If coming events should render necessary the convocation of the Southern Convention, I shall endeavor to compose the representation of Louisiana of her ablest and most prudent men, if the power shall be vested in me to appoint them. However, I presume the Legislature will adopt some other course in the appointments. The recommendations of such a body assembled in such a crisis must necessarily carry great weight, and if subsequently ratified and adopted by each State by proper authority, will present the South in united and harmonious action. I have the honor to be your Excellency's ob't serv't THOS. O. MOORE. [Sidenote] MS. Ibid. MACON, Oct. 26, 1860. His EXCELLENCY Gov. GIST. DEAR SIR: Your letter of Oct. 5 was handed me by General Gist. Having but few moments to reply, I write this more to acknowledge its receipt than to reply to its contents. Our friends in this State are willing to do anything they may have the power to do to prevent the State from passing under the Black Republican yoke. Our people know this, and seem to approve such sentiments, yet I do not believe Mississippi can move alone. I will call our Legislature in extra session as soon as it is known that the Black Republicans have carried the election. I expect Mississippi will ask a council of the Southern States, and if that council advise secession, Mississippi will go with them. If any State moves, I think Mississippi will go with her. I will write at length from Jackson. Yours respectfully, JOHN J. PETTUS. [Sidenote] MS. Confederate Archives. EXECUTIVE DEPARTMENT, MILLEDGEVILLE, GA., Oct. 31, 1860. His EXCELLENCY W.H. GIST.
