Query: Bungle through the jungle

Over the Andes and through the jungle to ineptness we go. A quite humorous account of science gone jumbled. But not all is lost here.In 1923 eight scientists plus the author venture through the South American mountains and rainforests to make further discoveries in their respective fields of study. Touted as, "The most perfectly equipped expedition that has ever started to explore South America", it quickly unfolds into a blundering journey with many problems and mishaps.Thanks to MacCreagh's sense of humor and wit we see how every imaginable incident went from bad to worse. One by one these scientists quit the expedition to forsake the author and one other to travel up the remote Uaupes and Tiquie Rivers meeting face to face with hostile natives. What transpires is a remarkable short term study into the culture of these indigenous peoples.Entertaining read.
