This was like the answer we received long ago from the natives on the Liambai or Upper Zambesi when inquiring for its source.

"It rises in Leoatle, the white man's sea, or Metsehula." The second name means the "_grazing water_," from the idea of the tides coming in to graze; as to the freshness of the Liambai waters, they could offer no explanation.
Some again thought that the Nile rose in Western Africa, and after flowing eastwards across the Continent, turned northwards to Egypt; others still thought that it rose in India! and others again, from vague reports collected from their slaves, made it and several other rivers rise but of a great inland sea.
_Achelunda_ was said to be the name of this Lake, and in the language of Angola, it meant the "sea." It means only "_of_" or "_belonging to Lunda_," a country.

It might have been a sea that was spoken of on a whole, or anything.

"_Nyassi, or the sea_," was another name and another blunder.

"Nyassi" means long grass, and nothing else.
