I have long foreseen and often forewarned my countrymen of the now impending danger. This does not proceed solely from the claim on the part of Congress or the Territorial legislatures to exclude slavery from the Territories, nor from the efforts of different States to defeat the execution of the fugitive-slave law. All or any of these evils might have been endured by the South without danger to the Union (as others have been) in the hope that time and reflection might apply the remedy. The immediate peril arises not so much from these causes as from the fact that the incessant and violent agitation of the slavery question throughout the North for the last quarter of a century has at length produced its malign influence on the slaves and inspired them with vague notions of freedom. Hence a sense of security no longer exists around the family altar. This feeling of peace at home has given place to apprehensions of servile insurrections. Many a matron throughout the South retires at night in dread of what may befall herself and children before the morning. Should this apprehension of domestic danger, whether real or imaginary, extend and intensify itself until it shall pervade the masses of the Southern people, then disunion will become inevitable. Self-preservation is the first law of nature, and has been implanted in the heart of man by his Creator for the wisest purpose; and no political union, however fraught with blessings and benefits in all other respects, can long continue if the necessary consequence be to render the homes and the firesides of nearly half the parties to it habitually and hopelessly insecure. Sooner or later the bonds of such a union must be severed. It is my conviction that this fatal period has not yet arrived, and my prayer to God is that He would preserve the Constitution and the Union throughout all generations. But let us take warning in time and remove the cause of danger. It can not be denied that for five and twenty years the agitation at the North against slavery has been incessant. In 1835 pictorial handbills and inflammatory appeals were circulated extensively throughout the South of a character to excite the passions of the slaves, and, in the language of General Jackson, "to stimulate them to insurrection and produce all the horrors of a servile war." This agitation has ever since been continued by the public press, by the proceedings of State and county conventions and by abolition sermons and lectures. The time of Congress has been occupied in violent speeches on this never-ending subject, and appeals, in pamphlet and other forms, indorsed by distinguished names, have been sent forth from this central point and spread broadcast over the Union.
