Such is a brief history of the agitation, as far as it has yet advanced. Now I ask, Senators, what is there to prevent its further progress, until it fulfils the ultimate end proposed, unless some decisive measure should be adopted to prevent it? Has any one of the causes, which has added to its increase from its original small and contemptible beginning until it has attained its present magnitude, diminished in force? Is the original cause of the movement--that slavery is a sin, and ought to be suppressed--weaker now than at the commencement? Or is the abolition party less numerous or influential, or have they less influence with, or less control over the two great parties of the North in elections? Or has the South greater means of influencing or controlling the movements of this Government now, than it had when the agitation commenced? To all these questions but one answer can be given: No, no, no. The very reverse is true. Instead of being weaker, all the elements in favor of agitation are stronger now than they were in 1835, when it first commenced, while all the elements of influence on the part of the South are weaker. Unless something decisive is done, I again ask, what is to stop this agitation, before the great and final object at which it aims--the abolition of slavery in the States--is consummated? Is it, then, not certain, that if something is not done to arrest it, the South will be forced to choose between abolition and secession? Indeed, as events are now moving, it will not require the South to secede, in order to dissolve the Union. Agitation will of itself effect it, of which its past history furnishes abundant proof--as I shall next proceed to show. It is a great mistake to suppose that disunion can be effected by a single blow. The cords which bound these States together in one common Union, are far too numerous and powerful for that. Disunion must be the work of time. It is only through a long process, and successively, that the cords can be snapped, until the whole fabric falls asunder. Already the agitation of the slavery question has snapped some of the most important, and has greatly weakened all the others, as I shall proceed to show. The cords that bind the States together are not only many, but various in character. Some are spiritual or ecclesiastical; some political; others social. Some appertain to the benefit conferred by the Union, and others to the feeling of duty and obligation.
