Augustus and his brothers Francis and Henry left Yule's Station (60 miles north-east of Perth) on August 7, 1846 with four horses and seven weeks' provisions and explored a considerable amount of the country north of Perth. The party returned after 47 days, having covered 953 miles. Two years later there was an expedition to examine the course of the Gascoyne River in order to find good pasture land; further explorations followed during his time as Assistant Surveyor of Western Australia. In 1857 he also led a party in a search for traces of Ludwig Leichhardt, a fellow explorer who had disappeared. Both Augustus and his brother were presented with gold medals by the Royal Geographical Society. This facsimile reprint of the 1884 original is a fascinating diary of their adventures and explorations.
