Sometime in the middle of the 15th century, a well-to-do merchant from London buried more than 6, 700 gold and silver coins on a sloping hillside in Surrey. He was fleeing the War of the Roses and planned to return during better times. But he never did. The coins lay undisturbed until one September evening in 1990,when local resident Roger Mintey chanced upon them with a metal detector, a device used to determine the presence of metals. Mintey's find—much of which now sits in the British Museum—earned him roughly $ 350,000, enough to quit his job with a small manufacturer and spend more time pursuing lost treasure. But digging up the past is controversial in Britain. In many European countries, metal detectorists, or people using metal detectors, face tough regulations. In the U. K., however, officials introduced a scheme in 1997 encouraging hobbyists to report their discoveries(except for those falling under the definition of treasure, like Mintey's find, which they are required to report)—but allowing them to keep what they find, or receive a reward. Last year, a hidden store was uncovered in a field outside Birmingham. It consists of more than 1,500 gold and silver objects from the seventh century and was valued at more than $ 4.5 million. While local museums hurry to raise enough money to keep the find off the open market, it sits in limbo, owned by the Crown but facing claims by the landowner and the metal detectorist who found it. The find marks the latest battleground in the increasingly heated conflict between the country's 10, 000-20,000 metal detectorists and the museum workers determined to protect its precious old objects. Supporters say the scheme stems the loss of valuable information about precious old objects, while opponents argue that metal detectorists don't report everything. The debate centers on the larger question of who owns the past. "There's been a slow move over the centuries that precious old things belong to us all," says Professor Christopher Chippindale of Cambridge University. But in Britain at least, the temptation of buried treasure could change all that.

Textbook prices are traditionally high. " Combined with the rising cost of tuition, the price of books for our students is just killing these kids," said Peter Jason, Ph.D. , a local community college professor. Adding to that problem, many college instructors change textbooks year after year: they either upgrade to a new edition or switch to an entirely different textbook. This further hurts students because if an instructor no longer uses a particular textbook, that book has no resale value. Students are one of the poorest groups of people in America. Almost half of them have at least one part-time job. In fact, some even have three jobs and still manage to have high grades and go to school full-time. So Dr. Jason decided to make life a little easier and a lot cheaper for his students by writing his own book on public speaking. He thinks that many books have an increased price because of bells and whistles : CD-ROMs, lots of color photographs, and lots of graphics. He talked to his students, and many of them, like him, prefer to keep things simple. They want to have a book which is brief and concise, not long-winded. A few years ago Dr. Jason finished his own textbook. " Compared to most other public speaking primers(启蒙书), mine is half the number of pages, and one-third the price. That is, $ 30 instead of $ 90. Plus, it is published in a three-ring binder format. So, when I wrote a second edition last year, students only had to buy the 35 new pages and delete 35 of the original pages. For only $ 7.00, they had upgraded to the new edition. I' ve had great feedback from my students about this loose-leaf concept. Maybe the word will get out, and more writers and publishers will try it," said Dr. Jason.
