“Mr. Sumner spoke of the common ground where all who truly loved the country could stand. It was the Constitution as administered by Washington. The verdict of the people last November should be recognized without price or condition. “The President said he and Mr. Sumner must differ politically. “Mr. Sumner assured the President that the people of Massachusetts were attached to the Union; that real disunionists there might all be put in an omnibus; but Massachusetts could not be brought to sacrifice or abandon her principles, and in that he sincerely joined.” This interview was described by Mr. Sumner in one of his familiar letters to Governor Andrew, which is copied from the private files of the latter. WASHINGTON, February 3, 1861. MY DEAR ANDREW,--I saw the President yesterday. He was astonished to learn that the resolutions had not been acknowledged, and said that it should be done. Afterwards I said to him, “Mr. President, what else can we do in Massachusetts for the good of the country?” A pause. “Much, Mr. Sumner.” “What?” said I. “Adopt the Crittenden propositions,” said he. “Is that necessary?” said I. “Yes,” said he. To which I replied, “Massachusetts has not yet spoken directly; but I feel authorized to say, that, such are the unalterable convictions of her people, they would see their State sunk below the sea, and turned into a sand-bank, before they would adopt propositions acknowledging _property in men_, and disfranchising a portion of her population.” I think I was right. In God’s name stand firm! _Don’t cave_, Andrew! God bless you! CHARLES SUMNER. Save Massachusetts from any “surrender,” THE LEAST! C. S. The latter part of the letter alluded to reports that the Legislature was disposed to repeal or modify the well-known laws for the protection of Personal Liberty, passed originally as a defence against the Fugitive Slave Bill. Compromisers urged this surrender, particularly after the special call in the Crittenden propositions. At the request of anxious citizens at home, Mr. Sumner wrote to members of the Legislature against any such sacrifice, insisting, that, with the manifest determination of the South, it could do no good, while plainly the laws should be maintained for the sake of Liberty. His views were briefly expressed in a private letter to Hon. William Claflin, Chairman of the Republican State Committee, and President of the Massachusetts Senate.
