Disunion is a crime against every thing. Above all, it is a crime against GOD. Christians, pause and reflect. Let me entreat you to help us save this country from disunion. I speak earnestly. We Pennsylvanians are upon the border. Our soil must be the battle ground. Upon us will the heavy trouble fall. Once more I say, let us trust the people. They are always right. They will do something; and honest men, sincere men, tell us that unless something is done, the border slave States cannot be retained in the Union. I am not here as a party man, but as an American citizen, and a citizen of Pennsylvania. I am here to perform my duty to the whole country, if I can find out what that duty is. Our friends say there is great apprehension at the South that the Republican party meditates unconditional interference with Southern rights. I do not believe for a moment that there is any ground for such an apprehension. But, nevertheless, it exists. Acting upon it, several States have withdrawn from the Union. We must deal with it in the best way we can. If we can satisfy our southern brethren, in the name of peace let us do it. I labored for the election of Mr. LINCOLN, but I never understood that hostility to slavery was the leading idea in the platform of his party. Pennsylvania had other interests--other reasons very powerful, for supporting him. There was the repeal of the Missouri Compromise--ruinous discriminations in the Tariff--the corruption of the Government--the villanous conduct of its high officers; these and other considerations gave Mr. LINCOLN more strength in Pennsylvania than the slavery question. There are sentiments and opinions at the North that must be respected. There are sentiments and opinions at the South that must be respected; but there are no differences that cannot be honorably adjusted. The only practicable way that I can discover is to adopt the plan reported by the committee, and secure its submission to the people. How can we do greater honor to this glorious day, which gave the immortal WASHINGTON to his country and to the world, than by marking it on the calendar as the day that secured the safety and perpetuity of the American Union? Mr. SUMMERS:--The Committee on Credentials have examined the case of Mr. J.C. STONE, who is commissioned as a delegate from Kansas, and are of opinion that he is duly accredited. Mr. FIELD:--I understand that he was appointed by Mr. BEEBE, the Secretary of the Territorial Government. Mr. CLAY:--There is a provision in the Kansas Act authorizing the Secretary to perform all the duties of the Governor in his absence. Mr. BROCKENBROUGH:--I represent an old and honored Commonwealth. I speak, remembering the maxing that "a soft answer turneth away wrath." But I should disregard my duty if I did not reply to what was said a few days ago, in arraignment--in unfair and improper arraignment, of Virginia.
