Lesson22 A glass envelope
My daughter, Jane, never dreamed of receiving a letter from a girl of her own age in Holland. Last year, we were traveling across the Channel and Jane put a piece of paper with her name and address on it into a bottle. She threw the bottle into the sea. She never thought of it again, but ten months later, she received a letter from a girl in Holland. Both girls write to each other regularly now. However, they have decided to use the post-office. Letters will cost a litt1e more, but they will certainly travel faster.
