古老的苹果树
An apple tree stands alone near the top of a hill. It produces the Arkansas Beauty, a fruit long believed to have disap-peared from existence. Three years ago, plant experts E. J. Brandt and David Ben-scoter rediscovered it. They have found 13 long-lost apple varieties in an area once known as Oregon Territory in the north-western United States, which once had 17, 000 named varieties of domesticated apples, but only about 4,000 remain.
