She stepped past Paul, lifted her binoculars, adjusted the oil lenses and studied the escarpment across from them. Yes, saguaro in the arroyos and other spiny growth . . . and a matting of low grasses, yellow-green in the shadows.
"I'll strike camp," Paul said.
Jessica nodded, walked to the fissure's mouth where she could get a sweep of the desert, and swung her binoculars to the left. A salt pan glared white there with a blending of dirty tan at its edges - a field of white out here where white was death. But the pan said another thing: water . At some time water had flowed across that glaring white. She lowered her binoculars, adjusted her burnoose, listened for a moment to the sound of Paul's movements.
The sun dipped lower. Shadows stretched across the salt pan. Lines of wild color spread over the sunset horizon. Color streamed into a toe of darkness testing the sand. Coal-colored shadows spread, and the thick collapse of night blotted the desert.
Stars!
She stared up at them, sensing Paul's movements as he came up beside her. The desert night focused upward with a feeling of lift toward the stars. The weight of the day receded. There came a brief flurry of breeze across her face.
"The first moon will be up soon," Paul said. "The pack's ready. I've planted the thumper."
We could be lost forever in this hellplace , she thought. And no one to know .
The night wind spread sand runnels that grated across her face, bringing the smell of cinnamon: a shower of odors in the dark.
"Smell that," Paul said.
"I can smell it even through the filter," she said. "Riches. But will it buy water?" She pointed across the basin. "There are no artificial lights across there."
"Fremen would be hidden in a sietch behind those rocks," he said.
A sill of silver pushed above the horizon to their right: the first moon. It lifted into view, the hand pattern plain on its face. Jessica studied the white-silver of sand exposed in the light.
"I planted the thumper in the deepest part of the crevasse," Paul said. "Whenever I light its candle it'll give us about thirty minutes."
"Thirty minutes?"
"Before it starts calling . . . a . . . worm."
"Oh. I'm ready to go."
He slipped away from her side and she heard his progress back up their fissure.
The night is a tunnel , she thought, a hole into tomorrow . . . if we're to have a tomorrow . She shook her head. Why must I be so morbid? I was trained better than that!
Paul returned, took up the pack, led the way down to the first spreading dune where he stopped and listened as his mother came up behind him. He heard her soft progress and the cold single-grain dribbles of sound - the desert's own code spelling out its measure of safety.
"We must walk without rhythm," Paul said and he called up memory of men walking the sand . . . both prescient memory and real memory.
"Watch how I do it," he said. "This is how Fremen walk the sand."
He stepped out onto the windward face of the dune, following the curve of it, moved with a dragging pace.
Jessica studied his progress for ten steps, followed, imitating him. She saw the sense of it: they must sound like the natural shifting of sand . . . like the wind. But muscles protested this unnatural, broken pattern: Step . . . drag . . . drag . . . step . . . step . . . wait . . . drag . . . step . . .
Time stretched out around them. The rock face ahead seemed to grow no nearer. The one behind still towered high.
"Lump! Lump! Lump! Lump!"
It was a drumming from the cliff behind.
"The thumper," Paul hissed.
Its pounding continued and they found difficulty avoiding the rhythm of it in their stride.
"Lump . . . lump . . . lump . . . lump . . ."
They moved in a moonlit bowl punctured by that hollowed thumping. Down and up through spilling dunes: step . . .drag . . . wait . . . step . . . Across pea sand that rolled under their feet: drag . . . wait . . . step . . .
And all the while their ears searched for a special hissing.
The sound, when it came, started so low that their own dragging passage masked it. But it grew . . . louder and louder . . . out of the west.
"Lump . . . lump . . . lump . . . lump . . . " drummed the thumper.
The hissing approach spread across the night behind them. They turned their heads as they walked, saw the mound of the coursing worm.
"Keep moving," Paul whispered. "Don't look back."
A grating sound of fury exploded from the rock shadows they had left. It was a flailing avalanche of noise.
"Keep moving," Paul repeating.
He saw that they had reached an unmarked point where the two rock faces - the one ahead and the one behind - appeared equally remote.
And still behind them, that whipping, frenzied tearing of rocks dominated the night.
They moved on and on and on . . . Muscles reached a stage of mechanical aching that seemed to stretch out indefinitely, but Paul saw that the beckoning, escarpment ahead of them had climbed higher.
Jessica moved in a void of concentration, aware that the pressure of her will alone kept her walking. Dryness ached in her mouth, but the sounds behind drove away all hope of stopping for a sip from her stillsuit's catchpockets.
"Lump . . . lump . . . "
Renewed frenzy erupted from the distant cliff, drowning out the thumper.
Silence!
"Faster," Paul whispered.
She nodded, knowing he did not see the gesture, but needing the action to tell herself that it was necessary to demand even more from muscles that already were being taxed to their limits - the unnatural movement . . .
The rock face of safety ahead of them climbed into the stars, and Paul saw a plane of flat sand stretching out at the base. He stepped onto it, stumbled in his fatigue, righted himself with an involuntary out-thrusting of a foot.
