Arrakis. I am steward of this land.”
He stumbled, fell sideways along the crusty surface of the windward face. His hands dug feebly into the sand.
He realized that he was semi-delirious, that he should dig himself into the sand, find the relatively cool underlayer and cover himself with it. But he could still smell the rank, semisweet esthers of a pre-spice pocket somewhere underneath this sand. He knew the peril within this fact more certainly than any other Fremen. If he could smell the pre-spice mass, that meant the gasses deep under the sand were nearing explosive pressure. He had to get away from here.
His hands made weak scrabbling motions along the dune face.
A thought spread across his mind—clear, distinct:
And he thought how strange it was that the mind, long fixed on a single track, could not get off that track. The Harkonnen troopers had left him here without water or stillsuit, thinking a worm would get him if the desert didn’t. They had thought it amusing to leave him alive to die by inches at the impersonal hands of his planet.
“The highest function of ecology is understanding consequences.”
The voice shocked him because he recognized it and knew the owner of it was dead. It was the voice of his father who had been planetologist here before him—his father long dead, killed in the cave-in at Plaster Basin.
“Got yourself into quite a fix here, Son,” his father said. “You should’ve known the consequences of trying to help the child of that Duke.”
The voice seemed to come from his right. Kynes scraped his face through sand, turning to look in that direction—nothing except a curving stretch of dune dancing with heat devils in the full glare of the sun.
“The more life there is within a system, the more niches there are for life,” his father said. And the voice came now from his left, from behind him.
“Life improves the capacity of the environment to sustain life,” his father said. “Life makes needed nutrients more readily available. It binds more energy into the system through the tremendous chemical interplay from organism to organism.”
Desert hawks, carrion-eaters in this land as were most wild creatures, began to circle over him. Kynes saw a shadow pass near his hand, forced his head farther around to look upward. The birds were a blurred patch on silver-blue sky—distant flecks of soot floating above him.
“We are generalists,” his father said. “You can’t draw neat lines around planet-wide problems. Planetology is a cut-and-fit science.”
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.
“The Arrakeen environment built itself into the evolutionary pattern of native life forms,” his father said. “How strange that so few people ever looked up from the spice long enough to wonder at the near-ideal nitrogen-oxygen-CO2 balance being maintained here in the absence of large areas of plant cover. The energy sphere of the planet is there to see and understand—a relentless process, but a process nonetheless. There is a gap in it? Then something occupies that gap. Science is made up of so many things that appear obvious after they
