ountry which I have described, no POSITIVE change had as
yet taken place in the general feature of the interior. The river
continued to flow in a direction somewhat to the northward of west,
through a country that underwent no perceptible alteration. Its waters,
confined to their immediate bed, swept along considerably below the level
of its inner banks; and the spaces between them and the outer ones, though
generally covered with reeds, seemed not recently to have been flooded;
while on the other hand, they had, in many places, from successive
depositions, risen to a height far above the reach of inundation. Still,
however, the more remote interior maintained its sandy and sterile
character, and stretched away, in alternate plain and wood, to a distance
far beyond the limits of our examination.

About the 21st, a very evident change took place in it. The banks of the
river suddenly acquired a perpendicular and water-worn appearance. Their
summits were perfectly level, and no longer confined by a secondary
embankment, but preserved an uniform equality of surface back from the
stream. These banks, although so abrupt, were not so high as the upper
levels, or secondary embankments. They indicated a deep alluvial deposit,
and yet, being high above the reach of any ordinary flood, were covered
with grass, under an open box forest, into which a moderately dense scrub
occasionally penetrated. We had fallen into a concavity similar to those
of the marshes, but successive depositions had almost filled it, and no
longer subject to inundation, it had lost all the character of those
flooded tracts. The kind of country I have been describing, lay rather to
the right than to the left of the river at this place, the latter
continuing low and swampy, as if the country to the south of the river
were still subject to inundation. As the expedition proceeded, the left
bank gradually assumed the appearance of the right; both looked water-worn
and perpendicular, and though not more than from nine to ten feet in
height, their summits were perfectly level in receding, and bore
diminutive box-timber, with widely-scattered vegetation. Not a single
elevation had, as yet, broken the dark and gloomy monotony of the
interior; but as our observations were limited to a short distance from
the river, our surmises on the nature of the distant country were
necessarily involved in some uncertainty.

THREATENED ATTACK--AMICABLE CONFERENCE.
