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.
