From all sides, from all directions, from other craters which these two had not even seen, came scores and hundreds of the monster cars!

They had beaten Luar and Dalis but for a moment, then! Now, at her command, the countless other aircars were coming in to head them off, to fight them back to the surface of the Moon. It would be a race against time, and against death. But of at least a dozen of the aircars, Sarka was master, and he did not fear the issue. That strange exaltation which the white flames had given him filled him with a confidence that nothing could shake.

He shot a thought at the gleaming cube in the forepeak.

"Faster! Faster! There is no limit to your speed! Faster! Faster! Even faster!"

Instantly the Moon seemed literally to drop away beneath the dozen aircars which carried the Radiant People, while the aircars of Luar and of Dalis fell hopelessly behind.

Sure that they would win in this race now, since he was just beginning to realize the vastness of his power—the all-encompassing, all-mastering power of the human mind and will, which the white flames of the Moon had made almost god-like—Sarka turned his eyes toward a coldly gleaming sphere in the star-spangled heavens ahead.


t was the Earth, and it seemed ringed in flames! From its edges there seemed to shoot long streamers of yellow or golden flames, which broke into sunlike pinwheels of radiance at their tips. Something, there on the precious Earth, was decidedly wrong!

Instantly, telepathically, he sought to gain mental contact with his father.
