Under the most favorable circumstances possible for the experiment of self-government, with every possible inducement to preserve our country, we must not give it up. The years of civil war which will succeed dismemberment of the Union will cause true men to seek refuge and security, from military despotism, in some other country. Some Caesar or Napoleon will spring from the vortex of revolution and war, and with his sword cleave his way to supreme command. If all history is not a failure, and if mankind are now what they have always been, such will be the fate of free government in the United States, in the event of war. Shall we bring such a catastrophe upon us to vindicate the Chicago Platform? No! the American people will rise in their omnipotence and trample into dust the man who dared to put in jeopardy this Union, in order to maintain such demagogism. Away with parties and platforms and every thing else which would obstruct the free and patriotic efforts now making for the salvation of the Union. It shall not be destroyed. I tell you, friends, I am going to stand right in the way. You shall not go home; you shall never see your wives and families again, until you have settled these matters, and saved your good old country, if I can help it. Spread aloft the banner of stripes and stars, let the whole country rally beneath its glorious folds, with no other slogan on their lips but the unanimous cry, THE UNION, IT MUST BE PRESERVED! Mr. GRANGER:--New Jersey has addressed New York as though she supposed the delegation from that State to be united in its opinions, and its action. Let me set the gentleman himself and the Conference right on that point at the commencement. The members composing that delegation do not agree; very far from it. The vote of that delegation hitherto has been determined by a majority only; a majority reduced to the very smallest point possible now, since the delegation is full. It may be said that New York voted at the last Presidential election against us by a majority of fifty thousand; but let me assure you that if the noble propositions of the majority of your committee, which I read for the first time yesterday, could be submitted to them, the people of New York would adopt them by even a larger majority. These _are_ noble propositions; they are worthy the eminent and patriotic committee from which they have emanated. They present a fair and equitable basis for the adjustment of our difficulties; they are a shield and a sure defence against the dangers which threaten us. They are such as the people expect and such as they want. They know that the politicians who have brought the country to the verge of ruin can be trusted no longer. The time has come when they must act for themselves. Be assured, gentlemen, they will do so.
