There are some who think that anything for Slavery is constitutional, but nothing for Freedom. With me the opposite rule prevails, and I venture to say that any other rule must bring discredit upon a country calling itself a Commonwealth. I trust, also, that the people of Kansas will stand firm, and that, if need be, they will know how to die for Freedom. Do any sigh for a Thermopylæ? They have it in Kansas, for there is to be fought the great battle between Freedom and Slavery,--by the _ballot-box_, I trust; but I do not forget that all who destroy the ballot-box madly invoke the _cartridge-box_. With a farewell to my country, as I seek a foreign land, hoping for health long deferred, I give my last thoughts to suffering Kansas, with devout prayers that the ruffian Usurpation which now treads her down may be peaceably overthrown, and that she may be lifted into the enjoyment of freedom and repose. Ever faithfully yours, CHARLES SUMNER. P. S. I entrust this to the pilot, and hope it may reach you. JAMES REDPATH, Esq. INVITATION TO DINNER BY AMERICAN MERCHANTS IN PARIS.
