     Jim, a young farmer, was once put into prison.

     One day, he got a letter from his mother. "I'm so worried about our farm," she wrote. "It's time to plant

potatoes. I can't dig all the fields by myself. "

     Jim read the letter and became sad. "What can I do?" he thought. Then he had a good idea. He wrote

to his mother, "Don't dig the fields, there's a pot of money in the earth. Don't plant potatoes until I come

home."

     Some days later, Jim got another letter from his mother. It said, "Two days ago, about ten men came to

our farm and dug all our fields. I can't understand it. It looks as if they were looking for something. What
