There are several maps showing the distribution of land and water 

 in New South Wales at particular geological periods, and the 

 frontispiece is a clearly-printed, general, geological map of the State. 

 Finally, a glossary (a merciful provision when such words as ' regolith ' 

 and ' monadnock ' are used) and an index complete this useful 

 handbook.

1. The Production of Graphite in 1913. By E. S. Bastin. 

 Mineral Resources of the United States, year 1913. Part II. 

 pp. 181-251. 1914. 



rilHIS report contains all the information on graphite which has 

 L appeared in earlier reports of the United States Geological 

 Survey, amplified and brought up to date wherever possible. It 

 includes a valuable account of the physical and chemical properties 

 of graphite, and of the origin and uses of the mineral. The deposits 

 of the United States are described in detail, and descriptions are also 

 given of graphite deposits in Ceylon, Korea, Madagascar, and Mexico. 

 The report is completed by a full bibliography of literature bearing 

 on the occurrence, production, properties, and uses of graphite. 



2. Useful Minerals of the United States. Compiled by Samuel 



Sanford and Ralph W. Stone. United States Geological Survey, 

 Bulletin 585. pp. 250. Washington, 1914. 



Lists of useful minerals appeared in the issues of the Mineral 

 Resources of the United States for the years 1882 and 1887, but have 

 not been published since. In the interval the mining industry of the 

 United States has increased enormously, and a revised list has long 

 been called for. In view of its length it is now issued as a separate 

 publication. It gives the looality of the principal deposits of useful 

 minerals in the various States, and a glossary showing the composition 

 and character of each mineral and its principal occurrences is added.

 Mines, for the Calendar Year 1913. pp. ix 4- 544. Ottawa,

This report, which is unusually belated even for an official return, 

 testifies to the extent and varied nature of the work undertaken by 

 the Survey. During the year it was exceptionally heavy owing to 

 the additional field work called for in connexion with the handbooks 

 compiled for the visit of the International Geological Congress the 

 following year (1913). Field work in Canada appears to be not 

 without danger ; one of the staff, Dr. J. D. Trueman, unfortunately 

 lost his life owing to a canoe accident, and a topographer was laid up 

 in hospital for some months as the result of an encounter with 

 a grizzly bear. Some progress is reported in fitting up the Natural 

 History Museum, but is greatly handicapped by the lack of properly 

 equipped workrooms and storerooms. Mr. D. D. Cairnes completed 

 the geological section along the 141st parallel between the Yukon and 

 Porcupine Rivers, which is part of the geological section across the
