If the six millions of colored people of this country, armed with the Constitution of the United States, with a million votes of their own to lean upon, and millions of white men at their back, whose hearts are responsive to the claims of humanity, have not sufficient spirit and wisdom to organize and combine to defend themselves from outrage, discrimination, and oppression, it will be idle for them to expect that the Republican party or any other political party will organize and combine for them or care what becomes of them. Men may combine to prevent cruelty to animals, for they are dumb and cannot speak for themselves; but we are men and must speak for ourselves, or we shall not be spoken for at all. We have conventions in America for Ireland, but we should have none if Ireland did not speak for herself. It is because she makes a noise and keeps her cause before the people that other people go to her help. It was the sword of Washington and of Lafayette that gave us Independence. In conclusion upon this color objection, we have to say that we meet here in open daylight. There is nothing sinister about us. The eyes of the nation are upon us. Ten thousand newspapers may tell if they choose of whatever is said and done here. They may commend our wisdom or condemn our folly, precisely as we shall be wise or foolish. We put ourselves before them as honest men, and ask their judgment upon our work. THE LABOR QUESTION. Not the least important among the subjects to which we invite your earnest attention is the condition of the labor class at the South. Their cause is one with the labor classes all over the world. The labor unions of the country should not throw away this colored element of strength. Everywhere there is dissatisfaction with the present relation of labor and capital, and to-day no subject wears an aspect more threatening to civilization than the respective claims of capital and labor, landlords and tenants. In what we have to say for our laboring class we expect to have and ought to have the sympathy and support of laboring men everywhere and of every color.
