Washington began with a call to the blacks, who composed one third of the Southern population, to join the world of work. He declared that the South was where blacks were given their chance, as opposed to the North, especially in the worlds of commerce and industry. He told the white audience that rather than relying on the immigrant population arriving at the rate of a million people a year, they should hire some of the nation's eight million blacks. He praised blacks' loyalty, fidelity and love in service to the white population, but warned that they could be a great burden on society if oppression continued, stating that the progress of the South was inherently tied to the treatment of blacks and protection of their liberties.
