Reviews of Late Books Stability and Seaworthiness of Ships, by T. B. Abell, O. B. E. pro- fessor of naval architecture in the University of Liverpool, 297 pages, 5144 x 8% inches; published by the University Press of Liverpool, Ltd., Hodder and Stoughton, Ltd., London and furnished by MariNE Review for $5.00 postpaid and in Europe by the Penton Publishing Co., Ltd., Cax- ton House, London for 18 shillings net. This book, for all that it is written by one of Great Britain’s leading scientists in naval architecture, gives consideration to those practical prob- lems affecting a ship’s stability and seaworthiness which the shipmaster may be called upon to deal with or consider in the ordinary routine of his calling. The subject of stability is treated in such a manner as to render the book valuable also to marine engi- neer officers who although they are not responsible for the loading of ships, have in their charge the many appliances which are used for se- curing stability. Therefore, a knowl- edge of stability such as they may gain from this book will be of serv- ice to them also. The first several chapters of the book describe the movements of the center of gravity and the center buoy- ancy of the ship during ordinary loading operations. After the detail knowledge of these factors has been obtained the general problem of equi- librium is discussed. It is felt that this is the best way to meet the requirements of readers unfamiliar with the subject. Throughout all calculations only the simpler alge- braic and trigonometrical expressions are used and which are familiar to the reader. There is also kept con- stantly before him the mechanical ‘or physical meanings of the expres- sions used. The stable ship is dealt with in the main portion of the book but the complicated and disconcerting be- havior of an unstable ship is also presented in a simple manner and precautions are suggested in endeavor- ing to rectify a list due to sta- bility. The book contains many prac- tical diagrams and tables and is well printed on good stock. There are eleven chapters, the head- ings which may be enumerated as follows: 1. Weight and Center of Gravity; 2. Buoyancy and Center Buoyancy; 8. Equilibrium and Sta- bility; 4. Experimental Determina- 32 tion of Stability; 5. The Ship in Motion; 6. Special Cargoes; 7. Load- ing and Ballasting; 8. Trim; 9. Small Stability and Negative Sta- bility; 10. Sea Worthiness; 11. Es- timates of Areas and Volumes and of Centers of Gravity or Centers of Figure of Areas and Volumes; Appendix. * O* * Ports and Terminal Facilities, by Roy S. MacElwee; cloth, 446 pages, 6 x 9 inches fully illustrated; pub- lished by McGraw-Hill Book Co., Inc. and furnished by MARINE REVIEW, Cleveland, for $5.00 net, postpaid, and in Europe by The Penton Publishing Co., Ltd., Caxton House, London, for 25 shillings net. The author of this valuable book, Roy S. MacElwee, Ph. D., commis- sioner of port development for the Port of Charleston, S. C., is widely recognized as an authority on port development and terminal facilities. Ports and Terminal Facilities gives a thorough and detailed discussion of marine terminal facilities. Though it is, in a sense, a second edition of the book of the same title by the same author which appeared in 1918 it is completely rewritten and _ so much enlarged that it is virtually a new book. It discusses the problem of material equipment of ocean gate- ways from the point of view of low cost of maintenance and _ operation through proper design to suit the par- ticular trade for which such equip- ment is being developed. Traffic conditions are analyzed and studied in their relation to port facili- ties for best service. Part I of Ports and Terminal Fa- cilities contains four chapters as fol- lows: The Nature of the Problem, which is sub-divided into subjects such as, the importance of port facili- ties in national defence, and in trans- portation, the nation’s second largest industry, freight costs at sea, range of competition; General Characteris- tics of a Well Co-ordinated Sea Port; Wharf Design—Quay Piers and Other Types, in two chapters. Part II dis- cusses general cargo wharf equip- ment in eight chapters with the fol- lowing headings: General Cargo Transfer—Winches, Derricks, Cranes, Conveyors; Transfer and Handling of Uniform Sizes of Packages or Special Freight; The Transit Shed; Transit Shed Equipment; Marine Terminal Track Arrangements and Drayways; The Width of the Wharf Apron; The Port Terminal Warehouse (in two chapters). Part III covers port ter- minal facilities other than general cargo (passengers, bulk, industries). There are five chapters in this part of the book with the following head- ings: Ocean Passenger Terminals Bulk Freight-Ore; Bulk Freight-Coal; Bulk Freight—Liquids and Grain; The Industrial Harbor and Upland Development. In appendix A_ the British regulations against the dis- charge of oil in navigable waters is published in full. From the Editor s Mail To the Editor: In your article on page 36 of the March MARINE REVIEW under the caption “Launch Second Carferry at Manitowoc,” you state the Carferry GRAND RAPIDS is now operating in the transport of railway cars across Lake Michigan between Benton Har- bor and Milwaukee. This_ should read between Grand Haven and Mil- waukee. The Grand Trunk railway have since put the carferry MADISON in service so that there are now operating four carferries between Grand Haven and Milwauke2, each making two trips every 24 hours. In addition to this the Wisconsin & Michigan Transportation Co. oper- MARINE REVIEW—May, 1927 ate break-bulk freight and passenger steamers between Grand Haven and Milwaukee maintaining all the year around service. The Goodrich Transit Co. do the same between this port and Chicago. The Construction Ma- terials Co. have headquarters here for their large fleet of steamers, op- erating from their gravel plant here, and the United States Engineer office maintain headquarters here for the Dredge GEN. G. G. MEADE and other dredges and smaller crafts so that we do not feel that we should be mixed up in a journal like the MA- RINE REVIEW with some other port of lesser importance.
