I was about to say, that I do not propose to go into the question of who was to blame for that repeal. I agree with gentlemen from the South, that there is no profit now in discussing the origin of our troubles--in inquiring who set the house on fire before we put on the water. Mr. CLAY:--Does the gentleman do justice to Mr. CLAY, when at one moment he says that Mr. CLAY held up the arms of the administration, strengthened the Executive, and aided the Government in putting down secession, and in the next, states that the compromise of 1850 was the cause of all our troubles, when it is well known that Mr. CLAY strongly favored that compromise? Mr. SMITH:--When I speak of the unhappy effect of the compromise measures of 1850, I ascribe no wrong motives to Mr. CLAY or any one else. If he approved that compromise, I have no doubt he did it in the full belief that it would be beneficial to the country. Experience has shown that he was mistaken. Saying this is doing no injustice to Mr. CLAY. I spoke only of effects. I spoke of the zeal and the energy with which the patriots and eminent statesmen of all parties of this country have been accustomed to come forward and sustain the administration when any necessity existed for doing so. Now let this Conference--let all true friends of the Union everywhere, with one voice, without attempting to place any section or any man in a false or disagreeable position, unite in one determined effort in behalf of the Union, and in an attempt to bring the rash and dangerous men who would seek the destruction of the Government back to a sense of duty. Let us address the country, let us show that we are devoted to the Union, far beyond any considerations of party or self; let us invoke the aid of all true and patriotic men; let us ask them to lay aside for the time all other considerations, and give themselves for the present to the country! The spirit of the old time is yet alive. We can call it out in more than its old strength and vigor, and it will save the country. Our private interests may suffer, but the great interests of the Union will be strengthened and preserved, and the Constitution, which has been our pride and strength, will not be dragged down into the great whirlpool of disunion. I appeal to the venerable and able men around me, who bear historic names--who have been themselves long connected with the Union and its Government, to join us in our struggle to save the Constitution. The views I have expressed may be chimerical. I have advanced them with no little diffidence, but I felt called upon to state them in the discharge of a duty I owe to a people who love and will make great sacrifices to save the Constitution and the Union.
