While Underhill's work is considered influential, it's important to note that his perspective is rooted in the historical context of his time, which may reflect outdated biases.
Here are some other books written by Harold A. Underhill:
* "The Indian in American History" (1949)
* "The Mountain People" (1953)
* "The Navajo" (1956)
These books provide valuable insights into the history of the American West and the experiences of Native Americans. However, it's important to engage with these works critically, considering the historical context and potential limitations of Underhill's perspective.
