Most fortunately, he still carried the greater part of these original notes till the time of his death, so that they were forthcoming when his effects were subsequently saved.
This brings us to the second instalment of the journals, for we have thus acknowledged the first to have reached us on Mr. Stanley's return.
When the battered tin travelling-case, which was with Livingstone to the last, was opened at the Foreign Office in the spring of this year, not only were these valuable papers disclosed which I have mentioned, but it was found also that Livingstone had kept a copious journal during his stay at Unyanyembé in some copy-books, and that when his stock of note-books was replenished a daily record of his subsequent travels had been made.
It was with fear and trembling that one looked to see whether all had been saved or only part, but with satisfaction and thankfulness I have subsequently discovered that his men preserved every single line, besides his maps, which now come to light for the first time.
Thus much on the material of the diaries: it remains to say a few words on the Map which accompanies these journals. It has been compiled from Dr. Livingstone's original drawings and note-books, with the corrections and additions he made from time to time as the work of exploration progressed, and the details of physical geography became clearer to him. The compiler, Mr. John Bolton[1], implicitly following the original outline of the drawing as far as possible, has honestly endeavoured to give such a rendering of the entire work, as the Doctor would have done had he lived to return home, and superintend the construction; and I take this opportunity of expressing my sincere gratification that Mr. Bolton's rare technical skill, scientific knowledge, and unwearying labour have been available for the purpose.
Amongst almost the last words that Livingstone wrote, I find an unfinished letter to myself, in which he gives me very clear and explicit directions concerning the geographical notes he had previously sent home, and I am but carrying out the sacred duty which is attached to a last wish when I call attention to the fact, that he particularly desired in this letter that no positions gathered from his observations for latitude and longitude, nor for the levels of the Lakes, &c., should be considered correct till Sir Thomas Maclear had examined them. The position of Casembe's town, and of a point near Pambetté at the S.E., and of Lake Liemba (Tanganyika), have been computed and corrected by Sir T. Maclear and Dr. Mann. The observations for latitude were taken at short intervals, and where it has been possible to test them they have been found very correct, but I repeat that until the imprimatur of his old friend at the Cape of Good Hope stands over the whole of Livingstone's work, the map must be accepted as open to further corrections.
The journey from Kabwabwata to Mparru has been inserted entirely from notes, as the traveller was too ill to mark the route: this is the only instance in all his wanderings where he failed to give some indication on his map of the nature of the ground over which he passed. The journey front Mikindany Bay to Lake Nyassa has also been laid down from his journal and latitudes in consequence of the section of this part of his route (which he left at Ujiji) not having arrived in England at this date.[2] It will be observed that the outline of Lake Nyassa differs from that on any published map: it has been drawn from the original exploratory survey of its southern shores made by Dr. Livingstone in 1861-3. For some reason this original plan was not adhered to by a former draughtsman, but the Lake has here been restored to a more accurate bearing and position.
How often shall we see in the pages of this concluding chapter of his life, that unwavering determination which was pre-eminently the great characteristic of David Livingstone!
Naturally endowed with unusual endurance, able to concentrate faculties of no ordinary kind upon whatever he took in hand, and with a dread of exaggeration which at times almost militated against the importance of some of his greatest discoveries, it may be doubted if ever Geographer went forth strengthened with so much true power. Let us add to these a sincere trust that slavery, the "great open sore of the world," as he called it, might under God's good guidance receive healing at his hands; a fervent hope that others would follow him after he had removed those difficulties which are comprised in a profound ignorance of the physical features of a new country, and we have the marching orders of him who left us in August 1865 never to return alive.
Privileged to enjoy his near personal friendship for a considerable period in Africa, and also at home, it has been easy to trace—more especially from correspondence with him of late years—that Livingstone wanted just some such gigantic problem as that which he attacked at the last to measure his strength against: that he finally overrated and overtaxed it I think all must admit.
