There was, Grant knew, no use of going on. He read the answer in Joe's eyes.
"You really think," said Joe and his words were terse and measured, "that I'd turn this over to you squalling humans?"
Grant shrugged in defeat. "I suppose not. I suppose I should have known. A man like you-"
"I," said Joe, "can use this thing myself."
He rose slowly, idly swung his foot, ploughing a furrow through the ant hill, toppling the smoking chimneys, burying the toiling carts.
With a cry, Grant leaped to his feet, blind anger gripping him, blind anger driving the hand that snatched out his gun.
"Hold it!" said Joe.
Grant's arm halted with the gun still pointing towards the ground.
"Take it easy, little man," said Joe. "I know you'd like to kill me, but I can't let you do it. For I have plans you see. And, after all, you wouldn't be killing me for the reason that you think."
"What difference would it make why I killed you?" rasped Grant. "You'd be dead, wouldn't you? You wouldn't be loose with Juwain's philosophy."
"But," Joe told him, almost gently, "that's not why you would kill me. You'd do it because you're sore at me for mussing up the ant hill."
"That might have been the reason first," said 'Grant. "But not now-"
"Don't try it," said Joe. "Before you ever pressed the trigger you'd be meat yourself."
Grant hesitated.
"If you think I'm bluffing," Joe taunted him, "go ahead and call me."
For a long moment the two stood face to face, the gun still pointing at the ground.
"Why can't you throw in with us?" asked Grant. "We need a man like you. You were the one that showed old Tom Webster how to build a space drive. The work you've done with ants-"
Joe was stepping forward, swiftly, and Grant heaved up the gun. He saw the fist coming at him, a hamlike, powerful fist that fairly whistled with its vicious speed.
A fist that was faster than his finger on the trigger.
Something wet and hot was rasping across Grant's face and he lifted a hand and tried to brush it off.
But it went on, licking across his face.
He opened his eyes and Nathaniel did a jig in front of them.
"You're all right," said Nathaniel. "I was so afraid-"
"Nathaniel!" croaked Grant. "What are you doing herw?"
"I ran away," Nathaniel told him. "I want to go with you."
Grant shook his head. "You can't go with me. I have far to go. I have a job to do."
He got to his hands and knees and felt along the ground. When his hand touched cold metal, he picked it up and slid it in the holster.
"I let him get away," he said, "and I can't let him go. I gave him something that belonged to all mankind and I can't let him use it."
"I can track," Nathaniel told him. "I track squirrels like everything."
"You have more important things to do than tracking,"
Grant told the dog. "You see, I found out something today. Got a glimpse of a certain trend – a trend that all mankind may follow. Not today nor to-morrow, nor even a thousand years from now. Maybe never, but it's a thing we can't overlook. Joe may be just a little farther along the path than the rest of us and we may be following faster than we think. We may all end up like Joe. And if that is what is happening, if that is where it all will end, you dogs have a job ahead of you."
Nathaniel stared up at him, worried wrinkles on his face.
"I don't understand," he pleaded. "You use words I can't make out."
"Look, Nathaniel. Men may not always be the way they are today. They may change. And, if they do, you have to carry on; you have to take the dream and keep it going. You'll have to pretend that you are men."
"Us dogs," Nathaniel pledged, "will do it."
"It won't come for thousands and thousands of years," said Grant. "You will have time to get ready. But you must know. You must pass the word along. You must not forget"
"I know," said Nathaniel. "Us dogs will tell the pups and the pups will tell their pups."
"That's the idea," said Grant.
He stooped and scratched Nathaniel's ear and the dog, tail wagging to a stop, stood and watched him climb the hill.
