Famous quotes containing the word mar:
“In those days, the blag slag, the waste of the coal pits, had only begun to cover the side of our hill. Not enough to mar the countryside nor blacken the beauty of our village. For the colliery had only begun to poke its skinny black fingers between the green.”
—Philip Dunne (1908–1992)
