Classicly

Not much humanity for you to patronise: every thirty miles or so along the edge of the water a cluster of thatched huts providing a measure of shelter for a handful of savages who live on fish and mangoes, careless of the future, indifferent to the past. Every 300 miles or so, at a Catholic Mission, a couple of white-robed Fathers issue rosaries to their less enlightened neighbours, who until the missionaries came had to rely on amulets made of python hearts. Between these centres of human endeavour, an uncharted belt of forest fringes the lake, and climbs the sides of the great cold crater, until these slope so steep that not even a creeper can catch hold. For the last thousand feet the rock is bare.
