She was on the porch, quick as a bird. The sunlight struck full upon her. She stood as someone on a stage, in a single revealing motion, come from the dark. Then, down the steps, she threw her hand to catch his.

A small boy pa.s.sing on the road below stopped, stared and, walking backward, moved out of sight, his eyes still wide.

"Why did he stare at me?" she said. "Am I beautiful?"

"Very beautiful."

"I need a mirror!"

"No, no, you don't."

"Will everyone in town see me beautiful? It's not just me thinking so, is it, or you pretending?"

"Beauty is what you are."

"Then I'm beautiful, for that's how I feel. Will everyone dance me tonight, will men fight for turns?"

"They will, one and all."

Down the path, in the sound of bees and stirring leaves, she stopped suddenly and looked into his face so like the summer sun.

"Oh, w.i.l.l.y, w.i.l.l.y, when it's all over and we come back here, will you be kind to me?"

He gazed deep into her eyes and touched her cheek with his fingers.

"Yes," he said gently. "I will be kind."

"I believe you," she said. "Oh, w.i.l.l.y, I believe."

And they ran down the path out of sight, leaving dust on the air and leaving the front door of the house wide and the shutters open and the windows up so the light of the sun could flash in with the birds come to build nests, raise families, and so petals of lovely summer flowers could blow like bridal showers through the long halls in a carpet and into the rooms and over the empty-but-waiting bed. And summer, with the breeze, changed the air in all the great s.p.a.ces of the house so it smelled like the Beginning or the first hour after the Beginning, when the world was new and nothing would ever change and no one would ever grow old.

Somewhere rabbits ran thumping like quick hearts in the forest.

Far off, a train hooted, rushing faster, faster, faster, toward the town.

ZERO HOUR.

OH, IT WAS TO BE SO JOLLY! What a game! Such excitement they hadn't known in years. The children catapulted this way and that across the green lawns, shouting at each other, holding hands, flying in circles, climbing trees, laughing. Overhead the rockets flew, and beetle cars whispered by on the streets, but the children played on. Such fun, such tremulous joy, such tumbling and hearty screaming.

Mink ran into the house, all dirt and sweat. For her seven years she was loud and strong and definite. Her mother, Mrs. Morris, hardly saw her as she yanked out drawers and rattled pans and tools into a large sack.

"Heavens, Mink, what's going on?"

"The most exciting game ever!" gasped Mink, pink-faced.

"Stop and get your breath," said the mother.

"No, I'm all right," gasped Mink. "Okay I take these things, Mom?"

"But don't dent them," said Mrs. Morris.

"Thank you, thank you!" cried Mink, and boom! she was gone, like a rocket.

Mrs. Morris surveyed the fleeing tot. "What's the name of the game?"

"Invasion!" said Mink. The door slammed.

In every yard on the street children brought out knives and forks and pokers and old stovepipes and can openers.

It was an interesting fact that this fury and bustle occurred only among the younger children. The older ones, those ten years and more, disdained the affair and marched scornfully off on hikes or played a more dignified version of hide-and-seek on their own.

Meanwhile, parents came and went in chromium beetles. Repairmen came to repair the vacuum elevators in houses, to fix fluttering television sets or hammer upon stubborn food-delivery tubes. The adult civilization pa.s.sed and repa.s.sed the busy youngsters, jealous of the fierce energy of the wild tots, tolerantly amused at their flourishings, longing to join in themselves.

"This and this and this," said Mink, instructing the others with their a.s.sorted spoons and wrenches. "Do that, and bring that over here. No! Here, ninny! Right. Now, get back while I fix this." Tongue in teeth, face wrinkled in thought. "Like that. See?"

"Yayyyy!" shouted the kids.

Twelve-year-old Joseph Connors ran up.

"Go away," said Mink straight at him.

"I wanna play," said Joseph.

"Can't!" said Mink.

"Why not?"

"You'd just make fun of us."

"Honest. I wouldn't."

"No. We know you. Go away or we'll kick you."

Another twelve-year-old boy whirred by on little motor skates. "Hey, Joe! Come on! Let them sissies play!"

Joseph showed reluctance and a certain wistfulness. "I want to play," he said.

"You're old," said Mink firmly.

"Not that old," said Joe sensibly.

"You'd only laugh and spoil the Invasion."

The boy on the motor skates made a rude lip noise. "Come on, Joe! Them and their fairies! Nuts!"

