Far into the night burned the lights of countless laboratories. Noted physicists probed, measured, weighed, traced, X-rayed, dissolved, spun, peered at, photographed, magnetized, exploded, shattered and analyzed Super-Openers without achieving the glimmer of a satisfactory explanation. Competitors found the patent impossible to circumvent, for any departure from its exact specifications nullified the effect. Piltdon, genial these days with success and acclaim, roared at Feetch: "I'm putting you in for a raise. Yes sir! To reward you for assisting me with my invention I'm raising your pay two hundred dollars a year. That's almost four dollars a week, man." "Thank you, Mr. Piltdon." And still, thought Feetch wryly, he received no recognition. His name did not even appear on the patent. Well, well, that was the way it went. He must find his satisfaction in his work. And it had been interesting lately, the work he had been doing nights at home investigating what had been named the Piltdon Effect. It had been difficult, working alone and buying his own equipment. The oscillator and ultra microwave tracking unit had been particularly expensive. He was a fool, he supposed, to try independent research when so many huge scientific organizations were working on it. But he could no more keep away from it than he could stop eating. He still didn't know where the cans went, but somehow he felt that he was close to the answer. When he finally found the answer, it was too late. The Borenchuck incident was only hours away. As soon as he could get hold of Piltdon, Feetch said trembling, "Sir, I think I know where those cans are going. I recommend--" "Are you still worrying about that?" Piltdon roared jovially. "Leave that to the long-hairs. We're making money, that's all that counts, eh Feetch?" * * * * * That night, at six-ten p.m., the Borenchuck family of Selby, South Dakota, sat down to their evening meal. Just as they started in on the soup, a rain of empty tin cans clattered down, splashed into the soup, raised a welt on the forehead of Borenchuck senior, settled down to a gentle, steady klunk! klunk! klunk! and inexorably began to pile up on the dining-room floor. They seemed to materialize from a plane just below the ceiling. The police called the fire department and the fire department stared helplessly and recommended the sanitation department. The incident made headlines in the local papers. The next day other local papers in widely scattered locations reported similar incidents.
