Unterzuyder ripped the wet cloth from his head and threw it somewhere. He laughed. He weaved about the room, holding his head and hooting, while Foshag and Beecher looked on with open mouths. Then Foshag forced him into a chair. "Out of his head! Mr. Unterzuyder, please be quiet. That's better. There, there! Now we're going to leave you here for your own protection, Mr. Unterzuyder. The settlers are somewhat provoked. Do you agree?" Unterzuyder grinned widely up at him. "I'm sick," he groaned. "Tell Fayette I need her." _There's still X to find._ An idea had come to him. * * * * * He was in bed, the white cloth on his forehead, when Fayette walked in. She looked at him without sympathy. Tentatively, she sat on the edge of the bed, curling one knee under another. "I'm sorry if you think I played Delilah, Ralph--" she began. He patted her knee delicately. "There, there," he soothed.

"We'll get married and live on Titan," he said. She leaned over and kissed him until he thought he'd be forced down through the bed. He added, "But first I've got to get back in the good graces of the settlers." When she smiled incredulously, he said with confidence, "It should be easy." And besides, it was necessary. * * * * * As soon as Fayette left, he leaped out of bed and grabbed an encyclopaedia out of the bookcase. He looked up _Unterzuyder_, tracing down until he found the expected paragraph: _The fabulous cartels of the Unterzuyders were built up through their amazing instinct on the stock market. When the market was bullish, they seemed to know when the crest was reached. Selling short in heavy amount at this point, they reaped millions in profit as the market fell, then caught the market again on the upswing. Invariably, the bulls were caught short by the Unterzuyder bears. The Unterzuyders seemed to draw some special inspiration from one famous interpretation of their name, i. e._, undersiders, _those who work from the underside_....
