I'll keep in touch with you through the ethero-radio," he lifted his left arm exposing the watch-like instrument on his wrist. The Panadur lifted his great beryl eyes to the tall Terran and telepathed softly, "You don't expect me to agree to that!" "No," Bill smiled, "it was the expression of a hope. But tell me this, if as I expect, there's strife, what can you hope to add in my favor that would be as important as your being safe in the ship, were I to die?" Freml didn't answer right away.

Their marmoreal flesh had the cold whiteness of death, and their hair had grown until it spread in great festoons of yellow and black and silver grey. A fine,
