A History of Ownership, Finance, and Profit

This history of Burrell & Son of Glasgow describes the way in which ship ownership and operation developed during the final years of the age of sail and the beginning of the era of steamships. Not only does the work contain background material on tramp shipping commerce, it also includes a substantial database on ship building, ownership, and operations during this period. The information will be of interest to the maritime historian since it describes this important era in detail, and to the business historian interested in the strategy and structure of the shipping industry.
