The seven seceding States (South Carolina, Mississippi, Georgia, Florida, Alabama, Louisiana and Texas,) as shown by data previously given, organized their Provisional Government, with Jefferson Davis, the most radical secession leader, as President; and Alex. H. Stephens, the most conservative leader, as Vice-President. The reasons for these selections were obvious; the first met the views of the cotton States, the other example was needed in securing the secession of other States. The Convention adopted a constitution, the substance of which is given elsewhere in this work. Stephens delivered a speech at Savannah, March 21st, 1861, in explanation and vindication of this instrument, which says all that need be said about it: “The new Constitution has put at rest forever all the agitating questions relating to our peculiar institutions—African slavery as it exists among us—the proper status of the negro in our form of civilization. _This was the immediate cause of the late rupture and present revolution. Jefferson, in his forecast, had anticipated this as the ‘rock upon which the old Union would split.’_ He was right. What was conjecture with him, is now a realized fact. But whether he fully comprehended the great truth upon which that rock stood and stands, may be doubted. The prevailing ideas entertained by him and most of the leading statesmen at the time of the formation of the old Constitution, were that the enslavement of the African was in violation of the laws of nature: that it was wrong in principle, socially, morally, and politically. It was an evil they knew not well how to deal with, but the general opinion of the men of that day was, that somehow or other, in the order of Providence, the institution would be evanescent and pass away. This idea, though not incorporated in the Constitution, was the prevailing idea at the time. The Constitution, it is true, secured every essential guarantee to the institution while it should last, and hence no argument can be justly used against the constitutional guarantees thus secured, because of the common sentiment of the day. Those ideas, however, were fundamentally wrong. They rested upon the assumption of the equality of races. This was an error. It was a sandy foundation, and the idea of a government built upon it; when the ‘storm came and the wind blew, it fell.’
