Hockley turned. For a moment he continued to stare at his assistant. Then his face broke into a narrow grin. "Of course you're right! There's only one way they'll ever learn it: go through the actual experience of what Ryke tutelage will mean." Most of the workrooms at Information Central were empty this time of evening. Hockley selected the first one he came to and called for every scrap of data pertaining to Rykeman III. There was a fair amount of information available on the physical characteristics of the world. Hockley scribbled swift, privately intelligible notes as he scanned. The Rykes lived under a gravity one third heavier than Earth's, with a day little more than half as long, and they received only forty percent as much heat from their frail sun as Earthmen were accustomed to. Cultural characteristics included a trading system that made the entire planet a single economic unit. And the planet had no history whatever of war. The Rykes themselves had contributed almost nothing to the central libraries of the galaxies concerning their own personal makeup and mental functions, however. What little was available came from observers not of their race. There were indications they were a highly unemotional race, not given to any artistic expression. Hockley found this surprising. The general rule was for highly intellectual attainments to be accompanied by equally high artistic expression. But all of this provided no data that he could relate to his present problem, no basis for argument beyond what he already had. He returned the films to their silver cans and sat staring at the neat pile of them on the desk. Then he smiled at his own obtuseness. Data on Rykeman III might be lacking, but the Ryke plan had been tried on plenty of other worlds. Data on _them_ should not be so scarce. He returned the cans and punched out a new request on the call panel. Twenty seconds later he was pleasantly surprised by a score of new tapes in the hopper. That was enough for a full night's work. He wished he'd brought Showalter along to help. Then his eye caught sight of the label on the topmost can in the pile: Janisson VIII. The name rang a familiar signal somewhere deep in his mind. Then he knew--that was the home world of Waldon Thar, one of his closest friends in the year when he'd gone to school at Galactic Center for advanced study. Thar had been one of the most brilliant researchers Hockley had ever known. In bull session debate he was instantly beyond the depth of everyone else. Janisson VIII. Thar could tell him about the Rykes! Hockley pushed the tape cans aside and went to the phone in the workroom. He dialed for the interstellar operator. "Government priority call to Janisson VIII," he said. "Waldon Thar. He attended Galactic Center Research Institute twenty-three years ago. He came from the city Plar, which was his home at that time. I have no other information, except that he is probably employed as a research scientist."
