One of the principal objects which Her Britannic Majesty’s Government had always in view in these African expeditions was the abolition of the slave-trade. This, too, was zealously advocated by the late Mr. Richardson, and, I trust, has been as zealously carried out by myself whenever it was in my power to do so, although, as an explorer on a journey of discovery, I was induced, after mature reflection, to place myself under the protection of an expeditionary army, whose object it was to subdue another tribe, and eventually to carry away a large proportion of the conquered into slavery. Now, it should always be borne in mind that there is a broad distinction between the slave-trade and domestic slavery. The foreign slave-trade may, comparatively speaking, be easily abolished, though the difficulties of watching over contraband attempts have been shown sufficiently by many years’ experience. With the abolition of the slave-trade all along the northern and south-western coast of Africa, slaves will cease to be brought down to the coast; and in this way a great deal of the mischief and misery necessarily resulting from this inhuman traffic will be cut off. But this, unfortunately, forms only a small part of the evil. There can be no doubt that the most horrible topic connected with slavery is slave-hunting; and this is carried on not only for the purpose of supplying the foreign market, but, in a far more extensive degree, for supplying the wants of domestic slavery. Hence it was necessary that I should become acquainted with the real state of these most important features of African society, in order to speak clearly about them; for with what authority could I expatiate on the horrors and the destruction accompanying such an expedition, if I were not speaking as an eye-witness? But having myself accompanied such a host on a grand scale, I shall be able to lay before the public a picture of the cheerful comfort, as well as the domestic happiness, of a considerable portion of the human race, which, though in a low, is not at all in a degraded state of civilization, as well as the wanton and cruel manner in which this happiness is destroyed, and its peaceful abodes changed into desolation. Moreover, this very expedition afforded me the best opportunity of convincing the rulers of Bórnu of the injury which such a perverse system entails upon themselves.
