Reviews of Late Books ae Manual of Naval Architecture, by George Charles Manning, M. S. cloth, 183 pages 5% x 8% inches; published by D. Van Nostrand Co. Inc., New York and supplied by MARINE REVIEW, Cleveland for $2.75 plus 15 cents post- age, and in Europe by the Penton Publishing Co. Ltd. Caxton House London, for 12s 9d postage extra. This book is prepared primarily for operating officers, students and all those who wish to become familiar with the subject of naval architecture without any extensive previous know- ledge of it. It is written in a very clear and readable style and is illus- trated by simple diagrams and inter- esting examples. This book is pre- pared for operating officers and on that account is different from most other works on the subject which have been prepared for those engaged in the design and construction of ships. The aim of the author has been to cover all the features of a hull. In the presentation of the subject mat- ter, reference to difficult mathematics has been avoided as far as possible. Anyone with a knowledge of element- ary algebra and trigonometry requi- site for navigation should be able to follow through the very simple mathe- matical treatments presented in this book. The opening section of the book presents definitions of the vari- ous parts of the vessel. In other sec- tions of the book the subjects of cal- culation of areas, etc., the problems of displacement, equilibrium, compu- tation of metacentrie radius, condi- tions and occurences affecting stabil- ity and others are covered. In addition there are practical examples which will help the student to a better under- standing of this subject. This book should be of greatest value to every- one interested in ships. 1930 Johnson’s Steam Vessels and Motor Ships Manual, cloth, 309 pages, 8% x 4% inches published by Hads Johnson, M. E. Inc. New York, and supplied by. Marine Review, Cleveland for $1.00 plus fifteen cents postage and in Europe by the Penton Publish- ing Co. Ltd., Caxton House London, for 5s postage extra. This book is a directory of all American-owned and _ self-propelled commercial vessels. There is an index in the front of the book giving alpha- betically the name of the vessel with the name of the owning company. There is also an alphabetical list of owners, which gives the name of all vessels owned, the date and place they were built, the type and dimen- sions of hull, the gross and net ton- nage, the type and horsepower. of the engine, and the type and dimensions of the boiler. In the back of the book 62. there are some interesting designs of typical vessels which should be found very useful by owners. Motorship Manual, by A. B. Newell and J. Kuttner, fabrikoid, 288 pages 7 x 10 inches, published by National Trade Journals, Inc. New York City, and supplied by Marine REVIEW Cleve- land, for $5.00 plus 15 cents postage and in Europe by the Penton Publish- ing Co. Ltd., Caxton House, London, for 25s postage extra. This book is an engine room guide, catalog, and register of American do- cumented diesel vessels, and is a real textbook of operation. The numerous chapters on American diesel practice cover every phase of the subject in a way that every operator can under- stand. On this account it should prove of great assistance to those taking a test for an operator’s license. Over 100 pages of this book have been devoted to a practical explanation of the tech- nical fundamentals of diesel engine operation and construction. It is only within recent years that the technical essentials of the diesel engine have become sufficiently stabilized to per- mit collecting such data as are in- cluded in this manual. The various chapters include: Recent motor ves- sel construction, properties of the die- sel engine; airless injection, cooling and maintenance of pistons, two cycle engine details, etc. A special feature of the 1930 edi- tion is the list of American docu- mented diesel vessels. This list is broken down into groups such as tankers, cargo-and-passenger vessels, freighters, fishing vessels, tugs, ferry boats, yachts, etc. The name, gross tonnage, power, year built, and the name and address of the owner of each boat are given. Another interest- ing feature of the work is a section showing up-to-date illustrations and specifications of the leading marine diesel engines on the American mar- ket. Weld Design and Production, by Robert E. Kinkead; cloth, 108 pages, 5% x 8% inches; published by Ron- ald Press Co., New York, and sup- plied by Marine Review, Cleveland, for $4, plus 15 cents postage; in Eu- rope by Penton Publishing Co. Ltd., Caxton House, London, for 20s, post- age extra. Lack of organized data on welding, though a great deal has been devel- oped, led the author to undertake this work. It was his aim not only to collect these data but to corelate them and organize the fundamentals of welding. The book is designed pri- marily for engineers responsible for satisfactory and safe welds and exe- MARINE REVIEW—September, 1930 cutives responsible for cost of welding jobs. Safety in welded structures, the all- important factor, is covered in discus. sion of weiding procedure control. In this discussion the way is shown to eliminate probability of weld failures Welds need no longer be uncertain and unsafe, the author claims, for the probability of failure can be brought to zero. In the many more possible applications of welding, not now useq_ the weld should be designed for the job and carried on with sufficient pre. cision to assure uniform results, A chapter is devoted to the reasons for welding, one to how welds are made and others to effects of physica] conditions on weld behavior, actual welding conditions, weiding procedure control machine welding and _ ye. search and development. Numerous il- lustrations include charts, photomicro- graphs and diagrams. The text is fully indexed to facilitate reference. elements Cost of Shipbuilding by M. Francis Carr, cloth 245 pages, 5% x 7% inches, published by Theo. Gaus’ Sons, Inec., New York City and fur- nished by MArRInr Review, Cleveland, for $3, plus 15 cents for postage and in Europe by the Penton Publishing Co. Ltd., Caxton House, London. In preparing the data for this volume, the author has attempted to provide a short method in calculating the cost of the many different types of merchant vessels, and to eliminate the practically obsolete system of figuring this class of work. While the book is concerned chiefly with merchant vessels, it is nevertheless true that a great deal of the subject matter will apply equally well to war vessels. To simplify the work of figuring the various parts of the vessel, sketches of the different mem- bers have been drawn, detailing many parts of the hull structure, locating the rivet holes in the plates and shapes, etc. A 12,000-ton deadweight capacity cargo vessel has been se- lected as an example, as vessels of this size and type will be mostly used as cargo carriers in future. To arrive at an approximate figure of the total ‘cost of the vessel, the author has treated each plate, shape, etc., separately. According to the scheme, every piece of material that goes into the construction of the vessel has a fixed weight of material, the number and weight of rivets, the weight and cost of all machinery, etc., in fact, the cost and weight of all items that go into the complete ship are computed. The approximate cost of passenger vessels, tug boats, river boats, barges, tanks, drydocks, etc., the repairing of damaged vessels, the cost of building a shipyard, and many other items relative to the cost of building ships will be found in the pages of this book.
