Famous quotes containing the words points and/or saddle:

    A few ideas seem to be agreed upon. Help none but those who help themselves. Educate only at schools which provide in some form for industrial education. These two points should be insisted upon. Let the normal instruction be that men must earn their own living, and that by the labor of their hands as far as may be. This is the gospel of salvation for the colored man.

    Rutherford Birchard Hayes (1822–1893)

    As the saddle makes the horse, so the tailor makes the man.
    Chinese proverb.
