Mattox 300 Pages. 6x9, 16 Portraits, 30 Illustrations with Charts The book traces the work of the corporation from its organization up to and through the first post- armistice year. The author was in close personal contact with the men charged with the work of defeating the submarine campaign and he uses the opportunity thus offered to show the extent of the problems faced by the organizers of the Emergency Fleet Corporation. The development of the various agencies organized to carry out this work of shipbuilding, the carly problems of organization which had to be ironed out and the final whipping into form for efficient ship production are records of accomplishments which make up the bulk of the book. In this intimate study of the work of each branch of the corporation, the book will prove of great interest to the large number of persons associated with war shipbuilding not only with the Emergency Fleet Corporation but in all private shipyards. The book is more than a historical review of the war activities of a federal department. It is a story of a successful American business enterprise which encountered and overcame problems common to most industrial organizations. .
