There are none who will deny the truth of what is said of the present strength and influence of slavery, however much they may have deprecated its acquisition of power. There are none who think it practicable to assail it, successfully, by political action, in the States where it is already established by law. The struggle against the system, therefore, is narrowed down to an effort to prevent its extension into territory now free; and this contest is limited to the people who settle the territories. The question is thus taken out of the hands of the people at large, and they are cut off from all control of slavery both in the States and Territories. Hence it is, that the American people are considering the propriety of banishing this distracting question from national politics, and demanding of their statesmen that there shall no longer be any delay in the adoption of measures to sustain the Constitution and laws of our glorious Union, against all its enemies, whether domestic or foreign. The policy of adopting this course, may be liable to objection; but it does not appear to arise from any disposition to prove recreant to the cause of philanthropy, that a large portion of the people of the free States are desirous of divorcing the slavery question from all connection with political movements. It is because they now find themselves wholly powerless, as did the colonizationists, forty years since, in regard to emancipation, and are thus forced into a position of neutrality on that subject. A word on this point. The friends of colonization, in the outset of that enterprise, found themselves shut up to the necessity of creating a Republic on the shores of Africa, as the only hope for the free colored people--the further emancipation of the slaves, by State action, having become impracticable. After nearly forty years of experimenting with the free colored people, by others, colonizationists still find themselves circumscribed in their operations, to their original design of building up the Republic of Liberia, as the only rational hope of the elevation of the African race--the prospects of general emancipation being a thousand-fold more gloomy in 1859 than they were in 1817.
