His cheek slumped back against the hot sand, and he smelled the burned rock odor beneath the pre-spice gasses. From some corner of logic in his mind, a thought formed:
"To the working planetologist, his most important tool is human beings," his father said. "You must cultivate ecological, literacy among the people. That's why I've created this entirely new form of ecological notation."
He began to feel cool, but that corner of logic in his mind told him:
His fingers clawed feebly at the sand.
"The presence of moisture in the air helps prevent too-rapid evaporation from living bodies," his father said.
He tried to think of moisture in the air—grass covering this dune... open water somewhere beneath him, a long qanat flowing with water open to the sky except in text illustrations. Open water... irrigation water... it took five thousand cubic meters of water to irrigate one hectare of land per growing season, he remembered.
"Our first goal on Arrakis," his father said, "is grassland provinces. We will start with these mutated poverty grasses. When we have moisture locked in grasslands, we'll move on to start upland forests, then a few open bodies of water—small at first—and situated along lines of prevailing winds with windtrap moisture precipitators spaced in the lines to recapture what the wind steals. We must create a true sirocco—a moist wind—but we will never get away from the necessity for windtraps."
"You will die, too," his father said, "if you don't get off the bubble that's forming right now deep underneath you. It's there and you know it. You can smell the pre-spice gasses. You know the little makers are beginning to lose some of their water into the mass."
The thought of that water beneath him was maddening. He imagined it now—sealed off in strata of porous rock by the leathery half-plant, half-animal little makers—and the thin rupture that was pouring a cool stream of clearest, pure, liquid, soothing water into...
He inhaled, smelling the rank sweetness. The odor was much richer around him than it had been.
Kynes pushed himself to his knees, heard a bird screech, the hurried flapping of wings.
"Movement across the landscape is a necessity for animal life," his father said. "Nomad peoples follow the same necessity. Lines of movement adjust to physical needs for water, food, minerals. We must control this movement now, align it for our purposes."
"Shut up, old man," Kynes muttered.
"We must do a thing on Arrakis never before attempted for an entire planet," his father said. "We must use man as a constructive ecological force—inserting adapted terraform life: a plant here, an animal there, a man in that place—to transform the water cycle, to build a new kind of landscape."
"Shut up!" Kynes croaked.
"It was lines of movement that gave us the first clue to the relationship between worms and spice," his father said.
He could feel frustration sapping what little strength remained to him. Water so near—only a hundred meters or so beneath him; a worm sure to come, but no way to trap it on the surface and use it.
Kynes pitched forward onto the sand, returning to the shallow depression his movements had defined. He felt sand hot against his left cheek, but the sensation was remote.
