Even better, Paley's Remote Scanning Services Company could detect crop problems before they be- came visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color, code map showing where plants were running "fevers". Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.
The had news is that Paley's company closed down in 1984, after only three years. Farmers resisted the new technology and long-term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. "This technique can be used on 75 percent of agricultural land in the United States", says George Oerther of Texas A&M. Ray Jackson, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago.

My mother would never let us kill a spider, not even a hairy old grandfather. "If you want to live and rich," she used to say, "let a spider run alive." And so the spiders, our enemies, were beaten and kicked but never killed. But she had no such dealing with the mice.
One of our problems was that my mother hated cats; and we never owned a single cat. We kept dogs, often two or three at the same time, but very few dogs can move fast enough to catch a lively young mouse. Every night we set a dozen mousetraps(捕鼠器), each with a small piece of cheese. Sometimes the cheese disappeared, but the mice usually seemed too wise to go near the traps. We seldom caught anything.
My mother herself had far better luck. Her arms and hands moved as fast as any cat's paws. Often, when she was scrubbing or polishing a floor on her hands and knees, some foolish little grey fellow would try to run past her. He never got very far. Quick as lightning her hard hands would smack(用掌击) together--and there on the floor would be one dead mouse. "Oh, you were a proud one," she would say to it then.
One day my father decided to clean out the water tank, which stood on four iron legs in a corner upstairs. He was soon sorry that he had started the job. In the mud at the bottom of the tank, there were sixteen of the little grey fellows, all as solid and hard as stones. We had been drinking the water from that tank for twelve years.
