How then can the public mind be assured that to emancipate the enslaved race, to confer on them all the moral rights of humanity, does not involve by any necessity or even remote probability, either an internecine war of races on our own soil, or the fusion of the two races into one homogeneous people? One answer, which satisfies many, is, the freedmen must be colonized in some unoccupied region of the earth, where they may be separated from the white man, and build up for themselves an independent and homogeneous nationality. I have no controversy with this proposed solution of the difficulty, or with the excellent men who are advocating and promoting it, with an earnest patriotism worthy of all honor. But I have grave doubts of the adequacy of this solution to meet the momentous exigencies of the present crisis. At least, I feel no necessity of resting the whole cause upon it, when there is another solution at hand, which certainly is adequate, furnished by the very laws of nature which the Creator has established, and so certain in its operation, that we have only to strike the fetters from the limbs of the poor slave, and recognize his manhood, and God will take care of the rest, and protect our country from the evils we have so much dreaded. That solution is found in a great law of population. It is necessary, therefore, that I should state this law, and prove its reality, and its adequacy to meet all the necessities of the case in hand. Whenever two peoples, one of which is little removed from barbarism, and the other having the full strength of a mature civilization, are placed in juxtaposition with each other, on terms of free labor and free competition, the stronger will always either amalgamate itself with the weaker, or extinguish it. In the former case, civilization undergoes an eclipse, almost an extinction. The homogeneous people resulting from such a union, occupies a position in the scale of civilization much nearer to that of their barbarous than that of their civilized parents. Numerous and conclusive examples of this have occurred in the progress of the French, Spanish, and Portuguese colonies in proximity to the various native tribes of this continent. They have generally amalgamated freely with their savage neighbors; and a deep eclipse of civilization has in every instance resulted. When that eclipse is to end, we have not the foresight to determine.
