It would be tiresome to enumerate in detail all the little acts which were performed by us while following out our instructions. As a rule, whenever the steamer stopped to take in wood, or for any other purpose, Dr. Kirk and Charles Livingstone went ashore to their duties: one of our party, who it was intended should navigate the vessel and lay down the geographical positions, having failed to answer the expectations formed of him, these duties fell chiefly to my share. They involved a considerable amount of night work, in which I was always cheerfully aided by my companions, and the results were regularly communicated to our warm and ever-ready friend, Sir Thomas Maclear of the Royal Observatory, Cape of Good Hope. While this work was going through the press, we were favoured with the longitudes of several stations determined from observed occultations of stars by the moon, and from eclipses and reappearances of Jupiter's satellites, by Mr. Mann, the able Assistant to the Cape Astronomer Royal; the lunars are still in the hands of Mr. G. W. H. Maclear of the same Observatory. In addition to these, the altitudes, variations of the compass, latitudes and longitudes, as calculated on the spot, appear in the map by Mr. Arrowsmith, and it is hoped may not differ much from the results of the same data in abler bands. The office of "skipper," which, rather than let the Expedition come to a stand, I undertook, required no great ability in one "not too old to learn:" it saved a salary, and, what was much more valuable than gold, saved the Expedition from the drawback of any one thinking that he was indispensable to its further progress. The office required attention to the vessel both at rest and in motion. It also involved considerable exposure to the sun; and to my regret kept me from much anticipated intercourse with the natives, and the formation of full vocabularies of their dialects. I may add that all wearisome repetitions are as much as possible avoided in the narrative; and, our movements and operations having previously been given in a series of despatches, the attempt is now made to give as fairly as possible just what would most strike any person of ordinary intelligence in passing through the country. For the sake of the freshness which usually attaches to first impressions, the Journal of Charles Livingstone has been incorporated in the narrative; and many remarks made by the natives, which ho put down at the moment of translation, will convey to others the same ideas as they did to ourselves. Some are no doubt trivial; but it is by the little acts and words of every-day life that character is truly and best known. And doubtless many will prefer to draw their own conclusions from them rather than to be schooled by us. CHAPTER I.
