with areas examined in detail have been published as prepared. The New Zealand Journal of Science and Technology, founded in 1918, provides a more accessible and popular record for official reports than parliamentary papers, and many special reports prepared by officers of the Geological Survey are published therein. The Transactions and Proceedings of the New Zealand Institute contain much information on the geology and phyisography of New Zealand, as also do other publications of which the titles are given below in full. In the appended list the titles of papers have, for the most part, been abbreviated. Reports of Geological Explorations. (By the New Zealand Geological Survey.) 1.Hector, J., 1868. Taranaki District.
