great party was organized for the purpose of obtaining the administration of the Government, with the avowed object of using its power for the total exclusion of the slave States from all participation in the benefits of the public domain acquired by all the States in common, whether by conquest or purchase; of surrounding them entirely by States in which slavery should be prohibited; of thus rendering the property in slaves so insecure as to be comparatively worthless, and thereby annihilating in effect property worth thousands of millions of dollars. This party, thus organized, succeeded in the month of November last in the election of its candidate for the Presidency of the United States.
In the meantime, under the mild and genial climate of the Southern States and the increasing care and attention for the well-being and comfort of the laboring class, dictated alike by interest and humanity, the African slaves had augmented in number from about 600,000, at the date of the adoption of the constitutional compact, to upward of 4,000,000. In moral and social condition they had been elevated from brutal savages into docile, intelligent, and civilized agricultural laborers, and supplied not only with bodily comforts but with careful religious instruction.

With interests of such overwhelming magnitude imperiled, the people of the Southern States were driven by the conduct of the North to the adoption of some course of action to avert the danger with which they were openly menaced. With this view the Legislatures of the several States invited the people to select delegates to conventions to be held for
