The first book I remember reading that involved travel to far flung locations was one written by an old colonial hand, Fred G Merfield, with the alluring title ‘Gorillas were my Neighbours’. Looking back, I now see it as the memoirs of a casual racist, (amazingly quite acceptable at the time), with caricatures of tribal rituals, cannibalism and bush meat in Equatorial Africa. However, it was a considerable eye-opener for an eleven year old boy and certain phrases from it still loiter in my mind.
‘Water, water everywhere, nor any drop to drink’, as the Ancient Mariner bemoaned. Of course he was surrounded by seawater, but for a large number of the world’s people the same issue of lack or inability to use water dogs their lives. Simple bonds of hydrogen and oxygen (H2O), create one of nature’s most incredible substances. With properties so constant in some ways that our metric system of weights and volume is based on it; one litre of water weighs a kilogram, one cubic metre of water weighs a tonne.
