Famous quotes containing the word field:

    Wynken and Blynken are two little eyes,
    And Nod is a little head,
    And the wooden shoe that sailed the skies
    Is a wee one’s trundle-bed.
    —Eugene Field (1850–1895)

    The little toy dog is covered with dust,
    But sturdy and stanch he stands;
    And the little toy soldier is red with rust,
    And the musket moulds in his hands.
    Time was when the little toy dog was new,
    And the soldier was passing fair;
    And that was the time when our Little Boy Blue
    Kissed them and put them there.
    —Eugene Field (1850–1895)
