Famous quotes containing the word field:

    After all the field of battle possesses many advantages over the drawing-room. There at least is no room for pretension or excessive ceremony, no shaking of hands or rubbing of noses, which make one doubt your sincerity, but hearty as well as hard hand-play. It at least exhibits one of the faces of humanity, the former only a mask.
    Henry David Thoreau (1817–1862)

    When white men were willing to put their own offspring in the kitchen and corn field and allowed them to be sold into bondage as slaves and degraded them as another man’s slave, the retribution of wrath was hanging over this country and the South paid penance in four years of bloody war.
    Rebecca Latimer Felton (1835–1930)

    Love to chawnk green apples an’ go swimmin’ in the
    lake.—
    Hate to take the castor-ile they give for belly-ache!
    ‘Most all the time, the whole year round, there ain’t no flies on
    me,
    But jest ‘fore Christmas I’m as good as I kin be!
    —Eugene Field (1850–1895)
