'This is an account of a zoographic reconnaissance through the Brazilian hinterland.' (Theodore Roosevelt) In this book Theodore Roosevelt describes the scientific discovery, scenic tropical vistas, and exotic flora and fauna experienced during the Roosevelt-Rondon Scientific Expedition into the Brazilian jungle he attended in 1913. Roosevelt was one of the most famous presidents of the United States of America. But his achievements as a naturalist, explorer, hunter, author, and soldier though are as much a part of his fame as any office he held as a politician.
