quivering, primordial bog, and lay crouched over the controls for a long time before he moved.

He had made a mistake, he and de Terry; there weren't any doubts left at all. And there was ... there might be a way to right it.

He looked out at the Coal Measure forest. The fern trees were not the fern trees he had seen before; the machine had been moved in space. But the time, he knew was identically the same; trust the machine for that. He thought: I gave the world to the ants, right here. I can take it back. I can find the ants I buried and crush them underfoot ... or intercept myself before I bury them....

He got out of the machine, suddenly panicky. Urgency squinted his eyes as he peered around him.

Death had been very close in the ant city; the reaction still left Gordy limp. And was he safe here? He remembered the violent animal scream he had heard before, and shuddered at the thought of furnishing a casual meal to some dinosaur ... while the ant queens lived safely to produce their horrid young.

A gleam of metal through the fern trees made his heart leap. Burnished metal here could mean but one thing—the machine!

Around a clump of fern trees, their bases covered with thick club mosses, he ran, and saw the machine ahead. He raced toward it—then came to a sudden stop, slipping on the damp ground.

For there were two machines in sight.

The farther machine was his own, and through the screening mosses he could see two figures standing in it, his own and de Terry's.

But the nearer was a larger machine, and a strange design.

And from it came a hastening mob—not a mob of men, but of black insect shapes racing toward him.

Of course, thought Gordy, as he turned hopelessly to run—of course, the ants had infinite time to work in. Time enough to build a machine after the pattern of his own—and time to realize what they had to do to him, to insure their own race safety.

Gordy stumbled, and the first of the black things was upon him.

As his panicky lungs filled with air for the last time, Gordy knew what animal had screamed in the depths of the Coal Measure forest.

He filled his lungs for one last scream.
