But unquestionably the most popular of African explorers is Dr. Livingstone, an account of whose first expedition--1849-52--has been read by a great majority of intelligent persons speaking the English language. Large and numerous editions were speedily demanded, and Africa again became an almost universal topic of discourse. Indeed, intelligence of Dr. Livingstone’s return after so many years of toil and danger, was rapidly spread among the nations, accompanied by brief reports of his explorations, and these prepared the way for the reception of the Doctor’s great work by vast numbers of people. Every one was ready and anxious to carry the war of his reading into Africa. And afterwards, when Dr. Livingstone returned to Africa, and having prosecuted his explorations for a considerable period reports came of his death at the hands of cruel and treacherous natives, interest in exact knowledge of his fate became intense and appeared only to increase upon the receipt of reports contradicting the first, and then again of rumors which appeared to substantiate those which had been first received. In consequence of the conflicting statements which, on account of the universal interest in the subject, were published in the public press throughout the world, the whole Christian church, men of letters and science became fairly agitated. The sensation was profound, and, based upon admiration of a man of piety, sublime courage, and the most touching self-denial in a great cause to which he had devoted all his bodily and intellectual powers, it was reasonable and philosophical. It is not surprising, therefore, that the English government should have fitted out an expedition in search of Livingstone. Accordingly, the Livingstone Search Expedition, as it is called, was organized early in the winter of 1871-72, and under command of Lieut. Dawson, embarked on its destination, on the 9th of February of the last year. The expedition reached Zanzibar April 19, and the members were most kindly received by the Sultan, Sayid Bergash, and greatly assisted by his Grand Vizier, Sayid Suliman. A company of six Nasik youths, originally slaves in a part of Africa through which the Search Expedition would pass, were being drilled for the purpose, and were expected to be of great assistance.
