Another moment, perhaps, and it would have been too late to test his plan. He doubted that he could hold out until the reptile returned again. Everything, therefore, depended upon success at the first cast of the die--his life and Dangar's. Quickly he gathered his nervous forces under control. Again he was cool, collected. He loosened his pistol in its holster and took a new grip on the strap.

The Trodon crossed the pit, bearing the paralyzed victim to its place in the lethal circle. It placed one great hind paw in the open noose. Von Horst sent a running wave of the rope across the floor that lifted the noose up the creature's leg above the ankle; then he gave a quick jerk. The noose tightened a little. Was it enough?

Would it hold? As he had expected, the creature paid no attention to the strap. It appeared not to feel it, and von Horst was quite sure that it did not. So low was its nervous organization, he believed, that only a sharp blow on the leg would have carried any sensation to the brain.

After it had deposited the latest victim, the reptile turned toward the center of the pit, leaped into the air and fluttered aloft. Von Horst held his breath. Would the noose be shaken loose? Heaven forbid. It held. Von Horst leaped to his feet and ran toward the center of the pit, his pistol cocked and ready in his hand; and as the Trodon rose through the mouth of the crater and cleared the top of the hill, the man fired three shots in rapid succession.

He did not need the horrid screams of the wounded creature to tell him that his aim had been true, for he saw the great reptile careen in air and plunge from sight beyond the rim of the crater; then von Horst leaped for the end of the strap, seized it, braced himself, and waited.

There was danger that the body of the creature, tumbling down the steep side of the cone-shaped hill, might not come to rest before it jerked the strap from his hands; so he quickly wound it around his body and hurriedly made it fast. He might be killed; but he wouldn't lose his strap or jeopardize this, his last chance of escape from the pit. For a moment the strap played out rapidly from the coil; then it stopped. Either the body of the Trodon had come to rest or the noose had slipped from the hind leg. Which?

Von Horst pulled on the strap fearfully. Soon it tautened; then he knew that it was still attached to the creature. A vague doubt assailed him as to whether the Trodon had been killed or not. He knew how tenacious of life such creatures might be. Suppose it were not dead? What dire possibilities such an event might entail!

The man tugged on the strap. It did not give. Then he swung on it with all his weight. It remained as before. Still, clinging to the loose end, he crossed the pit to Dangar, who was gazing at him wide-eyed with astonishment.

"You should have been a Sarian," said Dangar with admiration.

Von Horst smiled. "Come," he said. "Now for you." He stooped and lifted the Pellucidarian from the ground and carried him to the center of the pit beneath the crater mouth; then he made the loose end of the strap secure about his body beneath the arms.

"What are you going to do?" asked Dangar.

"Just now I am going to make the inner world a little safer for thin-skinned animals," replied Von Horst.

He went to the side of the pit, commenced breaking the eggs with the butt of his pistol.
