Note 173 — Chapter VII
Reading edition
A ridge stretches to the south, through the middle of South Africa, and forms an impenetrable barrier between the two coasts. M. Correa de Serra informs me, that the Portugueze in Congo and Angola, have never been able to penetrate to the coast of the Indian ocean.
Mr. Bruce learnt (Vol. iii. p. 668.) that a high chain of mountains from 6° runs southward through the middle of Africa. He supposes the gold of Sofala to be drawn from these mountains. (p. 669.)
