Suddenly the two priests began to pirouette, and as they whirled more and more rapidly, their huge glowing eyes made phosphorescent circles in the gloom like those that had so alarmed and fascinated us in the cavern. They gyrated round the ring of worshipers with accelerated speed, and all those poor creatures fell under the fascination and drooped with heads to the ground. Now for the first time I caught sight of an oblong object rising a couple of feet above the ground in the center of the circle. I was wondering what it might be when the spinning priests, who had gradually drawn closer to the ring of worshipers, dived into the circle, and, catching each a native in his arms, ran with their captives to the curious object that I have just described.

"It's a sacrificial stone!" exclaimed Edmund. "They're going to kill them as an offering to the earth and her child the moon."

I was frozen with horror at the sight, but just as the second priest reached the altar, where the first victim had already been pinned with the sharp point of the sacrificial staff, his captive, suddenly recovering his senses, and terrified by the awful fate confronting him, uttered a cry, wrenched himself loose, and, running like the wind, leaped over the circle and disappeared in the darkness. The fugitive passed close by us, and Jack shouted as he darted past:

"Good boy!"

The enraged priest was after him like lightning, and as he came near us his awful eyes seemed to emit actual flames. But the runner had vanished. Without an instant's hesitation the priest shot out his great arm and caught me by the throat! In another second I felt myself carried in a bound, as if a tiger had seized me, over the drooping heads of the worshipers and toward the horrible altar.

CHAPTER V

OFF FOR THE SUN LANDS

Dreadful as the moment was, I did not lose my senses. On the contrary, my mind was fearfully clear and active. There was not a horror that I missed. The strength and agility of my captor were astounding. I could no more have struggled with him than with a lion. Only one thing flashed upon me to do; I yelled with all the strength of my lungs. But they had become accustomed to our voices now, and the maddened creature was so intent upon his fell purpose that a cannon-shot would not have diverted him from it.

He got me to the altar, where the preceding victim already lay with his heart torn out, and, pressing me against it with all his bestial force, raised the pointed staff to transfix me. With dying eyes I saw the earth gleaming, magnificent, directly over my head, and my heart bounded with unreasoning hope at the sight. It was my mother planet, powerful to save!

All this passed in a second, while the dreadful spear was poised for its work. Even in that fraction of time I noticed the bunching muscles of the murderer's hairy arm, and then I pressed my eyes shut.
