_4th October, 1870._--A trading party from Ujiji reports an epidemic
raging between the coast and Ujiji, and very fatal. Syde bin Habib and
Dugumbe are coming, and they have letters and perhaps people for me, so
I remain, though the irritable ulcers are well-nigh healed. I fear that
my packet for the coast may have fared badly, for the Lewale has kept
Musa Kamaal by him, so that no evidence against himself or the dishonest
man Musa bin Saloom should be given: my box and guns, with despatches, I
fear will never be sent. Zahor, to whom I gave calico to pay carriers,
has been sent off to Lobemba.

Mohamad sowed rice yesterday, and has to send his people (who were
unsuccessful among the Balegga) away to the Metambe, 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 Chambeze 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 Barotse Valley, and it took
me eighteen months of toil to come back again to the Chambeze 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
Chambeze, 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 Chambeze, 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 gi
