e equal to English potatoes.

_11th February, 1870._--First of all it was proposed to go off to the
Lualaba in the north-west, in order to procure _Holcus sorghum_ or dura
flour, that being, in Arab opinion, nearly equal to wheat, or as they
say "heating," while the maize flour we were obliged to use was cold or
cooling.

_13th February, 1870._--I was too ill to go through mud waist deep, so I
allowed Mohamad (who was suffering much) to go away alone in search of
ivory. As stated above, shelter and nyumbo proved beneficial.

_22nd February, 1870._--Falls between Vira and Baker's Water seen by
Wanyamwezi. This confirms my conjecture on finding Lualaba at a lower
level than Tanganyika. Bin Habib went to fight the Batusi, but they were
too strong, and he turned.

_1st March, 1870._--Visited my Arab friends in their camp for the first
time to-day. This is Kasessa's country, and the camp is situated between
two strong rivulets, while Mamohela is the native name, Mount Bombola
stands two miles from it north, and Mount Bolunkela is north-east the
same distance. Wood, water, and grass, the requisites of a camp abound,
and the Manyuema bring large supplies of food every day; forty large
baskets of maize for a goat; fowls and bananas and nyumbo very cheap.

_25th March, 1870._--Iron bracelets are the common medium of exchange,
and coarse beads and cowries: for a copper bracelet three large fowls
are given, and three and a half baskets of maize; one basket three feet
high is a woman's load, and they are very strong.

The Wachiogone are a scattered tribe among the Maarabo or Suaheli, but
they retain their distinct identity as a people.

The Mamba fish has breasts with milk, and utters a cry; its flesh is
very white, it is not the crocodile which goes by the same name, but is
probably the Dugong or Peixe Mulher of the Portuguese(?). Full-grown
leeches come on the surface in this wet country.

Some of Katomba's men returned with forty-three tusks. An animal with
short horns and of a reddish colour is in the north; it is not known to
the Arabs(?).

Joseph, an Arab from Oman, says that the Simoom is worse in Sham
(Yemen?) than in Oman: it blows for three or four hours. Butter eaten
largely is the remedy against its ill effects, and this is also smeared
on the body: in Oman a wetted cloth is put over the head, body, and
legs, while this wind blows.

_1st May, 1870._--An elephant was killed which had three tusks; all of
good
