    Mr. Peter Johnson, aged twenty-three, battled for half an hour to escape from his trapped car yesterday

when it la nded upside down in three feet of water. Mr. Johnson took the only escape route-through the boot

(行李箱).

    Mr. Johnson's car had finished up in a ditch (沟渠) at Romney Marsin, Kent after skidding on ice and hitting

a bank. "Fortunately, the water began to come in only slowly," Mr.Johnson said. "I couldn't force the doors

because they were jammed against the walls of the ditch and dared not open the windows because I knew

water would come flooding in." 

    Mr.Johnson, a sweet salesman of Sitting Home, Kent, first tried to attract the attention of other motorists

by sounding the horn and hammering on the roof and boot.Then he began his struggle to escape.

     Later he said, "It was really a half penny that saved my life. It was the only coin I had in my pocket and

I used it to unscrew the back seat to get into the boot.I hammered desperately with a hammer trying to make

someone hear, but no help came."

     It took ten minutes to unscrew the seat, and a further five minutes to clear the sweet samples from the

boot.Then Mr. Johnson found a wrench and began to work on the boot lock.Fifteen minutes passed by. "It

was the only chance I had. Finally it gave, but as soon as I moved the boot lid, the water and mud poured in.

I forced the lid down into the mud and scrambled clear as the car filled up."

     His hands and arms cut and bruised (擦伤), Mr.Johnson got to Beckett Farm nearby, where he was looked

after by the farmer's wife, Mrs. Lucy Bates. Huddled in a blanket, he said, "That thirty minutes seemed like

hours." Only the tips of the car wheels were visible, police said last night.The vehicle had sunk into two feet

of mud at the bottom of the ditch.
