Once upon a time there was a wood-mouse, and her name was Mrs. Tittlemouse. She lived in a bank under a hedge. Such a funny house! There were yards and yards of sandy passages, leading to storerooms and nut-cellars and seed-cellars, all amongst the roots of the hedge. Beatrix Potter was an English author, illustrator, and natural scientist. Her imaginative children's books feature many natural animals that can be found in the British countryside. She is credited with preserving much of the land that now comprises the Lake District National Park. Beatrix Potter's Peter Rabbit story is among the most popular children's stories worldwide.
