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.”
