Damis
watched the ground below them.

"Look, Lura!" he cried.

They swept over the site of the palace. The black ray was no longer
playing on it, but the whole palace glistened like crystal.

"What is it?" she asked.

"Frost!" he shouted. "The Martian weapon did its work well. Everything
in that palace is frozen. In the name of Tubain!"

The Jovian ejaculation had burst from his lips, unbidden, at the sight
which met his gaze. Racing over the land was a solid wall of water,
hundreds of feet high and moving with enormous speed. On toward the
palace it swept. Below they could see the Earthmen on the hill striving
to fly, but there was no place of safety. The oncoming wall of water was
higher by a hundred feet than the top of the hill and it was the highest
bit of land for many miles.

Nearer and nearer came the water until with a roar and a crash which
they could plainly hear in the crippled space ship, it swept over the
hill and the palace, burying them under a hundred feet of brine.

"Father!" cried Lura in anguish.

Damis made his way across the ship and folded her in his arms.

"He was chosen as one of the lives needed to buy the freedom of the
Earth," he murmured to her. "It is hard, for I loved him as a father;
but it was the end which he would have chosen. He died at the head of
his followers battling for freedom."

"What happened, Damis?" asked Lura an hour later as she looked down on
the seething tumult of water under them.

"As nearly as I can figure out, the Jovian fleet approached the palace
from the west at a low elevation. In order to destroy them, we could not
use the Martian weapon normal to the Earth's surface as they commanded
us, but were forced to use it tangentially. The enormous counter
reaction to the stream of force of almost incredible intensity which was
shot at Tubain's flyers, had to be absorbed in some way. The weapon
could not take it up as it was anchored to the center of gravity of the
earth. As a result, the force was translated into one of increased
rotation. The Earth must be spinning on its axis at fully twice its
former rate. Both the air and the water had too much inertia to follow
the accelerated motion of the land, so the wind blew a gale and the
oceans left their beds and swept over the land. Everything must have
been swept to destruction before this flood."

"And all our labor and sacrifice has been useless," c
