“Run up again along the thirty-third degree of longitude to the opening of Lake Oukéréoué, at the point where Lieutenant Speke had to halt.”
“I am there; a little more, and I should have tumbled into the lake.”
“Very good! Now, do you know what we have the right to suppose, according to the information given by the tribes that live along its shores?”
“I haven’t the least idea.”
“Why, that this lake, the lower extremity of which is in two degrees and thirty minutes, must extend also two degrees and a half above the equator.”
“Really!”
“Well from this northern extremity there flows a stream which must necessarily join the Nile, if it be not the Nile itself.”
“That is, indeed, curious.”
“Then, let the other point of your dividers rest upon that extremity of Lake Oukéréoué.”
“It is done, friend Ferguson.”
