Famous quotes containing the word sump:
“What did it matter where you lay once you were dead? In a dirty sump or in a marble tower on top of a high hill? You were dead, you were sleeping the big sleep, you were not bothered by things like that. Oil and water were the same as wind and air to you.”
—Raymond Chandler (1888–1959)
