In the history of mankind the crime against the African race will stand forth in terrible eminence,--always observed, and never forgotten. Just in proportion as civilization prevails will this enormous wrong be apparent in its true character; and men will read with astonishment how human beings, guilty only of being black, were sold into slavery, and then (such was the continuing injustice towards this unhappy people) how, when slavery ceased, they were still treated with indignity by persons whose lordly pretensions were founded on the skin only. As these things are seen in increasing light, they will be condemned in no uncertain words; nor will the denial of equal rights, on account of color, escape the judgment awarded to slavery itself. Human conduct on this question is a measure of character. Where the African race is enslaved or degraded, where it is exposed to any indignity or shut out from that equality which is a primal right to humanity, there civilization is still feeble. To the certain triumph of civilization I look with constant hope. It is sure to come; and one sign of its arrival will be that prevailing sentiment which recognizes the perpetual obligations of equal justice to all, and the duty to repair past wrongs by compensations in the future. In the great debt of the whites to the blacks there is a bank from which, for generations to come, the latter can draw. Accept, Mr. President, the expression of my ardent hope for the peace, prosperity, and happiness of the Republic of Hayti, and allow me to subscribe myself with true regard, Your faithful friend, CHARLES SUMNER. TO THE PRESIDENT OF THE REPUBLIC OF HAYTI. INTERNATIONAL ARBITRATION. LETTER TO HENRY RICHARD, M. P., ON THE VOTE IN THE HOUSE OF COMMONS AGREEING TO HIS MOTION FOR AN ADDRESS TO THE QUEEN, PRAYING COMMUNICATION WITH FOREIGN POWERS WITH A VIEW TO A GENERAL AND PERMANENT SYSTEM OF INTERNATIONAL ARBITRATION, JULY 10, 1873. UNITED STATES SENATE CHAMBER, WASHINGTON, July 10, 1873. MY DEAR SIR,--Few events have given me more pleasure than the vote on your motion. I thank you for making the motion; and I thank you also for not yielding to Mr. Gladstone’s request to withdraw it. You were in the very position of Buxton on his motion against Slavery. He, too, insisted upon a division; and that vote led to Emancipation. May you have equal success! I anticipate much from this vote. It will draw attention on the Continent, which the facts and figures of your speech will confirm.
