PROFESSOR SMITH'S JOURNAL. 311 
We had only a confined view of the river, the prospect 
being obstructed by the mountains, which appeared some- 
what higher to the east. The river runs in a winding 
course between them. They form columns rounded at the 
top with fragments of quartz, which sometimes form veins 
and beds in the slate. We found here some scattered 
shrubs of Eugenia, and two or three species of grass. We 
rowed up opposite Congo Binda, which is situated at some 
distance inland, and high upon the platform of a mountain. 
We went on shore and followed a rugged ravine, whose 
sides consist of a compact mica-slate. . . . . . We 
observed the traces and excrements of several kinds of 
animals ; chiefly, however, antelopes ; but we did not get 
a sight of any of them. I walked over some flatly-rounded 
rugged hills, on which only a few shrubs were growing. I 
attempted in vain to get a view of the windings of the river 
as far up as the cataract. ‘The mountains are of the same 
form, and are seen to a great distance, undulating with 
sloping declivities, and frequently intersected by deep 
ravines. ‘The level parts are luxuriant, but the sides and 
tops of the mountains are naked. I descended the ravine 
through climbers and shrubby plants, almost all of which 
left me in uncertainty as to their genus, and regretting, as 
usual, our coming here so late in the year. I followed 
another ravine, intersected with numerous narrow but deep 
holes, which generally makes the ravines very difficult to 
walk in. I met Lockhart amidst a thicket, in which were 
several lofty trees, but almost all of them were in fruit. We 
discovered an Arum foliis 3-nat. dichotomis ; the root of
