Minnie and Winnie

Minnie and Winnie
    Slept in a shell.
Sleep, little ladies!
    And they slept well.

Pink was the shell within,
    Silver without;
Sounds of the great sea
    Wander'd about.

Sleep, little ladies!
    Wake not soon!
Echo on echo
    Dies to the moon.

Two bright stars
    Peep'd into the shell.
"What are you dreaming of?
    Who can tell?"

Started a green linnet
    Out of the croft;
Wake, little ladies,
    The sun is aloft!
