Up From Slavery

From the text:

Casting down your bucket among my people, helping and encouraging them as you are doing on these grounds, and to education of head, hand, and heart, you will find that they will buy your surplus land, make blossom the waste places in your fields, and run your factories. While doing this, you can be sure in the future, as in the past, that you and your families will be surrounded by the most patient, faithful, law-abiding, and unresentful people that the world has seen.