Joseph walked off slowly. He kept looking back, all down the block.

Mink was already busy again. She made a kind of apparatus with her gathered equipment. She had appointed another little girl with a pad and pencil to take down notes in painful slow scribbles. Their voices rose and fell in the warm sunlight.

All around them the city hummed. The streets were lined with good green and peaceful trees. Only the wind made a conflict across the city, across the country, across the continent. In a thousand other cities there were trees and children and avenues, businessmen in their quiet offices taping their voices or watching televisors. Rockets hovered like darning needles in the blue sky. There was the universal, quiet conceit and easiness of men accustomed to peace, quite certain there would never be trouble again. Arm in arm, men all over Earth were a united front. The perfect weapons were held in equal trust by all nations. A situation of incredibly beautiful balance had been brought about. There were no traitors among men. No unhappy ones, no disgruntled ones; therefore the world was based upon a stable ground. Sunlight illumined half the world and the trees drowsed in a tide of warm air.

Mink's mother, from her upstairs window, gazed down.

The children. She looked upon them and shook her head. Well, they'd eat well, sleep well, and be in school on Monday. Bless their vigorous little bodies. She listened.

Mink talked earnestly to someone near the rose bush-though there was no one there.

These odd children. And the little girl, what was her name? Anna? Anna took notes on a pad. First, Mink asked the rosebush a question, then called the answer to Anna.

"Triangle," said Mink.

"What's a tri," said Anna with difficulty, "angle?"

"Never mind," said Mink.

"How you spell it?" asked Anna.

"T-r-i-" spelled Mink slowly, then snapped, "Oh, spell it yourself!" She went on to other words. "Beam," she said.

"I haven't got tri," said Anna, "angle down yet!"

"Well, hurry, hurry!" cried Mink.

Mink's mother leaned out the upstairs window. "A-n-g-l-e," she spelled down at Anna.

"Oh, thanks, Mrs. Morris," said Anna.

"Certainly," said Mink's mother and withdrew, laughing, to dust the hall with an electro-duster magnet.

The voices wavered on the shimmery air. "Beam," said Anna. Fading.

"Four-nine-seven-A-and-B-and-X," said Mink, far away, seriously. "And a fork and a string and a-hex-hex-agony-hexagonal!"

At lunch Mink gulped milk at one toss and was at the door. Her mother slapped the table.

"You sit right back down," commanded Mrs. Morris. "Hot soup in a minute." She poked a red b.u.t.ton on the kitchen butler, and ten seconds later something landed with a b.u.mp in the rubber receiver. Mrs. Morris opened it, took out a can with a pair of aluminum holders, unsealed it with a flick, and poured hot soup into a bowl.

During all this Mink fidgeted. "Hurry, Mom! This is a matter of life and death! Aw-"

"I was the same way at your age. Always life and death. I know."

Mink banged away at the soup.

"Slow down," said Mom.

"Can't," said Mink. "Drill's waiting for me."

"Who's Drill? What a peculiar name," said Mom.

"You don't know him," said Mink.

"A new boy in the neighborhood?" asked Mom.

"He's new all right," said Mink. She started on her second bowl.

"Which one is Drill?" asked Mom.

"He's around," said Mink evasively. "You'll make fun. Everybody pokes fun. Gee, darn."

"Is Drill shy?"

"Yes. No. In a way. Gosh, Mom, I got to run if we want to have the Invasion!"

"Who's invading what?"

"Martians invading Earth. Well, not exactly Martians. They're-I don't know. From up." She pointed with her spoon.

"And inside," said Mom, touching Mink's feverish brow.

Mink rebelled. "You're laughing! You'll kill Drill and everybody."

"I didn't mean to," said Mom. "Drill's a Martian?"

"No. He's-well-maybe from Jupiter or Saturn or Venus. Anyway, he's had a hard time."

"I imagine." Mrs. Morris hid her mouth behind her hand.

"They couldn't figure a way to attack Earth."

"We're impregnable," said Mom in mock seriousness.

"That's the word Drill used! Impreg-That was the word, Mom."

"My, my, Drill's a brilliant little boy. Two-bit words."

"They couldn't figure a way to attack. Mom. Drill says-he says in order to make a good fight you got to have a new way of surprising people. That way you win. And he says also you got to have help from your enemy."

"A fifth column," said Mom.

"Yeah. That's what Drill said. And they couldn't figure a way to surprise Earth or get help."
