It is really important that this be done at once. Very respectfully, your obedient servant, Z. CHANDLER. _To President U. S. Grant._ AUTOGRAPHIC ENDORSEMENT BY PRESIDENT GRANT. Referred to the Secretary of the Interior. I think Mr. Brockway might with great propriety be assigned to the Indian agency in his own State, to which he has once been appointed and confirmed. He is a minister, and therefore the new rule adopted will not be violated by his appointment. I want, besides, to accommodate Senator Howard, whom I regard as an able supporter of the Republican party and of the Administration. Sept. 22, 1870. U. S. GRANT. Mr. Chandler was a member of one or two of the special Congressional committees appointed to investigate those atrocious political murders which made infamous the return of the disloyal classes to power in the South. This general subject received no small share of his attention; the facts which investigation disclosed deepened his conviction of the essential barbarity of much that passes for civilization in that section, and added to the inflexibility of his opposition to a political system, which was responsible for the atrocious crimes of the Ku-Klux-Klan, "the Mississippi plan," the White League, and the "rifle clubs," and for the horrible massacres of Colfax and Coushatta, of Hamburg and Ellenton. Two of his speeches in the Senate in 1871 and 1872 attracted general attention and were widely republished. One of them was delivered on January 18, 1871, in reply to Mr. Casserly of California, who had challenged a comparison between the records of the Republican and Democratic parties. In the course of twenty minutes Mr. Chandler rapidly sketched the services of the Republican party in defeating the Democratic plot to surrender the territories to slavery, in crushing a Democratic rebellion, in emancipating four million slaves, in building a trans-continental railway to the Pacific coast, in inviting the settlement of the Great West by a homestead law, in establishing the national banking system, in maintaining the public credit against Democratic attack, and in reconstructing the South on the basis of freedom and loyalty. He closed as follows: These measures were carried, not with the Democratic party, but in spite of the Democratic party. Sir, we are not to be arraigned here and put on the defensive, certainly not by that old Democratic party.
