to agree with most of the features of the moon. We cannot, 

 however, enter into further details or explanations that are given 

 of various other objects, interesting though they be. We can 

 only quote one of the concluding paragraphs, as this gives some 

 idea of the difference in conclusions which result from the study 

 when compared with those of other authors. He says: "This 

 sketch of the life of our nearest neighbor has but little in com- 

 mon with the accounts of other biographers. To her has been 

 ascribed a fiery youth, after the manner of the sun, a middle life 

 of dissipation, like Jupiter and Saturn, a hardening and wrink- 

 ling old age, toward which the earth is tending, and finally, the 

 end of change — death. If the record of her scarred face has 

 now been read aright, all that remains of the old narrative is the 

 denouement : the moon is dead." Joseph F. James. 



The Mineral Industry. Its Statistics, Technology, and Trade, 

 in the United States and other countries from the earliest 

 times to the end of 1892. "Vol. I. Edited by Richard P. 

 Roth well. New York, The Scientific Publishing Company. 

 1893. 638 p. 

 In the years of 1874-75 and '76 The Engineering and Mining 

 Journal of New York published the first complete reports of the 

 coal production of the United States, and in 1889 as special gov- 

 ernment agent for the census, the editor of the journal, Mr. 

 Richard P. Rothwell, collected the statistics of gold and silver. 

 The scope was gradually extended until in January, 1892, a mag- 

 nificent volume of statistics was given to the world and universal 

 encomium heaped upon the journal and its staff for their vponder- 

 ful work. Indeed such was the unstinted praise accorded it we 

 can but wonder what language will be used for the present vol- 

 ume, no longer a supplementary number in journal form, but a 

 handsome library volume of 628 pages. It is the intention to 

 make this the first of a series to embrace within a few years the 

 statistics and technology of the mineral interests of the world, in 

 many cases going back historically to the earliest times and always 



carried down to the date of publication. Such a vast undertak- 

 ing lias heretofore been considered impracticable for private en- 

 terprise and has been relegated to the unlimited resources of 

 governments, it is worthy to note, however, thai simultaneously 

 with the issue of this volume containing all statistics accurately 

 and systematically recorded for 1892, there appears the govern- 

 ment publication of similar character for the year 1891. The in- 

 troduction to this latter volume, by the way, speaks of " the im- 

 possibility of concluding a complete canvas of the products of 

 huge industries like coal, iron ores, and building stone without a 

 considerable delay after the close of the year reviewed," and yet 

 the Engineering and Mining Journal, depending entirely upon 

 personal courtesy and confidence for its success, has accomplished 

 this feat so impossible to the expensive machinery of government. 

 The journal is fortunate in possessing a large and carefully 

 framed staff, and in being in communication with experts in all 

 branches of industry the world over, but more than this is needed, 

 and much praise is due to all connected with the enterprise. 

 Especially is praise due to Mrs. Sophia Braeunlich, that able 

 financier and business manager of The Engineering and Mining 

 Journal, and to Mr. Richard P. Rothwell, editor of both journal 

 and " statistics." 



To attempt even a running review of this work would be out 

 of the question, the table of contents alone occupying ten pages 

 of small print. SufSce it to say that without exception the arti- 

 cles therein contained are written by men pre-eminently fitted for 

 their best treatment, and in all cases by experts in each particular 

 line. Among the contributors are : Dr. George Lunge, Dr. Fran- 

 cis Wyatt, author of " The Phosphates of America " ; E. O. 

 Leech, Director of the U. S. Mint; Professor J. F. Kemp, George 

 F. Kunz, J. Langeloth, Dr. Thomas M. Chatard, Richard E. 

 Chism. H. O. Hofraan, Emile Delecroix, and many others of 

 equal fame. Tney have been well chosen, and we congratulate 

 them upon the part they have played in this most admirable 

 work. C. P,
