``Diamonds! What do you want with diamonds?'' ``Why, I wish to be immensely rich.'' ``Well, then, go along and find them. That is all you have to do; go and find them, and then you have them.'' ``But I don't know where to go.'' ``Well, if you will find a river that runs through white sands, between high mountains, in those white sands you will always find diamonds.'' ``I don't believe there is any such river.'' ``Oh yes, there are plenty of them. All you have to do is to go and find them, and then you have them.''
