The Resolutions of the Oxford Council, appended to this address, emanate from colored men of more than ordinary intelligence. None of them are advocates of Colonization, but they are capable of taking a comprehensive view of the questions involved in the enslavement of their race. They are now convinced, that unless the free colored people assume a position enabling them to engage largely in tropical cultivation, slavery, by retaining the monopoly of the supply of tropical products, must continue to possess the power of extending itself at will. The only question, with them, is, Where can the free colored people become the most efficient agents in the deliverance and elevation of their race? They have resolved, therefore, to collect information from Africa, while others are investigating South America. The slavery question, in their opinion, is now assuming a position in which attention must be more fully directed to its economical aspects. Moral considerations, they perceive, are powerless in arresting its progress. The cumulative demands of commerce, for tropical productions, are stimulating slavery in an unprecedented degree; and unless free labor can be enlisted in tropical cultivation, it must continue to extend until the whole of tropical America submits to its sway. As only a part of the towns and congregations in Ohio could be visited during a single year; as the opposition to Colonization had been more extended, and its agencies more perfectly systematized here than, perhaps, in any other State; as it was impossible to obtain audiences, generally, to hear lectures, except on the Sabbath, when the secular aspects of the subject could not be discussed; and, as the people of African descent, almost to a man, were bitterly opposed to Liberia, and willing to believe every ill report its enemies put into circulation; the Agent found it necessary, at an early period of his labors, to resort to his pen, as a means of correcting public sentiment, and disseminating truth among the colored people. The fifth and last document of this kind is forwarded herewith, and commended to your attention. Its object, mainly, is to demonstrate the necessity of Colonization as an auxiliary to missions in Africa; to show what colored men, themselves, have accomplished for the elevation of their race; and to afford the pastors of congregations a brief outline of facts to lay before their people.
