Paul, crowded into a corner by sweating men, smelled the perspiration of fear, saw that two of the men had poor neck adjustments on their stillsuits. He filed the information in his memory for future action. His father would have to

order tighter stillsuit discipline. Men tended to become sloppy if you didn't watch such things.

The last man came gasping into the rear, said. "The worm! It's almost on us!

Blast off!"

The Duke slid into his seat, frowning, said: "We still have almost three minutes on the original contact estimate. Is that right, Kynes?" He shut his door, checked it.

"Almost exactly, my Lord," Kynes said, and he thought: A cool one, this duke.

"All secure here, Sire," Halleck said.

The Duke nodded, watched the last of his escort take off. He adjusted the igniter, glanced once more at wings and instruments, punched the jet sequence.

The take-off pressed the Duke and Kynes deep into their seats, compressed the people in the rear. Kynes watched the way the Duke handled the controls--

gently, surely. The 'thopter was fully airborne now, and the Duke studied his instruments, glanced left and right at his wings.

"She's very heavy, Sire," Halleck said.

"Well within the tolerances of this ship," the Duke said. "You didn't really think I'd risk this cargo, did you, Gurney?"

Halleck grinned, said: "Not a bit of it, Sire."

The Duke banked his craft in a long easy curve--climbing over the crawler.

Paul, crushed into a corner beside a window, stared down at the silent machine on the sand. The wormsign had broken off about four hundred meters from the crawler. And now, there appeared to be turbulence in the sand around the factory.

"The worm is now beneath the crawler," Kynes said. "You are about to witness a thing few have seen."

Flecks of dust shadowed the sand around the crawler now. The big machine began to tip down to the right. A gigantic sand whirlpool began forming there to the right of the crawler. It moved faster and faster. Sand and dust filled the air now for hundreds of meters around.

Then they saw it!

A wide hole emerged from the sand. Sunlight flashed from glistening white spokes within it. The hole's diameter was at least twice the length of the crawler, Paul estimated. He watched as the machine slid into that opening in a billow of dust and sand. The hole pulled back.

"Gods, what a monster!" muttered a man beside Paul.

"Got all our floggin' spice!" growled another.

"Someone is going to pay for this," the Duke said. "I promise you that."

By the very flatness of his father's voice, Paul sensed the deep anger. He found that he shared it. This was criminal waste!

In the silence that followed, they heard Kynes.

"Bless the Maker and His water," Kynes murmured. "Bless the coming and going of Him. May His passage cleanse the world. May He keep the world for His people."

"What's that you're saying?" the Duke asked.

But Kynes remained silent.

Paul glanced at the men crowded around him. They were staring fearfully at the back of Kynes' head. One of them whispered: "Liet."

Kynes turned, scowling. The man sank back, abashed.

Another of the rescued men began coughing--dry and rasping. Presently, he gasped: "Curse this hell hole!"

The tall Dune man who had come last out of the crawler said; "Be you still, Coss. You but worsen your cough." He stirred among the men until he could look through them at the back of the Duke's head. "You be the Duke Leto, I warrant,"

he said. "It's to you we give thanks for our lives. We were ready to end it there until you came along."

"Quiet, man, and let the Duke fly his ship," Halleck muttered.

Paul glanced at Halleck. He, too, had seen the tension wrinkles at the corner of his father's jaw. One walked softly when the Duke was in a rage.

Leto began easing his 'thopter out of its great banking circle, stopped at a new sign of movement on the sand. The worm had withdrawn into the depths and now, near where the crawler had been, two figures could be seen moving north away from the sand depression. They appeared to glide over the surface with hardly a lifting of dust to mark their passage.

"Who's that down there?" the Duke barked.

"Two Johnnies who came along for the ride, Soor," said the tall Dune man.

"Why wasn't something said about them?"

"It was the chance they took, Soor," the Dune man said.

"My Lord," said Kynes, "these men know it's of little use to do anything about men trapped on the desert in worm country."

"We'll send a ship from base for them!" the Duke snapped.

"As you wish, my Lord," Kynes said. "But likely when the ship gets here there'll be no one to rescue."

"We'll send a ship, anyway," the Duke said.

"They were right beside where the worm came up," Paul said. "How'd they escape?"

"The sides of the hole cave in and make the distances deceptive," Kynes said.

"You waste fuel here, Sire," Halleck ventured.

"Aye, Gurney."

The Duke brought his craft around toward the Shield Wall. His escort came down from circling stations, took up positions above and on both sides.

Paul thought about what the Dune man and Kynes had said. He sensed half-truths, outright lies. The men on the sand had glided across the surface so surely, moving in a way obviously calculated to keep from luring the worm back out of its depths.

Fremen! Paul thought. Who else would be so sure on the sand? Who else might be left out of your worries as a matter of course--because they are in no danger? They know how to live here! They know how to outwit the worm!
