Book excerpt: Sir Douglas Mawson, Australia's greatest Antarctic explorer, made four trips to the Antarctic: in 1907-09 with Shackleton's British Antarctic Expedition; in 1911-14, having declined to join Scott's ill-fated Antarctic journey, as leader of the Australasian Antarctic expedition; and twice between 1929 and 1931 as leader of the British, Australian and New Zealand Antarctic Research Expedition (BANZARE). Mawson's Antarctic Diaries brings together for the first time all his descriptive writings while in the Antarctic. An uncensored record of events, they reveal Mawson's innermost thoughts at times of great stress and conflict on ship and on shore, through achievement and failure, joy and tragedy. This book includes some of Frank Hurley's most famous Antarctic photographs, as well as some not reproduced before.
