Famous quotes containing the words reference and/or clock:

    “I think, for the rest of my life, I shall refrain from looking up things. It is the most ravenous time-snatcher I know. You pull one book from the shelf, which carries a hint or a reference that sends you posthaste to another book, and that to successive others. It is incredible, the number of books you hopefully open and disappointedly close, only to take down another with the same result.”
    —Carolyn Wells (1862–1942)

    “The clock runs down
    timeless and still.
    The days and nights turn hours to years
    and water in a gutter marks the circle of another world
    hating, resentful, and afraid
    stagnant, and green, and full of slimy things.”
    —Margaret Abigail Walker (b. 1915)
