Sedimentary Rock Formed

Famous quotes containing the words rock and/or formed:

    Safe upon the solid rock the ugly houses stand:
    Come and see my shining palaces built upon the sand.
    Edna St. Vincent Millay (1892–1950)

    The shifting islands! who would not be willing that his house should be undermined by such a foe! The inhabitant of an island can tell what currents formed the land which he cultivates; and his earth is still being created or destroyed. There before his door, perchance, still empties the stream which brought down the material of his farm ages before, and is still bringing it down or washing it away,—the graceful, gentle robber!
    Henry David Thoreau (1817–1862)
