Whither Africa? Much of the continent's exploration was by intrepid gentleman scientists who wanted to map the unknown. But it was slow going. Even maps from the late 19th century bear significant blank areas. The idea of mapping Africa seems easy enough today, but in the 19th century everything had to be done by hand. Navigating and surveying involved cumbersome often sensitive instruments that all had to be portered to unknown regions. The hazards were legion: diseases such as malaria, yellow fever and sleeping sickness, wild animals, strange languages, exposure to all weathers, and hostile native tribes and belligerent Arab traders. Yet, slowly but surely, more gaps were filled, and the interior of the continent was unveiled. The maps here tell the storyas you go from older to more recent maps you will see how more and more of "Darkest Africa" became less and less unknown.
