The air stopped quivering.
Silence!
The rocket men leaned and listened.
"Captain, did you hear it?"
"No."
"Like a wave, sir. On the sea bottom! I thought I saw something. Over there. A black wave. Big. Running at us."
"You were mistaken."
"There, sir!"
"What?"
"See it? There! The city! Way over! That green city near the lake! It's splitting in half. It's falling!"
The men squinted and shuffled forward.
Smith stood trembling among them. He put his hand to his head as if to find a thought there. "I remember. Yes, now I do. A long time back. When I was a child. A book I read. A story. Oz, I think it was. Yes, Oz. The Emerald City of Oz . . ."
"Oz?"
"Yes, Oz, that's what it was. I saw it just now, like in the story. I saw it fall."
"Smith!"
"Yes, sir?"
"Report to the ship's doctor."
"Yes, sir!" A brisk salute.
"Be careful."
The men tiptoed, guns alert, beyond the ship's aseptic light to gaze at the long sea and the low hills.
"Why," whispered Smith, disappointed, "there's no one here at all, is there? No one here at all."
The wind blew sand over his shoes, whining.
HERE THERE BE TYGERS
"You have to beat a planet at its own game," said Chatter-ton. "Get in and rip it up, kill its snakes, poison its animals, dam its rivers, sow its fields, depollinate its air, mine it, nail it down, hack away at it, and get the blazes out from under when you have what you want. Otherwise, a planet will fix you good. You can't trust planets. They're bound to be different, bound to be bad, bound to be out to get you, especially this far out, a billion miles from nowhere, so you get them first. Tear their skin off, I say. Drag out the minerals and run away before the nightmare world explodes in your face. That's the way to treat them."
The rocket ship sank down toward planet 7 of star system 84. They had traveled millions upon millions of miles; Earth was far away, her system and her sun forgotten, her system settled and investigated and profited on, and other systems rummaged through and milked and tidied up, and now the rockets of these tiny men from an impossibly remote planet were probing out to far universes. In a few months, a few years, they could travel anywhere, for the speed of their rocket was the speed of a god, and now for the ten-thousandth time one of the rockets of the far-circling hunt was feathering down toward an alien world.
"No," said Captain Forester. "I have too much respect for other worlds to treat them the way you want to, Chatterton. It's not my business to rape or ruin, anyway, thank God. I'm glad I'm just a rocket man. You're the anthropologist-mineralogist. Go ahead, do your mining and ripping and scraping. I'll just watch. I'll just go around looking at this new world, whatever it is, however it seems. I like to look. All rocket men are lookers or they wouldn't be rocket men. You like to smell new airs, if you're a rocket man, and see new colors and new people if there are new people to see, and new oceans and islands."
"Take your gun along," said Chatterton.
"In my holster," said Forester.
They turned to the port together and saw the green world rising to meet their ship. "I wonder what it thinks of us?" said Forester.
"It won't like me," said Chatterton. "I'll see to it it won't like me. And I don't care, you know, I'm out for the money. Land us over there, will you, Capt
