What metaphors are used in Last of the Breed by Louis L'Amour?

Heritage is an underlying metaphor in the narrative. Joe Mack finds the value in his heritage long before he finds himself in a prison camp in Siberia. Throughout his childhood, he listened and learned what his Indian grandfather was teaching him about his people. Mack would spend his holidays living in the mountains just like his ancestors had done before him. He was taught not only how to live off the land, but also the values his people held dear. For instance their spirit of generosity, this value and others would help to save Mack's life in the taiga.
