The abuses in Missouri, to which Mr. Sumner called attention, December 4, 1861, appeared even in the neighborhood of Washington, almost under the eye of Congress, so that he felt it his duty to expose them once more. December 18, he spoke briefly on the following resolution, introduced by himself the preceding day. “_Resolved_, That the Committee on Military Affairs and the Militia be directed to consider the expediency of providing by additional legislation that our national armies shall not be employed in the surrender of fugitive slaves.” MR. PRESIDENT,--Some days ago it was my duty to expose abuses in Missouri in regard to fugitive slaves. Since then I have received communications from that State, showing great interest in the question, some of them in the nature of protest against the system adopted there. One purports to be from a slave-master, educated in a Slave State, and he speaks with bitterness of the indignity put upon the army there, and of the injury it inflicts on the cause of the Union. Another contains a passage which I shall read. “I wish to say in addition that I have lived twenty-four years in Missouri, that I know the people well, have served them in various offices; and let me assure you, it is nonsense to try to save Missouri to the Union, and the institution of Slavery also. We must give up one or the other. Slavery ought to fall, and Missouri be saved. Fremont’s army struck terror into the Secessionists. He made them feel it by taking their goods and chattels. Let our armies proclaim freedom to the slaves of the Secessionists and the Rebellion will soon close. We can take care of the free negroes at a future day; give General Lane ten thousand men, and he would establish peace in Missouri in thirty days.” But, Sir, my special object now is, to exhibit wrong here at home rather than in distant Missouri. Brigadier-General Stone, the well-known commander at Ball’s Bluff, is adding to his disaster there by engaging in the surrender of fugitive slaves. He does this most successfully. If a fugitive slave is to be handed over to a Rebel, the General is easily victorious. Sir, beside my constant interest in this question, beside my interest in the honor of the national army, I have a special interest at the present moment, because Brigadier-General Stone sees fit to impose this vile and unconstitutional duty upon Massachusetts troops. The Governor of my honored State has charged me with a communication to the Secretary of War, treating it as an indignity to the men, and an act unworthy of the flag. I agree with the Governor; and when I ask your attention to this outrage, I make myself his representative, as well as my own.
