It may be- noted that Vermont led in talc production in 1917, the 

 grade of talc, however, being low. In the production of granite and 

 marble it leads, and in slate it is second only to Pennsylvania.

An Annotated Index of Minerals of Economic Value, to Accompany 

 a Bibliography of Indian Geology and Physical Geography. 

 Compiled by T. H. D. la Touche, M.A., F.G.S., Fellow of the 

 Asiatic Society of Bengal. Calcutta: Geological Survey of 

 India, 1918. Pp. 490. 



The purpose of the author is to furnish a guide to the Hterature on 

 Indian minerals of economic importance and at the same time to indicate 

 as concisely as possible the nature of the information given by each of 

 the various writers. These notes (Part II) are supposed to be used in 

 conjunction with the bibliography which forms Part I of the work. 

 The minerals are arranged alphabetically, or frequently under group 

 heads where they are chemically or economically related to one another.

The Geology of the Tuapeka District, Central Otago Division. By 

 P. Marshall, M.A., D.Sc, F.G.S. New Zealand Department 

 of Mines, Geological Survey Branch, Bulletin No. 19 (N.S.). 

 Pp. 72, pis. 12. 



This report consists of a description of the general geology and 

 physiography of the region, together with its various cultural and natural 

 features. The formations present include the pre-Jurassic Tuapeka 

 series, which, so far as now known, may be of any age between pre- 

 Cambrian and Jurassic, and the Waitahuna series of Upper Cretaceous 

 and Lower Eocene age, together with some Pleistocene and Recent 

 deposits. The Tuapeka series represents deposits of httoral sands and 

 muds and the Waitahuna true marine sediments, with some associated 

 volcanic s. 



The chief economic resource of the region is gold, which occurs 

 disseminated in conglomerate beds or as lodes. It is beUeved to be 

 primary in the conglomerate. Other minor mineral resources include 

 antimony, copper, cinnabar, and scheelite.
