Famous quotes containing the word country:
“Though it is curious here,
unusually awkward to walk.
It is without grace.
There is no rhythm
in this country of dirt.”
—Anne Sexton (1928–1974)
“... there is a place in the United States for the Negro. They are real American citizens, and at home. They have fought and bled and died, like men, to make this country what it is. And if they have got to suffer and die, and be lynched, and tortured, and burned at the stake, I say they are at home.”
—Amanda Berry Smith (1837–1915)
