COMMENTS OF THE PRESS. 



Those familiar with Professor Ketchum's book on Steel Mill Buildings will welcome 

 this pioneer treatise on bin design, which is characterized by the same thoroughness, clear- 

 ness and logical and systematic arrangement displayed in the former volume. ... A 

 valuable feature of the book is to be found in the tables of costs of actual structures which 

 are included wherever possible and analyzed so thoroughly as to be of the greatest assistance 

 and value. For practical data and scientific and theoretical accuracy, Prof. Ketchum's 

 book can be recommended to the student and practicing engineer alike. The Engineering 

 Magazine, November, 1907. 



This book will be welcomed by the constructing engineer as the first authoritative 

 and elaborate contribution to technical literature on the perplexing subject of the design 

 and construction of coal and ore bins. . . . The portion of the book which relates to 

 coal and ore bins is the largest, and this will make it appeal especially to mining and metal- 

 lurgical engineers. They will find the admirable study of retaining walls to be scarcely 

 less useful. 



Professor Ketchum is well known as the author of "The Design of Steel Mill Build- 

 ings," which won high appreciation because of its eminently practical character. His 

 present work is one of the same order, and will take a high place. The Engineering and 

 Mining Journal, June 8, 1907.
