to build another planet than to try to maintain a fuel base on this one!" Clayton spat out a mouthful of dust. "I just want to get on that relief ship. How many natives at the station now?"
"About fifteen, in the shed."
"Any sign of violence?"
"No, but they're acting funny."
"How so?"
"I don't know," said Nerishev. "I just don't like it."
"Stay out of the shed, huh? You can't speak the language, anyhow, and I want you in one piece when I come back." He hesitated. "If I come back."
"You'll be fine," Nerishev said.
"Sure I will. I — oh, Lord!"
"What's it? What's wrong?"
"Boulder coming down! Talk to you later!"
Clayton turned his attention to the boulder, a rapidly growing black speck to windward. It was heading directly toward his anchored and immobilized truck. He glanced at the windspeed indicator. Impossible — 174 miles a hour! And yet, he reminded himself, winds in the stratospheric jet stream on Earth blow at 200 miles an hour.
The boulder, large as a house, still growing as it approached, was rolling directly his way.
"Swerve! Turn!" Clayton bellowed at the boulder, pounding the instrument panel with his fist.
The boulder was coming at him, straight as a ruler line, rolling right down the wind.
With a yell of agony, Clayton touched a button, releasing both anchors at the cable end. There was no time to winch them in, even assuming the winch could take the strain. Still the boulder grew.
Clayton released the brakes.
The Brute, shoved by a wind of 178 miles an hour, began to pick up speed. Within seconds, he was traveling at 38 miles an hour, staring through his rear-vision mirror at the boulder overtaking him.
As the boulder rolled up, Clayton twisted the steering wheel hard to the left. The truck tilted over precariously, swerved, fishtailed on the hard ground, and tried to turn itself over. He fought the wheel, trying to bring the Brute back to equilibrium. He thought: I'm probably the first man who ever jibed a twelve-ton truck!
The boulder, looking like a whole city block, roared past. The heavy truck teetered for a moment, then came to rest on its six wheels.
"Clayton! What happened? Are you all right?"
"Fine," Clayton gasped. "But I had to slip the cables. I'm running downwind."
"Can you turn?"
"Almost knocked her over, trying to."
"How far can you run?"
Clayton stared ahead. In the distance, he could make out the dramatic black cliffs that rimmed the plain.
"I got about fifteen miles to go before I pile into the cliffs. Not much time, at the speed I'm traveling." He locked his brakes. The tires began to scream and the brake linings smoked furiously. But the wind, at 183 miles an hour, didn't even notice the difference. His speed over the ground had picked up to 44 miles an hour.
"Try sailing her out!" Nerishev said.
"She won't take it."
"Try, man! What else can you do? The wind's hit 185 here. The whole station's shaking! Boulders are tearing up the whole post defense. I'm afraid some boulders are going to get through and flatten —"
"Stow it," Clayton said. "I got troubles of my own."
"I don't know if the station will stand! Clayton, listen to me. Try the —"
The radio suddenly and dismayingly went dead.
Clayton banged it a few times, then gave up. His speed over the ground reached 49 miles an hour. The cliffs were already looming large before him.
"So all right," Clayton said. "Here we go." He released his last anchor, a small emergency job. At its full length of 250 feet of steel cable, it slowed him to 30 miles an hour. The anchor was breaking and ripping through the ground like a jet-propelled plow.
Clayton then turned on the sail mechanism. This had been installed by the Earth engineers upon much the same theory that has small ocean-going motor boats carry a small mast and auxiliary sail. The sails are insurance, in case the engine fails. On Carella, a man could never walk home from a stranded vehicle. He had to come in under power.
The mast, a short, powerful steel pillar, extruded itself through a gasketed hole in the roof. Magnetic shrouds and stays snapped into place, supporting it. From the mast fluttered a sail made of link-woven metal. For a mainsheet, Clayton had a three-part flexible-steel cable, working through a winch.
The sail was only a few square feet in area. It could drive a twelve-ton monster with its brakes locked and an anchor out on 250 feet of line — easily — with the wind blowing 185 miles an hour.
Clayton winched in the mainsheet and turned, taking the wind on the quarter. But a quartering course wasn't good enough. He winched the sail in still more and turned further into the wind.
