Famous quotes containing the words keith and/or clusters:

    But we are the people of England; and we have not spoken yet.
    Smile at us, pay us, pass us. But do not quite forget.
    —Gilbert Keith Chesterton (1874–1936)

    What wondrous life in this I lead!
    Ripe apples drop about my head;
    The luscious clusters of the vine
    Upon my mouth do crush their wine;
    The nectarine and curious peach
    Into my hands themselves do reach;
    Stumbling on melons, as I pass,
    Ensnared with flowers, I fall on grass.
    Andrew Marvell (1621–1678)
