Lac Tchad
Lake Chad, in French Lac Tchad, is a freshwater lake in Central Africa, surrounded by Chad, Cameroon, Niger, and Nigeria. The lake is very shallow and was historically very large, though it has shrunken significantly from its former size.

Phase 1
London Considered as a Great World. (The Great World of London): "Moreover, the localities of St. Benetfink, and St. Benetsherehog, or even Bevis Marks, in the heart of the City, are as much terra incognita, to the great body of Londoners themselves, as is Lake Tchad in the centre of Africa to all but the Landers or Dr. Barths of our race."
