When the sunlight strikes raindrops in the air,

they act like a prism and form a rainbow.  The

rainbow is a division of white light into many

beautiful colors.  These take the shape of a long

round arch, with its path high above and its two

ends apparently beyond the horizon.  There is ,

according to legend, a boiling pot of gold at one

end.  People look, but no one ever finds it.  When

a man looks for something beyond his reach, his

friends say that he is looking for the pot of gold

at the end of the rainbow.
