ratio, as they stretch away towards the North Star from the frontier of Slavery?  These questions must suggest their sufficient answer to thousands of hearts, and be preparing the way for the insurrection of which the slaveholders stand in the deadliest fear,—­that of the whites at their gates, who can do with them and their institutions what seems to them good, when once they know their power, and choose to put it forth.  The unity of interest of the non-slaveholders of the South with the people of the Free States is perfect, and it must one day combine them in a unity of action.

The exact time when the millions of the North and of the South shall rise upon this puny mastership, and snatch from its hands the control of their own affairs, we cannot tell,—­nor yet the authentic shape which that righteous insurrection will take unto itself.  But we know that when the great body of any nation is thoroughly aroused, and fully in earnest to abate a mischief or to right a wrong, nothing can resist its energy or defeat its purpose.  It will provide the way, when its will is once thoroughly excited.  Men look out upon the world they live in, and it seems as if a change for the better were hopeless and impossible.  The great statesmen, the eminent divines, the reverend judges, the learned lawyers, the wealthy landholders and merchants are all leagued together to repel innovation.  But the earth still moves in its orbit around the sun; decay and change and death pursue their inevitable course; the child is born and grows up; the strong man grows old and dies; the law of flux and efflux never ceases, and lo! ere men are aware of it, all things have become new.  Fresh eyes look upon the world, and it is changed.  Where are now Calhoun, and Clay, and Webster?  Where will shortly be Cass, and Buchanan, and Benton, and their like?  Vanished from the stage of affairs, if not from the face of Nature.  Who are to take their places?  God knows.  But we know that the school in which men are now in training for the arena is very different from the one which formed the past and passing generations of politicians.  Great ideas are abroad, challenging the encounter of youth.  Angels wrestle with the men of this generation, as with the Patriarch of old, and it is our own fault if a blessing be not extorted ere they take their flight.  Principles, like those which in the earlier days of the republic elevated men into statesmen, are now again in the field, chasing the policies which have dwarfed their sons into politicians.  These things are portentous of change,—­perhaps sudden, but, however delayed, inevitable.
