　　There’re many rich people in this part of the country because gold was once found here．I was only a small child at the time but I can remember everything well．

　　Men came from everywhere to look for gold．They bought all the ground near the banks of the river．They made big holes in it, trying to find more gold．Some men found a lot, others found none at all．

　　Peter Fullerton was one of those who came to find gold．He bought nearly the last piece of ground．It was a long way from the river so no one else wanted to buy it．But Peter paid all his money for it．He worked hard month after month until the ground was full of holes．But Peter found nothing．

　　Then one night, just before he was going to leave, it began to rain．It rained for three days and three nights．When at last the rain stopped, Peter came out of his small wooden house and looked at his piece of ground．It didn't look the same now．The holes were not there any more．But everywhere therer were small plants．

　　“ There may be no gold here, ” Peter said, “ but this ground is rich．I can grow things here, I can grow flowers and I can sell them．The women in this town have money now．They have beautiful houses and they will want to put flowers in their houses．If I can grow good flowers here, I will make money, too．” So he did．And soon beautiful flowers were growing in his piece of ground．Later he was able to buy more fields until he owned all the ground near the river．

　　“ I was the only man who found true gold here, ” he often said, “ The others took their gold out of the ground and went away．But my gold is still here．”

　　Mr Green lives in a village．He has a few farms and is the richest there．And he has pigs, chicks, cows and sheep．He works in the fields with some workers, and his wife has to do all the housework at home．So she's very busy and asks her husband to employ a girl to help her, but he doesn't agree．

　　“There're so many chicks, dear,”said the woman one day,“I can't look after them at all．”

　　“That's easy,”said Mr Green,“There's Mr Black's farm outside our enclosure walls(围墙)．We'd better make a few holes in the walls and the chicks will go to his farm through them and eat his vegetables．”

　　“That's a good idea．”the woman said happily．

　　And soon Mr Black knew about it．He told Mr Green and his wife about it． They promised they would stop their chicks doing it but they didn't keep their promises at all．The man thought for a while and found a way．He put nearly twenty eggs near the holes one afternoon．And that evening, when Mrs Green was counting her chicks, he cried out in his farm,“Oh, I'm lucky today!I've found twenty eggs in my farm．”

　　Of course, the woman saw it herself．And the next morning Mr Black found all the holes had been stopped up(堵死)．
