But I have more particular reason to be grateful for the opinion entertained of me by the British Government; for after Mr. Richardson had, in March 1851, fallen a victim to the noble enterprise to which he had devoted his life, Her Majesty’s Government honoured me with their confidence, and, in authorizing me to carry out the objects of the expedition, placed sufficient means at my disposal for the purpose. The position in which I was thus placed must be my excuse for undertaking, after the successful accomplishment of my labours, the difficult task of relating them in a language not my own.

In matters of science and humanity all nations ought to be united by one common interest, each contributing its share in proportion to its own peculiar disposition and calling. If I have been able to achieve something in geographical discovery, it is difficult to say how much of it is due to English, how much to German influence; for science, is built up of the materials collected by almost every nation, and, beyond all doubt, in geographical enterprise in general none has done more than the English, while, in Central Africa in particular, very little has been achieved by any but English travellers. Let it not, therefore, be attributed to an undue feeling of nationality if I correct any error of those who preceded me. It would be unpardonable if a traveller failed to penetrate further, or to obtain a clearer insight into the customs and the polity of the nations visited by him, or if he were unable to delineate the country with greater accuracy and precision, than those who went before him.

Every succeeding traveller is largely indebted to the labours of his predecessor. Thus our expedition would never have been able to achieve what it did, if Oudney, Denham, and Clapperton had not gone before us; nor would these travellers have succeeded so far, had Lyon and Ritchie not opened the road to Fezzán; nor would Lyon have been able to reach Tejérri, if Captain (now Rear-Admiral) Smyth had not shown the way to Ghírza. To Smyth, seconded by Colonel Warrington, is due the merit of having attracted the attention of the British Government to the favourable situation of Tripoli for facilitating intercourse with Central Africa; and if at present the river-communication along the Tsádda or Bénuwé seems to hold out a prospect of an easier approach to those regions, the importance of Tripoli must not be underrated, for it may long remain the most available port from which a steady communication with many parts of that continent can be kept up.

I had the good fortune to see my discoveries placed on a stable basis before they were brought to a close, by the astronomical observations of Dr. Vogel, who was sent out by Her Britannic Majesty’s Government for the purpose of joining the expedition; and I have only to regret that this gentleman was not my companion from the beginning of my journey, as exact astronomical observations, such as he has made, are of the utmost importance in any geographical exploration. By moving the generally-accepted position of Kúkawa more than a degree to the westward, the whole map of the interior has been changed very considerably. The position assigned by Dr. Vogel to Zínder gives to the whole western route, from Ghát through the country of Ásben, a well-fixed terminating point, while at the same it serves to check my route to Timbúktu. If, however, this topic be left out of consideration, it will be found that the maps made by me on the journey, under many privations, were a close approximation to the truth. But now all that pertains to physical features and geographical position has been laid down, and executed with artistic skill and scientific precision, by Dr. Petermann.

The principal merit which I claim for myself in this respect is that of having noted the whole configuration of the country; and my chief object has been to represent the tribes and nations with whom I came in contact, in their historical and ethnographical relation to the rest of mankind, as well as in their physical relation to that tract of country in which they live. If, in this respect, I have succeeded in placing before the eyes of the public a new and animated picture, and connected those apparently savage and degraded tribes more intimately with the history of races placed on a higher level of civilization, I shall be amply recompensed for the toils and dangers I have gone through.

My companion, Dr. Overweg, was a clever and active young geologist; but, unfortunately, he was deficient in that general knowledge of natural science which is required for comprehending all the various phenomena occurring on a journey into unknown regions. Having never before risked his life on a dangerous expedition, he never for a moment doubted that it might not be his good fortune to return home in safety; and he therefore did not always bestow that care upon his journal which is so desirable in such an enterprise. Nevertheless, almost all his observations of latitude have been found correct, while his memoranda, if deciphered at leisure, might still yield a rich harvest.

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.

But besides this, it was of the utmost importance to visit the country of the Músgu; for while that region had been represented by the last expedition as an almost inaccessible mountain-chain, attached to that group which Major Denham observed on his enterprising but unfortunate expedition with Bú-Khalúm, I convinced myself on my journey to Ádamáwa, from the information which I gathered from the natives, that the mountains of Mándará are entirely insulated towards the east. I considered it, therefore, a matter of great geographical importance to visit that country, which, being situated between the rivers Shárí and Bénuwé, could alone afford the proof whether there was any connection between these two rivers.

I shall have frequent occasion to refer, in my journal, to conversations which I had with the natives on religious subjects. I may say that I have always avowed my religion, and defended the pure principles of Christianity against those of Islám; only once was I obliged, for about a month, in order to carry out my project of reaching Timbúktu, to assume the character of a Moslem. Had I not resorted to this expedient, it would have been absolutely impossible to achieve such a project, since I was then under the protection of no chief whatever, and had to pass through the country of the fanatic and barbarous hordes of the Tuarek. But though, with this sole exception, I have never denied my character of a Christian, I thought it prudent to conform to the innocent prejudices of the people around me, adopting a dress which is at once better adapted to the climate and more decorous in the eyes of the natives. One great cause of my popularity was the custom of alms-giving. By this means I won the esteem of the natives, who took such a lively interest in my well-being that, even when I was extremely ill, they used to say, “ʿAbd el Kerím[1] shall not die.”
