     Wherever she goes, Molly leaves her mark. Without saying a word, she speaks to people with her

kind eyes.  Even when she walks away, she leaves an impression. Molly's mark is a smile, stamped into

the ground by the horseshoe at the bottom of her false leg.

     A few years ago, Molly was badly attacked by a dog. The dog bit all four or Molly's legs and left

large cuts in her face. Molly's owner, Kate Harris, took  her to an animal hospital. Doctors there were

able to save Molly's life, but soon one of her legs became very infected(感染).

     At first, doctors thought Molly would have to be put to sleep. But Molly changed their minds. This

pony, doctors noticed, shifted her weight, and rested her good leg from time to time. Doctors knew that

Molly had amazing intelligence, and that she wanted to live.

     Several doctors operated on Molly, and removed her infected leg. A false leg was made for her. The

leg was a hollow case with a pole at the bottom for balance. Doctors gave Molly a special horseshoe at

the bottom of the leg. This horseshoe she had a stamp of a smile face in it!

     After the operation, Molly walked around on all four legs, as if nothing had ever happened to her!

Now, with every step she takes, she stamps a smile in the dirt. But she leaves her mark in other ways,

too.

Kaye Harris took Molly to the false leg center. There were children there who, like Molly, had artificial

arms or legs. They were amazed to see a pony with a false leg. Molly made them smile and gave them

hope. Soon, Molly began to visit schools, nursing homes,army bases and hospitals. A book was even

written about Molly!
