In the course of his labors, as Colonization Agent for Ohio, the writer, at an early day, found it necessary to examine the subject of African Missions. It was zealously urged, by many, that the Colonies of the Society, instead of being auxiliaries to the evangelization of the natives, presented an almost insuperable barrier to the spread of the Gospel in Africa. The facts ascertained, during the investigations, have been used, from time to time, in the Lectures delivered in different parts of the State, with general satisfaction to the friends of Colonization. The events of the last year or two in Africa, however, have been so marked, and the superiority of the missions in Liberia over all the others, so fully demonstrated, that the publication of the results has been urged as an act of justice to the American Colonization Society and to the Missions in the Republic.

In the preparation of the Lecture, none but the best authorities have been consulted, and the greatest care has been taken to avoid error. References to the sources of information are given in a few instances. Should any wish to verify the whole range of the facts stated, they will find them, mostly, in the following works and periodicals: Choule’s History of Missions, Reports of American Board of Commissioners for Foreign Missions, Missionary Herald, African Repository, and the works occasionally quoted in foot notes in the Lecture.
