Famous quotes containing the word water:

    Here is no water but only rock
    Rock and no water and the sandy road
    The road winding above among the mountains
    Which are mountains of rock without water
    If there were water we should stop and drink
    Amongst the rock one cannot stop or think
    —T.S. (Thomas Stearns)
