Visibly amused, Matt Henderson departed, repeating his formula about brands of liquor. This time, Elvin thought, the reporter actually believed it. Elvin walked back to the ranch. He was very angry; but, more than that, he was coldly afraid--and he had no idea what he was afraid of. The Schermerhorn twins stopped him as he crossed the driveway. "You sure made us bite on that one, Mr. Elvin," Donald said good naturedly. "Yeah," David added. "All the kids came over early this morning to see your rocket." "I guest we deserve it, though," Donald went on philosophically, "for pulling that deal on you in class last week." * * * * * Gary Elvin went up to his room in a daze and sat staring at the bottle of colored spheres. It seemed entirely clear what had happened last night; yet, conceivably, the rocket could have been an hallucination. If so, it was because of the grinding frustrations of his job. But Elvin had a good mind; he did not have to let a bunch of discourteous rattle-brained kids get him down. David and Donald had given him the clue: the rocket was simply a practical joke he had played on his class of tenth graders. The second step in driving out the "dream" was an appeal to authority. He must understand the limits of scientific possibility in the use of rockets. That meant a trip to the library. Although it was four miles to San Benedicto, Elvin decided to walk; the exercise would help clear his head. He entered the library at eleven-thirty, half an hour before the building was closed for the weekend. It was a good library. The assessment rate in prosperous San Benedicto was high, and books had been purchased wisely. In the card catalogue Elvin found listed a number of up-to-date references that he could use; but there was nothing on the shelves. Five minutes before closing time, he asked the librarian for help. "I don't suppose there's anything in," she answered. "We've had a perfect run on books all morning." "You mean everything in the library is out?" "Everything worthwhile." She beamed. "And most of the borrowers were your tenth graders, too, Mr. Elvin. You've certainly done a wonderful job of inspiring that class to do serious reading. Why, do you know Mabel Travis has been in here three times today? She took out seven books as soon as the library opened, and she had them back by nine-thirty. Said she'd read them all, too." "Seven books in less than two hours?" Elvin laughed. "I suppose she thought she had. Poor little Mabel! She hasn't much to work with, you know. But it was her new attitude I liked--so intense, so serious. And she was doing such heavy reading, too."
