The rivers I have dwelt upon, are surrounded with fertile lands and a numerous population, and may be navigated a considerable distance into the interior country; and by reducing all operations to one well adapted system, under the guidance of experience, moderation, and wisdom, I am firmly persuaded that success will be the result. What I have said relative to the present state of the natives of Africa, may tend to demonstrate the nature of the opposition, which civilization has to guard against, and the barbarism it has to contend with. The condition of a free Negro in Africa is easy and contented, and the class of slaves attached to them, are satisfied with their fate. They only are to be lamented, who are procured from condemnation, either for real or imaginary crimes, or who are taken in war; and it is from this class that slaves are procured by other nations. It is a remarkable circumstance, that the major part of these unhappy creatures come from the interior, and that the maritime places which have had intercourse with Europeans, afford only a small number of slaves; and I am persuaded, abominable as the slave trade may be considered, and disgraceful as it is, that it has saved many human beings from a premature and barbarous death. I am also firmly of opinion, that it is only by a _gradual abolition_, and a rational system to civilize the inhabitants of Africa, that this detested traffic can be effectually abolished. A rational philosophy and humanity, should first have submitted to political necessity, and have commenced experiment upon practicable theories, while the sacred rights of property should have been regarded, and well considered. This opinion may perhaps subject me to the animadversion of many worthy individuals; but I beg to assure them, that I am as zealous an abolitionist as any among my fellow subjects, although I widely differ from many of them, as to the means of effecting a measure, that embraces so large a portion of the human race; and I should contradict the conviction of my own mind, were I to utter any other opinion. Rectitude of intention, a lively interest in the condition of the African, and a deep impression of the importance of this country to Great Britain, in a commercial point of view, have actuated me in obtruding myself upon the public; and before I take my leave, I earnestly entreat a deliberate investigation of the imperfect system of operation, I have recommended in the foregoing pages. If I have not been sufficiently perspicuous, I trust the shafts of criticism will be enfeebled by the consideration, that a commercial education and pursuit cannot claim a title to literary acquirements; but if in any instance I meet the judgment of a discerning public, and my suggestions excite more competent endeavours, I shall feel the highest pleasure, and satisfaction.
