With wit and charming powers of description, Marryat paints a picture of American entrepreneurial genius in this rich land–rich in virgin soils as well as gold–for the busy immigrants building a new life in this recent addition to the Union. Marryat arrived in San Francisco on May, 4 1850 to witness the last burning embers from a disastrous fire–the second out of seven which would devastate the infant city between December 1849 and June 1851. With manservant and three dogs he made his way north via Benicia, Napa and Sonoma until he reached Don Raymonds estate where he was an honored guest. Continuing to Russian River he finds a small paradise to build a small farmstead, taking in hunting and exploration as he goes. Eventually returning to San Francisco he arrives in time to witness the sixth fire–that of May 3-4, 1851, which killed a friend and also destroyed all of his possessions stored in the friends warehouse, including his journals, paintings and sketches–for apart from being a skilled narrator Marryat was an artist of considerable ability. The narrative then takes in the diggings and with rich description gives witness to the drinking, gambling, lawlessness and the lynching of the gun law society
