Famous quotes containing the words lines and/or request:

    We joined long wagon trains moving south; we met hundreds of wagons going north; the roads east and west were crawling lines of families traveling under canvas, looking for work, for another foothold somewhere on the land.... The country was ruined, the whole world was ruined; nothing like this had ever happened before. There was no hope, but everyone felt the courage of despair.
    Rose Wilder Lane (1886–1968)

    Mr. Roosevelt, this is my principal request—it is almost the last request I shall ever make of anybody. Before you leave the presidential chair, recommend Congress to submit to the Legislatures a Constitutional Amendment which will enfranchise women, and thus take your place in history with Lincoln, the great emancipator. I beg of you not to close your term of office without doing this.
    Susan B. Anthony (1820–1906)
