Jim is a young farmer. He was once put into prison(监狱).
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(挖)all the fields(田地)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 is much 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 the fields. I can't
understand it. It seemed that they were looking for something. What should I do?"
Jim smiled when he read his mother's letter. He wrote a letter to his
mother at once. It was very short. Guess what it would say.
