In the profoundest ocean
There is a rainbow shell,
It is always there, shining most stilly
Under the greatest storm waves
That the old Greek called "ripples of laughter."
As you listen, the rainbow shell
Sings--in the profoundest ocean.
It is always there, singing most silently!

Katherine Mansfield
