It begins with ship- yard organization, and follows the work through step by step with detailed ex- planations and copious notes on the duties of each worker. The progress of the ship is traced from the time the first keel plate is laid, through the construction of the hull, the launching and fitting out of the propelling machinery and other equipment. Every tool used in the shipyard is written up in non-technical language which the aver- age mechanic can easily understand. It is a complete work by a practical man dealing entirely with the practical side of shipbuilding, and will enable the ship worker to obtain a firm grasp on the things that are going on around him daily. : CONTENTS Shipyard Organization; Division of work; Shipyard Tools; Shipways; Keels; Shell Plating; Frames; Floors; and Longitudinals; Tank Top, Inner Bottom and Peak Tanks; Stem Stern Post and Rudder; Bulkheads and Hatches; Hold Stanch- ions and.Foundations; Deck Beams and Plating; Ship Fittings; Joiner Work; Launching; Engine Room and Engines; Boiler Room and Boilers; Propellers; Auxiliary Machinery; Piping Systems; Hull Engineering; Engine Dock Trial; Ship Nomen- clature; A Glossary of Terms and Phrases. 156 ill. 2 folding plates 544 x 734 inches—flexible fabrikoid 246 pages Price $3.00, Postpaid THE PENTON PUBLISHING COMPANY Book Department Penton Bldg.
