The thing paused a few lengths away. "Advance and be recognized," it said. He took a faltering hop forward. "Halt or I'll shoot," it said, and he stopped. "Advance." He did. "Halt." He did. Finally he was very close to it, and he waited for a spell to hit him. "Name, rank, and serial number," it demanded. Then, as he was silent "Speak or I'll shoot." "I—I'm Alyarsmit! I don't think I'm rank, and I don't know what a serial number is." "Friend or foe?" "F-friend. I haven't stolen anything. Just some girls." The thing made a buzzing sound. "You speak, and you have the requisite number of limbs, and one head. Are you human?" "Y-yes, I'm human." "Name?" "Alyarsmit." "Smith? Smith?" It buzzed some more. "There was a Colonel John Smith on the roster. Are you his descendant?" "Yes," Alyar hazarded. "Mr. Smith, sir, Robojeep twenty-seven four nine reporting. All other jeeps inactivated, sir. No ship's personnel or other passengers accounted for in the last three hundred and seventy-four planetary cycles. Damage to ship unrepairable without human direction. Sporadic raids by savages, possibly degenerate humans, repelled successfully. Will you assume manual control, sir?" Alyar stuck with "Yes."
