 Which word doesn't describe Jeffers?
"Try not to be simple—for once!" growled Jeffers. It had been built for Ganymede, but not for Jeffers. "Okay I can't fire you legally—as long as you report for work," grumbled Jeffers, by now a shade more ruddy. Tolliver began to have his doubts the next day; which was "Tuesday" by the arbitrary calender constructed to match Ganymede's week-long journey around Jupiter. His contract guaranteed a pilot's rating, but someone had neglected to specify the type of craft to be piloted. On the bulletin board, Tolliver's name stood out beside the number of one of the airtight tractors used between the dome city and the spaceport, or for hauling cross-country to one of the mining domes. He soon found that there was nothing for him to do but hang around the garage in case a spaceship should land. Sometimes there's no reason but them for sending a ship back with a crew instead of in an economy orbit. Under a portable, double-chambered plastic dome blown up outside the ship's airlock, a crewman helped him load two trunks and a collection of bags into the tractor. They found they could send back loaded ships by 'automatic' flight—that is, a long, slow, economical orbit and automatic signalling equipment. And Daddy's little girl is trying too hard to sound like one of the gang. He enlarged upon other dangers to be encountered on the satellite, taking care to impress the newcomer with the daredeviltry of John Tolliver, driver of "missions" across the menacing wastes between dome and port. It did not, naturally, indicate he was drawing the salary of a space pilot. "Jeffers," he announced, "this is ... just call her Betty." Yes, indeed! Jeffers seemed to stagger standing still behind his desk. "Mr. Jeffers," said the girl, "I may look like just another spoiled little blonde, but the best part of this company will be mine someday. Jeffers now ignored him, intent upon the girl. "Daddy gave me the title of tenth vice-president mostly as a joke, when he told me to find out what was wrong with operations on Ganymede. "You can't prove anything," declared Jeffers hoarsely. Where are your books, Mr. Jeffers? He stared unbelievingly at Betty, and Tolliver thought he muttered something about "just landed." Tolliver, hardly thinking about it, expected the someone to be a secretary, but it turned out to be three members of Jeffers' headquarters staff.
