This great result was without the capture of a single vessel. It was enough that at last we were in earnest. Judges and arbitrators found themselves without employment, when, in an appropriation bill, of March 3, 1869, Congress called on the President, with the consent of Great Britain, to terminate that part of the treaty requiring mixed courts and their annual outlay.[306] This was done by treaty between the two powers, signed at Washington, June 3, 1870; so that the mutual right of search for the suppression of the slave-trade alone remained. ENFORCEMENT OF EMANCIPATION IN THE DISTRICT. RESOLUTION AND REMARKS IN THE SENATE, APRIL 28, 1862. April 18th, Mr. Sumner offered the following resolution, which was considered by unanimous consent, and adopted. “_Resolved_, That the Secretary of the Interior be requested to furnish, for the use of the Senate, a list of all persons residing in the District of Columbia who appear in the returns of the last census as owners of slaves, indicating the number claimed to be owned by each person, with the classification of their ages according to the returns.” April 28th, the Secretary of the Interior accompanied the return with the suggestion, that, as it exposed the private affairs of individuals, it was questionable “whether it would be proper to print it for circulation.” On hearing this communication read at the desk, Mr. Sumner moved its reference to the Committee on the District of Columbia, and remarked:-- MR. PRESIDENT,--In offering the resolution, I felt that I was doing good service to the Commissioners appointed to carry out our recent measure of Emancipation, and I felt also that I was helping to correct possible abuses in anticipation of its operation. I have been sorry to hear of efforts during the last few weeks to run able-bodied slaves out of the District. Slavery is often called a patriarchal institution, and I am anxious to see how many of the patriarchs, in avoidance of the action of Congress, have transported slaves beyond the reach of its beneficent power. Such an outrage ought to be exposed. I confess that I find no good reason for delicacy towards persons so guilty. I am sure that freedom and truth will be gainers, when such conduct is laid bare. I cannot doubt that the object proposed is important. These statistics should be brought before the Senate, if not before the country. They will be needed by the Commissioners, and I am sure they will do something to illustrate the character of Slavery. The motion was agreed to. THE CONDUCT OF OUR GENERALS TOWARDS FUGITIVE SLAVES. SPEECH IN THE SENATE, ON A RESOLUTION OF INQUIRY, MAY 1, 1862.
