78 MARINE REVIEW Reviews of Steel Ships, Their Construction and Maintenance, by Thomas Walton; pub- lished by J. B. Lippincott Co., Phil- adelphia and furnished by MARINE Review, Cleveland for $14.00, post- paid and in Europe by The Penton Publishing Co., Ltd., Caxton House, London, for £3. The first edition of this book came out at London in June 1901. It im- mediately established itself as one of the authoritative works on ship- building and it was widely used as a reference book by students, naval architects, ship builders and marine superintendents charged with the supervision of new construction and up-keep of existing fleets. In the preface to the first edition the author stated that it had taken four years to complete his work. Twenty-five years having passed since the first edition was published and since marked progress has been made in the science and craft of ship- building and many changes have taken place in design and practice it was thought well to bring out a revised and larger edition of the original work of Thomas Walton. This was ‘so especially in view of the fact there has been a steady demand for the book indicating that it holds a useful place in the literature of naval archi- tecture and that deep interest still exists in one of the largest and most fascinating of industries. Due to the untimely death of the author the revision has been carried on by an- other (John King), but as far as possible the general scope of the book as originally produced has been re- tained. Some of the chapters have been modified in plan and extended to in- clude present day practices. The book has also been divided into two parts. Part I is principally devoted to a study of the strength of ships a subject which is, in view of the insistence on economy of material, becoming of great importance and technical interest. Part II deals with some aspects of practical shipbuild- ' ing and the maintenance of ships. The functions of the classification society and their influence in_ the determination of the scantlings of classed ships is fully treated. Each of the principal members comprising the construction of ships is described in relation to each other and, their usual forms and connections. Ton- nage, free board, strength and re- quirements of trade are discussed as. Late Books to their influence in determining the type and structural features of ships. Certain _ practical illustrations are given of special types of ships to satisfy particular conditions. The MAURETANIA is described. Some space is devoted to sailing and auxiliary ships and to the special features of design and details of tankers. A number of other chapters are de- voted to the principal features of the design of modern ships-and their construction with particulars of de- tails of the structure, sterns, stern posts, rudders, masts, derrick posts and ventilation. Shipyard work and launching problems are also treated including modern practice in ship- building such as welding, in place of riveting. The last chapter of the book (9) deals with the after care of ships and the means of preventing rapid deterioration, the nature and causes of corrosion and the preservatives of steel, paint, cement and bituminous mixtures. The survey of ships is described in some detail and also re- pairs and renewal of steel and wood. Sell White Star Line The long talked of sale of the White Star Line has finally taken place, not to the original bidders Furness, Withy & Co. but to the Royal Mail Steam Packet Co. making the latter com- pany the largest steamship company in the world. The transaction involved the payment of £7,000,000 ($34,000,- 000) to the International Mercantile Marine Co. The sale included 21% ships under the White Star flag in the north Atlantic and Australian trades, six steamships of the Aberdeen White Star Line, 44 per cent of the seventeen steamships of the Shaw, Savill and Albion Co. operating from London to Australia via the Panama canal. The half ship is 50 per cent of the freighter DrLpnHic, the other half being owned by the Atlantic Transport Line. In the sale is also included the S. S. Laurentic, 17,000- ton passenger steamer nearing com- pletion at Harland and Wolff, for the Canadian trade, and the plans for the 62,000-ton liner OcEANIC, which have been prepared, and an order for which it was understood, had already been placed with Har- land and Wolff, though the motive power has not been definitely de- January, 1927 cided upon and construction has not yet been started. Lord Kylsant who is head of the Royal Mail Steam Packet Co. is now the most powerful shipping magnate in the world’s most powerful ship- ping country.

WHEELER was completed for the Salvage Process Corp. equipped under the Wheeler system for the pumping of oil sludge, gases and other substances from _ tanks, double bottoms, bilges and other re- ceptacles. The H. J. WHEELER formerly known as the Licut Horsr, was built in 1919 at Fore River, Mass. The WHEELER is 147 feet long, 31 feet beam, 421 tons gross and 223 tons net. She is equipped with two scotch boilers. Oil is used for fuel with the Coen oil burning system. During the last six and one-half years the Wheeler system has been operating in New York harbor. Over 6000 tanks on more than 1200 vessels have been successfully cleaned by this system. It has been demonstrated that where this system is used re- pairs and other work on oil tanks may be carried on with safety. Until Oct. 1, 1926 the patents cover- ing this system were owned by the Wheeler Salvage Co., Inc. On that. date all the Wheeler, Armstrong and Engstrand cleaning patents owned by the Wheeler company, together with the Wheeler equipment were pur- chased by the Salvage Process Corp., 80 Broad street, New York, and 224 Bush street, Brooklyn, N. Y. The Salvage Process Corp. is carrying on the work in New York harbor and endeavoring in every way to increase the efficiency of operation of the Wheeler system. Realizing that speed of operation and prompt attention are vital to ship owners and repair companies the new tug H. J. WHEELER was added to the fleet. Prior to Dec. 1, 1926 the fleet consisted of one tug and three barges, each equipped with one suction line. The recent addition is a powerful tug, which means more rapid move- ment of all the company’s vessels, and the new unit is equipped with a powerful vacuum pump and two suc- tion lines. The pumping capacity of the fleet is increased by more than one-third of its former capacity.
