to both the author and the enterprising Survey of Alabama. It is 

 more than that; it is a very notable indication of the rapid progress 

 which Alabama is making in iron making. An examination of the report 

 shows this progress strikingly. Over a hundred pages of new matter have 

 been added and chapters on Coal and Coal Washing, Concentration of 

 Low-Grade Ores and Basic Steel and Basic Iron, indicate the lines of 

 progress. The first edition of the report was intended for a general 

 treatment from the point of view of raw materials. The new edition, 

 by the addition of much valuable matter, has become as well almost a 

 manual on iron making from low grade ores and is accordingly of 

 much wider usefulness. In bringing together widely separated tech- 

 nical papers and adding to the material so much from the results of 

 his own laboratory, Dr. Phillips has placed all interested in the subject 

 in his debt. It is unfortunate that so good a report should be pre- 

 sented in such poor form. The paper, press work, and proof reading 

 leave much to be desired. H. Foster Bain.
