Southern Oscillation

Famous quotes containing the words southern and/or oscillation:

    I sometimes wonder that we can be so frivolous ... as to attend to the gross but somewhat foreign form of servitude called Negro Slavery, there are so many keen and subtle masters that enslave both north and south. It is hard to have a southern overseer; it is worse to have a northern one; but worst of all when you are the slave-driver of yourself.
    Henry David Thoreau (1817–1862)

    In almost all climes the tortoise and the frog are among the precursors and heralds of this season, and birds fly with song and glancing plumage, and plants spring and bloom, and winds blow, to correct this slight oscillation of the poles and preserve the equilibrium of nature.
    Henry David Thoreau (1817–1862)
