Published in 1918 by the United States Shipping Board. Hardcover, 244 pages, 4 1/4 by 6 1/4 inches. Officially titled "Manual for the Guidance of Apprentices on Training Ships", and written by Captain Eugene O'Donnell. Issued by the recruiting service of the Sea Training Bureau of the United States Shipping Board. The manual seems to include everything that you might want, or need, to know as a new merchant seaman, from the types of ships to nautical terms, from engine operation and types of rope knots to "how to revived an apparently drowned person". If you are confused about which side of the boat is "port" and which side is "starboard", you can find the answer in the "Nautical Dictionary" at the back of the book, along with the definitions of such terms as "booby hatch", "frap", and "weather" (well, okay, that last one you probably know). The book is illustrated with photographs, drawings, diagrams, and even color plates of various signal flags. Excellent condition for a volume that is now a century old.
