thological region than the Zambesi. Guinea-fowl and francolins are
in abundance, and so indeed are all the other kinds of game, as
zebras, pallahs, gnus.

_19th December, 1866._--I got a fine male kudu. We have no grain, and
live on meat alone, but I am better off than the men, inasmuch as I
get a little goat's-milk besides. The kudu stood five feet six inches
high; horns, three feet on the straight.

_20th December, 1866._--Reached Casembe,[40] a miserable hamlet of a
few huts. The people here are very suspicious, and will do nothing but
with a haggle for prepayment; we could get no grain, nor even native
herbs, though we rested a day to try.

After a short march we came to the Nyamazi, another considerable
rivulet coming from the north to fall into the Loangwa. It has the
same character, of steep alluvial banks, as Pamazi, and about the same
width, but much shallower; loin deep, though somewhat swollen; from
fifty to sixty yards wide. We came to some low hills, of coarse
sandstone, and on crossing these we could see, by looking back, that
for many days we had been travelling over a perfectly level valley,
clothed with a mantle of forest. The barometers had shown no
difference of level from about 1800 feet above the sea. We began our
descent into this great valley when we left the source of the Bua; and
now these low hills, called Ngale or Ngaloa, though only 100 feet or
so above the level we had left, showed that we had come to the shore
of an ancient lake, which probably was let off when the rent of
Kebra-basa on the Zambesi was made, for we found immense banks of
well-rounded shingle above--or, rather, they may be called mounds of
shingle--all of hard silicious schist with a few pieces of fossil-wood
among them. The gullies reveal a stratum of this well-rounded shingle,
lying on a soft greenish sandstone, which again lies on the coarse
sandstone first observed. This formation is identical with that
observed formerly below the Victoria Falls. We have the mountains
still on our north and north-west (the so-called mountains of Bisa, or
Babisa), and from them the Nyamazi flows, while Pamazi comes round the
end, or what appears to be the end, of the higher portion. _(22nd
December, 1866.)_ Shot a bush-buck; and slept on the left bank of
Nyamazi.

_23rd December, 1866._--Hunger sent us on; for a meat diet is far from
satisfying: we all felt very weak on it, and soon tired on a march,
but to-day we hurried on to Kavim
