James McQueen's A General Plan of Steam Mail Communication between Great Britain and the Eastern and Western Parts of the World is an important work that was first published in 1838. In his book, McQueen offers a detailed plan to connect Great Britain with other parts of the world through the use of steamships. It looks at all aspects of the matter, from routes and timetables to the specifications of the right fleet. The author argues the importance of improving postal services and believes that the use of steamships will significantly reduce the time of delivery of letters and goods between Great Britain and other countries. McQueen's book is not only a technical document, but also a testimony to the beginning of a new era in the development of international postal affairs. This book is a valuable resource for those interested in the history of the postal service and the technological advances of the 19th century. McQueen's work shows his vision for the future of postal service and the role of steamships in improving that process.
