J. C. Bidwill's Rambles in New Zealand (London, 1841) and Dr E. Dieffenbach's Travels in New Zealand (London, 1843) deal with the interior of the North Island. For W. B. D. Mantell's geological survey of north Otago the best source is the Quarterly Journal of the Geological Society (1850). The many important expeditions undertaken by Sir Julius von Haast are systematically outlined in his Geology of Canterbury and Westland (Christchurch, 1879). The Otago Daily Times, 9–18 February, 19–20 March 1863 contains excellent articles describing the expedition of Sir James Hector from Lake Wanaka to the Arawata river, and the Otago Provincial Gazette, vol. vi, contains a full report of his expedition from Martin's Bay to Lake Wakatipu. Useful articles by page 196Hector and von Haast appeared in the Journal of the Royal Geographical Society (1864).
