_13th August, 1868._--The Banyamwezi use a hammer shaped like a cone, without a handle. They have both kinds of bellows, one of goatskin the other of wood, with a skin over the mouth of a drum, and a handle tied to the middle of it; with these they smelt pieces of the large bars of copper into a pot, filled nearly full of wood ashes. The fire is surrounded by masses of anthills, and in these there are hollows made to receive the melted metal: the metal is poured while the pot is held with the hands, protected by wet rags. _15th August, 1868._--Bin Omar, a Suaheli, came from Muaboso on Chambeze in six days, crossing in that space twenty-two burns or oozes, from knee to waist deep. Very high and cold winds prevail at present. It was proposed to punish Chikumbi when Syde bin Omar came, as he is in debt and refuses payment; but I go off to Casembe. I learn that there is another hot fountain in the Baloba country, called Fungwe; this, with Kapira and Vana, makes three hot fountains in this region. Some people were killed in my path to Casembe, so this was an additional argument against my going that way. Some Banyamwezi report a tribe--the Bonyolo--that extract the upper front teeth, like Batoka; they are near Loanda, and Lake Chipokola is there, probably the same as Kinkonza. Feeling my way. All the trees are now pushing out fresh young leaves of different colours: winds S.E. Clouds of upper stratum N.W. _29th August, 1868._--Kaskas began to-day hot and sultry. This will continue till rains fall. Rumours of wars perpetual and near; and one circumstantial account of an attack made by the Bause. That again contradicted. _(31st August, 1868.)_ Rain began here this evening, quite remarkable and exceptional, as it precedes the rains generally off the watershed by two months at least: it was a thunder shower, and it and another on the evening of the second were quite partial. * * * * * [As we shall see, he takes advantage of his late experience to work out an elaborate treatise on the climate of this region, which is exceedingly important, bearing, as it does, upon the question of the periodical floods on the rivers which drain the enormous cistern-lakes of Central Africa.] * * * * *
