ed at the nearest ship, and ripped out
that ray that burned it--and quivered into death. It quivered, then
quickly faded into mist, a haze, and was gone!

A last awful thing--a thing they had not noticed as all eyes watched
that Thing--was standing by the rent in the Sphere now, the gigantic
Thessian, with leering, bestial jaws, enormous, squat limbs, the webbed
fingers and toes, and the heavy torso of his race, grinning at them. In
one hand was a thing--and his jaws munched. Thett's men stared in horror
as they recognized that thing in his hand--a Thessian body! He grinned
happily and reached for a battleship--a ray burned him. He howled, and
leaped into their midst.

Then the Thessians went mad. All fought, and they fought each other,
rays of all sorts, their moleculars and their cosmics, while in their
midst the Giant howled his glee, and laughed and laughed--

Eventually it was over, and the last limping Thessian ship drove itself
crazily against the wreck of its last enemy. And only wreckage was left.

"Lord, Arcot! Why in the Universe did you do that--and how did you
conceive those horrors?" asked Morey, more than a little amazed at the
tactics Arcot had displayed.

Arcot shook himself, and disconnected his controls. "Why--why I don't
know. I don't know what made me do that, I'm sure. I never imagined
anything like that dragon thing--how did--"

His keen eyes fixed themselves suddenly on Zezdon Fentes, and their
tremendous hypnotic power beat down the resistance of the Ortolian's
trained mind. Arcot's mind opened for the others the thoughts of Zezdon
Fentes.

He had acted as a medium between the minds of the Thessians, and Arcot.
Taking the horror-ideas of the Thessians, he had imprinted them on
Arcot's mind while Arcot was at work with the controls. In Arcot's mind,
they had acted exactly as had the ideas that night on Earth, only here
the demonstration had been carried to the limit, and the horror ideas
were compounded to the utmost. The Thessians, highly developed minds
though they were, were not resistant and they had broken. The Allies,
with their different horror-ideas, had been but slightly affected.

"We will leave you on Ortol, Zezdon Fentes. We know you have done much,
and perhaps your own mind has given a bit. We hope you recover. I think
you agree with me, Zezdon Afthen and Inthel?" thought Arcot.

"We do, heartily, and are heartily sorry that one of our race has acted
in this way. Let us pro
