nd nodded.

"Of course, of course. You have five bodies right here on the
asteroid. Yes."

"At least," continued Carse levelly, "I do not regret having to use
the bodies of your men. They are no longer human: they are not men:
they are in effect but machines of your making, Dr. Ku."

"Quite. Quite."

"I suppose you find it an unpleasant thought, to have to be the means
of re-making them into whole, normal human beings?"

"On the contrary," breathed the Eurasian, "you inspire a very pleasant
thought in my brain, Captain Carse--though I must confess it is not
exactly the thought you mention." A smile, veiled by the smoke of the
cigarro, appeared on his lips.

The Hawk looked at him closely: the words had a hidden meaning, and it
was clear he was not intended to miss the implied threat. But what was
Ku Sui's thought? Back in his mind an anxiety grew, indefinite, vague
and devilish.

And that vague anxiety was still with him when, fifty-seven minutes
later, the asteroid returned from its inverted U-flight, slowed in its
hurtling drop from space and hovered directly over the secret, hidden

CHAPTER VIII

_White's Brain--Yellow's Head_

To Friday it was a bad mistake to reveal the location of the
laboratory to Dr. Ku Sui. From him above all men had that location up
to now been kept. Just a few days before, Hawk Carse had risked his
life to preserve the secret. And yet now, deliberately, he was showing
it to the Eurasian!

Nervously, Friday watched him, and he saw that his eyes were alive
with interest as they scanned the visi-screen. It was too much for the
Negro.

"Captain Carse," he whispered, coming close to the adventurer, "look,
suh--he's seein' it all! Shouldn't I blindfold him?"

Carse shook his head, but turned to Dr. Ku, where he sat bound in the
chair scrutinizing the visi-screen.

"Yes, Doctor," he said, "there it is--what you have searched for so
long--the refuge and the laboratory of Eliot Leithgow."

"There, Captain?" murmured the Eurasian. "I see nothing!"

And true, the visi-screen showed nothing but a hill, a lake, a swamp,
and the distant, surrounding jungle.

That spot on Satellite III had been most carefully chosen by the
Master Scientist and Carse as best suiting their needs. It lay at
least a thousand miles--a thousand miles of ugly, primeval
jungle--from the nearest unfriendly isuan ranch, and was diametrically
opposite Port
