The winter of 1948 was very difficult for our family of eight living in Knoxville, Tennessee. Unluckily, Dad became ill and was soon out of a job. I was only 8 years old and my younger brother Buddy Earl was 7. After school it was our responsibility to pick coal that fell from the coal cars along the railways.
One day, A train stopped for a short time because of a wreck(损坏). My brother and I were digging around in the snow when the train’s fireman (司炉工) shouted to us: “Why are you boys digging in the snow? Are you looking for gold?” He laughed.
“No, sir,” I replied, “We are looking for coal.”
“Why doesn’t your daddy buy coal so you can stay away from the trains? It’s really dangerous for two little kids here.”
“Our daddy is very sick and we have no money to buy food, much less coal,” I answered.
The fireman turned and went inside, and my brother and I began searching for coal again.
“Hey!” a voice sounded behind us. “You two bring that coal basket over here. I’ve got something for you.”
The fireman took the basket from us and filled it with clean coal. We were so excited that we knew we’d be able to go home early that day. He smiled the kindest and warmest smile I had ever seen.
All that winter, three days a week, we received a basket of coal, a treat and sometimes money. I never knew the person’s full name, but to our family, he was an angel of mercy(仁慈).
