Then she went on to ask, "Did you remember to buy gas yesterday?" "No," he said without thinking; then, realizing his mistake, quickly added, "I'll buy some in Wheaton. There's enough to get us there." "You didn't think so yesterday," she objected. "You said the tank was nearly empty." "I was wrong. Look, the gauge shows it's half full." "But then how ... Ernie, didn't you once tell me the gauge doesn't work?" "Did I?" "Yes. Look, there's a station. Why don't you buy gas now?" "No, I'll wait for Wheaton--I know a place there I can get it cheaper," he insisted, rather lamely, he feared. His sister looked at him steadily. He settled his head between his shoulders and concentrated on driving. His feeling of excitement was spoiled, but a few minutes of silence brought it back. He thought of the blur of green flashes inside the purring motor. If the passing drivers only knew! Uncle Fabius, retired perhaps a few years too early and opinionated, was a trial, but he did know something about the automobile industry. Ernie chose a moment when his sister was out of the room to ask if he'd ever heard of a white powder that would turn water into gasoline or some usable fuel. "Who's been getting at you?" Uncle Fabius demanded sharply, to Ernie's surprise and embarrassment. "That's one of the oldest swindles. They always tell this story about how this man had a white powder or something and demonstrated it once with a pail of water and then disappeared. You're supposed to believe that Detroit or the big oil companies got rid of him. It's just another of those malicious legends, concocted--by Russia, I imagine--to weaken your faith in American Industry, like the everlasting battery or the razor blade that never gets dull. You're looking pale, Ernie--don't tell me you've already put money in this white powder? I suppose someone's approached you with a proposition, though?" * * * * * With considerable difficulty, Ernie convinced his uncle that he had "just heard the story from a friend." "In that case," Uncle Fabius opined, "you can be sure some fuel-powder swindler has been getting at _him_. When you see him--and be sure to make that soon--tell him from me that--" and Uncle Fabius began an impassioned ninety-minute defense of big business, small business, prosperity, America, money, know-how, and a number of other institutions that defended pretty easily, so that the situation was wholly normal when Ernie's sister returned. As soon as the car pulled away from the curb on their way back to Chicago, she reminded him about the gas. "Oh, I've already done that," he assured her. "Made a special trip so I wouldn't forget. It was while you were out of the room. Didn't you hear me?" "No," she said, "I didn't," and she looked at him steadily, as she had that morning. He similarly retreated to driving.
