Expedition to the Zambesi and its Tributaries

It has been my object in this work to give as clear an account as I was able of tracts of country previously unexplored, with their river systems, natural productions, and capabilities; and to bring before my countrymen, and all others interested in the cause of humanity, the misery entailed 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 judgment. 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 compensated 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.
