The Royal Fisk Gold Rush Letters are collection of over 900 original manuscript letters from the Cariboo Gold Rush period, 1862-1868.  Written by Victoria area merchants to Royal Fisk, a forwarding and shipping agent in San Francisco, the letters are a valuable source of information on trade and commerce as it developed in Victoria during the height and decline of the Cariboo Gold Rush.

In addition to the letters from Victoria merchants, the collection includes correspondence from merchants in New Dungeness and Port Angeles, Washington County, Portland, California and Montana.  It also contains bills of exchange, telegrams, and a series of letters related to the Fisk Hotel in Silver City, California (now the Alpine Hotel).
