I have now, Senators, done my duty in ex-pressing my opinions fully, freely and candidly, on this solemn occasion. In doing so, I have been governed by the motives which have governed me in all the stages of the agitation of the slavery question since its commencement. I have exerted myself, during the whole period, to arrest it, with the intention of saving the Union, if it could be done; and if it could not, to save the section where it has pleased Providence to cast my lot, and which I sincerely believe has justice and the Constitution on its side. Having faithfully done my duty to the best of my ability, both to the Union and my section, throughout this agitation, I shall have the consolation, let what will come, that I am free from all responsibility. [Illustration: Daniel Webster] DANIEL WEBSTER, OF MASSACHUSETTS. (BORN, 1782, DIED, 1852.) ON THE CONSTITUTION AND THE UNION; SENATE OF THE UNITED STATES, MARCH 7, 1850. MR. PRESIDENT: I wish to speak to-day, not as a Massachusetts man, nor as a northern man, but as an American, and a member of the Senate of the United States. It is fortunate that there is a Senate of the United States; a body not yet moved from its propriety, nor lost to a just sense of its own dignity and its own high responsibilities, and a body to which the country looks, with confidence, for wise, moderate, patriotic, and healing counsels. It is not to be denied that we live in the midst of strong agitations and are surrounded by very considerable dangers to our institutions and government. The imprisoned winds are let loose. The East, the North, and the stormy South combine to throw the whole sea into commotion, to toss its billows to the skies, and disclose its profoundest depths. I do not affect to regard myself, Mr. President, as holding, or fit to hold, the helm in this combat with the political elements; but I have a duty to perform, and I mean to perform it with fidelity, not without a sense of existing dangers, but not without hope. I have a part to act, not for my own security or safety, for I am looking out for no fragment upon which to float away from the wreck, if wreck there must be, but for the good of the whole, and the preservation of all; and there is that which will keep me to my duty during this struggle, whether the sun and the stars shall appear for many days. I speak to-day for the preservation of the Union. "Hear me for my cause." I speak to-day out of a solicitous and anxious heart, for the restoration to the country of that quiet and that harmony which make the blessings of this Union so rich, and so dear to us all. These are the topics that I propose to myself to discuss; these are the motives, and the sole motives, that influence me in the wish to communicate my opinions to the Senate and the country; and if I can do any thing, however little, for the promotion of these ends, I shall have accomplished all that I expect.
