Moon, a single Aircar, whose
gleaming gray side was marked with queer crimson splashes, broke free to
pursue Jaska!

She fled at top speed, yet the Aircar was gaining, proof that the Moon
had developed speed greater than Earth had attained.

"But why," queried Sarka, "does she draw no nearer?"

"Great God!" ejaculated Sarka the Second, after a brief examination of
certain chartographs beside his Micro-Telescope. "We are moving away
from the Moon! Something is forcing us away! The people of the Moon have
something whose nature we do not know, capable of forcing them away from
us--while they pull our people toward them! You see? If they pulled us
toward them, we could overthrow them, for we outnumber them perhaps
thousands to one; but if they force themselves away faster than the Gens
of Dalis, if defeated, can follow us, they can destroy, or capture, the
Gens at their leisure!"

Suddenly, out of the Earth, past the all-seeing eyes of the
Micro-Telescopes, swept a new myriad. Men in white, wearing the Red Lily
of the House of Cleric! Cleric was sending out men to rescue Jaska from
the Aircar which pursued her! But would Jaska or these who went forth
to fetch her ever be able again to attain landing place upon the Earth!

It looked doubtful.

Even as Sarka asked himself this question fresh Aircars shot from the
rims of Moon craters, rushing outward to add their weight in the battle
against the Gens of Dalis. The Gens of Dalis was doomed!

In the mind of Sarka the Second there still loomed a hellish doubt that
would not down.

The men of Cleric were surrounding Jaska now, protecting her with their
lives against the tentacles of that lone Aircar splashed with
crimson--and all were flying a losing race with the Earth, which was
still being forced outward from the Moon!
