The gift

Oscola McCarty spent more than 75 years washing and ironing other
peoples clothes. Her lined hands were the evidence of hard work. So, it was a surprise, when Miss McCarty decided to give her entire life savings - $150,000 – to the University of Southern Mississippi. Miss McCarty's gift amazed even those who thought they knew her well.
The customers who have brought their laundry and ironing to her home for more than 75 years included three generations of some families. Initially she said she charged $1.50 to$2 a bundle but with inflation the price rose.
"When I started making $10 a bundle, I began to save money," recollected Miss McCarty, who was born on March 7 1908. "I put it in savings. I never would take any of it out. It just accumulated."
As her savings increased over years, McCarty washed and ironed and lived not a rich life. She never learned to drive and still walks everywhere she goes. When her mother and aunt died, they each left her some money, which she added to her savings. In 1947 her uncle died and left her a modest house in which she still lives.
Until her donation, she was afraid to fly and had only been out of the South once in 50 years. Since then she;s travelled all over the country and has been the subject of many interviews and articles. Shes even visited the White House and been honoured by the president.
Her donation of her life savings is for students who clearly demonstrate a financial need. "I want to help somebodys child go to college," said the quite spoken McCarty, who left school in sixth grade and has never married or had children. "I just want it to go to someone who will appreciate it and learn. I;m old. I;m not going to live always." Miss McCarty;s generosity inspired many to give money to the university, and contributions came in from all over the country. Her gift has now been more than doubled.
In a recent magazine interview McCarty was asked why she didn;t spend the money earned over a lifetime on herself. "I am spending it on myself"; she answered smilin
