rebellion against him. At Akra-at^n, the last village 
belonging to that chief on the left bank, and which is 
probably inhabited by the same tribe as Onech^h, Obi 
took sanguinary vengeance some years ago for the 
murder of one of his relatives. 
These hills decline towards the south-east. A little 
rivulet, about seventy yai'ds wide, descending from them, 
was passed very close. The water in it appeared to be 
stagnant, owing probably to the cessation of supply 
from the hills: or, at all events, its current was 
overcome by the superior^volume of the Niger. The 
shores of this little stream were well wooded, and had a 
beautiful aspect. The left bank, near its mouth, was 
seen in the low season of 1832, and then appeared to 
be formed of rock. 
In this part of the river, were many Pistia floating 
separately, but higher up towards the confluence, we met 
them in large quantities.* This plant appears to have 
been displaced by rising waters from its tranquil domicile, 
as is frequently the case with others ; for we saw several 
small floating islands of grass and other plants, clumps 
of roUed-up herbage, and stems of large trees lying hori- 
zontally, with their roots and branches partly emerging 
from the water — in the distance, exactly like canoes. The 
water is very muddy, of clay colour, the shores low, 
covered with brushwood, intermixed with so many 
creepers, as to form, sometimes for a great distance, a 
vegetable wall. This was particularly remarkable on 
* These were seen in vast numbers in the Chadda, when beginning 
to rise, in 1833 ; but few were in the Niger above the couiiuence.
