This book by George F. Bosworth was originally published in 1915 and was the first title to appear in the Cambridge Industrial and Commercial Series. Intended for use in schools, the volume traces the development of human ingenuity in shipping from the early dug-out boat to the launching of the Aquitania. Successive chapters provide a detailed account of the work of the Royal Navy and dockyards and also consider the fishing industry and ports in Great Britain, lighthouses and lightships, their construction, distribution, and value to the shipping industry. Great seaports and their industries, together with the history and condition of the Cinque Ports are treated in the last chapters.
