     LONDON (Reuters) - British milkman Steve Leech, who saved several shops and flats by putting out

a fire with 320 pints of milk, was celebrating Thursday after winning a national bravery award.

     Leech, 35, named "Hero Milkman" by the National Dairymen's Association, said that he had noticed smoke

coming out of a shop in Cornwall, southern England, while delivering (递送) milk as usual a year ago.

     "I saw the flats up above and thought I'd better do something. So I kicked the door in and started pouring

milk everywhere," Lee told Reuters Thursday.

     "When firemen arrived, the fire was almost out," he said. Firemen said he had helped save the lives of

eight people living in the flats above the shops.
