It is true that a strong plea for equal suffrage might be addressed to the national sense of honor. Something, too, might be said of national gratitude. A nation might well hesitate before the temptation to betray its allies. There is something immeasurably mean, to say nothing of the cruelty, in placing the loyal negroes of the South under the political power of their Rebel masters. To make peace with our enemies is all well enough; but to prefer our enemies and sacrifice our friends,--to exalt our enemies and cast down our friends,--to clothe our enemies, who sought the destruction of the government, with all political power, and leave our friends powerless in their hands,--is an act which need not be characterized here. We asked the negroes to espouse our cause, to be our friends, to fight for us, and against their masters; and now, after they have done all that we asked them to do,--helped us to conquer their masters, and thereby directed toward themselves the furious hate of the vanquished,--it is proposed in some quarters to turn them over to the political control of the common enemy of the government and of the negro. But of this let nothing be said in this place. Waiving humanity, national honor, the claims of gratitude, the precious satisfaction arising from deeds of charity and justice to the weak and defenceless,--the appeal for impartial suffrage addresses itself with great pertinency to the darkest, coldest, and flintiest side of the human heart, and would wring righteousness from the unfeeling calculations of human selfishness. For in respect to this grand measure it is the good fortune of the negro that enlightened selfishness, not less than justice, fights on his side. National interest and national duty, if elsewhere separated, are firmly united here. The American people can, perhaps, afford to brave the censure of surrounding nations for the manifest injustice and meanness of excluding its faithful black soldiers from the ballot-box, but it cannot afford to allow the moral and mental energies of rapidly increasing millions to be consigned to hopeless degradation.
