But the Zytztzes took it and minded their own business and did their work. Mr. Zytztz asked Healey what to do with his pay, the captain suggested he open a savings account in the Interplanetary National Bank. The next time Healey dropped into the bank, the cashier astonished him with the information that every one of the seven hundred and seventy-seven Zytztzes had ordered their pay deposited in Mr. Zytztz's account. In the year 2130 the regular census was taken, and it showed seven hundred and seventy-seven Martians. No young ones. All adults. No deaths. No births. Healey could have asked Mr. Zytztz about that, but somehow he never quite had the nerve. That was odd, too, because Healey gave Mr. Zytztz duties that kept him on the bridge most of the time, and Healey asked him practically everything, and always got an answer. There were no evasions. But there were a few personal subjects on which the captain would think of talking to him, and he would turn to him to speak and something would stop him. Somehow or other Mr. Zytztz emanated quiet reserve that no sensitive man would try to penetrate under ordinary circumstances. Then Pickens retired. He wasn't an old man, and he had had a complete Osterhus rejuvenation and was good for sixty years more, but he was a defeated man. A dogged look was in his eyes when he told Healey: "I thought we'd be recognized by the Air Marines when we went to Mars, but it's no go. I'm giving up. I guess there's nobody more hard-headed than people." Healey and the rest of the pariahs had given up, too, by now, but no one but Admiral Pickens would admit it. They just didn't think much about it any more. CHAPTER VI Wall of Prejudice Finally Healey was promoted to rear admiral and put in charge of the expedition to Jupiter. They built a newer and bigger ship, and Senator Philipuster's niece, Clarissa, christened it the Twinkling Star with a bottle of champagne that made Commander Browne, Healey's adjutant now, lick his lips. They made a couple of shake-down cruises to Luna and then provisioned for the trip to Jupiter. Healey asked Mr. Zytztz to act as his escort—or valet, as they had said back in the nineteen hundreds—and they set off one night in a blast of green rocket flames that must have lighted up the entire island of Cuba.
