Problem:Laura Collins:  And there are the tallest palm trees with trunks curving up into the sky . The kind of trees that make a wonderful nesting place for the Phoenix .
David Collins: The Phoenix ? What 's that ?
Laura Collins: A legendary bird . A bird that 's said to live forever .
David Collins: I 've never ... I 've never even heard of it .
Laura Collins: Well , not many people have . In fact , it 's said there 's only _ one _ on Earth at a time .
David Collins: Hmm , what does it look like ?
Laura Collins: Oh , it 's very beautiful . It has a scarlet head and body , and ... And it has sea blue eyes . And its wings are iridescent .
David Collins: I wish I could see one .
Laura Collins: Well , perhaps you can . In your imagination . Try . Try to picture the beautiful bird flying high in the clouds and the flap of its wings as it flies from century to century .
David Collins: It must be pretty old .
Laura Collins: Well , that 's one of the fascinating things about it . It does n't grow old for a hundred years and even then it does n't lose its beauty . Then one day , it feels its wings growing heavier and it knows it hasn't much time . It hears death calling so it knows what it must do . It starts on its last long flight in search of the very tallest palm tree . Then it gathers up all the sweet smelling spices and it builds a very special nest on top of the tree . And then at dawn the Phoenix awakes and begins to sing . And then the sun rises . Oh , the rays become very strong and they beat down on the dry nest . And slowly it starts to smolder . And the Phoenix fans the spark with its wings until the entire nest is ablaze . And the beautiful feathers , they all catch on fire . The whole bird is consumed in flame and burned to ashes . And from these ashes the Phoenix is reborn . Reborn to live on and spend the next hundred years in Paradise .
