Mr. President, I have thus stated the reasons of my dissent to the doctrines which have been advanced and maintained.  I am conscious of having detained you and the Senate much too long.  I was drawn into the debate with no previous deliberation, such as is suited to the discussion of so grave and important a subject.  But it is a subject of which my heart is full, and I have not been willing to suppress the utterance of its spontaneous sentiments.  I cannot, even now, persuade myself to relinquish it, without expressing, once more my deep conviction, that, since it respects nothing less than the union of the States, it is of most vital and essential importance to the public happiness.  I profess, sir, in my career hitherto, to have kept steadily in view the prosperity and honor of the whole country, and the preservation of our Federal Union.  It is to that Union we owe our safety at home, and our consideration and dignity abroad.  It is to that Union that we are chiefly indebted for whatever makes us most proud of our country.  That Union we reached only by the discipline of our virtues in the severe school of adversity.  It had its origin in the necessities of disordered finance, prostrate commerce, and ruined credit.  Under its benign influences, these great interests immediately awoke, as from the dead, and sprang forth with newness of life.  Every year of its duration has teemed with fresh proofs of its utility and its blessings; and although our territory has stretched out wider and wider, and our population spread farther and farther, they have not outrun its protection or its benefits.  It has been to us all a copious fountain of national, social, and personal happiness.

I have not allowed myself, sir, to look beyond the Union, to see what might lie hidden in the dark recess behind.  I have not coolly weighed the chances of preserving liberty when the bonds that unite us together shall be broken asunder.  I have not accustomed myself to hang over the precipice of disunion, to see whether, with my short sight, I can fathom the depth of the abyss below; nor could I regard him as a safe counsellor in the affairs of this Government, whose thoughts should be mainly bent on considering, not how the Union may be best preserved, but how tolerable might be the condition of the people when it should be broken up and destroyed.  While the Union lasts we have high, exciting, gratifying prospects spread out before us, for us and our children.  Beyond that I seek not to penetrate the veil.  God grant that in my day at least that curtain may not rise!  God grant that on my vision never may be opened what lies behind!  When my eyes shall be turned to behold for the last time the sun in heaven, may I not see him shining on the broken and dishonored fragments of a once glorious Union, on States dissevered, discordant, belligerent; on a land rent with civil feuds, or drenched, it may be, in fraternal blood!  Let their last feeble and lingering glance rather behold the gorgeous
