Billy Graham, U.S. evangelist, has been discharged from a North Carolina hospital after being treated for pneumonia. The 92-year-old minister was admitted to Mission Hospital in Asheville last Wednesday. Graham was allowed to leave the hospital and was back at his home in Montreat yesterday afternoon. His physicians are expecting Graham to make a gradual but full recovery over the next few weeks. As he recuperates, Graham is expected to complete a book about ageing.
