The Unorthodox Engineers

operations. Fritz, I want you to provide them with transport to where they’ll be most use—and if you don’t, you’d better find some other engineering reserve to come back to…”

“Yes, sir,” said Fritz unhappily, “I get the point.”

“You know, Fritz,” said Colonel Belling, “I think we may finally have reached a point of real understanding!” He grinned wolfishly. “I’m going to rather enjoy the thoughts of you and the U.E. squad sweating it out in a hell- spot like Tazoo.”

Touchdown on Tazoo. The transfer ferry had no viewports and afforded no opportunity for its passengers to receive a preview of their destination. Even the ground-cat which rendezvoused at the landing site close-coupled its hatches with the ferry’s air lock before the transfer of passengers and goods began. In the cabin of the ground-cat, shutters likewise obscured the view and cheated Fritz of his moment of revelation.

“Allow me to introduce myself,” said the cabin’s occupant. “I’m Philip Nevill, Archaeologist in charge of this project.”

“Van Noon,” said Fritz. “Engineer extraordinary—and this is Jacko Hine, one of my staff.”

Nevill grinned affably. “Your reputation preceded you, Lieutenant. Frankly, when I heard of you I persuaded Colonel Nash to get the U.E. squad here at any cost. There are things on Tazoo it’ll take a very liberal mind indeed to understand.”

The ground-cat struggled away from the ferry, its treads crunching through the sand and its engine coughing in asthmatic complaint.

“So I’ve heard,” said Fritz. “Look, do you mind if I open the shutter for a second? I’d like to know the worst right from the start.”

“Help yourself,” said Nevill, “but I promise you it’s a passion you’ll soon lose.”

Fritz fought the shutter from the window and peered out for his first glimpse of Tazoo. Heavy ochre- coloured cloudbanks filtered the furious sunlight to a baleful glare, and rendered all colours as murky shades of reds and browns. Black shadow cut the view into odd-shaped segments. The terrain itself was nothing but a lumpy, featureless waste as far as the eye could see.

“Satisfied?” asked Nevill.

Fritz dropped the shutter back and closed his eyes.

“Painful, isn’t it?” asked Nevill. “Normal endurance is about forty minutes before red-blindness sets in. Very bad for the eyes, to say nothing of the psychological effects. And as if that were not bad enough; the planet has no ozone-layer, so ultraviolet radiation is extremely severe at all times.”

At the blare of the ground-cat’s horn Nevill opened the shutter again. “There’s the base—way over yonder.”

Fritz scowled at the deep-red panorama. Perhaps half a kilometre away was the base, like a cluster of cherries half-submerged in a basin of dirty pink icing.

“Underground, eh? A very sensible precaution.”

“It isn’t underground,” said Nevill in a slightly aggrieved tone. “It’s a surface installation.”

“But I don’t see anything but some almighty balls of mud.”

“They’re standard Knudsen huts with a protective skin on. There’s a sandstorm that whips up every night which would sandblast an unprotected Knudsen to a skeleton before dawn. We spray each hut weekly with a highly plasticized poly-polymer which is reasonably abrasive resistant. The plastic traps some of the sand and this materially increases its resistance, but builds up and completely ruins the shape.”

Abruptly the engine of the ground-cat coughed and died. Nevill held a rapid exchange over the intercom with the driver.

“Engine’s gone,” he said finally. “Either the carburettor’s etched away or the damn sand has got into the cylinders— probably both. Anyway, this cat is a write-off for all practical purposes, so there’s nothing for it but to walk—and it’s too near evening for that to be funny.”

They descended from the cabin, Fritz and Jacko choking quietly in the acrid air which caught at their noses and seared their lungs. Nevill, more acclimatized, was surveying the sky anxiously. Above them the swirling cloudbanks, smokey-red trailing into purple and black, plunged across the darkening sky so low that Fritz had an almost compulsive desire to put up his hands to see if he could touch them. There must have been a strong wind above, for the cloudrace was certainly moving at a significant clip, yet on the ground the warm humidity was almost deathly still, as though a sheet of glass insulated them from the driving turbulence above.

“Looks like a storm,” Nevill muttered in a worried voice.

“Is that bad?” asked Fritz.

“Terminal if you’re unlucky enough to be out in it. Let’s hope it’s a wet storm. They’re decidedly uncomfortable, but not usually fatal if you can get to shelter quickly enough,”

“Why, what happens?”

“Nothing spectacular if you can find shelter from a hundred kilometre per hour damp sandstorm, and if you happen to have sufficient alkali available to neutralize the rain on your skin.”

“Neutralize the rain?” said Fritz, his voice rising. “What the hell is in it?”

“Oh, about five per cent sulphuric acid plus a trace of hydrogen chloride with a little free ionized chlorine. Stings like crazy, I can assure you. But it’s better than a dry storm.”

“I’ll buy it,” Fritz said helplessly. “If a wet sandstorm is equal to an accelerated metal descaling process, what’s a dry storm equal to?”

By now Nevill was deeply concerned, scanning the furious cloudrace with worried and experienced eyes. They were still three hundred metres from the nearest part of the base, with Jacko and the driver close behind.

“I think you’re going to have a practical demonstration of a dry storm, Lieutenant. If the smell of ozone becomes intolerable or if you hear anything like a bee buzzing don’t hesitate —just drop to the ground as fast as you are able. If you can find a hollow then roll into it, but whatever you do, be quick.”

“A bee buzzing?”

“Air ionization path, the prelude to a lightning bolt. The cloudrace generates several megavolts, and it packs a current that can fuse you very neatly into the sand. The carbon from the body reduces a great many metal oxides in the ground so that the resultant slag forms a remarkable range of glasses.” He looked round and Fritz saw the concern in his eyes. “I’ve seen it happen—not pretty!”

“Forget the chemistry lesson,” Chimed in Jacko. “I never could see myself making a very convincing paperweight.”

“Then dropI” said Nevill, suiting action to the words.

They all hit the ground. Fritz’s nose didn’t have time to detect the ozone, virtually paralysed as it was by the existing acridity, but his ears did register the sudden buzz which Nevill had anticipated by a half second. Then the lightning discharge, a crack of vivid energy a mere thirty metres distant. The noise and the shock-wave of its passing stunned them momentarily. By the time they had collected their wits only a generous patch of fused sand and a choking concentration of ozone marked the spot where the bolt had struck.

“Bad!” said Nevill, “Worst I’ve seen for some time. It’s striking low ground, which means we have no possible cover out here. Best to crawl back nearer to the cat—but for God’s sake keep your heads low.”

“But—” Fritz protested.

Another bolt of lightning, bigger and nearer than the first, stabbed into the sand behind them like the bursting of a shell, followed by three almost simultaneously in the near vicinity.

Desperately slowly the party crawled back towards the cat, which stood as the pitifully-low high-spot of this particular area of terrain. On all sides of them now the jagged lightning cut into the ground with burning shafts of vicious energy, like the arrows of retribution fired by some crazed electric god. Then a shaft burned down on the cat itself. The vehicle sagged in on itself and molten metal seeped down its flanks and dripped onto the red sand of Tazoo.

“Treads!” Shouted Fritz van Noon, spitting sand. “The bloody treads are metal!”

“Jesus!” muttered Jacko, “we’ve been travelling in a glorified lightning-conductor!”

Then mercifully it began to rain. Nevill turned his face to the stinging, acrid precipitation and let out a howl
