The Africans when first brought into this country were not a whit better in morals, and were greatly inferior in intellect to the ancient inhabitants of Canaan. And, although it be admitted that they have improved, the facts given clearly prove that they are still incompetent to self-government. They are, therefore, no more entitled to the right of political sovereignty than the Canaanites were. But more than this, the Canaanites did not materially differ from the Jews in their physical condition. There were no physical reasons against amalgamation. Intermarriage, it is true, was forbidden, but it was for reasons growing out of their heathen state alone. Whilst that state should last, the common interests of each in civilization forbade such social equality; but this cause out of the way, the Canaanites could be absorbed and lost in the stream of posterity. But not so with the African, as we have shown. He is destined to exist as a separate people. We do not say he shall not, but he cannot to any material extent amalgamate with the Caucasian race. If, therefore, it was proper for the Jews to make slaves of the Canaanites, for a much stronger reason it is now right for us to retain the African in a similar state, and until such time as Providence shall--if ever--open the door for his return to his fatherland. On the general question, Is the system of domestic government existing amongst us, and involving the abstract principle of slavery, justified by the circumstances of the case, and therefore right? we reach an affirmative conclusion, for the reasons: I. That the Africans are a distinct race of people, who cannot amalgamate to any material extent with the whites, and who, therefore, must continue to exist as a separate class. II. That they are, as a class, decidedly inferior to the whites in point of intellectual and moral development, so much so as to be incompetent to self-government. Although they have shared largely in the progress of civilization, they have not reached this point. The proof is: 1. Such is the almost universal opinion of the most intelligent and pious communities throughout the whole Southern country, who certainly are well acquainted with their character and capabilities, and therefore fully competent to judge in their case. 2. The experiments at domestic colonization which have been made in this country prove it. 3. The experiments in the case of the free colored population spread through the country are equally in proof. 4. The colonization experiment on the coast of Africa is still more conclusive. III. That domestic slavery is the appropriate form of government for a people in such circumstances, is fully exemplified by the Divine procedure in the case of the heathen subdued by the ancient Israelites. We infer:
