I have no desire to precipitate the debate on this important question, under which the country already shakes from side to side, and which threatens to scatter from its folds civil war. Nor, indeed, am I disposed to enter upon it, until I have the opportunity of seeing in print the elaborate documents which have been read to-day. But I cannot allow the subject to pass away, even for this hour, without repelling at once, distinctly and unequivocally, the assault which has been made upon the Emigrant Aid Company of Massachusetts. That Company has done nothing for which it can be condemned under the laws and Constitution of the land. These it has not offended in letter or spirit,--not in the slightest letter, nor in the remotest spirit. It is true, it has sent men to Kansas; and had it not a right to send them? It is true, I trust, that its agents love Freedom and hate Slavery; and have they not a right to do so? Their offence has this extent, and no more. Sir, to the whole arraignment of that Company, in the report of the Committee on Territories, I now for them plead, “Not guilty!” and confidently appeal to the country for that honorable acquittal which is due to their patriot services. The outrages in Kansas are vindicated or extenuated by the alleged misconduct of the Emigrant Aid Company. Very well, Sir; a bad cause is naturally staked on untenable ground. You cannot show the misconduct. Any such allegation will fail. And you now begin your game with loaded dice. UNION TO SAVE KANSAS, AND UNION TO SAVE OURSELVES. LETTER TO A NEW YORK COMMITTEE, APRIL 28, 1856. SENATE CHAMBER, April 28, 1856. DEAR SIR,--I cannot be at your proposed meeting, where are to assemble the patriotism, intelligence, and wealth of the metropolis; but I recognize its importance, and cry to it _God-speed!_ The work before us is plain. Kansas must be saved from a tyrannical usurpation, under which Slavery has been forcibly established on Free Soil. This is the special object of labor to which we are summoned by every consideration of regard for that distant Territory, and also by every sentiment of love for our common country. But this can be done only by her immediate welcome into the Union, under her present Constitution, as a Free State,--of course without recognition of the usurping Tyranny. Upon this we must insist, as the means essential to the end.
