In _South Carolina_ a large meeting was held at Charleston, on the 29th of July, of those who are in favor of co-operation for the purpose of resistance, and opposed to separate State action, under present circumstances. JOHN RUTLEDGE, Esq., was chosen chairman. A letter was read from Hon. LANGDON CHEVES, approving the object of the meeting, asserting the right of secession, but affirming that it would not be "a moral or social one on the part of one Southern State in reference to sister States at the South." He thought that South Carolina ought to secede, but not alone; and that a union in favor of secession would take place. A letter from Hon. J. L. ORR was also read, reflecting in severe terms upon the spirit manifested by the "actionists" toward the "co-operationists," as affording a "beautiful commentary" on their desire "that harmony may be preserved throughout the State;" which was "the harmony which the wolf gives the lamb." He said, that "when an issue could be made, these self-appointed leaders would be routed, overwhelmed by the voice of the people, rebuking their temerity." The people of the mountain districts "were nearly all ready for resistance to the Clay Compromise; but they were yet to be convinced that they had more courage and patriotism than their Georgia and North Carolina neighbors." A series of resolutions was passed, declaring that the measures of the Federal Government, taken in connection with the manifestations of feeling at the North, showed a settled purpose to deprive the Southern States of their rank as equals in the Confederacy, and tended to the abolition of slavery and the establishment of a consolidated government; and that the time had therefore come when the Union ought to be dissolved, and a Southern Confederacy formed; but that they would still willingly give trial to any scheme proposed by the South, short of dissolution, for reinstating them in their rights. That, as the subject of controversy concerned all the Southern States as much as South Carolina, the true policy to be observed was concert of action; and that separate State action was to be deprecated as tending to alienate the other States and thus "prevent the formation of a Southern Confederacy;" delay would insure the co-operation of the other States; while separate action would place South Carolina in the position of a foreign country; in which case the laws preventing the introduction of slaves into the United States would subject her "practically to the Wilmot Proviso in its worst form." Separate action would be "not only abortive as a measure of deliverance, but if not utterly suicidal in its effects, in the highest degree dangerous to the stability of our institutions." The right of secession was affirmed to be essential to State sovereignty. The approaching State Convention was invoked to take measures to bring about a Southern Confederacy; and, meanwhile, to define the relation which South Carolina should hold to the Federal
