On a Friday night，a poor young violinist was playing his violin at the entrance（入口）of the subway station．He played such great music that people slowed down to listen and put some money into his hat．

The next day，the violinist came to the entrance again．He put down his hat as usual．Beside the hat was a piece of paper with some words on it．It said，"A George Black has put an important thing into my hat by mistake．Welcome to clain（认领）it．"Soon the people were all interested in the words and wondered what itcould be．After a while，a man rushed into the crowd，took the violinist's shoulders and said，"I knew you would certainly come．"The violinist asked，"Did you lose anything？""Lottery（彩票）．"The violinist took out a lottery ticket with Black's name on it．Black took it and danced happily．

Black was an office worker．He bought the lottery and won a prize of﹩500，000．But when he gave﹩50 to the violinist for his wonderful music，the lottery ticket was thrown in，too．The violinist was a college student．That morning，he was going to fly to Vienna for high education．However，when he found the ticket，he put off the flight and went back to the entrance．
