“It is somewhat surprising that in a book which is evidently designed to assist the malleable-iron industry to more scientific methods of production there is no mention of the light thrown by the microscope on the structural changes which occur in the malleablising process; nor is there any reference to the mechanical properties of the various types of iron produced.”

The motif of the book is the work of the nine regiments of American engineers, with one of which the author served. “In the writing, it has been necessary to touch on all the fields of engineer activity, because these regiments came in contact with every field, even if they did not invade each one, from constructing ports to digging and holding trenches, in all parts of France from the Atlantic to the Vosges, from the Mediterranean to Flanders. Consequently there results a brief outline of what all engineers did.” (Preface) The contents are in part: The new military engineer; America’s problem; Engineer organization; Ports; French railways; American railway operations in France; Relations with the French; Forestry; Water supply; Chemical engineers; Camouflage and other fields of engineering; Maps; Flash and sound ranging and search light detection; Artillery; Light railways; Roads; Trenches and trench warfare. There are full page illustrations, figures, maps and an index.
