The importance of the subject treated in this volume can be appre- 

 ciated when it is known that the products of the mines of the United 

 States alone in the census year of 1889 amounted to ^587,230,662, and 

 that this amount really only represents the interest on an immensely 

 larger capital invested. The mining products of the United States are 

 far more important in their aggregate value than those of any other 

 country in the world, though, in many individual products, other coun- 

 tries supply more than the United States. This country is first, how- 

 ever, in the production of pig iron and steel. It is also first in the 

 production of copper, gold, silver, petroleum, and a number of other 

 products. Great Britain is still the leader in the production of coal, 

 but the United States' production is rapidly growing and already equals 

 81.08 % of the British production, and supplies 28.75% of the world's 

 consumption. 



Every subject in this volume is fully discussed, and at the same time 

 nothing is given which is not appropriate and even necessary. Thus a 

 combination of completeness and conciseness is reached which is excel- 

 lent. Among the most carefully and exhaustively treated subjects are
