Famous quotes containing the words cloud and/or base:

    On a cloud I saw a child,
    And he laughing said to me,

    “Pipe a song about a Lamb”;
    So I piped with merry chear.
    “Piper pipe that song again”—
    So I piped, he wept to hear.

    “Drop thy pipe thy happy pipe
    Sing thy songs of happy chear”;
    So I sung the same again
    While he wept with joy to hear.
    William Blake (1757–1827)

    The highest perfection of politeness is only a beautiful edifice, built, from the base to the dome, of ungraceful and gilded forms of charitable and unselfish lying.
    Mark Twain [Samuel Langhorne Clemens] (1835–1910)
