last junction it changed its
direction to the S.W., and increased considerably in size. The country to
the south was certainly lower than that to the north; for, although both
banks had features common to each other, the flooded spaces were much
more extensive to our left than to our right.
CHANGE OF COUNTRY.
We started on the morning of the 24th, all the lighter from having got rid
of the skiff, and certainly freer to act in case the natives should evince
a hostile disposition towards us. As we proceeded down the river, the
appearances around us more and more plainly indicated a change of country.
Cypresses were observed in the distance, and the ground on which they
stood was higher than that near the stream; as if it had again acquired
its secondary banks. At length these heights approached the river so
nearly as to form a part of its banks, and to separate one alluvial flat
from another. Their summits were perfectly level; their soil was a red
sandy loam; and their productions, for the most part, salsolae and
misembrianthemum. From this it would appear that we had passed through a
second region, that must at some time have been under water, and that
still retained all the marks of a country partially subject to flood.
INTRODUCED FROM TRIBE TO TRIBE.
We had, as I have said, passed over this region, and were again hemmed in
by those sandy and sterile tracts upon which the beasts of the field could
obtain neither food nor water. We overtook the seven deputies some time
after we started, but soon lost sight of them again, as they cut off the
sweeps of the river, and shortened their journey as much as possible.
At 2 p.m. we found them with a tribe of their countrymen, about eighty in
number. We pulled in to the bank and remained with them for a short time,
and I now determined to convince the blacks who had preceded us, that I
had not been actuated by any other desire than that of showing to them
that we were not to be intimidated by numbers, when I refused to make them
any presents after their show of hostility. I now, therefore, gave them
several implements, sundry pieces of iron hoop, and an ornamental badge of
copper. When we left the tribe, we were regularly handed over to their
care. The seven men who had introduced us, went back at the same time that
we continued our journey, and two more belonging to the new tribe, went on
a-head to prepare the the neighbouring tribe to receive us; nor did we see
anything m
