The little pony① cart② ran along the street. The driver，a young woman，spoke quietly to the pony.
"Now we must go a little faster，"she said."We would be sorry for us to be late at the station."
And so the pony quickened its steps.
Anna was used to traveling by cart. She fell and injured③ her knee some time ago. So now the little girl used pony to go around.
Sometimes horses injured their legs. That left them unable to work and unwanted.
People with bad legs sometimes had more luck. Anna went around with the help of her pony. At home，she helped her mother write stories for children. It was natural④ that Anna had story-telling talent⑤ to help her good friends：horses.
Anna was ill when she was fifty，when she began writing Black Beauty（A book about the lives of horses）. She was often too weak to hold the pencil herself，so she told much of the story to her mother，who wrote it down for her. Anna said she hoped the story would make people understand horses better. After seven years，the book was finished. Anna died three months later. And her book Black Beauty was a great success.
