This compilation of ledgers of the fur trade years attempts to give an insight into what kind of goods were available to the trapper and gives an overview of three of the various forts of resupply that were available in different areas of the western United States. Occasionally, comments will be inserted used for the definitions to aid in understanding some of the terminology of the time period. Where opinions are expressed, they are the conjectures of the authors and can be subject to change in the future as new research is uncovered.
