Racked with fever, virtually broke and earning a precarious living through sending back to London the plumes of beautiful birds, Wallace (1823-1913) ultimately became one of the most heroic and admirable of all scientist-explorers. Whether living with Hill Dyaks or hunting Orang-Utans or sailing on a junk to the unbelievably remote Aru islands, Wallace opens our eyes to a now long vanished world. "Great Journeys" allows readers to travel both around the planet and back through the centuries - but also back into ideas and worlds frightening, ruthless and cruel in different ways from our own. Few reading experiences can begin to match that of engaging with writers who saw astounding things: great civilisations, walls of ice, violent and implacable jungles, deserts and mountains, multitudes of birds and flowers new to science. Reading these books is to see the world afresh, to rediscover a time when many cultures were quite strange to each other, where legends and stories were treated as facts and in which so much was still to be discovered.
