African rivers which I have seen. The others 
had at least some trees growing on their banks, 
but here there were none, nor are they to be seen, 
till its junction with the Cradock. Some of the 
pools which it forms have been found to be forty 
feet deep, and afford comfortable retreats for the 
sea-cow. 
About four days' journey above the junction of 
the Sea-cow with the Cradock, the latter great 
river is formed by the confluence of two others 
of considerable magnitude, the one flowing from 
the E., and the other from the S. E. as I heard from 
a boor who had seen them. It is very probable 
these streams derive their sources from the chain 
of mountains which constitute the western 
boundary of Caffraria, and are reported to be so 
numerously infested by very savage wild Bush- 
men, as to prevent the CafFres from molesting 
their neighbours in that direction. This predatory 
people have generally been obliged to come round 
by the southern end of that range of mountains 
on the verge of the colony, which they can 
easily do without being observed by the colonists.
