Bulk Cargoes, A treatise on their carriage by sea and consequent effect on the design .and construction of merchant ships, by A. C. Hardy, A.M.I.N.A.; cloth, 160 pages, 6 by 9 inches; published by D. Van Nos- trand Co. New York and furnished by MARINE REVIEW, Cleveland for $6.00 postpaid, and in Europe by the Penton Publishing Co., Ltd., Caxton House, London for 30 shillings. In this book Mr. Hardy has given to the reader a clear and important discussion on how bulk cargoes are carried and in what ways the nature of the bulk cargo has affected the design and construction of vessels. It is a valuable work to anyone in any way connected with the transport by water of bulk commodities. It is a compilation in one compact source of information which hitherto has been widely scattered. The author in his preface outlines 40 the steps leading to the preparation of this book. He points out that fre- quently questions come up of impor- tance in connection with the type of vessel used in the movement of bulk cargoes. It is as an answer to these numerous pertinent questions that the present book has been prepared. Perhaps the best way of conveying the scope of this book is to list a few of its eleven chapters as follows: The Bulk Freighter: Points of design; Stability and Trim; The Oil Tanker; The Collier; The Ore Carrier; The Grain Carrier; The Self-Unloading Freighter; Bulk Transport on Inland Waterways and Bulk Transport on the Great Lakes. - : As the author himself says in his preface in referring to this book “it has been written primarily from the point of view of the naval architect, for students of naval architecture, consultants, charterers, and under- writers, its raison d’etre being to dis- cuss the effects which the principal bulk cargoes have upon the design and construction of seagoing ships and also how the necessity for the car- riage of ‘bulk cargoes on rivers and canals has brought about special types of barges and river craft’. The book is printed in large clear type on good paper and the text is well illustrated by a number of dia- grams and photographs. It is inter- estingly written and contains a great deal of valuable information.
