g Rogans that lay as though
paralyzed on the metal paving, crawled equal thousands of Greca's
enslaved people. Their eyes flamed with fanatic hate. And
methodically--not knowing what had caused their loathed masters to be
stricken helpless, and not caring as long as they _were_ helpless--the
slaves were seeking out the shock-tubes that here and there had fallen
from the clutch of Rogan guards. Already many had found them; and
everywhere gangling, slimy bodies were melting in oily black smoke
that almost instantly vanished in thin air.

As it was in these streets and in the great square in the center of
which rested the Earthmen's ship, just so, they knew, was it being

language of mind or tongue for its complete expression.

"Will you come to Earth with me, Greca, and stay by my side till we
return to set your people in power again?"

Greca shook her head, slowly, reluctantly. "My people need leaders
