Planet Explorer by Murray Leinster — Read

The nearer moon went by overhead. It was jagged and irregular in shape, probably a captured asteroid. Huyghens had seen it often enough, so he did not go out of his quarters to watch it hurtle across the sky with seemingly the speed of an atmosphere-flier, occulting the stars as it went. Instead, he sweated over paper-work, which should have been odd because he was technically a felon and all his labors on Loren Two felonious. It was odd, too, for a man to do paper-work in a room with steel shutters and a huge bald eagle -- untethered -- dozing on a three-inch perch set in the wall. But paper-work was not Huyghens' real task. His only assistant had tangled with a night-walker, and the furtive Kodius Company ships had taken him away to where Kodius Company ships came from. Huyghens had to do two men's work in loneliness. To his knowledge, he was the only man in this solar system.

Below him, there were snufflings. Sitka Pete got up heavily and padded to his water-pan. He lapped the refrigerated water and sneezed. Sourdough Charley waked and complained in a rumbling growl. There were diverse other rumblings and mutterings below. Huyghens called reassuringly, "Easy there! " and went on with his work. He finished a climate report, and fed figures to a computer. While it hummed over them he entered the inventory totals in the station log, showing what supplies remained. Then he began to write up the log proper.
