WM. POLK. If any weight was due to human testimony, it was made probable, at least, if not certain, that the intentions of the promoters of the scheme were that it should be most kind to the black man, in all its direct action, and by its indirect influences, the precursor of the abolition of slavery; and if the society had fallen into a mistake, the colonists themselves had also fallen into the same; as in this address they say the scheme has proved successful. He would, therefore, conclude this second reason, by maintaining that he had sufficiently proved that the scheme had been productive of good, not only to the colored population, but also to the cause of universal freedom. The reasons he would now offer would be more general. And in bringing forward the third head of argument, he observed, that the uniform method which God had selected to civilize and enlighten mankind, and to carry through the world a knowledge of the arts and laws, with all the kindred blessings of civilization, was colonization. Amongst the first commands given by God to man, was to replenish and subdue the earth; and there was a striking fulness of meaning in the expression. While there seemed to exist in the whole human family an instinctive obedience to this command, God had so directed its manifestation, that he believed he might safely challenge any one to show him any one nation which had located the permanent seat of its empire in the native land of its inhabitants. Every nation had been a conquered nation; every people has been in turn enlightened from others, and in turn colonists again. This nation, which has reputed itself the most enlightened in the world, and far be it from him to controvert the opinion in their presence, might trace its superior enlightenment in part to the fact of its having been so much oftener conquered than any other, and the consequent greater mixture of nations among the inhabitants. Again, he observed, that God had kept several races of men distinct, from the time of Noah down to the present day; and in their mutual action upon each other, there was this extraordinary fact, that wherever the descendants of Shem had colonized a country occupied by the descendants of Japhet or Ham, they had extirpated those who were before them. When the descendants of Japhet conquered the descendants of Shem, they were extirpated before them; when the descendants of Shem conquered those of Japhet, the case was the same; and so of the descendants of Ham upon either. But when Japhet conquered Japhet there was no extirpation, and when Shem conquered Shem there was no extirpation, as also of Ham conquering Ham. Now as to the continent of Africa, if history taught any truth, they must roll back all its tide, or Africa was destined to be still farther colonized. As yet, the pestilence, like the flaming sword before the garden of the Lord, had kept the way hedged up, the white man and
