Mr King lived with six hundred wild animals on the Greek Island of Kyklos．Ever since he left school, he had travelled all over the world collecting animals for his own zoo．He hoped to collect two examples of every kind of animal on his island．But he was afraid that people would find him someday．

　　He wrote books about his travels, and about his animals that he collected．The money from the books helped to pay for all the food that these animals eat．

　　One day, when Mr King was out looking for drinking water, he found oil(石油)．He needed money for his travels and for his zoo, and a little oil would buy enough water for what he needed all his life, but he know that if he told anybody else about it, it would be the end of his zoo and his life's work．So he decided not to tell anyone about what he had found．
