Preface.

It has been my object in this work to give as clear an account as I was able of tracts¹ of country previously² unexplored, with their river systems, natural productions, and capabilities⁴; and to bring before my countrymen, and all others interested in the cause of humanity, the misery⁵ entailed⁶ by the slave-trade in its inland phases; a subject on which I and my companions are the first who have had any opportunities of forming a judgment⁷. The eight years spent in Africa, since my last work was published, have not, I fear, improved my power of writing English; but I hope that, whatever my descriptions want in clearness, or literary skill, may in a measure be compensated⁸ by the novelty of the scenes described, and the additional information afforded on that curse of Africa, and that shame, even now, in the 19th century, of an European nation — the slave-trade.

I took the “Lady Nyassa” to Bombay for the express purpose of selling her, and might without any difficulty have done so; but with the thought of parting with her arose, more strongly than ever, the feeling of disinclination to abandon the East Coast of Africa to the Portuguese⁹ and slave-trading, and I determined¹⁰ to run home and consult my friends before I allowed the little vessel¹¹ to pass from my hands. After, therefore, having put two Ajawa lads, Chuma and Wakatani, to school under the eminent¹² missionary¹³ the Rev³. Dr. Wilson, and having provided satisfactorily for the native crew, I started homewards with the three white sailors, and reached London July 20th, 1864. Mr. and Mrs. Webb, my much-loved friends, wrote to Bombay inviting¹⁴ me, in the event of my coming to England, to make Newstead Abbey my headquarters, and on my arrival renewed their invitation: and though, when I accepted it, I had no intention of remaining so long with my kind-hearted generous friends, I stayed with them until April, 1865, and under their roof transcribed¹⁵ from my own and my brother’s journal the whole of this present book. It is with heartfelt gratitude¹⁶ I would record their unwearied kindness. My acquaintance with Mr. Webb began in Africa, where he was a daring and successful hunter, and his continued friendship is most valuable because he has seen missionary work, and he would not accord his respect and esteem¹⁷ to me had he not believed that I, and my brethren also, were to be looked on as honest men earnestly trying to do our duty.

The Government have supported the proposal of the Royal Geographical¹⁸ Society made by my friend Sir Roderick Murchison, and have united with that body to aid me in another attempt to open Africa to civilizing¹⁹ influences, and a valued private friend has given a thousand pounds for the same object. I propose to go inland, north of the territory which the Portuguese in Europe claim, and endeavour to commence that system on the East which has been so eminently²⁰ successful on the West Coast; a system combining the repressive efforts of H.M. cruisers with lawful²¹ trade and Christian²² Missions — the moral and material results of which have been so gratifying. I hope to ascend²³ the Rovuma, or some other river North of Cape²⁴ Delgado, and, in addition to my other work, shall strive, by passing along the Northern end of Lake Nyassa and round the Southern end of Lake Tanganyika, to ascertain²⁵ the watershed²⁶ of that part of Africa. In so doing, I have no wish to unsettle what with so much toil²⁷ and danger was accomplished²⁸ by Speke and Grant, but rather to confirm their illustrious discoveries.

I have to acknowledge the obliging readiness of Lord Russell in lending me the drawings taken by the artist who was in the first instance attached to the Expedition. These sketches²⁹, with photographs by Charles Livingstone and Dr. Kirk, have materially assisted in the illustrations. I would also very sincerely thank my friends Professor Owen and Mr. Oswell for many valuable hints and other aid in the preparation of this volume.
