  • There I keep my treasures in a box-

    Shells and colored glass and queer-shaped rocks,

    In a secret hiding place I've made,

    Hollowed out with clamshells and a spade,

    Marked with yellow pebbles in a row-

    None of the other children know!

    - Margaret Widdemer, 'The Secret Cavern'.
