It was May when John de Terry appeared. Gordy was spading his garden. “Give me something to eat,” said the voice behind Gordy’s back.
Salva Gordy turned around and saw the small, dirty man who spoke. He rubbed his mouth with the back of his hand. “You’ll have to work for it,” he said.
“All right.” The newcomer set down his pack. “My name is John de Terry. I used to live here in Detroit.”
Salva Gordy said, “So did I.”
Gordy fed the man, and accepted a cigarette from him after they had eaten. The first puffs made him lightheaded—it had been that long since he’d smoked—and through the smoke he looked at John de Terry amiably enough. Company would be all right, he thought. The pink mice had been company, of a sort—but it turned out that the mutation that made them hairless had also given them an appetite for meat. And after the morning when he had awakened to find tiny tooth-marks in his leg, he’d had to destroy them. And there had been no other animal since, nothing but the ants.
“Are you going to stay?” Gordy asked.
De Terry said, “If I can. What’s your name?” When Gordy told him, some of the animal look went out of his eyes, and wonder took its place. “Doctor Salva Gordy?” he asked. “Mathematics and physics in Pasadena?”
“Yes, I used to teach at Pasadena.”
“And I studied there.” John de Terry rubbed absently at his ruined clothes. “That was a long time ago. You didn’t know me; I majored in biology. But I knew you.”
Gordy stood up and carefully put out the stub of his cigarette. “It was too long ago,” he said. “I hardly remember. Shall we work in the garden now?”
Together they sweated in the spring sunlight that afternoon, and Gordy discovered that what had been hard work for one man went quickly enough for two. They worked clear to the edge of the plot before the sun reached the horizon. John de Terry stopped and leaned on his spade, panting.
He gestured to the rank growth beyond Gordy’s patch. “We can make a bigger garden,” he said. “Clear out that truck, and plant more food. We might even—” He stopped. Gordy was shaking his head.
“You can’t clear it out,” said Gordy. “It’s rank stuff, a sort of crabgrass with a particularly tough root. I can’t even cut it. It’s all around here, and it’s spreading.”
De Terry grimaced. “Mutation?”
“I think so. And look.” Gordy beckoned to the other man and led him to the very edge of the cleared area. He bent down, picked up something red and wriggling between his thumb and forefinger.
De Terry took it from his hand. “Another mutation?” He brought the thing close to his eyes. “It’s almost like an ant,” he said. “Except—well, the thorax is all wrong. And it’s soft-bodied.” He fell silent, examining the thing.
He said something under his breath, and threw the insect from him. “You wouldn’t have a microscope, I suppose? No—and yet, that thing is hard to believe. It’s an ant, but it doesn’t seem to have a tracheal breathing system at all. It’s something different.”
“Everything’s different,” Gordy said. He pointed to a couple of abandoned rows. “I had carrots there. At least, I thought they were carrots; when I tried to eat them they made me sick.” He sighed heavily. “Humanity has had its chance, John,” he said. “The atomic bomb wasn’t enough; we had to turn everything into a weapon. Even I, I made a weapon out of something that had nothing to do with war. And our weapons have blown up in our faces.”
De Terry grinned. “Maybe the ants will do better. It’s their turn now.”
“I wish it were.” Gordy stirred earth over the boiling entrance to an anthole and watched the insects in their consternation. “They’re too small, I’m afraid.”
“Why, no. These ants are different, Dr. Gordy. Insects have always been small because their breathing system is so poor. But these are mutated. I think—I think they actually have lungs. They could grow, Dr. Gordy. And if ants were the size of men … they’d rule the world.”
“Lunged ants!” Gordy’s eyes gleamed. “Perhaps they will rule the world, John. Perhaps when the human race finally blows itself up once and for all. …”
De Terry shook his head, and looked down again at his tattered, filthy clothes. “The next blowup is the last blowup,” he said. “The ants come too late, by millions and millions of years.”
He picked up his spade. “I’m hungry again, Dr. Gordy,” he said.
They went back to the house and, without conversation, they ate. Gordy was preoccupied, and de Terry was too new in the household to force him to talk.
It was sundown when they had finished, and Gordy moved slowly to light a lamp. Then he stopped.
“It’s your first night, John,” he said. “Come down cellar. We’ll start the generator and have real electric lights in your honor.”
De Terry followed the older man down a flight of stairs, groping in the dark. By candlelight they worked over a gasoline generator; it was stiff from disuse, but once it started it ran cleanly. “I salvaged it from my own,” Gordy explained. “The generator—and that.”
He swept an arm toward a corner of the basement. “I told you I invented a weapon,” he added. “That’s it.”
De Terry looked. It was as much like a cage as anything, he thought—the height of a man and almost cubical. “What does it do?” he asked.
For the first time in months, Salva Gordy smiled. “I can’t tell you in English,” he said. “And I doubt that you speak mathematics. The closest I can come is to say that it displaces temporal coordinates. Is that gibberish?”
“It is,” said de Terry. “What does it do?”
“Well, the War Department had a name for it—a name they borrowed from H. G. Wells. They called it a Time Machine.” He met de Terry’s shocked, bewildered stare calmly. “A time machine,” he repeated. “You see,
