Thank you for your letter. It was great to get some news from you. l have already been at home for a week because of the flu, I can't say that lam having a good time, but I'm trying to enjoy myself..I'm reading an interesting book about Mel Fisher. Have you ever heard of him? He was an explorer and a treasure huntert When he was a boy, his favourite book was Treasure lsland. Mel dreamed about avelling round the world, exciting adventures and treasure? When Mel grew up, he didn't forget about his dream. It took him 16 years of hard work. He looked for treasure from the Nuestra Senora de Atocha and the Santa Margarita: Spanish ships which Florida. Every day Mel said, Today is the day!" But only in 1985 Mel and his team found over 40 tons of silver and gold. There were Spanish coins, gold bars, wonderful decorations, royal plates and dishes and other historical things. Mel gave part of the found treasure to a museum which was then named the Mel Fisher's Treasure Nowadays this museum in Florida is very popular among children and teenagers who like stories about pirates and their treasure. Later Mel Fisher found some more ships, which were full of different historical orks of art and so he has become a famous person. Nobody else has found so many fantastic and valuable things. Would you like to find treasure? What would you do with the treasure you found? I would like to take part in the expedition of treasure hunters and find a bag full treasure. But I haven't decided what would do with the treasure got a dream? Do you believe that it can come true? The book about Mel Fisher says it's possible. Sorry, but I have to finish the letter. The doctor has come. Write back, please. Best wishes, Andrew
