James G. Swan (1818-1900) was a Boston shipfitter who left his family to join the California Gold Rush. He didn't like it, so he moved to Shoalwater Bay (now called Willapa Bay) in what is now Washington state in order to raise oysters with Indian labor and sell them in California (a site of the local Chamber of Commerce says that the bay still produces 15% of the nation's oyster crop). The book is a straightforward narrative of his life on the shores of the bay in 1852-1855 in the company of a few white settlers and many more Native Americans. In fact, most of the book is ethnography of the Indians Swan came into contact with: their children's games, their adult games of chance, their burial customs, their manner of hunting seals, their method of making canoes, their superstitions, and so on. By the 1850s the Indians have had quite some contact with the white society and the global economy: women generally wore calicos; only old women preferred traditional cedar-bark skirts; men hunted with firearms; they had Chinese-made camphorwood chests in their houses. Swan learned at least two Native American languages: Chehalis, a Salishan language, and Chinook Jargon, a trade pidgin. He wonders why the Indians, who live in roughly the same conditions, speak so many languages; in fact we now know that languages of four families were spoken between the Columbia river and the Strait of Juan de Fuca in the 1800s: Salishan, which extended all the way to Missoula, Wakashan, the languages of which are also spoken on Vancouver Island and the nearby coast, and two tiny ones: Chinookan and Chimakuan. Of course as of 2015 all of these languages are extinct or nearly so, the descendants of their speakers having switched to English.
Besides ethnography, the book also has quite some natural history of what was then wilderness: the bushy-tailed woodrat, which steals things from humans to use in its nest; different species of waterfowl that nest in the bay; gigantic salmon, which was staple food to the Indians; a stranded whale, which the Indians stripped for blubber; among the animals Swan and his friends shot there was a lynx, otters and a bear. During a Fourth of July celebration Swan and his friends made a bonfire, which proceeded to burn down the forest until rain stopped the fire.
Overall, I'd say that this is a pretty boring book. I found the narrative of John Jewitt, who was a captive of Indians at Nootka Sound, 250 miles north of where Swan lived, in 1803-1805, much more interesting. I think that this is because Jewitt the captive was much younger than Swan the oysterman, and was able and willing to assimilate into Indian society to a much greater degree, and although he escaped from the Indians, was able to describe them more as an insider would, compared to Swan.
