The first thing to note about this book is that it is small, only the size of a paperback. The blurb on the inside of the dust jacket declares that this is one of four volumes to be published in a series, Merchant Ships of the World in Color, "a pictorial survey of the merchant ship - ocean liner, tramp steamer, freighter, tanker - and its development during the last one hundred years". The introduction is an essay about the design, appearance and use of merchant ships between 1910 and 1929, "the period covered by this book was one of particular interest and variety...various borrowings from the era of sail still showed in many of the older steamers...The advent of the First World War cut right across the hitherto steady line of evolution...born of the war were many new ideas...actual hull design, the grouping of deckhouses and superstructure, new cargo handling gear and alternative forms of propulsion." The most obvious attraction in the book is the set of 96 color plates, each one illustrating a different ship, "each has been chosen either for her own particular interest or as repesentative of a particular type or hull layout". Each illustration also includes a depiction of the house flag for the shipping line, which brings me to the less obvious, but equally worthwhile, attraction of the text! Each ship has slightly more than a page of text describing its characteristics, and outlining the history of the vessels in that class. The print is small, which is good news in such a small book - plenty of information is packed into a small space! At the back of the book there is a section of diagramatic comparisons, so you can get a better idea about the various design features described. There is also a list of ships illustrated, grouped according to nationality, and another list grouped according to type and trade. Finally, there is a list of all the ships in the book, including all those mentioned in the text.
