In estimating the strength of a cause, we are obliged to take into account the actually existing reasons in favor of its support. Delusion, founded on a fictitious cause of complaint, is but a weak basis for revolution. It may have an apparent strength to precipitate revolt, but has no power of endurance. There is a reflection that comes through calamity and suffering that rises superior to sophistry in the most common minds. If not already, this will soon be the case with the whole Southern population. The slaveholder and the man of trade and commerce who feared the tumult, and would have avoided it, will have seen their apprehensions turned into the fulfillment of prophecy. The non-slave-holding farmer, mechanic, or laborer, will be made to see clearly that his interest did not lie on the side of treason. The political adventurer who planned the conspiracy, is already brought to see the fallacy of his dream. He may now consider the incongruous materials of Southern population. He may view that population in classes. He may contemplate it through the medium of its natural motives of fidelity to the Government on the one hand, and of its artificial delusion on the other. He may now go to the bottom of Southern society, and find in its conflicting elements the antagonistic motives that render the plans of treason abortive. These will be sure to continue, and sure to strengthen on the side of fidelity to the National Government. When the South is made a solid, compact unit in political motive, it will become so, disarmed of all purposes of treason.
