Laura Davis grew up in London, far removed from the small country village she later moved to. Although not from an agricultural background, she wasn't impressed by what she had seen of conventional methods. Joining Laurence on the 32 acre smallholding of Bindon Farm provided a perfect opportunity to develop an organic system of farming.
"It was perfect really," she says. "We never considered using chemicals, so we were organic from the start. The land here had never been intensively farmed, it was all permanent pasture, and in the early days it was more an exercise in self-sufficiency than a working farm. Later, when we decided to operate commercially, we both did part-time courses at the local agricultural college. It was a general course, not particularly geared to an organic system. There is tremendous confusion about what 'organic' means. We describe organic produce as 'the products of a sustainable system of farming that is environmentally harmless.' In other words, 'organic' describes the system of farming rather than the produce itself. All land has a certain amount of naturally occurring chemicals in it. It's also possible that your produce can be marginally contaminated by, for instance, the farmer next door. So it is wrong to suggest that the product is completely free of chemical residue(残余物，残渣)."
The Soil Association is the body which approves land suitable for organic growing. Their inspectors issue a Soil Association symbol which can be used in the marketing of organic produce. To gain the symbol, land has to be free of chemical use for at least two years— sometimes longer, depending on how it has been used previously. The organic farmer also has to demonstrate competence in organic farming. The Soil Association was in its infancy when Laura and Laurence began and they were among the first to be awarded the symbol.
Why did Laura and Laurence start a farm？

Viruses Find New Ways to Worm into Computers
Just when you thought you knew a computer virus or worm when you saw one, several new infections that may fool you are gaining momentum on the Internet.
Most e-mail viruses require the victim to double-click open an infected attachment before they can wreak their havoc. But Badtrans-B and Aliz, two worms that were spreading quickly over the weekend and Monday, can launch themselves automatically when the recipient views or even just clicks on the subject line of an infected e-mail message using Microsoft's Outlook and Outlook Express programs. October's Nimda virus used a similar technique, which helped it spread further and faster than it otherwise might have. Computer users were safe from viruses as long as they didn't download programs from the Internet or open e-mail attachments. But these days, viruses are as capable of getting into computers as Santa Claus is at getting down chimneys.
Antivirus software maker McAfee, a division of Santa Clara, Calif.'s Network Associates, upgraded Badtrans-B to a high-risk virus for consumers. Vincent Gullotto, director of McAfee's virus lab, said the worm is infecting more home users than corporate networks.
To prevent these and other viruses from automatically launching themselves, Gullotto advised downloading a software patch from Microsoft at www. microsoft, com.
Badtrans-B and Aliz have shown up with many different subject lines, ranging from the Iow key "info" to "Fw: Funky pictures--check it."
Meanwhile, a worm called SirCam is still popping up regularly in e-mail boxes, months after it was first discovered. SirCam takes a Microsoft Word document from an infected computer and e-mails it out with a message reading "I send you this file in order to have your advice."
Gullotto attributed SirCam's staying power to social engineering. SirCam takes the title of the Word file as its subject line, which means the virus might arrive labeled anything from "business plan" to "diary." It is those sometimes-intriguing subject lines that entice people to open SirCam-laden attachments and spread the virus, Gullotto said.
To protect against all of these viruses, experts advise that computer users install antivirus software and regularly update it from the company's Website.
