Devall was not looking forward to leaving Markin. It was a pleasant world, if a little on the hot side, and there was no way of knowing what the next world would be like. A frigid ball of frozen methane, perhaps, where they would spend their year bundled into Valdez breathing-suits and trying to make contact with some species of intelligent ammonia-breathing molluscs. Better the devil we know, Devall felt. But he had to keep moving on. This was his eleventh world, and there would be more to come. Earth had barely enough qualified survey teams to cover ten thousand worlds half-adequately, and life abounded on ten million. He would retain whichever members of the current team satisfied him by their performance, replace those who didn't fit in, and go off to his next job eight months from now. He turned on the office fan and took down the logbook; unfastening the binder, he slipped the first blank sheet into the autotype. For once he avoided his standard blunder; he cleared his throat before switching on the autotype, thereby sparing the machine its customary difficulties in finding a verbal equivalent for his Br-ghhumph! The guidelight glowed a soft red. Devall said, "Fourth April, two-seven-zero-five. Colonel John F. Devall recording. One hundred nineteenth day of our stay on Markin, World 7 of System 1106-sub-a. "Temperature, 93 at 0900; wind gentle, southerly—" He went on at considerable length, as he did each morning. Finishing off the required details, he gathered up the sheaf of specialty-reports that had been left at his door the night before, and began to read abstracts into the log; the autotype clattered merrily, and a machine somewhere in the basement of the towering E-T Affairs Building in Rio de Janeiro was reproducing his words as the subradio hookup transmitted them. It was dull work. Devall often wondered whether he might have been ultimately happier doing simple anthropological field work, as he had once done, instead of taking on the onerous burden of routine that an administrative post entailed. But someone has to shoulder the burden, he thought. Earthman's burden. We're the most advanced race; we help the others. But no one twists our arms to come out to these worlds and share what we have. Call it an inner compulsion. He intended to work until noon; in the afternoon a Markin high priest was coming to the enclave to see him, and the interview would
