REVIEWS 
The Cost of Mining. By James R. Fintay. Third’ edition (en- 
tirely revised, enlarged, and reset). McGraw-Hill Book Co., 
1920. 
The new edition of this standard work on mining costs in addition 
to amplifying and bringing up to date the data on mining costs found 
in the earlier editions, contains a considerable amount of material of 
broader economic interest relating to mineral resources. Chapter I, 
for example, discusses mineral wealth as a source of national power, 
chapter III treats of the nature and use of capital. 
The cost of mining data is presented seriatim by mineral commodities 
and covers coal, iron, copper, lead, silver-lead, zinc, gold, and silver. 
The chapter dealing with each of these is commonly prefaced by some 
general discussion and by statistics of production. Cost data for 
iron-mining relate only to the Lake Superior region. 
In the chapters devoted to copper occur such paragraph headings as 
‘Geologic Unconformities at Jerome,” ‘“‘Characteristics of Belt Rocks,” 
“Theories of Formation of Jerome Deposits,” etc.; the book is therefore 
somewhat broader in scope than its title would suggest. The book 
commends itself not only to the engineer but to the economist, geologist, 
or geographer concerned in the réle of mineral resources in the industrial 
life of the United States.

rates of chapters from the ioneone Handbook. 
This mining handbook is a worthy attempt to furnish to ie 
interested in mining in Western Australia a large amount of varied 
information likely to prove of service to them in the exploitation of 
mineral deposits. The handbook includes chapters on the relations of 
physiography and of petrology to the exploitation of mineral deposits, 
chapters expounding the mining regulations and explaining various 
methods of governmental assistance to prospecting and mining. Then 
follow chapters dealing with the major base metals, with the various
