Arrival at Boma. 
IOI 
Rio do Jacare, a narrow sedgy stream on the right 
bank, which, winding northward through rolling 
lines of hills, bends westward, and joins, they say, 
the Rio Lukullu (Lukallo ?) of Cabinda Bay. Men 
have descended, I am told, three leagues, but no 
one has seen the junction, consequently there may 
be a portage between the drains. If not, this is the 
apex of the greater Congo delta, a false formation, 
whose base between Cabinda Bay (S. lat. 5 0 25') 
and Ambrizette (S. lat. y° 16') measures i° 51', 
equal to 111 direct geographical miles, whilst its 
depth inland would be sixty.
