BOSTON, Thursday, May 27.

  At the session of the Universalist Moral Reform Society to-day, composed in part of leading Universalist Ministers, the following resolution was offered:

  Resolved. That we view with deep concern the present attitude of our country on the subject of Slavery—believing, as we do, that earnest efforts must be made for the overthrow of Slavery, or the just judgment of GOD will descend on our land,—and seeing with great pain a disposition on the part of those called statesmen to patch up Compromises, which merely hide but cannot cure the evil;—we feel called on as Christians to testify against the unrighteousness of Slavery, and to request our fellow Christians, of every sect, to unite with us in striving to break down that loathsome institution. . . .

  Rev. Mr. GAYLORD, of Lowell, said he supposed he could vote for the resolution; there was a time when he considered it bad policy for Universalists to take up this subject. While he had been settled at Nashville, Tennessee, he had been acquainted with just such characters as those in "Uncle Tom's Cabin." He could attest to the truth of the pictures drawn, and he was glad to find that the book was extensively read, especially at the South. He believed that it would do more good, than Garrison, Phillips, and such as they. The great question before the Convention was, whether or not the passage of the Compromise Measures were final on the subject. Many persons in Boston, and Christian men, too, were in favor of the Compromise Measures, because Mr. WEBSTER was in favor of them. It was only yesterday that CHARLES SUMNER introduced a memorial in Congress for the repeal of the Fugitve Slave Law. We, the Free Soil men, will do all that we can;; but we are met by bullying, and the whole influence of the South. Every fugitive slave sent back was but a new link to the chain which bound us to Slavery's car at the South, which was shaping the destinies of its opposition to progress and the cause of humanity. When he saw such men opposing the political Saviour of the age, KOSSUTH, he must object. He did not know but that it might check the spread of Universalism at the South. . . .
