     A good friend of mine lives with six hundred wild animals on a Greek island. Ever since he left school

(where I first knew him)he has traveled all over the world collecting animals for his very own zoo. He hoped

to collect two examples of every kind of animal 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 think 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 these animals eat. 

     My friend 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 round it), he found oil. He needs money for his travels, and for his zoo, and a

little oil would buy enough water for all his life; but he knows that if he tells anybody else about it, it will be the

end of his zoo, and his life's work.

     I know my friend,he will not tell anybody (except you and me) about what he found-because oil and water

do not mix.
