Lorill Hastur said, “What about it, Valdir? You know something of atomic structures. Is it practical at all?”
The men who had slept in the meadow were collecting their tools now, forming in groups, getting their orders for the day’s work. Larry looked at the forest edge. How green it looked. Yet above it rose the blanket of smoke and the omnipresent dull roar of the fire. Valdir turned, too, and looked at the cloud that hung over the burning woods.
He said, “Fire throws off the same gas as breath. There must be an enormous quantity of carbon dioxide going off into the air.”
“We can move it into the cold of the outer sky,” Lorill Hastur said. “That’s easy enough. And from there, if it falls on the clouds—”
“There’s no time to waste,” the woman said. Her eyes were closed, her voice remote, as she added, “A fire-storm has broken out on the far side of the forest, and the main blaze is racing toward the villages there. The fire-lines will never contain it. Rain is the only hope. There is enough moisture in those clouds to kill the fire—if we could only get it out of them.”
“We can try,” Valdir said. The three of them went into one of those intent silences again, the very air between their still forms seeming to tremble with invisible force.
Larry looked at Kennard. “Do you know what they’re going to do? How can they—?”
“They can teleport the gas above the clouds,” Kennard said. “If the cold can freeze it—”
Larry was becoming a little hardened to these curious powers now. If telepathy was possible, teleportation was only a minor step—
“If they can teleport, why don’t they just teleport enough water from a river, or something, to put out the fire?”
“Too much weight involved,” Kennard said gravely. “Even the clouds—they didn’t move the clouds themselves, just enough air to create a wind to move them here.” He fell silent, his eyes on his father, and when Larry started to speak, motioned him, impatiently, to silence.
The silence in the dawnlit meadow deepened; there was no sound at all, except for the distant, indistinct sound of the fire. The clouded sky seemed to darken, grow thick and dreary. Larry watched a group of men moving away toward the fire-lines; he and Kennard should have been with them. And they stood here, waiting, watching the three telepaths—
Abruptly there was a great WHOOSH from the distant fire; Larry, whirling round, saw a tremendous uprushing billow of smoke and flame, and seemed to feel, rather than hear, the wild roaring sound. Then silence again, hushed, tense and deep.
Above his head the clouds moved, writhed, seeming to form and reform into tossing shapes and worms of moisture; they curdled, coalesed, the sky darkened and darkened as the cloud-gray deepened.
Then the sky and cloud-layer suddenly dissolved—that was the only way Larry could describe it, afterward—and flowed into dark, thick lines of teeming, pouring rain. The burning forest sizzled, crackled in a sort of desperation. Great thick clouds of smoke and steam and soot billowed upward, and a rushing wind flung great sparks upward. Larry was soaked through in a moment, before the rain localized itself, pouring heavily down over the forest, but leaving the meadow untouched except by the brief spit of rain. The flames, visible over the treetops, sank and died beneath the upsurge of steam and smoke. The hissing sound grew louder, roared, then dimmed and was still.
The rain stopped.
Soaked, shivering, Larry stared in blank wonder at Valdir and the two gray-clad telepaths. They had cornered the clouds; they had harnessed the very force of the rain to combat the fire!
Valdir beckoned to the boys. They walked across the damp grass, Larry still a little dazed. He had boasted of Terran science; could it match this?
“That’s over with, at least,” Valdir said, in a tone of profound relief. “Larry, I wanted to thank you; without what you told us, none of us would have known how to do that. I hardly know how to thank you.”
It was more confusing than ever. These men had forces and powers undreamed of by science—and yet they were ignorant of a simple notion like cloud-seeding! Because he could not have spoken without revealing that mixture of awe, mingled with surprise at the incompleteness of the knowledge, Larry was silent. Valdir turned to Lorill Hastur and said, “Now you can see my point, perhaps! Without their knowledge—”
