The gentleman from Connecticut [Mr. FERRY] will recollect his declaration that some of us may live to see the day when this Confederacy may consist of fifty sovereignties; and when that day comes, it will be their duty, according to the principles of the Republican party, to change the Constitution and to abolish slavery. And yet gentlemen seem to wonder that the people of the South are talking about new guards for their safety. Sir, the maxim laid down by Jefferson, that governments should not be abolished for light or transient causes, is most true; but no less true is the maxim that a people are always disposed to endure evils so long as they are endurable, rather than right themselves by abolishing the forms of which they are accustomed. Sir, what may be the action of Louisiana, in any contingency that may arise, it is not for me to state. I believe that the people of my State have too much at stake to attempt to change their present institutions, or to make any new arrangement for light or transient causes. We have an immense wealth, a vast commerce, a city trading with all the States of the Union, whose forests of masts, from which float the flags of all nations, denote that her commerce is coextensive with the globe. The levee of her commercial emporium literally trembles, in a frontage of nine miles, beneath the superincumbent masses of merchandise. Reluctantly, most reluctantly, would that people take any steps which by possibility could involve us in civil war and commotion; and great, indeed, must have been their apprehension when they adopted, in convention, March 15, 1860, the following resolution: "That, in case of the election of a President on the avowed principles of the Black Republican party, we concur in the opinion that Louisiana should meet in council her sister slaveholding States, to consult as to the means of future protection." I have no idea that I am mistaken, when I state that no action will be taken under that resolution, except on the most mature deliberation. But, sir, whenever the people of Louisiana believe that their institutions are in danger, and that it is the deliberate purpose of those who may get control of the Government to spread over them that dark and benighted pall which hangs like an incubus over the Central and South American republics and the West India Islands that have emancipated their slaves, I tell you they will act, and act effectually, too, for their protection and security. And whatever course the majority of her people may choose to take, her sons will sustain it with their lives, their fortunes, and their sacred honor. THOS. MCGILL, Print.
