A less well-known but easy and uplifting reading is Land of the Grasshopper Song. There is a 2nd edition from 2011 but more reviews at Amazon are located at the page for an earlier reprint of the First Edition on Kindle.
In 1908 easterners Mary Ellicott Arnold and Mabel Reed accepted appointments as field matrons in Karuk tribal communities in the Klamath and Salmon River country of northern California. In doing so, they joined a handful of white women in a rugged region that retained the frontier mentality of the gold rush some fifty years earlier. Hired to promote the federal governments assimilation of American Indians, Arnold and Reed instead found themselves adapting to the world they entered, a complex and contentious territory of Anglo miners and Karuk families.
In the Land of the Grasshopper Song, Arnold and Reeds account of their experiences, shows their irreverence towards Victorian ideals of womanhood, recounts their respect toward and friendship with Karuks, and offers a rare portrait of womens western experiences in this era. Writing with self-deprecating humor, the women recall their misadventures as women in a white mans country and as whites in Indian country. A story about crossing cultural divides, In the Land of the Grasshopper Song also documents Karuk resilience despite seemingly insurmountable odds.
