The A BC of Iron and Steel Is just what its name implies This book describes accurately and completely, but in a simple, interesting and non-technical way, every step in the manufacture of iron and steel from the ore to the finished product. It is not intended for the technical specialist, but for the busy, practical man who wants to have a broad, general knowledge of the whole iron and steel industry. From the top of the first page to the bottom of the last, there isn’t a sentence that needs explanation, and to make everything doubly clear and understandable, over two hun- dred photographs of iron and steel mill operations and equipment have been included. Yet, although the book is semi-popular in character, it is absolutely authentic and depend- able in every detail, for every one of the sixteen authors is a recognized authority on the particu- lar branch of the trade about which he writes, and he is giving the reader a summary of what his years of study and experience have taught him. Directory of Iron and Steel Works, Including Names of Officials “The A B C of Iron and Steel” includes a complete direc- tory of all the blast furnaces, steel works and rolling mills in The first section of the directory is an alphabetically arranged list of all these plants, with the address, the products and the names of the officials listed under the name of each plant. In the second section the firms are classified according to their products, every plant being listed under the name of every article it turns out, no matter in how many lists its name may appear. The first section gives you a complete list of the iron and steel trades without duplication of names: the second section gives you complete lists of the makers of each iron and steel mill product. All this information was compiled expressly for ‘The A B C of Iron and Steel’, and was revised right down to the day the book was put on the press. $5.00 per copy, postpaid Penton’s Book News, Penton Bldg., Cleveland, Ohio Please mention THE Marine Review when writing to Advertisers May, 1915
