The banker put down his fork, spoke in an angry voice: "It's said that the Fremen scum drink the blood of their dead."
Kynes shook his head, spoke in a lecturing tone: "Not the blood, sir. But all of a man's water, ultimately, belongs to his people - to his tribe. It's a necessity when you live near the Great Flat. All water's precious there, and the human body is composed of some seventy per cent water by weight. A dead man, surely, no longer requires that water."
The banker put both hands against the table beside his plate, and Jessica thought he was going to push himself back, leave in a rage.
Kynes looked at Jessica. "Forgive me, my Lady, for elaborating on such an ugly subject at table, but you were being told falsehood and it needed clarifying."
"You've associated so long with Fremen that you've lost all sensibilities," the banker rasped.
Kynes looked at him calmly, studied the pale, trembling face. "Are you challenging me, sir?"
The banker froze. He swallowed, spoke stiffly: "Of course not. I'd not so insult our host and hostess."
Jessica heard the fear in the man's voice, saw it in his face, in his breathing, in the pulse of a vein at his temple. The man was terrified of Kynes!
"Our host and hostess are quite capable of deciding for themselves when they've been insulted," Kynes said. "They're brave people who understand defense of honor. We all may attest to their courage by the fact that they are here . . . now . . . on Arrakis."
Jessica saw that Leto was enjoying this. Most of the others were not. People all around the table sat poised for flight, hands out of sight under the table. Two notable exceptions were Bewt, who was openly smiling at the banker's discomfiture, and the smuggler, Tuek, who appeared to be watching Kynes for a cue. Jessica saw that Paul was looking at Kynes in admiration.
"Well?" Kynes said.
"I meant no offense," the banker muttered. "If offense was taken, please accept my apologies."
"Freely given, freely accepted," Kynes said. He smiled at Jessica, resumed eating as though nothing had happened.
Jessica saw that the smuggler, too, had relaxed. She marked this: the man had shown every aspect of an aide ready to leap to Kynes' assistance. There existed an accord of some sort between Kynes and Tuek.
Leto toyed with a fork, looked speculatively at Kynes. The Geologist's manner indicated a change in attitude toward the House of Atreides. Kynes had seemed colder on their trip over the desert.
Jessica signaled for another course of food and drink. Servants appeared with langues de lapins de garenne - red wine and a sauce of mushroom-yeast on the side.
Slowly, the dinner conversation resumed, but Jessica heard the agitation in it, the brittle quality, saw that the banker ate in sullen silence. Kynes would have killed him without hesitating , she thought. And she realized that there was an offhand attitude toward killing in Kynes' manner. He was a casual killer, and she guessed that this was a Fremen quality.
Jessica turned to the stillsuit manufacturer on her left, said: "I find myself continually amazed by the importance of water on Arrakis."
"Very important," he agreed. "What is this dish? It's delicious."
"Tongues of wild rabbit in a special sauce," she said. "A very old recipe."
"I must have that recipe," the man said.
She nodded. "I'll see that you get it."
Kynes looked at Jessica, said: "The newcomer to Arrakis frequently underestimates the importance of water here. You are dealing, you see, with the Law of the Minimum."
She heard the testing quality in his voice, said, "Growth is limited by that necessity which is present in the least amount. And, naturally, the least favorable condition controls the growth rate."
"It's rare to find members of a Great House aware of planetological problems," Kynes said. "Water is the least favorable condition for life on Arrakis. And remember that growth itself can produce unfavorable conditions unless treated with extreme care."
Jessica sensed a hidden message in Kynes' words, but knew she was missing it. "Growth," she said. "Do you mean Arrakis can have an orderly cycle of water to sustain human life under more favorable conditions?"
"Impossible!" the water magnate barked.
Jessica turned her attention to Bewt. "Impossible?"
"Impossible on Arrakis," he said. "Don't listen to this dreamer. All the laboratory evidence is against him."
Kynes looked at Bewt, and Jessica noted that the other conversations around the table had stopped while people concentrated on this new interchange.
"Laboratory evidence tends to blind us to a very simple fact," Kynes said. "That fact is this: we are dealing here with matters that originated and exist out-of-doors where plants and animals carry on their normal existence."
"Normal!" Bewt snorted. "Nothing about Arrakis is normal!"
"Quite the contrary," Kynes said. "Certain harmonies could be set up here along self-sustaining lines. You merely have to understand the limits of the planet and the pressures upon it."
"It'll never be done," Bewt said.
The Duke came to a sudden realization, placing the point where Kynes' attitude had changed - it had been when Jessica had spoken of holding the conservatory plants in trust for Arrakis.
"What would it take to set up the self-sustaining system, Doctor Kynes?" Leto asked.
"If we can get three per cent of the green plant element on Arrakis involved in forming carbon compounds as foodstuffs, we've started the cyclic system," Kynes said.
