John McDouall Stuart (1815–66) was a surveyor and a pioneering explorer of Australia. Born in Scotland, he emigrated in 1839 to Australia where he worked in surveying and made many expeditions into the outback. The treks he undertook from 1858 to 1862 are the focus of this account, published in 1864, and are compiled from Stuart's notes by William Hardman (1828–90). During these periods of exploration he managed - though suffering from scurvy - to cross the continent, and he also discovered various rivers and geographical features. Hardman's account uses Stuart's journals to give an account of six historic and often gruelling expeditions. The first was to the north-west; the following two were explorations around Lake Torrens; the fourth was an attempt to find the centre of the territory; a fifth involved a forced retreat after an aboriginal attack; and in the final one Stuart traversed the continent.
