The ship and its contents are a time capsule of mid-nineteenth-century America, rich with information about the history of industry, technology, and commerce in the Trans-Missouri West. In addition to enumerating the items the boat was transporting to Montana, and offering a photographic sample of the merchandise, Switzer places the Bertrand itself in historical context, examining its intended use and the technology of light-draft steam-driven river craft. His account of steamboat commerce provides multiple insights into the industrial revolution in the East, the nature and importance of Missouri River commerce in the mid-1800s, and the decline in this trade after the Civil War.
Switzer also introduces the people associated with the Bertrand. He has unearthed biographical details illuminating the private and social lives of the officers, crew members, and passengers, as well as the consignees to whom the cargo was being shipped. He offers insight into not only the passengers' reasons for traveling to the frontier mining camps of Montana Territory, but also the careers of some of the entrepreneurs and political movers and shakers of the Upper Missouri in the 1860s. This unique reference for historians of commerce in the American West will also fascinate anyone interested in the technology and history of riverine transport.
