That Hard Hot Land: BotanicalCollecting Expedition in the Anglo-Egyptian Sudan, 1933-1934

摘要

Between December 1933 and April 1934 three very different men travelled 6000 miles through western and southern Sudan by train, motor car, lorry, river steamer, donkey, and on foot. The expedition aimed to investigate the relationship between the vegetation and soil through a strip of country with similar temperatures but with great variations in rainfall.
