Mohamad sowed rice yesterday, and has to send his people (who were unsuccessful among the Balégga) away to the Metambé, where they got ivory before.

I cannot understand very well what a "Theoretical Discoverer" is. If anyone got up and declared in a public meeting that he was the theoretical discoverer of the philosopher's stone, or of perpetual motion for watches, should we not mark him as a little wrong in the head? So of the Nile sources. The Portuguese crossed the Chambezé some seventy years before I did, but to them it was a branch of the Zambezi and nothing more. Cooley put it down as the New Zambesi, and made it run backwards, up-hill, between 3000 and 4000 feet! I was misled by the similarity of names and a map, to think it the eastern branch of the Zambezi. I was told that it formed a large water in the south-west, this I readily believed to be the Liambai, in the Barotsé Valley, and it took me eighteen months of toil to come back again to the Chambezé in Lake Bangweolo, and work out the error into which I was led—twenty-two months elapsed ere I got back to the point whence I set out to explore Chambezé, Bangweolo, Luapula, Moero, and Lualaba. I spent two full years at this work, and the Chief Casembe was the first to throw light on the subject by saying, "It is the same water here as in the Chambezé, the same in Moero and Lualaba, and one piece of water is just like another. Will you draw out calico from it that you wish to see it? As your chief desired you to see Bangweolo, go to it, and if in going north you see a travelling party, join it; if not, come back to me, and I will send you safely by my path along Moero."

The central Lualaba I would fain call the Lake River Webb; the western, the Lake River Young. The Lufira and Lualaba West form a Lake, the native name of which, "Chibungo," must give way to Lake Lincoln. I wish to name the fountain of the Liambai or Upper Zambesi, Palmerston Fountain, and adding that of Sir Bartle Frere to the fountain of Lufira, three names of men who have done more to abolish slavery and the slave-trade than any of their contemporaries.

[Through the courtesy of the Earl of Derby we are able to insert a paragraph here which occurs in a despatch written to Her Majesty's Foreign Office by Dr. Livingstone a few weeks before his death. He treats more fully in it upon the different names that he gave to the most important rivers and lakes which he discovered, and we see how he cherished to the last the fond memory of old well-tried friendships, and the great examples of men like President Lincoln and Lord Palmerston.]

"I have tried to honour the name of the good Lord Palmerston, in fond remembrance of his long and unwearied labour for the abolition of the Slave Trade; and I venture to place the name of the good and noble Lincoln on the Lake, in gratitude to him who gave freedom to 4,000,000 of slaves. These two great men are no longer among us; but it pleases me, here in the wilds, to place, as it were, my poor little garland of love on their tombs. Sir Bartle Frere having accomplished the grand work of abolishing slavery in Scindiah, Upper India, deserves the gratitude of every lover of human kind.

"Private friendship guided me in the selection of other names where distinctive epithets were urgently needed. 'Paraffin' Young, one of my teachers in chemistry, raised himself to be a merchant prince by his science and art, and has shed pure white light in many lowly cottages, and in some rich palaces. Leaving him and chemistry, I went away to try and bless others. I, too, have shed light of another kind, and am fain to believe that I have performed a small part in the grand revolution which our Maker has been for ages carrying on, by multitudes of conscious, and many unconscious agents, all over the world. Young's friendship never faltered.

"Oswell and Webb were fellow-travellers, and mighty hunters. Too much engrossed myself with mission-work to hunt, except for the children's larder, when going to visit distant tribes, I relished the sight of fair stand-up fights by my friends with the large denizens of the forest, and admired the true Nimrod class for their great courage, truthfulness, and honour. Being a warm lover of natural history, the entire butcher tribe, bent only on making 'a bag,' without regard to animal suffering, have not a single kindly word from me. An Ambonda man, named Mokantju, told Oswell and me in 1851 that the Liambai and Kafué rose as one fountain and then separated, but after a long course came together again in the Zambezi above Zumbo."

8th October, 1870.—Mbarawa and party came yesterday from Katomba at Mamohela. He reports that Jangeongé (?) with Moeneokela's men had been killing people of the Metamba or forest, and four of his people were slain. He intended fighting, hence his desire to get rid of me when I went north: he got one and a half tusks, but little ivory, but Katomba's party got fifty tusks; Abdullah had got two tusks, and had also been fighting, and Katomba had sent a fighting party down to Lolindé; plunder and murder is Ujijian trading. Mbarawa got his ivory on the Lindi, or as he says, "Urindi," which has black water, and is very large: an arrow could not be shot across its stream, 400 or 500 yards wide, it had to be crossed by canoes, and goes into Lualaba. It is curious that all think it necessary to say to me, "The Manyuema are bad, very bad;" the Balégga will be let alone, because they can fight, and we shall hear nothing of their badness.

10th October, 1870.—I came out of my hut to-day, after being confined to it since the 22nd July, or eighty days, by irritable ulcers on the feet. The last twenty days I suffered from fever, which reduced my strength, taking away my voice, and purging me. My appetite was good, but the third mouthful of any food caused nausea and vomiting—purging took place and profuse sweating; it was choleraic, and how many Manyuema died of it we could not ascertain. While this epidemic raged here, we heard of cholera terribly severe on the way to the coast. I am thankful to feel myself well.

Only one ulcer is open, the size of a split pea: malachite was the remedy most useful, but the beginning of the rains may have helped the cure, as it does to others; copper rubbed down is used when malachite cannot be had. We expect Syde bin Habib soon: he will take to the river, and I hope so shall I. The native traders reached people who had horns of oxen, got from the left bank of the Lualaba. Katomba's people got most ivory, namely, fifty tusks; the others only four. The Metamba or forest is of immense extent, and there is room for much ivory to be picked up at five or seven bracelets of copper per tusk, if the slaves sent will only be merciful. The nine villages destroyed, and 100 men killed, by Katomba's slaves at Nasangwa's, were all about a string of beads fastened to a powder horn, which a Manyuema man tried in vain to steal!
