Fred, a close friend of mine, lives with six hundred wild animals on a small island.Ever since he left school, where I first knew him, he has traveled all over Africa collecting animals for his zoo.He hoped to collect at least two animals of each kind on his island, like Noah before the Great Flood.But the flood that my friend was afraid of was a flood not of water, but of people.I expect you have heard of my friend; he writes books about his travels, and about the wild and wonderful animals that he collects.The money from the books helps to pay for all the food that those animals eat.
Fred told me that when he was out looking for water last week(there is not enough water on the island, though there is plenty all around it), he found oil.He needs money for his travel, and for his zoo, and a little oil will buy enough water for a lifetime; but he knows that if he tells anybody else about it, it will be the end of his zoo and his life's work.
