t gathered for the final spring, its terrible legs tensing perceptibly—a creature out of a nightmare. Garth Howard tried to shriek out a warning, but Hagendorff was holding his throat too well. He could only struggle weakly and nod toward the horror beyond; but the message did not get across to the giant.

Then the tarantula sprang again.

For a moment it seemed to hover on Hagendorff's upturned back. When it floated down, its ragged legs cradled over him, and the egg-shaped body squatted on his back....

Garth felt his frayed nerves and senses going. A hairy leg was touching him, chilling his flesh. Above him, the giant was thrashing impotently, and he found his neck free of the awful grip.

He wormed free. He was hardly conscious of reaching up and unlocking the door, and closing it tightly again as he stumbled forth. Later, it seemed that it was in a dream that he ran wildly into the splendid sunlight outside and down the winding trail. It was only by a tremendous effort that he kept his senses long enough to shove the rowboat out from the beach and hop in.

He never started the motor. All that he had seen and suffered on the island of horror overcame him too soon, and he pitched down in a limp, unconscious heap....


nd so it was, that, the next morning, the two harbor policemen found a rowboat with mysterious cargo floating silently down the Detroit River. So it was that some time later a launch with three local officers churned up to the solitary island, and that gunshots echoed in the gloom of a hushed laboratory room, and a man's white-faced body was carried from the cabin where he had made his one great treacherous effort to steal another's fame.
