                                                               A free trip

     "I didn't often have to trip!" he said, laughing. "Someone in a car is always ready to pick me up

if I stand by the road and wait. Do you often take people in your car?" said Ford.

     "Yes," said Patterson. "I stop for them when they look tired or poor. I feel sorry for them when

they're walking and I'm in my car. They haven't as much money as I have, and so I'm ready to help

them."But as he spoke, he turned his head and looked at Ford's coat. It was a good coat and

Patterson thought about it a lot as he kept us eyes on the road in front.
